　　21st century business herald reporter Zheng Zhiwen Intern Wang Qingwei Shanghai Report

　　On November 25th, Chengdu Longquanyi Public Security Bureau reported a traffic accident on Chengluo Avenue in the district. When a small car was driving in the direction of Xihe River at the Shiling Interchange ramp of Chengluo Avenue, it collided with the vehicle in front at the intersection of Shiling subway station. Three people were slightly injured in the accident and all were treated in the hospital.

　　According to the video taken by the driving recorder of the rear vehicle, all the vehicles were waiting for the traffic lights at the intersection, and a white Tesla car suddenly rushed out and hit more than a dozen cars in a row. The scene of the accident was a mess, car parts were scattered all over the place, and many cars were seriously damaged.

　　On November 27th, Tesla responded to the cause of the accident. Tesla said that by checking the background data, it was found that when the collision occurred in the video, the accelerator pedal of the accident vehicle was depressed at a depth of 100%, and the vehicle speed increased from 54km/h to 132km/h at the time of collision. However, the brake light was not turned on because the driver stepped on the brake pedal, but because the collision in the video was not the first collision. After the first collision, the "multi-collision braking" function of the vehicle was triggered, so the brake light was turned on in the video. The background data also shows that the driver did not step on the brake pedal within 2 seconds after the collision in the video.

　　In view of the fact that the vehicle did not stop in time, Tesla said that by checking the background data, the driver stepped on the brake pedal 2 seconds after the collision in the video. However, combined with the background data and the damaged state of the vehicle, after the first collision, the front wheel of the vehicle has fallen off, the braking system pipeline has been damaged, and the vehicle has been unable to brake normally.

　　It is worth noting that this accident is not the first storm in Tesla’s braking, and related "brake failure" incidents have emerged in an endless stream in recent years.

　　The whole story of "Shanghai Auto Show Roof Rights Protection Event"

　　At the 2021 Shanghai Auto Show, two Tesla owners dressed in "brake failure" made a big fuss about Tesla booth demanding rights protection. Since then, Tesla has been shrouded in the suspicion of "brake failure".

　　On the afternoon of the auto show, Tao Lin, vice president of Tesla China, responded to this matter: Tesla had no way to compromise. The next morning, Weibo, the official of Qingpu Branch of Shanghai Public Security Bureau, issued a notice saying: Zhang, a woman involved in the "Tesla Auto Show Encountered Owners’ Rights Protection" incident, was sentenced to administrative detention for five days for disturbing public order, and Li was given an administrative warning for disturbing public order.

　　Since then, the two sides have opened the curtain of going to court, and whether Tesla has "brake failure" has also attracted much attention.

　　On May 6, 2021, Ms. Zhang formally sued Tesla (Shanghai) Co., Ltd., Tesla (Beijing) Co., Ltd. and Tao Lin, global vice president of Tesla. Ms. Zhang believes that after the rights protection incident at the Shanghai Auto Show, some remarks made by Tao Lin and Tesla officials were intended to create a negative image of the plaintiff’s unreasonable troubles and professional car troubles, which violated their reputation and caused troubles to their lives. These remarks include "all the recent negatives are her contribution", "only willing to pay high compensation" and the so-called "there is a team from Beijing". Ask the defendant to stop the infringement of the plaintiff’s reputation right, apologize to him and pay 50 thousand yuan for mental damage.

　　Two years later, Tesla issued a document in response to the failure of the female car owner of Tesla’s roof rights protection: the female car owner of Shanghai Auto Show advocated that the woman sued Tesla’s reputation right dispute case and personal information protection dispute case. After trial, the court of first instance decided to reject all the claims of Ms. Zhang in the two cases. On November 22, 2023, Tesla v. the case of infringement of the reputation right of female car owners in Xi ‘an "Shanghai Auto Show Incident", the court made a first-instance judgment, and found that Ms. Li in Xi ‘an was guilty of reputation infringement, and she had to publicly apologize to Tesla and compensate for the losses, and at the same time bear the vehicle appraisal fee.

　　Recently, according to Tesla’s news, the court made the latest judgment in the case of Tesla v. another female car owner in Xi ‘an, who was involved in the right to defend the roof of Shanghai Auto Show, and found that Ms. Li in Xi ‘an was guilty of reputation infringement, and she had to apologize to Tesla publicly and pay 2,000 yuan, and at the same time bear the vehicle appraisal fee of 20,000 yuan. After identification, there is no braking problem in the vehicle involved.

　　It is reported that before this, the judgment was made in December 2021, and the result was that Ms. Li won the case. Tesla then filed an appeal, and the Xi ‘an Intermediate People’s Court ruled that the case was sent back for retrial. On November 9, 2023, the weiyang district court made a new judgment, and the verdict was that Ms. Li lost the case. For the result of Tesla’s victory in the first instance, Ms. Li said that she respected the court’s decision, but she would appeal again.

　　It is worth noting that in March 2021, Weibo, the "Tesla Customer Support", said that the accident liability certificate issued by the traffic police showed that Mr. Zhang (the owner’s father) was found to have violated the relevant laws on safe driving and keeping a safe distance from the vehicle in front, and should bear full responsibility for the accident.

　　After the "Shanghai Auto Show Rights Protection" took place, Tesla provided the data one minute before Ms. Zhang’s vehicle accident, and made a written explanation, which stated that when the driver stepped on the brake pedal for the last time, the data showed that the vehicle speed was 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9bar. After that, the driver stepped on the brake pedal more, and the brake master cylinder pressure reached 92.7bar. Then, the forward collision warning and automatic emergency braking function started (the maximum brake master cylinder pressure reached 140.7bar) and played a role, reducing the collision amplitude. 1.8 seconds after the ABS action, the system recorded the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease, and before the collision, the vehicle speed decreased to 48.5 kilometers per hour. Through the inspection and analysis of vehicle data and on-site photos, it is found that ABS works normally during the braking period of the vehicle, and the functions of forward collision warning and automatic emergency braking are started and played a role, and no abnormality is found in the vehicle braking system.

　　At this point, the dispute over rights protection at the Shanghai Auto Show has also come to an end for the time being. Although Tesla won the rights protection, the price it paid was also heavy. In the face of rights-defending car owners, Tesla CEO Musk dissolved the public relations department and showed a tough attitude of refusing to apologize. Tao Lin, global vice president of Tesla, publicly told the media that Tesla had no way to compromise and asked consumers to strengthen education and study. This attitude caused dissatisfaction among many car owners in China, which made Tesla’s share price plummet at that time, and its market value evaporated by hundreds of billions of dollars overnight.

　　In the lawsuit with Ms. Li, Tesla asked Ms. Li to pay 5 million yuan in the first instance, but the amount of compensation awarded was only 2,000 yuan. On November 27th, Tesla said that it would continue to appeal. The incident caused huge losses to it, and the loss of Tesla’s orders and goodwill was as high as 100 million yuan as assessed by the judicial evaluation agency.

　　Give up the "single pedal" mode

　　In the storm of Tesla’s "brake failure", the "single pedal" mode seems to have become the target of public criticism.

　　This year, Tesla recalled 1.1 million Tesla cars around the world. The announcement on the website of the General Administration of Quality Supervision, Inspection and Quarantine once said that drivers were not allowed to choose the energy recovery braking strategy for vehicles within the scope of this recall; At the same time, it may not provide enough reminder for the driver to step on the accelerator pedal for a long time. The superposition of the above factors may increase the probability of mistakenly stepping on the accelerator pedal for a long time, which may increase the risk of collision and pose a safety hazard.

　　In the analysis of professionals, Tesla’s kinetic energy recovery technology is the strongest in the industry. Through kinetic energy recovery, it can save about 20% of energy and improve the endurance by about 15%-20%. Moreover, Tesla’s energy recovery mode is mandatory default mode, and the owner can’t set it by himself and can’t choose to turn it off. Most of the energy recovery modes of other electric vehicles on the market give the owners the freedom to choose.

　　Many users reported to 21st century business herald that the "single pedal" mode was not suitable for use at first, but it was really "fragrant" after being used to it, but some users still could not accept the "single pedal" mode.

　　Tesla said that the "single pedal" mode is more convenient and efficient. However, there are also risks. A survey report in 2021 showed that the National Highway Traffic Safety Administration (NHTSA) had investigated 246 cases of Tesla’s runaway acceleration, and all 246 cases were caused by stepping on the wrong pedal.

　　"There is no evidence that there is any fault in the accelerator pedal assembly, motor control system or braking system that leads to accidents, and there is no evidence that design factors will increase the possibility of pedal misuse." NHTSA said.

　　The so-called "single pedal" mode, in simple terms, can realize starting, accelerating, decelerating (braking) and other operations only by controlling the switch pedal. In this mode, kinetic energy recovery can not only save electricity, but also reduce the use of brakes, which can improve the cruising range of electric vehicles. Although the "single pedal" mode is not only equipped with one pedal, it is still equipped with a brake pedal. However, in this mode, users put their feet on the accelerator pedal instead of the brake pedal for a long time, which changes the way users are used to driving traditional fuel vehicles, but there may be potential safety hazards in an emergency.

　　Tesla has cancelled the "Kinetic Energy Recovery Adjustment Option" since the beginning of 2021, that is, on Tesla cars, this function is mandatory, not a switchable option. According to Tesla, after the OTA recall, car owners who like energy recovery braking can continue to choose the "standard" mode, and control the speed by "foot feeling", while improving the endurance of the vehicle by 10%-20% and reducing the wear of brake discs and pads. Car owners who are not used to this function can now choose the "low" mode to transition.

　　Although Tesla returned the option of kinetic energy recovery to the public, there are still other doubts that not recognizing the wrong operation of the owner can explain all the accidents of Tesla vehicles out of control and brake failure. Tesla’s roof rights car advocates that the top of Ms. Weibo is the video of Tesla Hainan accident released by another well-known Tesla rights car owner. The car owner can’t step on the brakes, but the staff will open the video that still can’t step on the brakes. In its latest Weibo, it forwarded a video recorded by another Tesla owner who obviously stepped on the brake system but mistook the owner for stepping on the accelerator.

　　There is also a question about whether Tesla’s data is reliable. "All data collection is based on Tesla’s unilateral provision, and Tesla only records the data collected by itself in the background. Is this data record objective? For example, if the owner steps on the brake, but can’t step on it, is it recorded in the background that he didn’t step on it? The owner did not step on the acceleration, and the vehicle automatically accelerated. Will the background also be recorded as acceleration, which means that the owner is stepping on the switch? "

　　Regarding the data problem, industry experts also said that there is no institution in China that has the professional ability to detect the data of smart electric vehicles. Zhang Xiang, a member of the automotive industry expert think tank of the Ministry of Industry and Information Technology, said in an interview with the media: "Now the institutions on the market basically only test mature and long-developed technologies, that is, mainly test traditional cars. As a smart car, Tesla can’t be tested according to the standards of traditional cars. Moreover, Tesla’s time to market is not long, and the technical iteration is changing with each passing day. Our regulations and industry standards have not kept up. "

　　There have been different opinions about the real cause of Tesla accident. Whether it is the owner’s "habitual thinking" or the quality of car design, the result of frequent vicious traffic accidents is unacceptable. At the moment of rapid development of new energy vehicles, car safety is the most important issue, and it needs the joint efforts of many parties to form effective supervision.

　　Faced with the increasing demand for early repayment of property buyers, some banks have cancelled the function of early repayment of mobile banking, which requires a long appointment time and requires offline outlets to apply for mortgage … … The phenomenon that mortgage repayment is difficult in advance has attracted the attention of the regulatory authorities.

　　On February 24th, the reporter of China Business News learned that China Banking and Insurance Regulatory Commission recently held a special meeting, asking banks to speed up the processing of the backlog of applications and do a good job in early repayment. At the same time, special risk warnings are issued to remind consumers to be alert to illegal intermediary induction, recognize the risks of illegally using business loans to replace mortgages, and protect their legitimate rights and interests.

　　The person in charge of relevant departments in China Banking and Insurance Regulatory Commission stressed that it will continue to strengthen the supervision over the illegal use of business loans and the illegal inflow of consumer loans into the real estate sector.

　　In addition to the mortgage problem, the heads of the above departments also responded to issues closely related to financial consumers such as pension and financial management.

　　On the difficulty of repaying loans in advance: speeding up the processing of backlog applications

　　"From the market reflection and our understanding, the number of early repayment settlements has increased significantly, the processing time limit has been shortened, and the problem of early repayment difficulties has gradually eased." The person in charge of the relevant departments in China Banking and Insurance Regulatory Commission said that at present, commercial banks are optimizing related financial services and doing a good job in prepayment. Some banks have formulated special customer prepayment service schemes and processes to co-ordinate online and offline service channels to ensure the predictability of repayment time. Some banks carry out multi-channel service docking and set up special seats for mortgage prepayment hotline to facilitate customer consultation and business handling. Some banks deploy prepayment reservation function in online channels such as mobile banking to improve service efficiency.

　　China Banking and Insurance Regulatory Commission attaches great importance to the protection of consumers’ rights and interests. As early as February 9, it held a forum with the People’s Bank of China for some commercial banks, demanding that commercial banks strengthen the customer-centered concept, do a good job in customer prepayment service in accordance with the contract, and improve the service quality.

　　China Banking and Insurance Regulatory Commission said that in the next step, together with relevant departments, we will continue to guide commercial banks to provide real estate financial services in accordance with the contract, smooth online processing channels, speed up the efficiency of approval processing, and ensure that customers run less and process quickly. At the same time, we will continue to strengthen supervision over the illegal use of business loans and the illegal inflow of consumer loans into the real estate sector. If consumers need to repay loans in advance or other financial services, please consult formal financial institutions such as banks to understand the relevant situation, so as to avoid being misled by illegal intermediaries and protect their legitimate rights and interests.

　　About personal pension: over 24 million accounts have been opened.

　　The development pattern of multi-subject participation, multi-product supply and meeting diversified pension needs has taken shape.

　　The First Financial Reporter learned from China Banking and Insurance Regulatory Commission that in terms of commercial pension financial reform, as of January 2023, the balance of specific pension savings business was 26.32 billion yuan; There are 51 old-age wealth management products with the characteristics of "stability, long-term and inclusiveness", and the cumulative purchase amount of 470,000 investors is 100.4 billion yuan; The total premium of exclusive commercial endowment insurance is 4.27 billion yuan, and the number of policies is 374,000. Among them, the number of policies for new industries, new formats and flexible employees exceeds 60,000, and the premium exceeds 170 million yuan. The commercial pension pilot was launched on January 1 this year. At present, National Pension Insurance Company and China Life Pension Insurance Company have started their business for consumers, and the other two pilot companies are also actively preparing products.

　　According to the data of China Banking and Insurance Regulatory Commission, in 2022, the old-age annuity insurance realized the original insurance premium income of 64.2 billion yuan, the number of policies was 22.52 million, and the accumulated liability reserve at the end of the period was 665.9 billion yuan; Together with other commercial insurance with the function of old-age security, the accumulated liability reserve of commercial old-age insurance has exceeded 5 trillion yuan at the end of the period.

　　In the development of personal pension system, at present, commercial banks have opened more than 24 million personal pension fund accounts; Bank insurance institutions are introducing a variety of financial products such as savings deposits, wealth management products and commercial endowment insurance for participants to invest and buy in an orderly manner.

　　In terms of the reform of pension financial institutions, China Banking and Insurance Regulatory Commission issued the Notice on Standardizing and Promoting the Development of Pension Insurance Institutions in 2021, which clearly required pension insurance institutions to stick to their positioning and deepen product and service innovation, and became an important force to promote the high-quality development of the pension financial market.

　　The person in charge of the relevant departments in China Banking and Insurance Regulatory Commission said that various institutions are actively transforming according to the notification requirements, gradually adjusting their business structure, and further focusing on the development of the main business of providing for the aged.

　　About the new regulations on asset management: the net value rate of products increased by 80.4 percentage points.

　　The person in charge of relevant departments in China Banking and Insurance Regulatory Commission said that the rectification and transformation in the past five years have laid an important foundation for the wealth management industry to enter a new stage of development. At the same time, the new stage has put forward new requirements for the development of wealth management industry, and there are still some problems and deficiencies at present. For example, the wealth management product system is not rich enough, and the diversified wealth management needs of serving the people need to be improved; The management and disclosure of net product value are not standardized, and the construction of investment and research system of wealth management companies still needs to be strengthened; Investor services and education need to be strengthened.

　　After the release of the new asset management regulations in 2018, China Banking and Insurance Regulatory Commission solidly promoted the rectification and transformation of wealth management business, made great efforts to rectify all kinds of asset management chaos, combined punches to severely punish violations, and took various measures to guide banks to strictly formulate and implement the rectification plan for stock business, and accelerated case handling in a safe and orderly manner.

　　After nearly five years of comprehensive management, the risk of shadow banking has significantly converged, the chaos of industry risks has been fundamentally reversed, and the task of rectification during the transition period of new asset management regulations has been generally completed.

　　The first financial reporter learned that up to now, the capital preservation and financial management have been cleared, and the basic pressure drop of expected income products has been completed. Chaos in industries such as idling nesting has been significantly reduced, and multi-layer nesting has been basically eliminated. Inter-bank wealth management was significantly reduced by 99.9% compared with the peak value. The maturity mismatch was fundamentally reversed, and the pooling operation was corrected. Non-standard investment dropped sharply, and the non-standard creditor’s rights assets of wealth management investment issued by banks decreased by 89.2% compared with the new asset management regulations. The expansion of high leverage was restrained, and the average leverage ratio of products decreased by 7.2 percentage points compared with the peak value.

　　According to the person in charge of the relevant departments in China Banking and Insurance Regulatory Commission, the bank strictly formulated the rectification plan for submitting the wealth management stock business, locked in the base of assets to be disposed of, and took various measures to promote the implementation of rectification. Most of the stock assets have been successfully disposed of, and the task of rectification in the transition period has been completed as a whole. For a small amount of difficult-to-dispose assets left by individual banks, they were included in the case disposal according to regulations, and the clean-up was accelerated. The overall progress was better than expected, and the case disposal entered the final stage.

　　The successful completion of the five-year rectification and transformation of wealth management business marks the "clean start" of wealth management companies and the industry has entered a new stage of high-quality development. At present, the net value rate of products exceeds 95%, which is 80.4 percentage points higher than when the new asset management regulations were issued.

　　By the end of 2022, the scale of wealth management products in the whole market was 27.7 trillion yuan, and the annual income for investors was 880 billion yuan. Since the release of the new asset management regulations, the accumulated income has been 4.4 trillion yuan, which has effectively broadened the property income channels of urban and rural residents and promoted the realization of common prosperity.

　　On May 5, 2017, people with big plane dreams came to a small slope outside the fourth runway of Shanghai Pudong International Airport early, waiting for the exciting moment. On this day, it was the first flight day of C919, a large jet passenger plane independently developed by China, and the small earth slope outside the runway was affectionately called "Wangjiupo".

　　With the roar of the engine, the first C919 large passenger plane, piloted by captain Cai Jun and co-pilot Wu Xin, took off from the fourth runway of Pudong International Airport at 14: 00, rushed into the sky, and landed successfully 79 minutes later. After nine years of scientific research, numerous tests and technical debugging, there is once again the shadow of domestic large aircraft in the blue sky, which indicates that China has entered the ranks of a few countries with the ability to develop large passenger aircraft.

　　Now, more than two years have passed. What’s the progress of airworthiness certification of C919 passenger plane? When can Chinese get on a large domestic plane? Recently, the reporter came to China Commercial Aircraft Co., Ltd. for a field visit.

　　Yun -10: Leaving an innovative gene is an attempt to commercialize domestic aircraft.

　　Arriving at the Pudong base of China Comac Shanghai Aircraft Manufacturing Co., Ltd., I saw a large plane with a white fuselage and several blue and white stripes sleeping peacefully on the lawn of the industrial park, with a bright red flag on its tail. This unique large passenger plane in the world soared in the blue sky of China more than 30 years ago, and its name was Yun -10.

　　Boarding the Yun -10 plane, the reporter was shocked by the industrial level at that time. The throttle lever, pedals, various instrument panels and indicator lights in the cockpit are reasonably arranged and fully functional. In addition to the seats for the main driver, the co-pilot and the pilot, there is also a seat for the mechanic. When the aircraft breaks down in flight, the mechanic can go down to the inside of the aircraft from the passage next to the seat for maintenance. When you come to the cockpit, the passenger seat is no different from the common big plane now, except that the distance between the front and back of the seat is larger, the ride experience is more comfortable, and there is an ashtray on the armrest.

　　In August 1970, with the approval of Comrade Zhou Enlai, the state agreed that the report on trial production of transport aircraft in Shanghai should be centralized by the Ministry of Aviation Industry. The mission name is "Project 708" and the aircraft code is "Yun -10". According to statistics, at that time, more than 300 factories, research institutes and universities in 21 provinces, autonomous regions and municipalities participated in the development of Yun -10 aircraft.

　　On September 26th, 1980, Yun -10 successfully made its first flight in Shanghai. Subsequently, Yun 10 flew all over the country, reaching 10 cities, including Beijing, Harbin, Urumqi, Guangzhou, Kunming, Chengdu, Hefei and Zhengzhou. The longest time for a single flight was 4 hours and 39 minutes, and it completed a scientific test flight that flew over 3,600 kilometers in 3 hours and 42 minutes. Its performance and use characteristics fully met the design requirements. Yun -10 also flew over the Himalayas to Tibet seven times, transporting more than 40 tons of urgently needed materials for Xizang Autonomous Region.

　　Although the Yun -10 aircraft project was not officially put into commercial use for various reasons, the Yun-10 spirit of "independence, strong cooperation, selfless dedication and continuous innovation" has been passed down from generation to generation by large aircraft people.

　　Next to the lawn where Yun -10 plane docked, there stands a sculpture engraved with the four characters "Never give up", which is a solemn promise from the heart of the big plane people and the earnest expectation of hundreds of millions of people for the early commercialization of domestic big planes.

　　Time has entered the new century. In February 2000, the state decided to support the production of domestic civil aircraft and accelerate the development of regional air transport. In June, 2002, the State Development Planning Commission issued a document officially approving the establishment of the new regional aircraft project. The result is a new turbofan regional plane that has soared in the blue sky of China today — — Arj21 (advanced regional jet for 21st century) means advanced jet regional aircraft in the 21st century. ARJ21-700 is its basic model, and it is the first time that China has developed and produced regional aircraft in strict accordance with the internationally accepted regulations on aviation airworthiness management.

　　ARJ21: Delivered the 21st aircraft, accumulating valuable experience for the civil aircraft industry.

　　Not long ago, on November 29th, Comac China delivered the 21st ARJ21-700 aircraft to its customers. Talking about the differences between civil airliners and other aircraft, Ye Chao, deputy director of ARJ21 Division of China Comac Shanghai Aircraft Manufacturing Co., Ltd., has a lot to say: "The independent development of a jet regional aircraft needs to go through the processes of design, trial production, test flight, evidence collection, production, etc. This is not all. To make the aircraft truly commercialized, it must be tested by the market. If the requirements of airlines cannot be met, the cost performance ratio is low, and the experience of drivers, flight attendants and passengers is poor, the mission of the aircraft will not be truly completed. "

　　In the process of design and development, the ARJ21-700 aircraft has fully considered the number of seats, comfort and the needs of the aviation market in western China. Compared with similar aircraft, the cabin of ARJ21-700 aircraft has a higher and wider cabin, the cabin height is more than 2 meters, reaching the same cabin comfort as that of narrow-body aircraft, and the cabin height is close to 1 meter, which can provide more luggage space for passengers. The economy of the aircraft is also more prominent, and the engine fuel consumption is low. In order to adapt to the complex geographical environment in the west of China, the ARJ21-700 aircraft pays attention to take-off and climb performance in design, and can take off and land in a short distance, which has a strong advantage in the adaptability of western routes and western airports.

　　Although customers’ needs were fully considered in the design and manufacture, when facing the customer representatives seriously, Comac found that there were many details to be perfected. Because, from "product" to "commodity", the difference is not just one word, but also thousands of times of self-improvement and continuous collision with customers.

　　In Ye Chao’s view, there were three "self-revolutions" on the sales road of ARJ21-700. "When we sold the plane to Chengdu Airlines for the first time, it was the first time that we delivered the plane to our customers. During the continuous running-in, we found that some problems that we had never thought of were exactly the concerns of our customers. The second time ‘ Self-revolution ’ When the plane was delivered to Tianjiao Airlines. We have changed from serving one customer to serving two customers, which requires us to be more refined in technology and operation specifications. Now we are facing the third time ‘ Self-revolution ’ New customers such as Air China, China Eastern Airlines and China Southern Airlines will put forward more new requirements for our products. In the future, we should look at production from the perspective of creating handicrafts. "

　　Since the commercial operation of the ARJ21-700 in June 2016, the optimization and improvement of the aircraft production process has been carried out almost every day. "For example, the pilot’s operation has been greatly modified to reduce the pilot’s workload; In order to reduce the noise in the engine room, the conventional sound insulation cotton material is replaced by metal damping layer and rubber sound insulation material; In order to reduce the airflow noise at the air outlet of the air conditioner, silencers are installed, and there are various optimizations for flight attendants and aircraft maintenance personnel. " Ye Chao said.

　　With more and more orders, the mass production capacity of ARJ21 has gradually improved. In 2017, it will produce 4 aircraft, in 2018, 11 aircraft, and strive to produce more than 20 aircraft in 2019. Behind the digital beat is the continuous improvement of the overall efficiency of the workstation and the efficiency of skilled workers. Comac China has continuously promoted the innovation of production management in terms of process technology, on-site management, production operation control and so on. From January to September this year, the batch production rate of ARJ21 aircraft increased by 76.9% compared with the same period in 2018.

　　The development of ARJ21 regional jet has accumulated valuable experience for the development of China civil aircraft industry. After the whole process of jet regional aircraft design, trial production, test flight, evidence collection, production, delivery and operation, China has the development capability and airworthiness certification capability of jet regional aircraft, and people have more confidence in the future of large passenger aircraft projects.

　　C919: All tests are carried out in parallel, and the test will be prepared for "evidence collection".

　　In the avionics system comprehensive laboratory of Comac Shanghai Aircraft Design and Research Institute, researchers are busy, and the indicator lights are flashing on the rows of computers. On the monitors one by one, the program codes pass by in turn, and the C919 aircraft is being tested and verified here.

　　Walking into the iron bird test-bed of C919 aircraft, the test-bed in front of us looks like an "iron bird", except that it can’t fly, and its shape and internal structure are basically the same as the real C919 aircraft, so it can be called a simulation aircraft. The integration tests of flight control, landing gear, hydraulic system, etc. are all completed here. After the command is issued from the console, Iron Bird completes the relevant specified actions, confirms and verifies that the system design meets the requirements of product development, and ensures flight safety. The international mainstream aircraft manufacturers have completed the technical verification and technical improvement of related models through the Iron Bird test bed. "In addition, it has another function: when the flight test of the C919 aircraft fails, we can simulate it through the iron bird test bed and find a solution to the failure." Li Tao, director of the construction of the State Key Laboratory of Civil Aircraft Simulation Flight of Shanghai Aircraft Design and Research Institute, said, "At present, we are intensively carrying out the airworthiness verification test of the laboratory."

　　Isn’t the C919 plane already empty? What are the researchers still busy with?

　　"We are working on the airworthiness certification of the C919 passenger plane, that is, ‘ Textual research ’ . At present, laboratory tests are being carried out here, in addition to on-board ground tests, flight tests, simulator tests and supplier product identification tests. After the success of the R&D test flight of the C919 passenger plane in 2017, it still needs several stages of test flight and airworthiness evidence collection before it can be delivered to the airlines. " Li Tao said.

　　In order to ensure the efficient ground test and flight test on board, "in October this year, 105 aircraft completed the first test flight, and the number of aircraft used for flight test will reach 6 in the future, and related flight test work is being carried out in parallel." Nan Guopeng, captain of 105 aircraft of C919, introduced.

　　Simulator tests are also being carried out in an orderly manner in Shanghai Aircraft Design and Research Institute. Boarding the C919 passenger aircraft engineering simulator, this equipment looks like a big ball, and its interior is almost the same as the real aircraft cab. Li Tao introduced: "The simulator can undertake the test tasks such as aircraft control law evaluation, cockpit evaluation and safety evaluation. At the same time, it can also undertake the training and training of test flight crews to help pilots understand aircraft performance as soon as possible. "

　　It is understood that before the C919 large aircraft is delivered for use, it is necessary to obtain three certificates, namely: type certificate (TC), indicating that the aircraft design is safe and seaworthy; Production license (PC), which indicates that the aircraft manufacturing system meets the requirements and can be produced on a large scale; Single Airworthiness Certificate (AC) proves that a single aircraft is in a safe and available state, which is equivalent to the "driving license" of a car. These work plans will take two to three years to complete. If they go well, Chinese will be able to take a large domestic plane designed and manufactured by himself in the near future.

　　In addition to the joy and pride of flying in a large domestic plane, the development of C919 has a long-term strategic significance. It is not a simple product, nor is it an ordinary commodity. The manufacture of large passenger aircraft is known as the "crown of modern industry", which plays a very significant role in driving the civil aviation industry and modern industry.

　　From the perspective of aviation industry, with Shanghai as the leader, more than 200 enterprises and nearly 200,000 people from 22 provinces and cities including Shaanxi, Sichuan, Jiangxi, Liaoning and Jiangsu participated in the development and production of large passenger aircraft projects. The China civil aviation industrial chain, value chain and innovation chain driven by the C919 large passenger aircraft have great energy, and at the same time, it has promoted the establishment of 16 joint ventures in airborne systems such as avionics, flight control, power supply, fuel and landing gear, which has promoted the civil aircraft industry in China.

　　From the perspective of upgrading the modern industrial level, a commercial aircraft consists of 3 million to 5 million parts. These parts need to be produced by thousands of suppliers, which can promote the group breakthrough of key technologies in the fields of new materials, modern manufacturing, advanced power, electronic information, automatic control, computer and many other basic disciplines. "There are many domestic suppliers involved in the parts of the C919 passenger plane, and the fuel tanks, valves and landing gear equipment of the hydraulic system are all produced in China. Through the C919 project, we have grown together with our suppliers. " Li Tao said.

　　At dusk, when leaving Shanghai Aircraft Design and Research Institute, the research building was still brightly lit. In order for the C919 to be delivered as soon as possible and soar in the sky, another night for technicians began … …

　　Interview notes

　　It takes only 4 hours and 18 minutes to get from Beijing to Shanghai by high-speed train, but it is not necessarily faster than the high-speed train, not counting the waiting time for the flight to take off and queue up. However, this reporter still chose to fly because he had a question in his heart — — When can we get on the big plane made by Chinese himself?

　　Not long ago, I was chatting with a friend. When he heard that all the large passenger planes we are taking now are foreign products, his face showed a very surprised look: "What? However, our fighter plane, the National Day military parade is so beautiful, and manned space flight has already sent astronauts out of the earth. How can we buy a foreign plane? " The reporter told him: "It won’t take long. I will definitely bring you back the latest progress when I go to Comac for an interview this time. "

　　The plane rushed into the sky and entered the stratosphere. The reporter took out the "Safety Tips" from the front seat pocket and saw that the plane on flight CA1855 was Boeing 787. Thinking of a news I just saw recently, the order for C919 large aircraft has exceeded 1,000. Maybe a few years later, the reporter will watch Safety Tips again, and the models on it will be different.

　　With countless questions, I came to Pudong base of Shanghai Aircraft Manufacturing Co., Ltd. and Shanghai Aircraft Design and Research Institute. The reporter finally knew why civil aircraft manufacturing was so difficult. What is carried on it is not goods, nor one or two people, but dozens and hundreds of lives, and there is no room for any safety problems. In addition, the performance requirements of civil aviation aircraft are also very high. During the service period, an aircraft generally has to go through 60,000 flight cycles (take-off and landing) and 90,000 flight hours, with a service life of 30 years or more. Even some seemingly unremarkable parts on the plane must be used stably and safely for decades. In order to compete with the world aviation market, the large aircraft we build must be safer, more comfortable, more environmentally friendly and more economical than others, so as to have a broad market.

　　The big plane people are working hard for all this.

　　In an interview, the reporter really felt their busyness and dedication. The interview was interrupted several times by phone calls, and the interviewee repeatedly pressed the phone for fear of influencing reporters to ask questions. When a reporter asked a researcher at Shanghai Academy of Aeronautics and Astronautics, "Are there any touching stories in your work?" He smiled and said, "It’s nothing. Everyone usually completes the test task seriously." The colleague sitting on the side couldn’t help it. She grabbed the conversation and said to the reporter, "Our researchers are really selfless. Many technical backbones are in their thirties and forties, old and young. In order to complete the airworthiness forensics work as soon as possible, they basically work overtime every day. You will know when it gets dark." Hearing this, the former researcher who said there was no story was somewhat silent. He said, "Last Friday, I got home after 10 o’clock in the evening and found that my wife didn’t let the children sleep. When I thought about it, I went out early and returned late. The child has not talked to me for a week. " These little details permeate all aspects of the interview, which is moving.

　　When leaving the interview, the reporter remembered the 16 Chinese characters hanging on the wall of the C919 assembly workshop — — Long-term struggle, long-term research, long-term hardship and long-term dedication, after the delivery of more than 20 ARJ21, the C919 will also be delivered in the next two or three years, and the CR929 wide-body passenger aircraft jointly operated by China and Russia will also start construction in the next few years.

　　Let’s look forward to it. In the blue sky, there are more and more domestic passenger planes.

How do hundreds of dramas show their magical powers and become explosions? A text will take you to understand their "secrets".

The costume drama continued to dominate the screen and the Republic of China drama made a stunning appearance.

From the perspective of the times, the number of dramas in the Republic of China is not comparable to that of costume dramas, but there are also many bright works.

After more than two years of official propaganda, Life as First Seen finally got new news. Once again, the "three rides" performed the drama of the Republic of China. And after the "Detective of the Republic of China", the "Detective of the Republic of China" was built, and the detective drama of the Republic of China was attacked again.

Modern love is still sweet, and the explosion in urban workplace continues.

Times return to modern times.

There has never been a lack of attractive combinations of handsome men and beautiful women in sweet pet love dramas, and LAI KUAN LIN’s What Love Should Be, which is now a hit, has completely opened the upsurge of "brother-sister love" in the second half of the year.

Next, Yang Mi and soso in the 28 Law of Love, and Wang Anyu in Chidao will all start a vigorous "New Year’s Love" in the play.

A series of main melody dramas are equally interesting.

"Courtyard of the County Party Committee" and Blossoms Shanghai are both starred by directors who have been away from the screen for many years.

In addition to Three-body, Ball Lightning will be escorted by Liu Cixin, and the first sci-fi dramas are expected to bring surprises to everyone.

The game of hundreds of dramas has its own advantages. From this, we can also observe the "change and invariability" of the drama market.

The ancient puppet is still a beacon, but on the basis of increasing homogenization, who can break the spell and become the next Dream of China?

Sweet pet drama is still a major drama. With the rise of women’s power, the theme of "brother-sister love" has become a new topic.

It is worth mentioning that the theme of the main theme drama is blossoming, and the blessing of powerful actors and famous directors is even more exciting. IP film and television is a cliche, but the development of sci-fi dramas has given us a little more hope.

So, which work are you looking forward to most?

Against the background of the cold new car listing scene last week, this week’s new car market is rich enough, with eight new cars landing in the national auto market this week. Among them, Cadillac released a brand-new luxury model XTS, with a starting price of 349,900 yuan, and the Fox ST, which is an opponent of golf GTI, was finally sold in China, and it became the most powerful sports model this week in 6.5 seconds.

● Na Zhijie Big 7 SUV Edge Evolution Edition

Highlights of new cars: allocation and price increase, power improvement and sales of 224,000-270,000 yuan.

Three evolution versions of Dongfeng Yulong Nazhijie 7 SUV have been officially launched recently.

With the increase of configuration, the price will certainly go up, but for the "die-hards" like the author, the comparison result between the prices of new models and current models is really a bit puzzling. As shown in the table at the beginning of the article, the pre-sale price of the three models increased by 6,200 yuan, 8,500 yuan and 2,000 yuan respectively. If the addition items of the three evolution models are all the above five items, then the price difference is really a bit big.

Cctv news(Reporter Zhang Xiaolin, Li Wenliang and Wang Xiaoying) Through an agricultural product testing box, pesticide residues and harmful additives in food and agricultural products can be quickly detected. Qualified products are labeled with two-dimensional codes, and consumers can scan the codes to see the origin of the products, and how the water quality, light and pests are there.

At the second Digital China Construction Achievements Exhibition, scientific and technological products like this covered all walks of life. The integration of digital technologies such as big data and cloud computing with traditional industries is making our lives smarter.

Big data promotes modern agriculture to improve quality and efficiency.

Digital pastoral, smart agriculture, big data and traditional agriculture will also produce unexpected sparks.

In xiuwen county, Guizhou, big data has improved the scientific and technological content of Xiuwen Kiwifruit. By building an agricultural big data Internet of Things platform, xiuwen county has completed the construction of data collection systems and system platforms for five kiwifruit plantations, covering an area of nearly 40,000 mu, realizing the scientific and precise management of kiwifruit planting and strengthening the product quality assurance, and has been listed as a provincial key demonstration site.

The sustainable collection and update system of big data on planting and breeding and the application of big database of agricultural products market and sales price have promoted the industrial transformation and upgrading in rural areas.

The e-commerce platforms such as Guinong. com have developed new sales service models such as online customization of green and pollution-free high-quality agricultural products and offline delivery of vegetables to their homes, which has effectively promoted the export of Guizhou goods, the online delivery of goods to the countryside, and the poverty alleviation of e-commerce. The cumulative transaction volume of the platform has reached 1.6 billion yuan, directly driving the income of more than 200,000 rural poor farmers.　

Big data helps the service industry grow rapidly.

Tourism, logistics, finance, transportation and other industries are also deepening the application of big data and promoting the integration and upgrading of these fields to platform, intelligence and sharing.

In Fuzhou Sanfang Qixiang Scenic Area, visitors can take a self-help tour through real-time VR scenes and audio guided tours. In Nanhou Street, by scanning the QR code on the tree and entering the blockchain love tree applet, photos and love declarations can be uploaded to the blockchain and permanently preserved, forming a unique blockchain love certificate, and there are interactions such as AR photo taking and AR blessing, which adds high-tech fun to the ancient lane tour.

As the guest province of this Digital China Construction Summit, the "Village-to-Village" APP exhibited in Guizhou Province is the first mobile Internet application platform in China to solve the difficulties of rural travel, students’ going home from school and freight logistics. Through the "village-to-village", villagers can book chartered cars, network cars, taxis, customized student buses, and also choose logistics services such as express delivery to the village, small express delivery, e-commerce logistics, and rural freight transportation. At present, the platform has covered 88 counties in Guizhou Province, and nearly 20 million people have enjoyed the benefits of digital life.

Big data leads the transformation and upgrading of traditional industries

As the core area of the National Big Data (Guizhou) Comprehensive Experimental Zone, Guiyang uses new generation information technologies such as cloud computing, big data, Internet of Things and artificial intelligence to upgrade traditional industries in all directions, from all angles and in the whole chain.

Hao Xu, member of the Standing Committee of Guiyang Municipal Committee and executive deputy mayor, said in an interview that integration is the biggest feature and value of big data development in the new era. In 2018, Guiyang launched the "Integration of All Enterprises" campaign to guide and promote the integration and upgrading of real economy enterprises in all fields and industries.

As a traditional food enterprise, "Laoganma" has established a big data operation center to accurately analyze and manage raw material procurement, product production and marketing, quality inspection and supervision, and improved product quality and standards. At present, 20 varieties of products have been sold to more than 70 countries and regions.

Big data has become a new business card for the whole country and the world to know Guiyang. In 2018, the main business income of big data enterprises in Guiyang exceeded 100 billion yuan, an increase of 22.4%. The contribution rate of new kinetic energy represented by big data to economic growth reached 21%, which promoted Guiyang’s industrial transformation and upgrading out of a new road of high-quality development.

The benefits of big data empowering traditional industries and the real economy are obvious. How to further promote the deep integration of big data and the real economy? Yu Shaohua, academician of China Academy of Engineering and chairman of Digital China Industry Development Alliance, believes that it is necessary to build and improve all kinds of infrastructures necessary for integrated development, because the deep integration of the two cannot be separated from the support of information infrastructure.

At the second Digital China Construction Summit, Yu Shaohua proposed to accelerate the construction of network infrastructure, accelerate the construction and deployment of industrial Internet in key areas, improve the scope and quality of data collection in various industries and fields of the real economy, and provide support for the storage and analysis of big data in various fields of the real economy.

With the digital economy taking root, a brand-new industrial ecology is taking shape, with the wings of "digital". In the future, our life will become better. 　

Before BYD Han, China brand had a good sales performance in the middle and low-grade SUV market, but it was facing a huge crisis in other market segments. Especially in the mid-to-high-end car market with a price of more than 200,000, the product supply capacity of China brand is seriously out of line with the purchasing power of consumers. When BBA sells more than 10,000 models with a price of more than 300,000 per month, China brand has little power to cope. Fortunately, the sales volume listed in July 2020 steadily broke through 10,000, and it became the exception.

, Audi 6L, the only product that achieves a stable monthly sales volume of over 10,000. It is said that since its listing, BYD Han’s cumulative sales volume has exceeded 92,000 vehicles, and it continues to lead the medium and large-scale market of China brands. On the first anniversary of listing, in order to meet the diversified needs of users, BYD Han also launched a new OTA upgrade package.

As an intelligent new energy flagship car that can be upgraded by OTA, BYD Han has been upgraded many times since its listing. However, on the evening of July 19th, the OTA upgrade of BYD Han’s first anniversary will be pushed one after another, which is also the 15th OTA upgrade of Han. Many new online functions are very interesting, such as HUAWEI HiCar, RPA’s automatic parking assistance function outside the car, and rhythmic music atmosphere lights, which can bring users a smarter and more interesting travel experience.

In order to adapt to the multi-scene parking environment, BYD Han introduced the RPA automatic parking assistance function on the basis of visual integration of automatic parking assistance system, which can help users solve the parking problems in different scenes, so as to achieve automatic parking of vehicles inside and outside the car, making parking easier and easier to operate. After all, in some extreme cases, people can better avoid risks by parking outside the car, making parking safer and ensuring the safety of users and vehicles.

With the continuous development of science and technology, the DiLink 3.0 intelligent networking system carried by BYD Han is also very user-friendly. Empowered by digital technology, DiLink 3.0 intelligent networking system has brought more intelligent human-computer interaction experience, and through continuous OTA upgrade, it has created a more "know you" intelligent cockpit. This time, BYD Han’s new HUAWEI HiCar can also realize the intelligent interconnection of people, cars and homes. Through the connection between mobile devices and cars, mobile phone applications and services can be extended to the Internet, and the mobile phone can be controlled by the car, including cool dog music, Himalayan, Alipay and other mainstream applications. In order to provide users with both auditory and visual enjoyment, BYD Han’s OTA upgrade adds rhythmic music atmosphere lights, which adds more driving pleasure and a sense of driving ceremony to car life.

All in all, BYD Han not only has the advantages of products, but also leads the industry in its persistence in technology research and development. This time, BYD Han launched the OTA upgrade package, which added a number of intelligent new functions, which not only enriched the car life of the majority of car owners, but also saved a lot of trouble for car owners when using vehicles to travel.

　　There is an online buzzword: I have walked the longest road, which is your routine. Now, it may have to be changed to: "The longest queue I have ever stood in is all for child care."

　　Especially in some tea shops, doughnut shops, Guo Kui shops and other snack bars, and even at the door of hot pot restaurants, it is often seen that there are many people waiting in line at any time, and some even have 40-50 people waiting in line. "The line is too long, and the road can’t be lined up!" People can’t help but sprout. Are these people in line really queuing? Or a fake queue?

　　Even at noon when the outdoor temperature is 39℃, there is always a long queue in front of a snack bar named "Beef Youmo" in Dakejia Lane, Chunxi Business Circle, Chengdu. From July 10 to July 12, Huaxi Dushi Bao-cover journalists chose the methods of on-site squatting, shooting videos and unannounced visits, trying to expose the truth behind them.

　　doubtful point

　　The average taste of beef oil is 7 people, and each time they buy one, they queue up repeatedly.

　　During the summer vacation, Mr. Chen from Guangdong took his children and his family of three to Chengdu to play. When passing Dakejia Lane in Chunxi Road business circle, he was attracted by a queue of more than 30 meters long in front of a snack bar named "Beef Youmo", and intuitively judged that the cakes in this store should be very delicious.

　　Walking into this small shop of about 10 square meters, two or three employees are busy in the shop. On the wall, there are all kinds of flavors of beef oil (similar to Guo Kui but with more fillings), and the prices are all in 10 yuan. If it weren’t for the long queue, this old-fashioned shop would be unremarkable at all.

　　At noon, the outdoor temperature is close to 40℃. Mr. Chen asked his wife and children to wait on the bench and queue up by themselves.

　　The reporter estimated that it was Mr. Chen’s turn to buy from 12: 50 until 1: 30. "It tastes just so-so. I don’t think it’s worth waiting in such a long line to buy food."

　　"There are still few people now, and there are more people on weekends or holidays." A man in white short sleeves shouted hard. "Bake now and sell now, come on, let’s take advantage of the fact that there are fewer people in the queue now … …” When people come in line, the lead conductor will quickly step forward, collect money, and then give customers bags to wait in line.

　　From July 10th to 11th, from 12 noon to 17: 00, reporters were on the scene for two days. There are at least 12 people in the queue, and more than 20 people, most of whom are tourists with foreign accents.

　　In the tens of meters long queue, there are also some tourists who give up queuing and leave halfway. However, during the four or five hours of squatting, the reporter found a strange phenomenon: at least seven people were waiting in line from 1 o’clock until the reporter left. These include three women traveling together, a man and a woman traveling together and two separate men. Different from other tourists, these seven people appear to be with an easy grace, unhurried, and some of them are either playing mobile phones or whispering to each other, talking and laughing. The reporter roughly estimated that the seven people had lined up at least four or five times in the whole afternoon, and even seven or eight times.

　　Their behavior and trajectory are also surprisingly consistent: queuing and buying only one. After buying it, they didn’t eat it directly, but left slowly in the direction of a large supermarket nearby. After about 10 minutes, these people returned to the queue. Then, the beef oil in their hands disappeared. The reporter noticed that these seven people will not appear in the team at the same time. Generally, three or four people will line up at a time and repeat the cycle.

　　survey

　　Two days before and after, four people all lined up to buy cakes and went to the same place.

　　The behavior of these people is full of doubts. If you buy beef oil, why not buy enough at once, but go to the queue four or five times and buy only one at a time? They left with beef oil and returned in just 10 minutes. Did they eat the food or where did they go? With these doubts, all the reporters continued to observe at the door of the store, and the other reporters followed the footsteps of these people all the way to see where they went.

　　Time: 12 noon on July 10th — twenty past five p.m.

　　The reporter first noticed four people. A man in grey short sleeves, jeans and khaki sandals. At 13: 59, he appeared in the queue, holding a paper bag in his right hand. In front of him, a trio of women appeared together, in which a tall woman wore a flowered skirt, a short-haired woman wore denim shorts and white short sleeves, and another middle-aged woman wore green short sleeves, which was very conspicuous.

　　About 20 minutes later, each of the three young women left with a beef oil, passed by the door of a large shopping mall nearby, and then entered the first city, passing through a 1-meter-wide passage next to the entrance of the parking lot of Kejia Building at No.48 Zhengkejia Lane, and then entered a small door. In less than 10 minutes, three people came out of this door empty-handed. Subsequently, the gray short-sleeved man also entered this small door. After more than 10 minutes, they appeared in the queue again.

　　From 12 noon to 5: 20 pm, the reporter found that there were at least seven people who participated in the queue for three times, most of them were gray short-sleeved men and trio, and they went back and forth at least four or five times. When the queue was the largest, there were 20 people in the queue, 7 of whom were "old faces".

　　Time: 1: 00 noon on July 11th — 4 p.m.

　　At 1 pm on July 11, the reporter went to the scene for investigation again. As the day before, there was still a long queue here. The clerk in white short sleeves who is in charge of collecting money and directing the queue is still the same shouting words.

　　Soon, the reporter found that several people who appeared the day before appeared again. In the women’s trio, the flowered skirt was replaced by a yellow striped skirt, the short-haired woman with denim shorts, and the white short sleeves were replaced by blue short sleeves, while the middle-aged woman with green short sleeves wore white short sleeves. A men’s gray short sleeves turned into dark shirts. Since 2 o’clock, these four people have walked back and forth three or four times along the route of the previous day.

　　Different from the day before, the reporter noticed that several new faces appeared. After combing the two-day investigation, nearly 10 "customers" in this store are suspected of being childcare.

　　Starting from the bottom

　　A special company organizes fake queues for 10 times a day with a monthly salary of 1,500 yuan.

　　What is the identity of these childcare, and where did they come from? In order to solve these puzzles, the reporter immediately contacted the clerk in charge of collecting money and directing the queue on the grounds of part-time job. At the scene, the clerk refused at first, saying that they didn’t need to recruit part-time jobs. It may be considered that there are too many people on the scene, and then he asked reporters to add WeChat communication first.

　　Looking through his circle of friends, in the past year, almost all of them have shown off small videos and photos of long queues in the store. For example, on July 5, he proudly said in the video: More than 30 people lined up in the rain on rainy days, too many people! For example, on May 5, there was a long queue of nearly forty or fifty people in the video. He said, "The queue is too long, and the road can’t be lined up!"

　　The reporter repeatedly asked the clerk to directly recruit himself for a part-time job, but he was rejected.

　　He said that all the people in the queue are sent by intermediary companies every day, and the store can’t directly recruit people. He added that there is a group of intermediary companies with more than 200 people who signed up at 6 o’clock the day before and only recruited the top 20 people.

　　He further explained that if he really wants to do it, he can take the reporter to see the boss of a part-time company and then enter his group. "You can ask him to arrange it for you every day."

　　In fact, it’s not just queuing that involves fraud. At first, the shop assistant asked the reporter about his height, and said that if the height and other conditions were good, singers who participated in some activities could "lip-synch".

　　The survey found that these intermediary companies are very mature. On the one hand, by recruiting a large number of part-time staff, and then "selling" in batches. Some stores that need "child care", the intermediary company is responsible for sending a batch of "child care" every day, and the price ranges from tens to hundreds of yuan. After the role "playing" is completed, we can pay the fee quickly by means of WeChat transfer, and the intermediary earns the difference for a living.

　　Vertical depth

　　Consumers Association, lawyers say: This is consumer fraud!

　　Lawyer Chen Fengfeng of Sichuan Yingji Law Firm believes that operators hire people to queue up, which means that operators use asymmetric transaction information to artificially create the phenomenon of people queuing, create an illusion that products are popular with the public and business is prosperous, and use people’s curiosity and conformity psychology to gain good reputation and benefits. Legally speaking, this is a kind of consumer fraud, that is, by covering up the real situation of commodity sales, the operator deceives consumers to mistakenly trust the quality of the commodity and consume it.

　　The reporter called the industrial and commercial complaint 12315 consumer hotline to reflect, and the staff said: it is fraudulent for snack bars to hire people to queue up to induce consumers to consume. The public should actively report such things, and whether the snack bar behavior involves illegality needs further verification.
