　　"Why do children catch a cold as soon as they go to kindergarten?" "My child is a new junior one, and he has repeated respiratory infections from time to time, which has an impact on his study and life. How to enhance his immunity?" It’s the school season again, and children who get sick as soon as they go to school begin to make their parents nervous again. When the temperature changes suddenly every year, the number of small patients in the pediatric clinic of the hospital increases.

　　Experts from the First Hospital of Changsha City give advice to parents on how to prevent recurrent respiratory infections in autumn and let children spend their school life healthily.

　　A Why can’t a child catch a cold and root it?

　　Xiaolong, who has just been in kindergarten for a few months, is a lively and active child. He looks dignified and sturdy, but his mother always sighs. It turns out that after going to kindergarten, Xiaolong will "catch a cold" every once in a while, coughing, runny nose, etc., and sometimes he has a fever and even pneumonia twice. Xiaolong’s mother said helplessly that because she often went to the hospital, doctors and nurses in the hospital pediatrics became "familiar faces".

　　Xiaolong takes some oral drugs or fluids in the hospital for a few days at a time, and he will get well soon, but he always feels that he can’t cut off his roots. Because he is often sick, he has to ask for leave from the kindergarten teacher. Xiaolong’s mother said worriedly, "When I was born, I heard from the older generation that when the child is older, my body will be better after I was 3 years old. How can I get sick when I go to kindergarten now, and I run to the hospital one after another, worrying about the side effects of drugs, no matter how worried he is about the aggravation of symptoms or even pneumonia?"

　　Mei Mei, a new junior high school student, had a general physique when he was a child. With the aggravation of study tasks, he studied longer and longer every day. Sometimes he did his homework until late and had symptoms of respiratory infection from time to time. Mei Mei’s parents want to enhance her immunity. Some people say that it is good to drink oral liquid, while others say that Chinese patent medicine is good. Mei Mei’s mother doesn’t know whether her child can take immunomodulators, which is very tangled.

　　B The diagnostic criteria of recurrent respiratory tract infection are different at different ages.

　　What exactly is recurrent respiratory infection? What are the causes of recurrent respiratory infections? How should parents and children treat and prevent it?

　　According to the chief physician Wang Xiangyun, director of pediatrics department of Changsha First Hospital, respiratory tract infection is the most common disease among children. According to statistics, every child in developing countries suffers from 4.2 ~ 8.7 respiratory tract infections every year, most of which are upper respiratory tract infections, and the incidence of pneumonia is 10 times per 100 children every year. Respiratory tract infection is divided into upper respiratory tract infection and lower respiratory tract infection. Upper respiratory tract infection is a general term for inflammation of nasal cavity, pharynx or larynx, and it is also commonly diagnosed with terms such as cold, rhinitis, pharyngitis, nasopharyngitis and tonsillitis, which is referred to as "upper sensation" for short. Lower respiratory tract infection refers to tracheobronchitis and pneumonia. The onset is mostly acute, and the only mild symptoms are nasal symptoms, such as runny nose, stuffy nose, sneezing, tears and throat discomfort. If the infection involves the nasopharynx, there are often fever, sore throat, tonsillitis, congestion and hyperplasia of lymphatic tissue in the posterior pharyngeal wall, and sometimes lymphadenopathy. There are also some manifestations of vomiting and diarrhea, which are more common in infants and children, and are clinically called "gastrointestinal cold". In severe cases, there may be persistent high fever, frequent cough, shortness of breath, poor mental health, and severe systemic symptoms.

　　Recurrent respiratory tract infection means that the frequency of respiratory tract infection is too frequent in one year, exceeding a certain range. Different ages have different diagnostic criteria, which can be divided into repeated upper respiratory tract infections and repeated lower respiratory tract infections. Repeated upper respiratory tract infection refers to the infection of infants under two years old ≥ Seven times a year, children aged 2-5 years old were infected with ≥ Six times a year, children aged 5-14 were infected with ≥ 5 times/year; Repeated lower respiratory tract infections include repeated tracheobronchitis and repeated pneumonia. Repeated tracheobronchitis refers to the infection of infants under 2 years old ≥ Three times a year, children aged 2-5 were infected with ≥ Twice a year, children aged 5-14 were infected with ≥ 2 times per year; Repeated pneumonia, regardless of age, as long as it is infected ≥ It can be diagnosed twice a year. The interval between two infections is at least 7 days.

　　C blindly pursuing cough relieving effect aggravates the condition.

　　Wang Xiangyun said that there are many reasons for recurrent respiratory infections, including the following aspects.

　　Immature or low immune function: children are in the period of growth and development, and their immune function is obviously different from that of adults. Most of them are immature or low, even at different ages. For example, the content of immunoglobulin IgA is almost zero at birth, and it only approaches the adult level when it is 11 ~ 12 years old. Among them, secretory IgA is the main immunoglobulin in respiratory secretions, which plays an important role in the first line of anti-infection defense, so children are more prone to respiratory infections.

　　Improper nursing: After suffering from respiratory infection, many parents are worried that it is caused by catching cold, knowing that the weather is hot, or letting their children wear more clothes, resulting in high fever. Wipe the whole body with alcohol after fever, which may lead to alcoholism or allergies; Some parents blindly pursue the effect of relieving cough, but use antitussive drugs, which leads to sputum secretion not being discharged, but aggravates the condition.

　　Admission to nursery institutions, initial stage of enrollment and environmental factors: nursery institutions and schools are a public environment, and children are not used to school just now, so they can’t adapt to the changes of the environment well, and there are many children. When one person catches a cold, other children don’t know how to prevent themselves, and they are in close contact with each other, which is easy to cross-infect. The northern part of China is in the cold and changeable winter and spring season, while the southern part is more likely to cause respiratory tract infections in the rainy season with high humidity in summer and autumn. At the same time, air pollution, passive smoking and other environmental factors can lead to repeated respiratory infections.

　　Unbalanced nutrition: Some children are partial to food, picky eaters and anorexia, which leads to unbalanced nutrition, and they are more prone to respiratory infections than other children.

　　Chronic focus and basic diseases: Some children are more prone to recurrent respiratory infections than normal children because of chronic focus such as rhinitis, sinusitis and chronic tonsillitis, and basic diseases such as congenital immunodeficiency.

　　D treating virus-infected people without abusing antibiotics.

　　The purpose of clinical treatment is to reduce the number of respiratory tract infections.

　　The first is to find the cause and treat the underlying diseases. The most common pathogenic factor of recurrent upper respiratory tract infection in children is pathogen invasion, and the most common are viruses, bacteria and atypical pathogenic microorganisms. Anti-infection treatment for pathogens should not abuse antibiotics for highly suspected virus-infected people, and at the same time strengthen the treatment of basic diseases.

　　Secondly, immunomodulator therapy can be performed. The use of immunomodulators can enhance the immune function of respiratory tract, effectively reduce the frequency of recurrent respiratory tract infections and the use of antibacterial drugs.

　　Third, we must do symptomatic treatment. According to different age and illness, we should correctly choose expectorant, antiasthmatic, antitussive and other drugs, atomization therapy, lung posture drainage and lung physical therapy.

　　In addition, vaccination can be carried out reasonably; Strengthen nutrition, reasonable diet, supplement trace elements and vitamins; Arrange study and life reasonably, adjust the schedule of work and rest, pay attention to the combination of work and rest, not be overtired, and take appropriate outdoor activities and exercise to enhance physical fitness; Avoid passive smoking and odor stimulation, and keep the indoor air fresh.

　　These tests are needed to identify recurrent respiratory infections.

　　Detection of pathogenic microorganisms: it is suggested to actively improve the joint detection of pathogens to determine what kind of pathogen infection it is. For example, anti-streptolysin O can be checked by blood sampling, which is the most common bacterium that causes tonsil suppuration; Nasopharyngeal swab examination of adenovirus and influenza virus antigen further clarified the cause of respiratory tract infection.

　　Otolaryngology examination: Some congenital developmental abnormalities and acute and chronic otorhinolaryngology infection foci such as adenoid hypertrophy and allergic rhinitis can be found directly through preliminary otolaryngology examination or nasopharyngeal laryngoscope.

　　Determination of immune function: primary and secondary immunodeficiency diseases can be found through detection of humoral immune function and cellular immune function. For example, selective IgA deficiency can lead to repeated respiratory infections.

　　Chest X-ray, lung CT and airway and vascular reconstruction: It can effectively find out the location of lung lesions, whether there are abnormal airway and lung development, airway stenosis, bronchiectasis, vascular compression and so on.

　　Bronchoscopy: The foreign body in the airway, airway obstruction and external tracheal compression, airway dysplasia and bronchiectasis can be diagnosed directly under the microscope.

　　Color Doppler echocardiography can provide diagnostic reference for recurrent respiratory tract infection caused by congenital heart disease.

　　Special examination: for example, if you suspect that you have primary ciliary dyskinesia, which leads to repeated cough and expectoration, you can perform respiratory mucosa biopsy to observe ciliary structure and function.

　　What kinds of immunomodulators can be used in children with recurrent respiratory tract infections and what are their contraindications?

　　First, immune system products

　　1. Thymosin: It can be used for the treatment of repeated respiratory tract infections caused by various primary or secondary T-lymphocyte deficiency diseases, and it is forbidden for allergic people.

　　2. Poly-myocyte: used for adjuvant treatment such as recurrent respiratory tract infections, and it is forbidden for allergic people.

　　Second, the chemical synthesis agent

　　2. Cimetidine: used as adjuvant therapy for allergic diseases, some refractory autoimmune diseases, recurrent respiratory infections, oral ulcers, etc. It is forbidden to use with central anticholinergic drugs at the same time, and it is forbidden to patients with severe heart and respiratory diseases, liver and renal insufficiency and organic encephalopathy. It is not recommended for children under 3 years old.

　　Iii. Biological agents

　　1. Bestin: used for the treatment of children’s recurrent respiratory infections and the immune regulation of abnormal diseases. It is not recommended for children with primary phagocytosis or humoral immune deficiency and infants under 1 year old.

　　2. Pantotrichum: It is suitable for the prevention and adjuvant treatment of recurrent respiratory infections, acute respiratory infections and allergic diseases. Allergic to pantothenic protein, autoimmune diseases (caused by antigen-antibody complex related to bacterial infection),

　　3. Transfer factor: it is suitable for adjuvant treatment of recurrent respiratory tract infections, infectious diseases, allergic diseases and autoimmune diseases. Allergy is forbidden.

　　4. BCG polysaccharide nucleic acid: used for preventing and treating recurrent respiratory tract infections, bronchial asthma, recurrent eczema, urticaria and other diseases. It is forbidden for people who are allergic to this preparation, patients with tuberculosis infection, other acute infectious diseases (such as measles, whooping cough, pneumonia, etc.) and children with acute infection.

　　5. Intravenous injection of human immunoglobulin (IVIG): In addition to primary and partial secondary immunodeficiency diseases, it can be used for some diseases related to autoimmune response such as premature delivery infection and intractable epilepsy, and plays an immunomodulatory role. It is forbidden to those who are allergic to IVIG or have other severe allergic history, and those who have selective IgA deficiency of anti-IgA antibody.

　　Iv. immunomodulators derived from plant medicines

　　1. Yupingfeng Granule: Allergic diseases such as allergic rhinitis, allergic cough, bronchial asthma, atopic eczema and chronic urticaria in children. In addition, it can be used as an immunomodulator for children with autoimmune diseases with local and systemic secondary immune dysfunction caused by long-term inhalation or oral corticosteroids. Use with caution during acute infection and fever.

　　2. Fuganlin oral liquid: repeated respiratory infections, cough variant asthma, and viral respiratory infections secondary to treatment with immunosuppressants. This medicine has no special contraindication.

　 　 　 　 Heavy! Against the background that the US keeps escalating the Sino-US trade friction despite its opposition, the Press Office in the State Council, China today released a white paper entitled "Facts about Sino-US Trade Friction and China’s Position". This nearly 40,000-word document clarified the key facts in Sino-US economic and trade with detailed data and cases, strongly refuted a series of untenable arguments of the US government, and fully expounded China’s position and attitude. On Sino-US economic and trade frictions, the white paper puts forward 13 authoritative conclusions!

Conclusion 1. The "American Loss Theory" is untenable.

Since the establishment of diplomatic relations between China and the United States, bilateral economic and trade relations have continued to develop, and cooperation in trade and investment has achieved fruitful results, achieving complementary advantages and mutual benefit. China has benefited a lot from it, and the United States has also gained extensive and huge economic benefits from it, sharing the opportunities and achievements brought by the development of China.

On the whole, Sino-US economic and trade cooperation is a win-win relationship, not a zero-sum game. American enterprises and nationals have benefited from it, and the "American loss theory" claimed by some Americans is untenable.

Second, it is unfair to blame China for the imbalance of trade in goods between China and the United States.

The imbalance of trade in goods between China and the United States is more a natural result of the independent choice of the market under the American economic structure and the existing comparative advantage pattern. To solve this problem, both sides need to make joint efforts to carry out structural adjustment. It is unfair and unreasonable for the United States to ignore many factors that affect Sino-US economic and trade relations, unilaterally emphasize the imbalance of trade in goods between the two countries, and blame China.

Third, the so-called "fair trade" in the United States will cause a wider range of unfairness

The so-called "fair trade" emphasized by the current American government is not based on international rules, but on the premise of "American priority" and aims at safeguarding America’s own interests.

The "fair trade" and "reciprocal opening" advocated by the United States deny the objective differences in the development stages, resource endowments and advantageous industries of various countries, and ignore the development rights of developing countries, which will inevitably have an impact on the economies and industries of developing countries, resulting in a wider range of unfairness, and ultimately will not be conducive to American enterprises to expand the international market and share the development opportunities of developing countries.

The so-called "compulsory technology transfer" in China is a complete distortion of the facts.

Since China’s reform and opening-up, in order to expand emerging markets, save production expenses, realize economies of scale and extend the time of technology profit, foreign enterprises have taken the initiative to establish cooperative partnership with China enterprises, signed contracts and transferred their production capacity and orders to China, which is entirely a voluntary behavior of enterprises based on commercial interests. We should not distort the original voluntary trading activities of both parties into compulsory technology transfer because of the technological progress of enterprises in China, which is neither in line with historical facts nor a betrayal of the spirit of contract.

The U.S. government calls the voluntary cooperation of foreign-invested enterprises to establish partnership with China enterprises, transfer or license their technology and jointly obtain commercial returns in the China market "compulsory technology transfer", which is a complete distortion of the facts.

Conclusion 5. The accusation of the United States against intellectual property protection in China is contrary to the facts.

China has a clear and firm attitude towards the protection of intellectual property rights, and has continuously strengthened protection at the legislative, law enforcement and judicial levels, and achieved remarkable results. The recent accusation of the US government against China’s intellectual property protection is contrary to the facts, completely obliterating China’s great efforts and achievements in intellectual property protection.

Conclusion 6. China government’s support for enterprises to go global is not a government action to promote enterprises to acquire advanced technology from other countries through mergers and acquisitions.

Like other countries and regions in the world, China government supports powerful and qualified enterprises to invest abroad and expand the international market on the premise of observing the laws and regulations of the host country and international rules, and the government provides convenient services for enterprises’ foreign investment cooperation. The United States regards the China government’s support for enterprises to go abroad as a government action to promote enterprises to acquire advanced technology from other countries through mergers and acquisitions, which lacks factual basis.

Conclusion 7. There are a large number of investment and trade restrictions policies and behaviors in the United States.

There are a large number of investment and trade restrictions policies and behaviors in the United States that distort market competition, hinder fair trade and split the global industrial chain, which are detrimental to the rule-based multilateral trading system and seriously affect the normal development of Sino-US economic and trade relations.

Conclusion 8. The international trade friction provoked by the United States will ultimately harm the long-term interests of the United States.

As the main founder and participant of the international economic order and multilateral trading system after World War II, the United States should take the lead in observing multilateral trade rules and properly handle trade frictions with other member countries through the dispute settlement mechanism under the framework of the World Trade Organization, which is also a clear commitment made by the US government to the international community. However, since taking office, the new American administration has unilaterally emphasized "American priority", pursued unilateralism and economic hegemonism, abandoned international commitments, and provoked international trade frictions in all directions, which not only harmed the interests of China and other countries, but also damaged the international image of the United States itself, shaken the foundation of the global multilateral trading system, and will ultimately harm the long-term interests of the United States.

Conclusion 9. The extreme trade protection measures taken by the United States hurt global economic and trade relations.

A series of extreme trade protection measures adopted by the US government have destroyed the international economic order, harmed global economic and trade relations including Sino-US economic and trade exchanges, impacted the global value chain and the international division of labor system, interfered with market expectations, and triggered violent shocks in international finance and commodity markets, which has become the biggest uncertain factor and risk source for global economic recovery.

Conclusion X. China is confident, determined and capable of coping with various risk challenges.

For the trade war, China is unwilling to fight, not afraid to fight, and has to fight if necessary. We have strong economic resilience and broad market space, the industrious and intelligent people of China, and the support of all countries in the world that oppose protectionism, unilateralism and hegemonism. We are confident, determined and capable of coping with various risk challenges. No external factor can prevent China from developing and growing.

The healthy and stable development of Sino-US economic and trade relations is expected by the international community.

Sino-US economic and trade frictions are related to global economic stability and prosperity, and to world peace and development, and should be properly resolved. Peace between China and the United States is beneficial, but fighting is harmful. It is in the fundamental interests of the two peoples and the common interests of the people of the world to maintain healthy and stable economic and trade relations between the two sides, which is expected by the international community.

Conclusion XII. The open door of China will not be closed, but will only grow wider and wider.

Reform and opening up is the basic national policy of China and the fundamental driving force for the development of China. The direction of China’s reform will not be reversed, but will continue to deepen. China’s open door will not be closed, but will only get wider and wider. China will continue to deepen reform and open wider to the outside world in accordance with the established deployment and pace, comprehensively promote the rule of law and build a socialist country ruled by law.

Conclusion XIII. China adheres to the general trend and the right path and unswervingly upholds the multilateral trading system.

If you get the word, you will get more help, but if you lose it, you will get less help. Faced with the international situation of increasing uncertainties, instability and insecurity, China Do not forget your initiative mind has always walked with the world, followed the general trend, upheld justice and followed the right path, unswervingly safeguarded the multilateral trading system, unswervingly promoted the reform of the global governance system, always been a builder of world peace, a contributor to global development and a defender of the international order, and unswervingly promoted the building of a community of human destiny.

　　　　On July 2nd, Volvo Cars officially released its much-watched Sensus innovative technology sub-brand and the corresponding intelligent in-vehicle interactive system. This system, together with general-purpose Anjixing, Toyota’s G-BOOK, BMW’s connected driving and Mercedes-Benz’s My command, belongs to the "car networking" system, that is, the car is integrated with computer and Internet technologies, making the car more and more "intelligent". So what are the highlights of Volvo’s Sensus system? The following is a detailed answer for you.

　　　　Volvo Sensus Connect intelligent in-vehicle interactive system takes "multimedia cloud server" as the transmission platform, providing interconnection services and information interaction support, which can realize all-round functions such as multimedia entertainment, communication navigation, information sharing, remote control, sound control and after-sales reservation, bringing more convenient car experience.

　　　　Sensus intelligent vehicle interaction system is divided into two parts: Sensus Connect and Volvo On Call. Let’s introduce Sensus Connect first:

　

In the competition with the same class models, it is worth mentioning in terms of space performance. Let’s take a look at its performance.

First of all, from the appearance, the front face of BMW i4 has taken a delicate route and looks very atmospheric. At the same time, the headlight presents a solid design style, which is in line with consumers’ aesthetics. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Come to the car side, the car body size is 4785MM*1852MM*1455MM, the car uses eye-catching lines, the car side gives people a very beautiful feeling, with large-size thick-walled tires, the shape is quite eye-catching. In terms of the rear end, the overall shape of the rear end echoes the front face, and the taillights give people a very tough feeling, and the overall shape is still very attractive.

When I got into the car, the interior design took a spiritual route and was rich in functions. The steering wheel of the car is well designed and made of leather, which looks a little more calm. Let’s take a look at the central control. The car is decorated with a stylish and generous touch-control LCD central control panel, which makes the interior style impressive and the overall design of the central control is remarkable. Finally, let’s look at the dashboard and seats. The dashboard of the car presents an elegant design style, and the sports atmosphere is relatively in place. The car uses leather seats, which are wrapped in place and comfortable.

The BMW i4 matches the gearbox, which is 400KW and 795N.m, and its power performance is good.

The car is equipped with car networking, driving mode selection, remote control key, indoor ambient light, traction control (ASR/TCS, etc.) and other configurations, which greatly improves the convenience of using the car.

I wonder if you are excited about this car introduced today? If you plan to buy a car and the budget is not particularly adequate, this model is worth considering.

To say that the hottest car at the Chengdu Auto Show, it is BYD Xia. At the node of the arrival of the MPV wave, carrying the fifth-generation DM technology and BYD’s word-of-mouth, the first MPV of Dynasty Network is definitely the top stream in the top stream. But as a simple debut, the IPO time is expected to be in the second half of the fourth quarter of the MPV, and users with rigid demand may not be able to wait that long. If you want to buy an MPV now, who can replace it?

By the way, BYD Xia said it is 300,000 level MPV. Then we will compare it with this price as a benchmark.

The reason why these two cars are placed first is because they are the closest in size to the summer.

Summer: 5145mm x 1970mm x 1805mm, wheelbase 3045mm.

Saina: 5165mm x 1995mm x 1765mm, wheelbase 3060mm.

The size difference between the two cars is less than 10cm, and the space performance should be very similar. Toyota’s MPV is very interesting to drive, with a sense of dexterity that other models in the same class do not have. I think in addition to the old car companies’ grasp of the chassis foundation, the motor in the 2.5L hybrid system also plays a key role. 270N · m torque is not big, but it is more than enough to maintain a start. The chassis performs well in MPV, whether it is pitch or roll suppression.

But the drawbacks are equally obvious: although the new model is equipped with double-layer soundproof glass, the high-speed noise control is only medium, the third row has no child seat interface, and lacks intelligent functions such as automatic parking. Overall, this is a space-qualified MPV with interesting driving.

This should be the representative model of Japanese MPVs in everyone’s subconscious, especially the Odyssey, which can be said to be the existence of "provincial" MPVs in Guangdong Province, and the streets are full of Odysseys of various eras. In fact, everyone should be very clear about this car’s performance.

Honda’s handling, space, power performance and fuel consumption (hybrid version) are obvious to all, and the 2998 version has the highest discount 50,000, the cost performance is already very high. So if the budget is not particularly high, and do not want to buy domestic brands, then the current Odyssey is still worth buying.

The high vertical redundancy of the MPV does not cause the embarrassment of head space after adding a large battery. There are many more opportunities to wait in the car than other models. In addition, the MPV is the most suitable model for plug-in hybrids when you almost go out for a long time. The Trumpchi E9 is equipped with a large 25.57-degree battery + 2.0TM hybrid engine + 2-speed DHT gearbox, which is the dessert of the MPV.

As one of the largest cars in 300,000 level, under the blessing of hardware size, E9 is to have space and texture, power and texture, fuel consumption and texture, comfort and texture, configuration and texture. As an old MPV manufacturer in China’s own brand, Trumpchi E9 is the top MPV of GAC. Now the whole series of discounts 30,000 big, 300,000 you can even land the championship version, it is really fragrant.

Talking about MPV in China without mentioning GL8 is like opening a martial arts hall in Tianjin without visiting the wharf. You may also find that I have written the name of the car for other models, but GL8 has written the configuration name, because the price span of GL8 is too large. From the lowest 200,000 to the top 4-seat version of 800,000, as long as you want to buy MPV, GL8 always has the one that suits you, which is also the secret of GL8’s longevity.

　　In recent years, the booming takeaway industry has reshaped people’s daily lives and become an important breakthrough point for economic development and employment in various places. According to a report released by Meituan, in 2019, the total number of takeaway riders who earned income through the platform reached 3.987 million, an increase of 23.3% over 2018; in the first half of this year, the total number of riders who earned income on the Meituan platform reached 2.952 million, a significant increase of 16.4% year-on-year.

　　The relatively high income, stable salary payment and flexible working hours are the reasons why many workers are attracted to the food delivery industry. Wu Zhaoyun, a 35-year-old food delivery brother in Guangzhou, said that he has worked in factories, hotels and property companies. Since joining the food delivery team in 2017, he "feels that this career is very promising."

　　While the number of takeaway riders continues to grow, takeaway brothers have become a group with a high incidence of traffic accidents. In recent years, there have been vicious traffic accidents in many places in China where takeaway brothers have caused deaths due to running red lights and violating the rules.

　　The reporter learned from the Shenzhen traffic police department that in August this year alone, Shenzhen investigated and dealt with 12,000 traffic violations in the express delivery and takeaway food delivery industry, accounting for more than 10% of the total number of non-motor vehicle violations. The Shanghai medical emergency center healthcare workers said that they would encounter rider-related orders every week in August.

　　"Rush" is the core reason. One rider said the delivery time given to him by the platform around 2018 was 40 minutes per order, but it was later compressed to 30 minutes. "Sometimes it takes 20 minutes to get takeaway from the merchant, and the remaining 10 minutes I have to ride 3km, run into the community, and wait for the elevator to go upstairs," he said.

　　The main basis for the platform to compress time is the algorithm system based on big data and artificial intelligence. There is also a complete set of strict assessment mechanisms in cooperation with the algorithm system: on the one hand, the takeaway platform incentivizes takeaway riders to receive as many orders as possible with "price-per-order"; on the other hand, the platform strictly restricts riders through assessments such as on-time rate, bad review rate, and cancellation of order volume due to delivery reasons. The reduction in on-time rate means that takeaway riders lose the "order-taking advantage" in the platform’s algorithm, and will also be reduced in the internal ranking, missing various rewards.

　　This "algorithm plus assessment" mechanism has multiplied the psychological pressure of practitioners. One rider said that once he collided with an electric car, "the first thing he thought of when he got up was that he couldn’t time out, and he didn’t care about how the other party and himself were injured. Now I think it’s ridiculous."

　　Why are algorithms "out of control"?

　　Several industry insiders believe that the deep problems behind the "algorithmic dilemma" deserve attention.

　　On the one hand, the platform is "competing to the bottom", resulting in the "imbalance" of the algorithm.

　　Data show that as of the second quarter of 2020, Meituan takeaway and Ele.me have captured nearly 95% of the market share in the takeaway industry.

　　Ma Liang, a professor at the School of Public Administration of Renmin University of China, believes that the short and concentrated characteristics of the takeaway industry determine that competition among enterprises is increasingly focused on the speed of food delivery, resulting in algorithms that should have integrated multiple indicators, ignoring the safety and stress of riders.

　　"The food delivery industry has actually formed a’race to the bottom ‘, that is, constantly testing the bottom line indicator of delivery time. After exhausting all the competitive parameters, the pressure is pushed to the rider, resulting in the rider being at the limit and overloaded," he said.

　　On the other hand, complex employment relationships lead to the transfer of risk, resulting in the algorithm’s "default".

　　The reporter learned from the research that most food delivery riders have formed a complex employment relationship with the food delivery platform. Many food delivery riders often do not sign contracts directly with the platform, but sign contracts with third-party labor service companies through some apps, and the labor service companies change frequently. When an accident occurs, it is easy to lead to multiple parties kicking each other.

　　In a case of a takeaway rider hitting a pedestrian, the rider said that he joined a takeaway platform in September 2018. At first, the labor agreement on the app showed that the employer was Ningbo Yumi Company; in August 2019, the agreement on the app was changed to Hangzhou Bangmang Company. He did not know who the employer was. During the court hearing after the accident, neither Ningbo Yumi nor Hangzhou Bangmang admitted that Huang was his employee.

　　Liu Bo, the judge of the Huangpu District People’s Court in Guangzhou who was in charge of the case, said that in terms of the contract, the relationship between the rider and the labor service company is a labor relationship, but in fact the relationship between the labor service company and the rider is very loose. The platform uses the number of orders received and customer complaints to assess the rider, acting as an "employer." In the event of a traffic accident, the platform hides behind the labor service company and does not take any responsibility.

　　Under the current laws and regulations, the traffic police cannot punish the enterprise, but only the rider. In the event of a traffic accident, the rider, not the enterprise, needs to bear the cost of violating the law and the risk of disability and death.

　　Algorithms alone are not enough

　　In the face of social doubts, Ele.me said it would launch new features as soon as possible – "I am willing to wait 5 minutes/10 minutes more" buttons for consumers to choose from, while Meituan said it would improve the scheduling system to give riders 8 minutes of flexible time.

　　Some interviewees believe that to solve the dilemma faced by takeaway riders, the most important thing is that platform companies can face up to, respect, and truly protect the rights and interests of workers, rather than allowing algorithms to become cold tools that only make money for enterprises.

　　In recent years, in the face of the challenges of emerging business models, many places have begun to increase management efforts. For example, Foshan, Guangdong has built 89 fixed traffic safety education points to increase traffic safety education for delivery couriers and other groups; for takeaway enterprises with many traffic violations and weak traffic safety management, Foshan public security traffic police organized interviews with business leaders.

　　Ma Liang suggested that the emerging business will inevitably pose an impact and challenge to the existing laws and regulations, and the general laws involving the protection of workers’ rights and interests, occupational safety, and safe production need to be revised in a timely manner. Issues directly related to a certain industry also need to be responded to in a timely manner by new regulations.

　　In addition, the problems of the food delivery industry involve multiple departments, and the main regulatory departments should be further clarified to correct the disorderly competition behavior. Ma Liang also suggested that the food delivery riders belong to the "safety production problem in the flow" and should also be included in the assessment system of local governments to strengthen the local government’s supervision and law enforcement responsibilities.
