Do you want to learn sketch in Chinese painting? What about oil painting, printmaking and sculpture?

Do you need to train sketch to draw Chinese painting? What is the current situation of sketch art and sketch education in China? Reporter The Paper (www.thepaper.cn) visited experts from major art institutions and art colleges in Shanghai to discuss this topic from various aspects such as Chinese painting, oil painting, printmaking and sculpture.

Zhang Peicheng (Vice Chairman of Shanghai Artists Association):

If Chinese painting wants to draw lessons from sketch, it must be cut in the way of Chinese painting.

Do you need to train sketch to draw Chinese painting? This issue has been controversial for a long time.

Everyone has a different understanding of the connotation and extension of sketch. Personally, I think that no matter oil painting, Chinese painting, printmaking or even abstract art, they are all in modeling. If sketch is a convenient way to solve modeling problems, it should still be necessary to learn sketch. Of course, there was no concept of sketch in ancient China, but the line drawing at that time was also a kind of sketch to some extent.

Sketch is actually a kind of judgment on modeling. This is the ability to feel the object.I think this ability to feel is very important for an artist. For example, when he sees a person, a scene or a bottle, he will feel and have the impulse to express himself. If this sensibility is innate, it is also necessary to tap this potential through sketch training. Of course, there are different ways of sketching, such as passively simulating nature and actively expressing objects. In fact, Chinese painting is adapted to the latter.

Western sketch also solves the problem of space. Stereo and perspective are basic skills in oil painting. For Chinese painting, the picture is flat. Even if we want to draw more realistic Chinese painting now, this space is different from oil painting. So,If we want to learn sketch in Chinese painting, its emphasis must be different from that in western painting. Otherwise, it will bring many negative effects.

In fact, among some Chinese painters older than me, some are very successful artists, but they still encounter bottlenecks. The reason is that too many western sketches were instilled in those years, and this influence is hard to get rid of, and problems arise when they are expressed with brush and ink lines of Chinese paintings. This kind of sketch training has become a shackle, which makes the performance of Chinese painting very free. From this perspective, sketch and Chinese painting are two systems. Especially for painters who paint landscapes, flowers and birds, it is absolutely impossible to use this sketching method to train, and they can’t paint plaster like western painting, and they can even not sketch.

But from a broad perspective, the sketch of Chinese painting can be trained in another way. For example, China’s drawing characters requires strong modeling ability, so modeling training is essential. The expression of Chinese painting is written, which requires the painter to express what he wants to express in one go very skillfully. If he hesitates a little in modeling and the pen stops, his writing will be greatly affected, and his breath will be "broken" immediately. However, the modeling training of Chinese painting should not draw long-term homework, otherwise it will damage the artistic expression.

Zhang Peicheng’s sketch works

In addition, the drawing method of Chinese painting sketch should also abandon the method of completely simulating the object and drawing in an orderly way. In today’s era, we should also encourage the diversity of modeling, draw our own feelings and create freely. I think this is more in line with the requirements of art.

In fact, in ancient times, although we didn’t learn sketch in the western sense, we also learned modeling by studying mustard seed garden and earlier pastels. For example, painting flowers requires a very good understanding of the structure of flowers. Take Qi Baishi as an example. He has never drawn a western sketch, but he knows the structure of the object very well. I remember once reading a document that Qi Baishi wanted to draw a duck. He carefully studied what the other paw was like when the duck landed on the ground, and he knew it clearly.Strictly speaking, we can also understand his process of figuring it out as a kind of sketch, because he is not only figuring it out in his mind, but also showing it in writing, so this is actually a study of modeling.Therefore, for Chinese painting, the training of sketch should have its own set of methods, instead of being "led by the nose" by the object, it should not be too realistic, but should capture more meaningful shapes.

Qi Baishi’s Works (Partial)

Teachers should always inspire students’ feelings about art. If everyone has their own unique interests, they can find themselves, and our art world will be rich and colorful. Although it’s hard to do. Of course, it is also necessary for traditional learning. Otherwise, this culture will not be handed down.

Traditional Chinese painting teachers used to teach students the modeling of objects and a program when teaching. Students know what peony looks like, how many painting methods there are, and the unique formal language of Chinese painting, that is, the program of painting. I think there are advantages to this, but there are also shortcomings, that is, unless students of Chinese painting have special talents, they can leave their teachers and draw peony and bamboo that are different from their teachers, otherwise they will easily fall into a stylized mode.

In fact, creation should go out and face nature directly, and sketching is very important. Of course, subjective things can be completely integrated into one’s heart. I have seen Mr. Zhu Qizhan’s sketches, and he hooked a house with a small notebook and pen, and so on. Many things are in his heart.

I can say that people who paint bamboo now rarely go out to see real bamboo, but only from the program, so people all over the country may paint the same bamboo. The program created by our ancients was summed up against real bamboo.If we have the ability to sketch today, we can also create a new program for today’s bamboo-this program is different from the ancients, but it is connected with the roots of our national culture. And this requires the ability to shape objects.

Just after the Cultural Revolution, the Ministry of Education had a big discussion about whether Chinese painting should be sketched. Is sketch the basis of Chinese painting? I think it is definitely wrong to say that "sketch is the basis of Chinese painting". But the modeling ability of sketch can be used for reference by Chinese painting. And this kind of reference should be cut in the way of sketching in traditional Chinese painting. In my opinion, students of Chinese painting can draw with a brush when they are in sketch class. For example, painting plaster Voltaire, you can draw it like him or not, but it has a lot of brush strokes in it. In this way, the bondage of western-style sketch to Chinese painting can be greatly reduced.

Jiang Jianzhong (Director of Oil Painting Department of Shanghai Academy of Fine Arts, Ph.D.):

Sketch is a "buffet", and you can find yourself only by choosing it individually.

At present, the art scene in China is surging, but the concept of sketch teaching has lagged behind. At present, the meaning of sketch understood by the oil painting major in the Academy of Fine Arts in class is still the second-hand pirated mode of the former Soviet Union, and sketch is already a kind of "stereotyped writing" and a dogma; Placed in the background of the times, it is like salted fish in the refrigerator.

Sketch is like a swamp on the road to the other shore. If the sketch foundation is poor, the picture will be weak. However, for a long time, most of the students in domestic colleges walked into this muddy swamp, but it was difficult to extricate themselves. In the Academy of Fine Arts, sketch classes are met every day, but how to draw sketches today? Most people have not thought about it, but still follow the sketch dogma, and students learn passively. Students only know how to grind a sketch very delicately, but they don’t know how to capture features, how to shape, and how sketch is a way to recognize things. They only use models as props to sketch, which has no vitality and soul.

Students don’t know what to achieve through the rules while learning the rules of sketching.Most students enter the Academy of Fine Arts because they love painting. In the cultural class, they can’t help but smear some strokes on the textbooks and sketch some naive but vivid characters. But when they entered the classroom and faced the models, those imaginations were gone. They are lost in the baggage of "Soviet-style" sketches, and their eyes are blocked by countless blocks, tones, methods and laws, which create obstacles. Every stroke of his works is to embody these laws, but as for the vivid characteristics of the objects and his own feelings, he is numb.I think many people have this experience. When parents feed their children hard every day, the effect is often counterproductive, and the result is anorexia.

In the mode of passive education, there will also be a freak. The more students master the traditional plaster skills, the less they want to create after graduation. In our country, the sketch of college entrance examination is more exam-oriented education, and there are very few personalized things. This "publicity" criterion is very practical for knocking on the door of university, but after entering university, this sketch is unfavorable for a student to become an artist. Students should look for a "private" sketch road from their own hearts and feelings, not too much "publicity". In my opinion, students majoring in oil painting should advocate short-term homework and sketching, and train their eyes’ sharpness and modeling generalization. Capture the most vivid things in the most concise way. In fact, the growth path of ancient western masters is more about drawing short-term homework.

In fact, tradition is dynamic, and you need to "find" tradition according to your own needs.The history of eastern and western art is so long and rich, can you swallow it all? If you can’t digest it, it will be of little value to you. You can only choose the food suitable for your gastrointestinal structure by buffet. If Van Gogh goes to learn from Angel, then Van Gogh does not exist. When you discover and "digest" those "traditions", you will experience the mystery of "transformational creation" and you will gradually discover yourself.

The training of sketch is not only realized by sketching or simulating objects; More importantly, according to one’s hobbies, nature and times, one should constantly absorb and revise the history of art in terms of concepts, expression techniques and modeling, and borrow the experience of predecessors in sketching and implant it into reality.

Jiang Jianzhong’s sketch works

Due to historical reasons, many successful artists found themselves in the oil paintings of western masters after the "reform and opening up", not in sketches. Therefore, most people are more accustomed to thinking and expressing their ideas directly with oil painting materials and tools on canvas, and rarely think or explain their personal artistic views in the form of sketches. Sketch is only regarded as basic training, not an independent art. Many people completely separate creation from sketching. When sketching, it is a mode of thinking, and when creating, it is a set of mode of thinking, which sets them against each other. However, the works of such painters are hard to go far.

Therefore, sketching has been a long time for some artists, just like a student’s exam. After that, he can’t wait to dump his textbook. great escape doesn’t want to look back. Sketch belongs to a position that is hardly even marginal in China.In fact, for artists, sketch is still very important, and it is the artist’s artistic position. Sometimes the record of sketch is more appropriate, natural, simple and convenient. Sketch is an artistic note, an artist’s psychological trajectory and behavior, a front stop of creation, a part of creation and creation itself!What kind of sketch there is, what kind of oil painting there is. Such examples abound in history, such as Van Gogh, Angel, Egon Schiele, Freud and so on.

It is urgent to find your own thinking point and cultivate independent thinking ability, starting from yourself! Please choose your favorite painting style in stages from the huge menu of art history, and look for excitement! Especially when I was a student,We should constantly replace the slippers of masters, wander between art history and objects, and look for interfaces between life and history, and between modernity and tradition. Don’t put basic training in opposition to creation, there should be creative elements in basic training.Maybe this should start at the same time as the first day of laying the foundation!

By the way, in contemporary times, the modeling training of oil painting major and Chinese painting major is facing a common problem. If sketch is regarded as methodology, its meaning will be very broad. In fact, all ethnic groups in the world have their own modeling methods and uniqueness in understanding the world, but they are marginalized.

The difference between China’s traditional modeling concept and the West is that Chinese’s sculpture concept follows the painting, and the clothing lines are completely flat lines, paying attention to density, accessibility, smoothness and implication, and pursuing plane. Western painting follows the sculpture, paying attention to light and shadow, space and strength, and pursuing volume. It is for this reason that beginners advocate painting plaster statues.

Perhaps the world has always been diverse, but for various reasons, we have forgotten our traditions. Interestingly, the concept of Chinese painting specialty has appeared the thinking phenomenon of western sketch, while the west is close to the planarization of the East. In the formation of her culture, a nation is still choosing something suitable for its national development, and is always in the process of absorption, exclusion and integration. Choosing and teaching students how to find food is the most important thing.

The development of western aesthetics basically follows the development of science.The traditional concept of sketch is the result of westerners’ understanding and grasping of the natural world. However, after the popularization of photography technology, the concept of sketching to reproduce nature has been in crisis … If the history of China since the 19th century is a response to the West, can the present era finally be regarded as "the response of the West to the East"?If we bypass the strange circle of cultural opposition between the East and the West, it is possible not to fall into other people’s cultural nests or our own nests. Perhaps, what we have to do is to stand on our own soil, trace back and sort out the cultural traditions of the East and the West from our personal perspective, and integrate them to generate ourselves.

Lu Zhiping (Deputy Director of Print Art Committee of China Artists Association):

Activate the "Eighteen Martial Arts" of Sketch, and enlighten diverse and diverse creations.

The idea of sketch originated in the west. butIf sketch refers to all monochromatic paintings, then in a broad sense, the method of sketching lines with a brush in ancient China can actually be regarded as a sketch.. Even now, some people think that ink painting is a form of sketch, but it was not called that at that time. In fact, most of the early artistic creations in the world are expressed in monochrome, such as rock paintings, rubbings and so on.

Sketch is beneficial to the introduction and development of all plastic arts. For printmaking, for a long period of history, it is mainly monochrome, such as early black and white woodcuts, copperplate prints, lithographs, etc., so printmaking and sketch have a special origin. Sketch should be regarded as an important support for printmaking.

In the field of teaching, how to understand and deal with the relationship between sketch education and printmaking has always been an important topic.Before and after the "Cultural Revolution", in order to make basic teaching connect with printmaking (especially black and white woodcut) more quickly, some domestic art colleges specially designed a set of sketch teaching system at that time. They trained sketch not from light and shade, but more from structure and block. This is a special sketch specially designed for printmaking teaching.

This idea was reasonable at that time, and it was quite effective in promoting the development of printmaking at one stage. But from now on, everything has advantages and disadvantages.At that time, the basis of sketch teaching was: printmaking should have a fixed pattern-large area, big black and white, and sketch served this fixed pattern. However, when the country was opened, it was found that in fact, the forms of printmaking were various.For example, some copperplate paintings pay special attention to light and shadow, while some prints emphasize line texture and sense of form. And different sketches may inspire artists to create different styles of printmaking works, so that printmaking presents a richer look. In this way, it is one-sided to set a fixed routine for a sketch to correspond to a print from the beginning.

Lu Zhiping’s print "The Old Man"

In fact, it is the same in the creation of Chinese painting. For example, if you set the Chinese painting to use lines at the beginning, you emphasize that students should use line drawing more often, but later you find that Chinese painting can also be splashed with ink and boneless, and there are many other methods. The training method of setting the box at the beginning may become a constraint for students. On the contrary, if students are encouraged to try a variety of sketches at the beginning, they will have a broader vision no matter what kind of artistic creation they are engaged in in in the future. From this point of view, sketch is not only a means to teach students to draw, but also a training of observation method and thinking mode. Isn’t creativity advocated in all fields now? Then I think sketch can be used as a way to break through the original frame. It may be more meaningful and reasonable to practice sketch in this way.

As for the sketch examination method widely criticized in college enrollment, I think it is caused by the accumulated disadvantages in the whole education field for many years, which is completely utilitarian. Let the teacher set a model to facilitate grading and admission, and less consideration is given to whether it is beneficial to students’ future growth. Many students like me can be said to be "victims" of this educational system. Because in many cases, our print creation does not advocate to describe the object in front of us truthfully, but emphasizes creativity, so many students feel at a loss and have no direction after they arrive.

We try to let the students learn to change their original thinking that relies on describing objects by observing, summarizing, choosing, imagining, mutating and creating, and let them gradually reverse their thinking mode by using abstract methods, imaginative methods and design methods.

For example, when training students to practice composition, I will ask them: Can ten different pictures be constructed from the same theme? For example, can the same three apples be placed in a variety of ways? Can black-and-white relations be handled differently? This forces them to open their minds. When their composition is finished, I say that at this time, you can choose the one you think is the best. In fact, as long as the mind is open, the hand will keep up. Sketch and composition training are both a form of sketch, which is not only a creative means, but also a support for thinking. The later draft may not be exactly the same as the sketch composition, but it doesn’t matter. The creator can see more lines and possibilities from behind one of the lines, thus getting rid of the dependence on the object.

Of course, I think it’s beneficial to know and try any kind of sketch form, including the plaster statues widely criticized in college enrollment. In fact, there is nothing wrong with learning how to push the work deeper. The problem is that it is wrong to regard such a sketch form as the only golden rule. I think it would be great if we could master the Soviet-style rigorous observation method and step-by-step molding method, and at the same time jump out of it.

I have received this Soviet-style education before. My teacher at that time told me, "After three years, five years and ten years, you will probably realize the effect of this long-term homework on you." Now I have a deep understanding,The value of long-term sketch is not to restore the object realistically, but to let me learn to observe carefully and comprehensively;Learn to make careful and rigorous trade-offs; Learning the expression of full and proper layer-by-layer promotion can also be used to study and explore a variety of expression techniques. This is the training of ability, thinking and mentality.

In plastic arts, printmaking may be a kind of painting with particularly rich styles and techniques, so the corresponding sketch forms should also be varied. For example, there is a technique called "Merutin" in copperplate prints, which pursues rich and subtle color changes, unlike black and white woodcuts. For this printmaking technique, the Soviet-style long-term sketching work will come in handy. Eighteen kinds of martial arts have their own merits, depending on who they are suitable for and on what occasion.

Some students or schools in the west don’t attach importance to sketching and can’t draw, which should not be the object we must follow.Of course, their training methods that attach importance to thinking also have some merits, but this does not mean that "being good at hands" is wrong. Now western painting is also returning, and it is normal to go astray for a period of time, and some overcorrection is also normal. As for us, there is no need to change our minds and follow the trend, as if everyone can’t draw is the "right way", which is completely unnecessary.

Yang Jianping (Vice President of Shanghai Academy of Fine Arts, Professor of Sculpture Department, Doctoral Supervisor):

At present, sketch teaching is like smog, which is a "syndrome"

Sketch, as its name implies, is a way to describe an image in a simple and simple way. Historically, sketch and sculpture are closely related.For sculptors, sketching is a basic training, but also a way to record ideas and creative inspiration. Many sculptors leave a lot of manuscripts besides three-dimensional sculptures, such as Michelangelo and Rodin.

Michelangelo sketch

Relatively speaking, China’s traditional sculptures and paintings are different from western classical realistic styles and methods. It has unique artistic modeling styles and creative methods handed down from ancestors.The ancient sculptures in China have their own strict styles. Through the description of pastels and the dictation of written data, for example, the opening of a Buddha statue has very specific data, all of which have statutes.The East emphasizes inheritance rather than innovation, but these shapes are unique. Therefore, sketch, as a basic practice or recording creation method, has many forms in a broad sense.

Sculpture itself, due to the different cultures, materials and concepts between the East and the West, finally presents a very diversified style, even in a conceptual and installation way. As a sketch teaching, we should also keep up. Otherwise, you just train every student to draw concrete, but in the end, many people actually don’t do concrete at all. It’s not that the "academic" sketch we are learning now has no merit, but at least it’s not good for all of us to do it. There should be a distinction. For those students who insist on figuration, let them study the traditional realistic sketch well. Other students can learn from it, but there is no need to spend too much class time on it. Different students should have different training emphases.

There are various ways to sketch, for example, Bauhaus’s sketch training method is to draw structural relations. Look at the traditional masters, such as Michelangelo, Leonardo da Vinci, Holbein and Diu Lei. Those lines are beautiful and expressive. We should oppose dogma and have active thoughts and critical spirit.

Yang Jianping’s work "Jing Zhe"

Our generation learned to sketch, and they danced all the way in "red dancing shoes" and enjoyed it. We visited a place, took out a sketch book and recorded it. It was very enjoyable to start painting, and a painting took half a day. But today’s young people are different. They are willing to take out their mobile phones to take a photo and make a video, which saves time and effort. Their current inspection is more about experience, with a faster pace and more things to see. In the Internet age, such a change is sometimes understandable, but it also raises a question: What kind of basic training do we need and what kind of sketch do we want to draw? Since the birth of photography, it has been an impact on documentary painting, and the artistic expression after that is more of an idea. Do all our students still draw the same sketches like photos? There must be something wrong with this.

We usually say that the master sketches well. In fact, Leonardo da Vinci was not only a painter, but also a naturalist, a scientist and thinker. Now we always say that we should learn from the lines of masters, but people are comprehensive. A person is an artist because he is capable and thoughtful, so he can paint well.The sentence in the allusion of my skillful solution to the cow "I am in a good mood, and I am also a Taoist;" It’s very reasonable to enter the skill. Now people have to "skill" instead of "Tao", putting the cart before the horse.

This also has a lot to do with our current college entrance examination system. It is these patterned sketches that students learn all day for the exam, and they don’t know what to do after entering the university. Some people think that’s how sketches should be drawn. So the students who come in are the students the teacher wants? But if you don’t want it, who can you want? China, with such a large population, how can we get into universities without this method? The sketch of the college entrance examination is indeed widely criticized now, but it is not that simple to reform it.

The existing problems in art education are actually a "syndrome", which is related to the national conditions in China, just like the smog in China. You said that students only know how to paint plaster, and you can’t blame them. They lacked aesthetic education since childhood. On the other hand, after graduation, students in China need to find jobs for their survival and family expectations, so what they have learned has to be "practical".To some extent, the Academy of Fine Arts does not train artists in China, but solves the problem of social employment.

The syllabus clearly says "sketch head" and "still life". You must take this course even if you don’t approve it. Comparatively speaking, the postgraduate stage is relatively flexible. In a word, a series of problems such as national conditions, education system, teachers and even ideology make the teaching reform difficult.

China’s trade goes global, starting from the thirteen lines in Qing Dynasty.

China’s trade went global. From 1757 to 1842, the 13th Canton was the only "special zone" for the Qing government to trade with Europe and the United States, which made the city retain its memory and make people remember its homesickness. Guangzhou is a famous cultural city with a history of more than 2,000 years. Every street and lane has a long story, and every brick and tile has a meaningful memory. Today, Xiaobian will appreciate the heavy memory of this city with you, appreciate the spirit tradition of tolerance and openness for more than 2,000 years, and appreciate the endless literary context; Together with you, under the illumination of history, we can understand today and Guangzhou, thus strengthening our cultural self-confidence. In 1757, with the promulgation of the imperial edict on foreign trade in which Qianlong only left Guangdong Customs, the foreign trade of the Qing Dynasty was locked in the thirteenth line of Guangzhou. As the only exchange center between Chinese and Western civilizations for 85 years, it is a Chinese and foreign trading place located on the edge of the Pearl River, where foreign ships gather at the thirteen ports, and almost all major countries and regions in Asia, Europe and America have had direct trade relations with the thirteen banks. It has global trade routes to Europe, Latin America, South Asia, East Asia and Oceania. It was the only surviving node of the Maritime Silk Road under the closed-door policy of the Qing government at that time, bearing the gestation and development of modern China’s commercial economy. Although the thirteen lines have disappeared in the long river of history, their historical influence has been continuing. Two hundred years later, history once again chose Guangzhou to undertake the historical mission of "gathering customers from all over the world and selling goods from all over the world". Thirteen lines and the Canton Fair jointly compose the colorful movement of the Maritime Silk Road.It became the epitome of China’s opening to the outside world and economic development in modern times. A long scroll showing the style of the thirteen-line business hall in Qing Dynasty. Where did the thirteenth line come from? Kangxi’s sea trade gave birth to the "Thirteen Lines" and made Guangzhou "trade in one mouth". This was a scene in the 18th century-the Swedish merchant ship King Frederick was sailing off the South China Sea in China. This is a large sailboat of that era. It started from Europe and will arrive in Canton after more than a year’s voyage. In the eyes of westerners, China is a country of silk, porcelain and tea, and there are countless exquisite handicrafts, showing a profound culture. They were pleasantly surprised to find China. Fortunately, the Swedish ship escaped the stormy waves of the Cape of Good Hope, the piracy in Malacca and the threat of epidemic diseases on board, and completed the voyage with 20% staff reduction. Only half of the sailboats that set out with them can reach Guangzhou. Paying such a high price is for the maiden voyage of trade between China and Sweden. After leaving Gothenburg, Sweden, King Frederick went to Spain for the silver that was commonly used in China, and arrived at Lingding Island in Guangzhou on September 6, 1732. During the four months of berthing in Guangzhou, King Frederick ordered 151 large boxes and 1801 bundles of porcelain from more than 10 foreign firms in China, totaling 49,906 pieces. And 2183 boxes of red and green tea. After sailing from Guangzhou, King Frederick returned to Sweden after eight months. Porcelain exported in the Qing Dynasty is bright in color. At that time,Every year, hundreds of such merchant ships come from afar, enter the South China Sea of China through a long waterway, and then go north along the Pearl River to reach Guangzhou, then known as the southern gate of the Eastern Empire. In fact, during the Ming Dynasty, overseas trade was not always smooth, and the imperial court often declared a "sea ban", which lasted until the early Qing Dynasty. In the Ming and Qing Dynasties, the sea was closed for 300 years. However, Guangzhou’s ship management organization, Shiboshi, was preserved and continued to play a role in promoting cultural exchanges between China and foreign countries. The model of the Swedish merchant ship Gothenburg, which sailed to Guangzhou three times in Qing Dynasty. After Kangxi unified Taiwan Province and put down the San Francisco Rebellion, he began to consider the economic and tax balance of the whole country. He sent Shi Zhu, a cabinet university student, to Guangdong and Fujian for inspection to prepare for the sea trade. Because smuggling is popular, there is opposition in the court. Kangxi asked Shizhu, "How many houses have you been to in Guangdong?" Shizhu replied: "Zhaoqing, Gaozhou, Lianzhou, Leizhou, Qiongzhou, Guangzhou, Chaozhou, etc., where the people said that they had left their homeland for more than 20 years, and now the emperor has leveled the bandits and can go back to their homeland." Kangxi asked again, "So, people are happy to live by the sea, why don’t you allow it?" Shizhu replied, "The sea was sealed in the Ming Dynasty, so we can only do as usual." Kangxi was very dissatisfied and said: "The frontier ministers should take the national economy and people’s livelihood as their thoughts. Although the sea is forbidden today, people who trade privately also go to sea to make a living; To be honest, if you are not allowed, it is just for your own convenience. " Shizhu was speechless for a while. In the 24th year of Emperor Kangxi of Qing Dynasty (1685), the imperial court opened four ports for trade: Guangzhou, Ningbo, Zhoushan and Xiamen.However, at that time, there was no distinction between Chinese and foreign trade, and there was no specialized foreign trade firm. In the early days of the switch, when western ships arrived, officials were in a hurry, and foreign ships were often blocked outside the port and could not trade for a long time. In the spring of 1686, the second year of Guangdong Customs switch, the Guangdong government finally found a solution-Wu Xingzuo, Governor of Guangdong and Guangxi, Li Shizhen, Governor of Guangdong, and Yi Ergtu, the supervisor of Guangdong Customs, jointly discussed and divided the national tax into two categories: "residence tax" and "line tax". The "residence tax" is a tax levied on all goods landed in the inland trade of this province, which is collected by the tax department and called "Golden Line"; "Travel tax" is a tax on goods sold by foreign countries and goods traded at sea, which is collected by Guangdong Customs. "Foreign goods line" means "thirteen lines". When it comes to the meaning of "line", it means "line and column", which is "the place where goods live". From then on, foreign goods company 13 became a professional firm engaged in foreign trade, which was managed by the state to prevent free exchanges between Chinese and foreign people. In the twenty-second year of Qianlong (1757), Qianlong made a decree in the Forbidden City: "The port is set in Guangdong, and foreign ships are allowed to dock in Guangdong." The other three ports were closed, and Guangzhou became the foreign trade center of Qing Dynasty. This export painting in Qing Dynasty depicts the scene of local businessmen talking with foreign businessmen. How prosperous is the thirteenth line? The 85-year-old "one-stop trade" has made Guangzhou’s routes to the world increasingly developed. In addition to the routes to the Indian Ocean, Nanyang, Japan and Europe that have been in use in the Ming Dynasty, it has also increased the routes to North America, Oceania and Russia through the Cape of Good Hope.In many places overseas, there are scenes of merchants from various countries shuttling around the "canton" thirteen-line commercial pavilion area and tens of thousands of races on the river, which makes people marvel at the prosperity of Guangzhou at that time. Although according to the regulations of the government, foreign businessmen could not live in Guangzhou at that time, but only in the suburbs or Huangpu Port, every rest day, businessmen or sailors could walk into the city gate and visit the flower pagoda and longevity temple of Haikuang Temple, and they could also visit scenic places such as Baiyun Mountain and Fangcun Flower Land. Guangzhou, a trading port, became the preferred "golden port" for western merchant ships after the opening and closing of the Qing Dynasty. Of course, silk porcelain, tea and homespun were exported, while wool, cotton, metals and spices were imported from abroad. In 1984, British divers found the Dutch merchant ship "Helder Malsen" which sank on the rocks in 1751. When it returned from China, it brought 147 pieces of gold, 239,000 pieces of porcelain in 203 boxes, 687,000 pounds of tea, textiles, lacquerware, sappan wood and thymelaeaceae. By 1986, when part of the sunken ship was salvaged for auction, the guests were dumbfounded by the dazzling array of goods. Qing dynasty export porcelain painted with ocean-going sailboats. In those days, foreign businessmen came to Guangzhou with great enthusiasm. Apart from Russian caravans crossing Siberia to the northern border of China and Portuguese merchant ships trading in Macau, neighboring countries and European and American countries, including the Netherlands, Spain, Britain, France, Sweden, Denmark, Belgium, Prussia, Italy, the United States and Peru, participated in the tribute trade with China.All of them are trading in the 13th Commercial Hall in Guangzhou. In Berlin Coin Museum, Germany, there is a silver coin with the head of Prussian king on the front and a Guangzhou businessman in Qing Dynasty costume on the back. There is a box of tea behind the businessman. This is a commemorative coin made for Prussian merchant ships who sailed to Guangzhou for the first time in the seventeenth year of Qianlong (1753), and it is the only commemorative coin in Europe with the image of Qing Dynasty. Among the foreign ships coming to China, there are also names with Chinese flavor, such as "Guangzhou", "Merchant of China" and "empress of china". This painting for export in Qing Dynasty reflects thirteen lines of street customs. It is worth mentioning that there are canton in many overseas places. For example, Canton in Massachusetts and Canton in Georgia are towns named after Guangzhou, while Canton in northeast Ohio is the largest Guangzhou city in the United States. Since the second half of the 18th century, there have been dozens of foreign merchant ships coming to Guangzhou every year, with more than 80 at the most. By the early 19th century, it had increased to one or two hundred. In 1784, the American merchant ship "empress of china" made its maiden voyage to Guangzhou with leather goods and American ginseng worth 120,000 US dollars. "empress of china" also kept all the naval equipment to prevent pirates from looting. On May 11th, 1785, "empress of china" returned to the United States, causing a sensation all over the country. All the goods on board were snapped up, and Washington, the founding president of the United States, also bought a teapot with a dragon pattern. Line 13 has "Tianzi Nanku"There is also a domineering name for the thirteen lines: "Tianzi Nanku". In the process of accumulating wealth, the court also got huge benefits from Guangzhou. From the first year of Daoguang (1821) to the seventeenth year of Daoguang (1837), more than 1.5 million taels of silver tax were received in Guangzhou every year, all of which were dominated by the royal family. The foreign firm also transported foreign goods such as ivory, enamel, snuff, clocks, glassware, gold and silver for the emperor. In the list of 1738, 88 of the 102 tributes were exotic foreign goods. In 1754, hall of mental cultivation was built in the Forbidden City in Beijing, which needed valuable timber from Nanyang, and Guangdong imported 56,400 Jin for it. In 1708, Kangxi suddenly became seriously ill and drank the red wine prepared by the foreign imperial doctor Rod, and his heartbeat quickly returned to normal. In the future, whenever foreign ships entered Hong Kong, Kangxi asked if there was any wine, and if there was, he asked for it to be transported to Beijing as soon as possible. Soon, the world wines gathered in Guangzhou, and a wine "hotline" was formed between Beijing and Guangzhou. In 1758, in an imperial edict, Qianlong instructed that "foreign clocks and watches, western gold beads, exotic furnishings or fresh utensils should be bought", and that "there is no need to cherish fees". It can be seen that Guangdong Customs, Guangzhou Foreign Firm and the court are inextricably linked, and the thirteenth line has become the only foreign goods supply place that the royal family can rely on, so it is called "Tianzi Nanku". The richest group in China relied on the monopoly privilege of foreign trade, and a number of China tycoons appeared in the 13th line, such as Pan Zhencheng, Wu Bingjian and Lu Guanheng, all of whom were rich, among which Wu Bingjian was the most prominent and became the richest man in the world at that time. Wu Bingjian has 26 million taels of silver,It is equivalent to more than 5 billion yuan today, and its income is half that of the Qing government. His son invests in railways in the United States, and the annual interest alone is more than 200,000 taels of silver. In addition, Shisanhang has also become a bridgehead for cultural exchanges between China and foreign countries. Chinese porcelain, export paintings and folk handicrafts are exported from here, and foreign scientific knowledge, culture and art are also introduced into China from here. Exquisite export products in Qing Dynasty. The picture shows the export porcelain candlestick in Qing Dynasty. The relationship between Shisanhang and the world far exceeds trade. In the history of Shisanhang, there were three big fires, and the last fire completely burned Shisanhang. The first fire was in 1822. A cake shop near Shisanhang caught fire, which affected Shisanhang. The fire burned for two days, and many foreign business halls and foreign firms were burned down. In 1842, the thirteenth line suffered a second fire. In 1856, when the Second Opium War broke out, the British army shelled Guangzhou and burned thirteen lines. All the buildings and goods in the thirteen lines were destroyed in the fire. "The connection between the thirteen lines and the world lies not only in trade. It is the first place where the eastern and western hemispheres blend in all directions in the fields of politics, economy, culture, religion, science and technology, language, art and law. " Lily li, curator of Thirteen Lines Museum, said. Tan Yuanheng, a professor and doctoral supervisor of South China University of Technology, believes that Guangzhou has its own urban pattern, which is the economic pattern naturally formed by commercial trade. From the "Fanfang" in the Middle Ages, the Haizhu Stone Commercial Port in the near ancient times, until the appearance of Guangzhou Thirteen Lines, Guangzhou was well-deserved as the "Millennium Commercial Capital". The formation of the city of Guangzhou,It is similar to Florence, Milan, Venice, Rome and other commercial cities with rich wealth in the west. It is the commercial prosperity since ancient times that created Guangzhou and gave birth to Guangzhou-from the beginning, Guangzhou has the characteristics of a marine and commercial city. Therefore, it is not difficult to understand that Shisanxing appeared in Guangzhou, and it was integrated into the world, becoming the earliest commercial leader with modern colors of China. The 13th Guangzhou Tour also has a positive impact on the development of the world economic system. Wang Yuanlin, director and professor of 13th Line Research Center of Guangzhou University, said that 13th Line has a merchant guarantee system, that is, the merchant guarantees many affairs of foreign merchant ships coming to China, bears many responsibilities such as guarantee, and may not owe foreign debts. Once the hong merchants go bankrupt due to debts owed to foreign merchants, other hong merchants will be responsible for sharing the compensation. "This’ sitting together’ guarantee system later became an important reference for the US banking deposit insurance system." Wang Yuanlin said. According to the Secret Files of Foreign Merchants in Qing Dynasty, an American businessman owed Jardine Matheson Wu Bingjian 72,000 silver dollars, which he was unable to repay. When Wu Bingjian tore up the IOUs, he used "Guangzhou English" in his dialogue with American businessmen. New Mission and New Action: Undertaking the historical mission of making friends with the world. Although the back of Guangzhou’s leap into a trillion-dollar city of foreign trade has disappeared in the long river of history, the legacy left by the thirteenth line-the business spirit of facing the world, being the first, being open and innovative, and striving for perfection-has been engraved in Guangzhou’s genes, and Guangzhou has always been at the forefront of China’s foreign trade exchanges. Two hundred years apart, history once again chose Guangzhou in 1951, in order to strengthen the circulation of urban and rural materials,Guangzhou decided to hold an unprecedented material exchange conference called South China Native Products Exhibition and Exchange Conference. Twelve permanent and semi-permanent exhibition halls have been built in the original site of Thirteen Lines. This modernist architectural complex also laid the foundation for the development of cultural parks in the future. In 1952, "Lingnan Cultural Relics Palace" was established at the site of the South China Native Products Exhibition and Exchange Conference, and became a famous exhibition place for cultural activities at that time. In January 1956, Lingnan Cultural Relics Palace was renamed Guangzhou Cultural Park. From "South China Native Products Exhibition and Exchange Conference" to "Lingnan Cultural Relics Palace" and then to "Guangzhou Cultural Park", the names were inscribed by Ye Jianying. Two hundred years after Thirteen Lines were born, history once again chose Guangzhou as the window for China’s foreign trade exchange. On April 25th, 1957, the first floor of Sino-Soviet Friendship Building in Liuhua Road, Guangzhou was filled with gongs and drums, and the first China Export Commodities Fair (hereinafter referred to as the Canton Fair) opened here! "’Poop-poop’ went through the tunnel and the clothes were blackened." At that time, Li Huan, a 31-year-old Hong Kong buyer, arrived at the meeting on a coal-burning train. Without much care, he excitedly squeezed into the cheering crowd. "I have confidence in the sales of domestic products," he recalled fondly. The original intention of the Canton Fair was to meet the needs of economic construction and develop international trade in exchange for foreign exchange. At that time, New China urgently needed to open a channel to connect with the international market, and use the commodity exhibition as a window to display and trade export commodities. The host city of this exhibition should have a foreign trade foundation and a unique geographical advantage.Looking at China at that time, Guangzhou was the best choice: Guangzhou had a long history of foreign trade and was the only trading port in China under the closed door policy of the feudal dynasty for a long time. In terms of location, Guangdong is close to Hong Kong and Macao, which is the most convenient for Hong Kong businessmen. Only Guangzhou in Guangdong can undertake the historical mission of "making friends with the world". The turnover of the first Canton Fair accounted for 20% of the country’s total foreign exchange income in that year, which opened a channel for new China to communicate with the world in the high-pressure international political environment and suffered from "economic blockade" and "goods embargo", and the abbreviation of "Canton Fair" soon became familiar to the world. Since then, the Canton Fair has been held regularly in spring and autumn every year without interruption. Thousands of China enterprises have successfully entered the international market through the Canton Fair, and their export commodities have also changed from primary products to "made in China" and "made in China", and from offline to online and offline integration … On October 15, 2021, the 130th Canton Fair kicked off. During the 65 years from 1957 to 2021, the Canton Fair moved four times in Guangzhou, and the construction area of the exhibition hall expanded from the initial 18,000 square meters to 1.1 million square meters today. The cumulative export turnover of the Canton Fair exceeded US$ 1.4 trillion, accounting for more than 50% of the national export proportion. It has established trade relations with more than 210 countries and regions around the world, and accumulated about 8.8 million overseas buyers flew across the ocean to participate in the conference. The turnover is far from comparable to that of the thirteen banks in that year. In 2021, the total import and export value of Guangzhou’s foreign trade reached 1,082.59 billion yuan.Become a "trillion city of foreign trade". Through the Canton Fair, "gathering customers from all over the world, selling goods from all over the world and selling goods from all over the world" became a reality. In the export painting of Qing Dynasty, a grocery store on the street of Guangzhou. Canton Fair promotes the safe and smooth operation of the global industrial chain and supply chain. On July 19th, 2021, the State Council announced the list of the first batch of cities to cultivate and build an international consumption center. There are five major cities in China, and Guangzhou is the only non-municipality directly under the Central Government. Guangzhou has tasted the "first soup" of cultivating and building an international consumption center city. It is reported that Guangzhou has started the cultivation and construction of an international consumption center city in an all-round way, and it is planned to basically build an intelligent, fashionable and modern international consumption center city facing the world in about five years, so as to realize the transformation from "selling the world" to "selling and buying the world". In 2016, Guangzhou established the 13th Line Museum in Guangzhou on the site of 13th Line Foreign Commercial Pavilion in Qing Dynasty (in Guangzhou Cultural Park). According to Wang Zhen, deputy director of Guangzhou Thirteen Lines Museum, there are more than 4,800 pieces (sets) of cultural relics in the collection, which show the history of Thirteen Lines by means of "cultural relics+historical documents", sand table and electronic animation. "To some extent, Line 13 has a wonderful connection with the Canton Fair." Ye Nong, a professor at China Institute of Cultural History of Jinan University, said this. Cantonese English is very popular. In the process of "one-stop trade" for a long time, Guangzhou people invented a special language-"Guangzhou English". At that time, the inventor of "Guangzhou English" marked the pronunciation of English words in Cantonese, and gradually formed a distinctive one."Local English". After the opening of Shanghai, "Guangzhou English" spread to Shanghai and became the originator of "Pidgin English". Can you understand "Guangzhou English" Chinese: chin-chin, how do you do, long time my no hab see you. (Please, hello! I haven’t seen you for a long time) Foreigner: l can secure hab long time before time my no have come this shop. (It’s really been a long time, I didn’t come to your shop last time) Chinese: Hi-ya, so, eh! What thing wantchee? Oh, really, what do you want? ) foreigner: oh, some little chow-chow thing. you have got some ginger sweet? Oh, I want something small. Do you have any ginger preserves? ) Chinese: Just Now No Got, L Think Canton Habgot Velly Few That Sutemeet. (Not now, I think there are few such candied fruits in Guangzhou) (Excerpted from Wu Yixiong’s "Guangzhou English" and Chinese-Western Communication before the mid-19th century).The deep contact between the first group of people who opened their eyes to the world and foreigners in China made Thirteen Hong Merchants become the first group of people who opened their eyes to the world in China. During the Opium War, thirteen merchants took the lead in donating money to introduce advanced western technology and upgrade the equipment of Guangdong Navy. Pan Shirong devoted himself to imitating the most advanced steamship in the world at that time; Pan Shicheng hired a US naval officer with a high salary to copy the earliest modern mine in China-"Ship Attack Mine"; Zheng Chongqian was the first Chinese to spread the vaccinia law. The Wu family contributed a lot to the introduction of western medicine into China. The Vaccinium Vaccination Bureau, the first hospital in China, and the Ophthalmology Medical Bureau of Peter Peter Parker also received strong support from the Wu family. It can be said that the thirteen-line merchants were the earliest practitioners of "learning from foreigners to control foreigners", which was 20 years earlier than the Westernization Movement in the late Qing Dynasty. After the end of the "one-stop trade" era, a large number of Guangzhou foreign trade businessmen moved to Shanghai and Hong Kong, forming the first wave of immigration in Shanghai. In the 1950s, Shanghai replaced Guangzhou as the largest trading port in China. What attracted the most attention from Guangdong was no longer goods, but a group of people called "comprador". The original Shanghai foreign firm was "comprador" and "half of it was made by Cantonese people". After arriving in Shanghai, Guangdong Hong merchants bought a large number of properties and real estate, and planned to build a Shanghai version of the "Thirteen Hong Merchants Pavilion" and rent it to foreign businessmen. However, because local officials accepted bribes from British businessmen, Guangdong merchants are nominally property owners of real estate and real estate.However, he was deprived of the right to dispose of real estate and real estate, and was forced to rent it to the British permanently without receiving the rent. Relying on this concession, British businessmen expanded step by step in Shanghai, and finally the Bund was formed in this area. The annotation "line, column also" in "thirteen lines" is "the place where goods live", which is the definition of "line" in ancient books. Guangzhou Shisanhang was a firm specializing in foreign trade in the Qing Dynasty, and it was a monopoly institution designated by the Qing government to specialize in foreign trade. In 1813 and 1837, there happened to be thirteen firms, such as Jardine Matheson of Wu Bingjian, Kwong Lee of Lu Jiguang, Tong Fu of Pan Shaoguang, etc., but the number of the firms varied, ranging from four to more than twenty, and the "thirteen firms" were just the established appellation. The names of banks often change, including Xinglong, Lianxing, Dexing, Zhengxing, Tongxing, Yuanchang, Jinyuan, Yihe and Baoshun. Among them, Pan, Wu, Lu and Ye, the four major merchants, had more property than the national treasury income at that time, and they were truly "extremely rich". According to Wang Zhen, deputy director of the Thirteen Lines Museum in Guangzhou, according to historical records, the Thirteen Lines Site is located in today’s Guangzhou Cultural Park and its surrounding areas, including the China line number and the foreign commercial museum. The China line number is scattered, and some line numbers are outside the Thirteen Lines Street; However, foreign commercial pavilions are relatively concentrated, and the houses are all built facing the Pearl River, like a floating city on the water.

Energy Station: Revealing the Power Exchange System and Driving the New Trend of Electric Vehicles

With the increase in the number of new energy vehicles, the demand for charging and replacing facilities for new energy vehicles has increased simultaneously. Due to the relative shortage of land and power resources in China, we think that with the continuous increase of vehicle ownership,The power exchange mode is expected to be a good supplement to the charging mode, and it has broad medium and long-term development prospects.

Nowadays, the construction and operators of power exchange stations are responsible for the construction and operation of power exchange stations and provide power exchange services to the market. Among them,Power exchange system is the core of power exchange station.

The application of power exchange mode provides an efficient and convenient charging scheme for logistics distribution vehicles. Logistics enterprises can replace batteries at their own distribution sites or partner’s power exchange sites without waiting for charging time, which improves distribution efficiency.
  • ?Travel and tourism field:In tourist attractions or city power exchange stations, visitors can easily change batteries and continue their journey. This not only reduces the charging time of tourist vehicles, but also avoids the embarrassing situation that they can’t continue driving because of insufficient batteries. At the same time, the power exchange mode avoids the trouble of tourists looking for charging piles during the tour and improves the convenience of travel.
  • ?Urban public transport field:Electric buses, electric taxis and other vehicles can replace batteries at bus stops or special power exchange stations, which can quickly restore power and improve operational efficiency. At the same time, the power exchange mode solves the problem of the shortage of charging pile resources in the traditional charging mode, and provides better service for public transportation.

Advantages and disadvantages of power exchange system

The main advantage of the power exchange system is that itEfficiency and convenience.Compared with the traditional charging method, the process of changing power is usually completed in a few minutes, which greatly shortens the charging time of electric vehicles. In addition, the power exchange system can also be standardized, so that different brands and models of electric vehicles can share the same set of power exchange facilities.And the utilization rate and compatibility of facilities are improved.

Answer questions! How can the public respond scientifically to the high incidence of swine flu?

  Xinhua News Agency, Xi ‘an, March 13 (Reporter Lin Juan) Influenza monitoring by China CDC shows that the level of influenza activity has increased in many places in China recently, and influenza A virus is the absolute advantage among the popular influenza viruses. What is swine flu? What’s the difference between flu and common cold? How should I treat the flu? How to scientifically prevent influenza? The reporter interviewed disease control experts and infectious disease experts to answer your questions.

  What is swine flu?

  Yu Pengbo, director of the Institute of Viral Disease Prevention and Control of Shaanxi Provincial Center for Disease Control and Prevention, said that influenza A is the abbreviation of influenza A and an acute respiratory infectious disease caused by influenza A virus infection. Influenza virus can be divided into four types according to its core protein: A, B, C and D. Influenza viruses that are seasonal epidemic in the population are influenza A (subtype A H1N1 and subtype A H3N2) and influenza B (strain Yamagata and strain Victoria).

  Compared with influenza B virus, influenza A virus has many hosts in nature, and it is more prone to mutation or recombination, resulting in its rapid spread among people. Many large-scale outbreaks of influenza in history are related to influenza A virus.

  Influenza patients and recessive infections are the main sources of seasonal influenza infection. Influenza virus is mainly transmitted through air droplets, and can also be directly or indirectly transmitted through oral cavity, nasal cavity, eyes and other mucous membranes. Contact with items contaminated by viruses may also cause infection. It can also spread in the form of aerosol in a crowded, closed or poorly ventilated room.

  What’s the difference between flu and common cold?

  Yu Pengbo introduced that, first of all, the pathogens of the two are different. The flu is caused by influenza virus, and the common cold is caused by rhinovirus and adenovirus. Second, the seasonality is different. Influenza has obvious seasonality (from October to March of the following year in northern China), while the common cold has no obvious seasonality. Third, the symptoms are different. The typical symptoms of influenza are fever, with body temperature as high as 39 to 40 degrees Celsius, accompanied by chills, severe systemic symptoms, headache, muscle pain and fatigue. The common cold generally does not have fever or mild or moderate fever, with nasopharyngeal symptoms as the main symptoms, such as sneezing, runny nose, stuffy nose, sore throat, etc., with mild or no systemic symptoms. Fourth, the harmfulness is different. Generally, the body temperature gradually subsides after 3 to 4 days of influenza onset, and the systemic symptoms improve. However, high-risk groups such as the elderly, children, patients with chronic diseases and pregnant women may be complicated with complications such as pneumonia, otitis media and myocarditis, which may develop into severe illness or even death. Complications of the common cold are rare, and they usually recover in 5 to 7 days.

  How should I treat the flu?

  Ye Feng, chief physician of the Department of Infectious Diseases of the First Affiliated Hospital of Xi ‘an Jiaotong University, said that after symptoms appear, general patients are advised to rest at home and keep the room ventilated. Get enough rest, drink plenty of water, and the diet should be easy to digest and nutritious. Minimize contact with others to avoid infection. The focus of treatment is to relieve flu-like symptoms such as fever and cough, and the patient’s condition changes should be closely observed. Once persistent high fever occurs, accompanied by severe cough, dyspnea, mental change, severe vomiting and diarrhea, you should see a doctor in time.

  Children under 5 years old, the elderly, patients with chronic diseases, pregnant women or obese people are more likely to have serious complications. They should seek medical treatment as soon as possible and use antiviral drugs under the guidance of doctors as soon as possible. Antibiotics and hormones are ineffective against influenza virus.

  It should be noted that not everyone who has the flu must take antiviral drugs. The vast majority of influenza antiviral drugs are prescription drugs, which need to be evaluated by doctors before use. At present, the available antiviral drugs for influenza in China mainly include oseltamivir, zanamivir, palamivir, Abidor and mabaloxavir.

  How to prevent influenza?

  Ye Feng introduced that in daily life, maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. Wash your hands frequently and keep the environment clean and ventilated; Minimize activities in crowded places and avoid contact with patients with respiratory infections; Observe the etiquette when coughing; You should pay attention to rest when you have flu symptoms; Wear a mask when going to public places or seeking medical treatment. In addition, vaccination is the most economical and effective means to prevent influenza. It can be vaccinated one to two months before the peak of influenza epidemic, and it can also be vaccinated when the vaccine is available in the epidemic season.

Online celebrity Da V lied that behind cancer patients: fabricating "selling miserable" people for traffic.

  On March 30th, a blogger named "Yang Kim Jyan" in Weibo released a video "I still can’t figure out why I was diagnosed with liver cancer", which attracted a lot of netizens’ attention. The topic "Why cancer is late when it is discovered" once rushed to the top of the hot search list in Weibo.

  But then everyone found that the video content was not the real experience of the blogger, and the words "this content is purely fictional" were placed at the end of the whole video and appeared for a short time, which caused many people to misunderstand.

  On March 31, the relevant platform imposed a ban on the blogger and suspended advertising revenue. However, the video has been played at least 20 million times before it was taken off the shelf, and its practice of "gaining traffic by consuming cancer patients" has been questioned by many netizens.

  The person in charge of an MCN organization (a company that helps the contracted people to continuously export and realize the content) told the Red Star journalist that some anchors did attract traffic by "selling badly". There is also a special team to help them fabricate "people’s design", "nothing more than attracting more people’s attention in order to realize the traffic."

  On March 31st, Zhu Wei, deputy director of the Communication Law Research Center of China University of Political Science and Law, said in an interview with Red Star that bloggers such as "Yang Kim Jyan" are pursuing the attention or benefits brought by "traffic economy". "In addition to the ban on bloggers, the platform also suggests that the incubation and management institutions behind such bloggers be punished accordingly."

  0one

  Online celebrity bloggers shot nearly 8 minutes of video.

  Claimed that he had liver cancer at the age of 25.

  The word "pure fiction" flashed by.

  On March 30th, Red Star journalists noticed that the video of "Yang Kim Jyan" was nearly 8 minutes long. First of all, he said, "Today is Su Yan, and I want to tell a news that only a few very good friends knew before sending this video." Then he told me that he was diagnosed with liver cancer during his physical examination, and the doctor told me that the chance of cure was not great. In the video, "Yang Kim Jyan" also said many times that he couldn’t understand why he got liver cancer at the age of 25.

  "Yang Kim Jyan" is a blogger with more than 5.5 million fans. After the video was released, the number of plays increased rapidly, with more than 20 million plays on the afternoon of March 30th. Many netizens left messages under the video saying "I hope this is not true" and "I must treat it well".

  ↑ "Yang Kim JYAN" released the video "Liver cancer was detected at the age of 25" on March 30th.

  The Red Star journalist noticed that "Yang Kim Jyan" said in the second half of the video that he had conducted a review and got the results of the review, but when he saw the results, "Yang Kim Jyan" just shook his fist and didn’t say what the results were.

  Many careful netizens noticed a flash at the end of the video. In this picture, "Yang Kim Jyan" means "the content of this video is pure fiction", but this sentence is inconspicuous in the whole picture and is sandwiched in five lines, and the words "pure fiction" do not appear in the whole video.

  ↑ At the end of the video, it is marked "The content of this video is pure fiction", and the display time is very short.

  02

  The blogger apologized after being questioned.

  The platform punishes the suspension of its advertising revenue.

  Previously, the video hinted that he was "suffering from depression."

  Some netizens said that the content of the whole video shooting will cause viewers to misunderstand that they have indeed been diagnosed with liver cancer. Such videos will seriously hurt the feelings of cancer patients and their families. A netizen said: "‘ There is no cancer in the world ’ It is the wish of many people. Maybe some people will never understand the pain of cancer patients and their families, but please ask these people to maintain a little kindness and respect for others. "

  On the afternoon of March 30th, "Yang Kim Jyan" deleted the video of "cancer was found" and issued an apology statement. Its statement said: "I thought of presenting it in the first person way in order to make this video sound a wake-up call for everyone to pay attention to their health. Because the video content needs a physical examination, I also did a full-body physical examination at my own expense. At the end of the video, I told everyone that the video was fictional and it was my negligence in creation. I am sorry for everyone, I know it was wrong. " The statement also mentioned that he will continue to work hard to create videos that correct energy later. "If it is fictional content, I will definitely put it at the beginning (place) of the video, please supervise."

  On the morning of March 31st, Weibo, the official of Sina Weibo community management, announced that during the recent inspection, the station found that the user "Yang Kim Jyan" posted a deductive video describing his feelings after being diagnosed with cancer, but did not mark the content as "fiction" or "deduction" in the obvious position of the video, and only the explanation that "the content of this issue is purely fiction" appeared at the end of the video, which led some netizens to misunderstand it as a real event, which led to public opinion discussion. According to the Weibo Community Convention and other relevant regulations, the station punished the user money "Yang Jyan" by stage silence, forbidding attention and suspending advertising revenue.

  The Red Star journalist noticed that on November 5th last year, "Yang Kim Jyan" had released a video suggesting that he had suffered from depression. "I once wanted to leave, but in the end I got better! I hope you can get better as I do! "

  ↑ "Yang Kim Jyan" released the video content of depression last year.

  Since then, "Yang Kim Jyan" has published several Weibo articles with the related topics of "depression".

  0three

  There was an anchor who took a "vomiting blood photo" and bo sympathized with the goods.

  MCN employees: let bloggers "sell badly" for traffic

  Create a special story "script"

  Unlike "Yang Kim Jyan", which marked "the content is pure fiction" in an inconspicuous place, there were some platform bloggers who directly pretended to be ill and "sold badly" to gain profits.

  According to the police report in Ningbo, Zhejiang Province last November, a man surnamed Zhang made up his illness "selling badly" in Tik Tok, and broadcast live to receive a reward and carry goods. When it was reported and verified, it had illegally made a profit of more than 50,000 yuan, and the man surnamed Zhang defended himself. "I never said that I had cancer, I was just in the late stage of lovesickness."

  In the first half of 2021, a blogger in bilibili issued his own "photos of vomiting blood" one after another, defrauding him to donate more than 40,000 yuan, and finally his account was banned by the platform. In addition, "Sick Yuan" appeared on platforms such as Xiaohongshu before, falsely claiming that he was suffering from a serious disease, so as to bring products such as scar repair stickers and health care products to netizens.

  On March 31 this year, a staff member of an MCN organization told the Red Star journalist that there is fierce competition among various anchors and bloggers with goods. "There will be income if there is traffic. Therefore, when cooperating with some enterprises, if the enterprises agree, they will create some story scripts and shoot some fictional content, many of which are through ‘ Sell badly ’ To attract attention. In order to avoid being held accountable, ‘ will also be marked in the live broadcast or video. Fiction ’ The words, but very vague, or marked in an inconspicuous place. "

  Mr. Xie (pseudonym), the head of an anchor brokerage company in Xi ‘an, told the Red Star journalist that in the past few years, some anchors mainly promoted their own "selling miserable" people to attract attention.

  "First of all, there needs to be conflicts. For example, when you are sick, you must be young, or you are in a beautiful stage of life; Then, with some stories, for example, I am a rural family, working hard in the city, or my partner doesn’t know how to make progress, and she relies on her own work in exchange for sympathy; Then start bringing products into live or released videos to make a profit. "

  Mr. Xie said that these are all specially scripted, and some even use a script on different anchors. In recent two years, a platform has dealt with the shooting of "fake stories", so everyone will also mark the word "fiction" in some inconspicuous places, but if it is not obvious, many fans will not notice it.

  Red Star News reporter saw that on the platform of Weibo, the profile of "Yang Kim Jyan" was "Beauty Red Man". Previously, he released some beauty videos with brand exposure, and some life videos and photos also showed beauty products.

  How to put an end to "selling miserably" fake videos?

  Platform: indefinitely banned or fans cleared.

  On March 28th, the State Council Office held a press conference on the "Qinglang" series of special actions in 2023. In response to the ecological management of short videos, it was pointed out at the meeting that "comprehensively cleaning up short videos that are misdirected and mislead the public by forging scenes, compiling details and fictional experiences" is one of the main contents of this special action.

  For this kind of situation, Fu Jian, director of Henan Zejin Law Firm, believes that the authenticity of network information is difficult to guarantee in the media era, and many online celebrity bloggers sacrifice the authenticity of their published information in order to increase traffic. Online celebrity uploaded a short video saying that he was diagnosed with liver cancer during his physical examination. He filmed and uploaded a very authentic video, and put the statement that "this content is pure fiction" in an inconspicuous position in the last two seconds of the video, which led to misunderstanding by most people, causing a wide range of influence and deceiving the public’s feelings.

  Fu Jian said that many laws and regulations, such as the Cyber Security Law of the People’s Republic of China, the measures for the management of Internet information services, and the regulations on the ecological governance of network information content, all emphasize that information such as short videos published online should abide by public order and good customs and uphold the principle of good faith. Among them, Articles 6 and 7 of the Regulations on Ecological Governance of Network Information Content stipulate that network information producers shall not publish illegal information and shall resist bad information. Short video posing and deceiving the public’s feelings are bad information, and serious ones may be suspected of breaking the law. The network information content service platform can take measures such as warning and rectification, limiting functions, suspending updates, and sealing titles to resist the spread of this bad video.

  The Xiaohongshu platform said that it will resolutely ban the "self-media" of counterfeiting official institutions, news media and specific personnel, including account name counterfeiting, information content counterfeiting and professional qualification counterfeiting; Comprehensively rectify the illegal profit-making behavior of "self-media", including smashing hot spots to attract powder and drain, creating hot spots to generate traffic, and using vulnerable groups to realize traffic.

  Lawyer Chen Hao, director of Shaanxi Dezun Law Firm, told the Red Star journalist that if online celebrity defrauded money by fictional facts or concealing the truth in the video, and the amount reached the filing standard, it should be suspected of fraud. If online celebrity only makes up facts to shoot videos for the purpose of attracting attention, gaining attention and defrauding traffic, it belongs to the category of moral evaluation and should be handled by video platforms or regulatory agencies.

  "Recently, the Internet Information Office has been comprehensively cleaning up short videos that are poorly directed and mislead the public by forging scenes, compiling details and fictional experiences. I believe that this phenomenon will become less and less through the guidance and supervision of relevant departments. "

  Red Star journalists found that, except for the Weibo platform, "Yang Kim Jyan" also had accounts with the same name on other short video platforms, and all of them were banned on March 31st.

  In addition, Red Star journalists noticed that many platforms have also released governance measures for fictional content.

  On March 30th, Tik Tok announced that when creators create and publish fictional content through plot deduction, they should clearly mark the relevant video interpretation in a prominent position and form, and the copywriting includes but is not limited to "fictional/deductive works for entertainment only". If the work is not marked as "deduction" or "fiction", causing misunderstanding among the public and the news media and becoming "false information", the platform will strictly deal with it, and the publishing account will be completely banned for 30 days to indefinitely banned depending on the circumstances.

  On March 31st, Aauto Quicker Science and Technology announced that it would impose penalties such as clearing fans, erasing fans, and limiting the growth of fans for the acts of counterfeiting party and government organs, news media organizations and parties involved in public opinion events.

  0five

  It’s all the temptation of traffic?

  Expert advice: link the responsibility to MCN organization.

  On March 31st, Zhu Wei, deputy director of Communication Law Research Center of China University of Political Science and Law, said in an interview with Red Star journalist that the main source of this situation lies in the temptation of "flow economy".

  "They get sympathy in this way, and sympathy can be transformed into traffic, traffic can be transformed into attention, and finally into commercial interests."

  Zhu Wei said that in the past, more content of "pretending to be terminally ill" was very direct false charity and fraudulent donation, but the "terminally ill video" made by "Yang Kim Jyan" was artificially created to directly gain traffic. The role of people’s design is to obtain stable traffic and accurate fans in their vertical fields, so as to improve their ability to carry goods and attract fans to reward them. These are a set of rings.

  Zhu Wei agreed with the relevant measures taken by this platform, but he also reminded that it is necessary to consider whether such bloggers’ front-end accounts are banned and whether background users or registrants should also be included in the "blacklist". Otherwise, he may turn himself around and open the number somewhere else. In addition, we should pay attention to the MCN organization behind online celebrity, that is, the relevant resource management team. Generally, such accounts are supported and managed by the MCN organization, and the responsibility should be related to the MCN organization and other related accounts of this kind of MCN.

  "MCN has hatched a lot of accounts like this now. Many of the fake people are created and recommended by MCN behind it, and it is also the traffic that MCN pushes to this account."

The risk assessment plan should be issued and implemented by the main person in charge of the unit (or its authorized person in charge)..

If there is too little relevant information, so that the risk assessmentworkWhen it is difficult to carry out, some risk reduction measures can be introduced in a targeted manner to reduce the risk of some key links and simplify the evaluation scheme.

6.2 Evaluation stage  

Carry out analysis and evaluation according to the risk assessment plan. Through hazard identification and analysis, field investigation, and qualitative and quantitative evaluation of hazard factors.

6.2.1 Identification and analysis of dangerous and harmful factors. Identify hazards and various dangerous and harmful factors, identify risks, and analyze and judge the degree of safety risks.

eight Risk grade determination

From high to low, the risk level of experimental safety is divided into major risk (level 1), major risk (level 2), general risk (level 3) andLow risk (level 4) four levels.

Level 1 (red): significant risk. It is extremely dangerous and cannot be carried out.In the experiment, control measures should be supplemented immediately in order to reduce the risk level, and regular inspection, measurement and evaluation should be carried out;

Level 2 (orange): greater risk. High risk, immediate rectification, supplementary control measures, regular inspection, measurement and evaluation;

Level 3 (yellow): general risk. Significant danger, need to be rectified, establish goals, establish operating procedures, and strengthen training and communication;

Level 4 (blue): low risk.lowerDanger, need to pay attention to, improve the control measures in time.

The conclusions obtained by different risk analysis and evaluation methods may be different, so the one with the highest risk level should be selected as the risk level of the project.

Experiments and experimental projects adopt a safety risk classification and classification management mechanism. Effective safety prevention and control measures and emergency plans should be formulated and strictly implemented for experiments and experimental projects with risk level above level 3, and experiments can be carried out only after being examined and confirmed by the unit, and relevant materials should be filed.

According to the relevant national and industrial regulations, norms and standards, the classification of experiments and experimental projects and the division of risk levels are adjusted in a timely manner (see AnnexC)。

 Risk assessment method

 According to the characteristics of experiments and experimental projects, comprehensive analysis, qualitative and quantitative evaluation are generally carried out by using hazard analysis method of working conditions, pre-hazard analysis method, analogy method and checklist analysis method.

(1)Hazard analysis method (LEC)

Hazard analysis method for working conditions (GrahamGinny method is a semi-quantitative risk assessment method for workers working in occupational hazardous environment. The evaluation principle is: the quantitative risk value of operating conditions (D) depends on three factors, (one) the possibility of an accident (L); (2) Frequency of exposure of workers to dangerous working environment (E); (three) The severity of possible consequences in the event of an accident (C)。 Represented by a simplified formula is:D=L×E×C

(2) Pre-hazard analysisway

Pre-hazard analysis (PHA) is a system safety analysis method that makes a macro and general analysis of various risk factors (categories and distributions), occurrence conditions and possible consequences of accidents in the system before an activity (such as an experiment). Its purpose is to find the potential risk factors of the system at an early stage, determine the risk level of the system, and put forward corresponding preventive measures to prevent these risk factors from developing into accidents and avoid thoughtlessness.The losses caused are qualitative evaluation. That is to say, discuss, analyze and determine the dangerous and harmful factors existing in the system, their triggering conditions and phenomena, the causes and events that caused the accident, the accident types, the accident consequences and the danger level, and put forward the safety precautions that should be taken.

(one) Pre-hazard analysis step

 Fully investigate the purpose, process, operating conditions and surrounding environment of the experiment;

 Collect past experience and accidents in similar experiments, judge whether similar situations will occur in the objects to be analyzed, and find out the dangers that can cause material losses and personal injuries;

 Determine the hazard source according to experience, technical diagnosis and other methods;

 Identify the conditions of dangerous transformation and study the trigger conditions of dangerous factors transforming into accidents;

 Carry out risk classification, determine the degree of risk, and find out the dangerous sources that should be controlled emphatically;

 Formulate risk prevention measures.

(2) risk classification

PHAThe result of the analysis is expressed by the risk grade. Danger can be divided into four grades, as shown in table.five.

(four) analysis summary

Through the pre-risk assessment and analysis, the main risks and risk grades of experiments or experimental projects are obtained.

For all kinds of possible dangers and harmful factors, preliminary preventive countermeasures and measures are put forward one by one in the risk pre-analysis table.

(3) analogy method

Through the safety investigation of the same or similar projects as the experimental projects to be evaluated, and the analysis of relevant experimental documents and technical data, it is proposed to evaluate the types and degree of hazards and harmful factors of the experimental projects by analogy, assess the possible hazards and harmful factors, and predict the control effect of the proposed safety protection measures.

(4) Checklist analysis method

According to the national laws, regulations, technical specifications and standards related to occupational safety and health, as well as operating procedures and production safety accident cases, through detailed analysis and research on the experimental items to be evaluated, the inspection units, parts, items, contents and requirements are listed, and a table is compiled to check the compliance one by one to determine the safety problems, defects and potential hazards of the experimental items to be evaluated.

February 5, 2020

No doubt! This year’s National Day file is the most neglected good movie!


Special feature of 1905 film network "The film arrangement is too low". After the animated film was released, many netizens expressed such feelings. 


Abominable, the first original animated film of Oriental DreamWorks, was jointly created by Oriental DreamWorks and American DreamWorks Animation.


Under the upsurge of three major gift films sweeping the National Day archives, the topics and popularity of the films are slightly insufficient. As of October 5, the film’s five-day box office reached more than 70 million, which was not as good as expected.


Despite the poor box office, the word-of-mouth achievements of Cat’s Eye 9.4, Taobao Film 9.1 and Douban 7.4 are quite eye-catching, and the performance of overseas markets is in sharp contrast with that of China. After landing in North America on September 27th, the film won the first weekend box office title in North America. The freshness of rotten tomatoes is 80%, and the popcorn index is 96%. These data are enough to show the quality and level of this Chinese-foreign co-production animation.


Is Abominable the most underrated work in this year’s National Day archives? In addition to box office and word of mouth, the Chinese-foreign co-production mode it presents and its influence on the local animation film industry in China are actually the most important aspects to be discussed.


Chinese and foreign co-produced animated films are not popular?


 In 2016, "Kung Fu Panda 3" created a box office of 1 billion in mainland China, occupying the top spot in China animated film box office for three years, and it was not until this summer that it was won by "Nezha".


The emergence of Kung Fu Panda 3 has led to the rise of Chinese and foreign co-production animation, with a large number, but the box office and quality have been "sluggish". Among the top ten Chinese and foreign co-produced animated films at the box office, only three have exceeded 100 million.


Although Kung Fu Panda 3′ s billion-dollar scale far exceeds other rivals, its success largely depends on the accumulation of IP fans of the previous two series.


Looking at the evaluation, half of the works on the list are below the passing line on the Douban platform.


Therefore, if we compare these ten co-produced animated films horizontally, the achievements of Abominable are not bad now.


Before "Abominable", this year’s co-production animation was also released. The film was originally scheduled to be released last year and was postponed until July this year. Another co-production animation has also changed its schedule four times, and now it has been postponed to October 13th.


It can be inferred from the achievements of Future Machine City that the finished product of Ugly Doll, which was also co-produced by Alibaba Pictures, is not expected to be very satisfactory.


The douban scores of "Future Machine City" and "Ugly Doll" are also below 6.

 

What’s the problem?

 

China only invested capital and did not participate in the production; The Chinese team’s participation in content creation is very shallow; Inaccurate audience positioning; The story is routine and younger; Problems in the cooperation mechanism are the reasons why these co-produced animations have not been favored by the market and the audience.

 

By chasing light animation and Warner Bros. together, it is a more successful co-production animation in recent years.


The light-chasing animation, which has always focused on creating family fun, has been created from China fairy tales after successive encounters and failures of other works.


Warner Bros. put forward targeted opinions on stories, editing, personnel design and commercial selling points during the production process. For example, the role of "puppy" was added to strengthen the comedy elements, and it was especially suggested to design a wonderful bridge of Little Fox Fairy.


Little fox fairy stills

 

The success of "White Snake" benefits from the continuous improvement of Chinese creation in the co-production mechanism. The story is also different from many previous co-production animations. It is not the traditional "general mobilization" adventure family fun, but draws nutrition from China fairy tales and adapts it.


The story of Abominable takes place in present-day China.

 

"Abominable" still chooses the type of family fun, and puts the main story world in the present China, and all the contents should be original.

 

So, how did the animation produced by Fang Dongfang DreamWorks and American DreamWorks create a mutually acceptable China story? In the interview with the main creator, we not only got the answer, but also found that this co-production is closer and deeper than many previous co-produced animated films.


Is there a new atmosphere in the production mode of Abominable?


"Abominable" tells the story of Xiao Yi, a little girl from China, and her friends, A Jun and pengpeng, crossing the motherland for 3,000 kilometers and escorting the snowman "Da Mao" back to his hometown of Mount Everest to reunite with his family.


According to Zhou Peiling, producer and chief creative officer of Oriental DreamWorks, the preparation of the film began in 2012, and the strategic decision-making and specific creation were discussed and decided by both teams.

 

"The whole artistic creation team is basically in Shanghai, and the post-production is mainly in the United States," Zhou Peiling revealed. The only challenge is the time difference. "Today, people here finished and handed it over to people on the other side of the world, so we joked that someone was working on this film for 24 hours, which turned the disadvantage into an advantage."

 

At the same time, Zhou Peiling will also hold regular weekly meetings with American executives and behind-the-scenes personnel to exchange ideas and listen to them, and then complete the production step by step through repeated revisions.


Producer Zhou peiling

 

The film mainly expresses the theme of returning to the family. jill culton, the director and screenwriter, said frankly that "China culture emphasizes the importance of family more than American culture". Therefore, along with the main plot of the snowman going home, they also set up the auxiliary line of the relationship between Xiaoyi and his mother and grandmother from estrangement to bridging, trying to make more China audiences feel empathy and substitution.


Co-director jill culton and Todd Vildman

 

In addition to the balanced transmission of values, compared with many previous co-productions of animation, the localization of "Abominable" is indeed more steady and steady.

 

Although the traditional "adventure" narrative mode is adopted like many family animation, the film is integrated with the unique scenery of China, such as Qiandao Lake, Huangshan Mountain, rape field, Leshan Giant Buddha, etc. These magnificent mountains and rivers have not been reduced to simple background boards or postcards, but have become story scenes to promote the effective progress of the film.


"When I started writing the script, I had a map of China in front of me. The story originated in Shanghai and the final destination was in Himalaya. The distance between the two places was 3,000 kilometers, so I was looking for scenic spots in this distance." jill culton told us that due to the length of the film, I originally wanted to put three or four more scenic spots, including Rainbow Beach and Blue Waterfall.


In addition, she and her team also insisted on not letting go of world-famous China monuments such as the Great Wall, "because everyone knows the Great Wall, but not everyone knows Leshan Giant Buddha."


Leshan Giant Buddha is an important scene in Abominable.

 

In order to create a more authentic "China flavor", Oriental DreamWorks provided more input and support in details, including the street environment of Shanghai, the overall appearance of residential buildings, Chinese’s food culture, table manners and so on, from which the Hollywood production team also got a lot of inspiration.

 

As Carlton said, "In the previous version, everyone threw away metal cans on the road, but Oriental DreamWorks told us that there was no such rubbish, so we deleted all these metal cans."


Chinese consultant directorShuhuan

 

The screenwriter Shu Huan is the Chinese consultant director of the film. He joined the team when the film was about 70% completed. On the one hand, his job was to adjust the localization details.


He suggested adding billboards unique to China, such as "cram school for college entrance examination", and adding food landscapes with China characteristics, such as Shaanxi snacks and Shaxian snacks, "to make the whole story more like the present China".


In the role design, both teams have also made great efforts. Co-director Todd Vildman said that in order to make the character of Grandma more authentic, China has given many suggestions.

 

"Grandma is very nagging. Xiaoyi doesn’t want to listen. Will she close the door or keep it in front of her, or how much? How much is this? These are all to be discussed together." Producer Zhou Peiling also mentioned such creative details to us about the display of characters’ psychology and behavior.


Not only in the content production level, the film also launched a Mandarin version for China audiences, with Zifeng Zhang, Chen Feiyu, Cai Ming, Wan Qian, etc. as dubbing, and Shu Huan was also responsible for dubbing and directing. This dubbed version of Mandarin will also land in the North American cinema, which is the first time in the North American film market.

"Many expressions in the English version are American, but the audience in China will know at a glance that this is not Chinese’s way of speaking." Shu Huan revealed that in order to conform to Chinese’s communication style and expression habits, he helped to adjust many Chinese dialogues to make them more grounded. However, it is also a pity that the film did not specifically change the mouth shape of the characters for the Chinese version.


Four voice actors

 

It can be seen that from the upstream to the downstream, from the plot, the theme, the details of the scene, the character design and the dubbing release, Abominable tries to be close to the local reality of China and meet the needs of China audiences.

 

"China audiences know more and more about movies now," said Zhou Peiling. The reason why many Chinese-foreign animated films have failed is that the market positioning is unclear and the stories are mechanically copied. "Maybe it was only aimed at overseas markets at first, and suddenly it was necessary to join the characters and plots related to China in the China market, which is very unnatural and unsmooth."


The key to the success of Chinese and foreign co-productions lies in finding a universal story with cultural value, highlighting the elements of China, bringing forth the new, and achieving a win-win situation in an effective cooperation mechanism.

 

Both director Carlton and director Shu Huan emphasized that Abominable is not a Hollywood story, but a story suitable for the whole world, and that the China market is not the whole story. The film should not only show the beauty of China culture, but also start from China, aim at the global market and finally go to the world.


What does co-production bring to China native animation?


Looking to the future, there are a large number of Chinese and foreign co-produced animated films on the road. Oriental DreamWorks and American DreamWorks Animation will jointly launch the "Oriental Dream Trilogy": "Abominable" is the first one; The second "Running to the Moon" will be completed next summer and is scheduled to be released in autumn. The third part is the Monkey King, which was developed by Stephen Chow, and it is also in the preparatory stage.

 

In addition, the Legend of the Erect Elephant (China, New Zealand), Animal Secret Service (China, France) and Dragon Keeper (China, Spain) will also appear one after another.

"Use our script story, Hollywood production management experience and excellent animation technicians from all over the world". In Shu Huan’s view, such a global production system can be the main creative direction of China animated films in the future. "Let’s work together. After coming out, 80% is not good, 10% is good, but 10% is explosive, so every little makes a mickle."

 

With the increasing number of co-produced animated films, we have reason to believe that the mode of co-production will be deepened, the quality of animation will be more mature, and the continuous accumulation of co-production experience will also benefit the creation and development of local animation in China.


Chinese and foreign co-production animation to be released in the future


Nezha, White Snake: The Origin, etc. are all born out of China’s fairy tale system. At present, adventure family fun is more in line with the mainstream of world animation films, but the quality of this type of animation independently produced by China still needs to be improved.

 

The appearance of "Abominable" is not only a co-production animation in the future, but also provides corresponding reference for the creation of domestic animated family movies.


Zhou Peiling said that the benefits of co-production can help local animation filmmakers in China learn foreign production methods, story content and animation technology, and also help China’s animation industry gradually realize industrialization and scale, and further expand the international market.

 

Looking forward to the future, China native animation can become the earliest and fastest film genre among all films in China, as predicted by Shu Huan.
