　　The concept of Internet hospital sprouted in 2011, and by the end of 2015, the first Internet hospital in China — — Wuzhen Internet Hospital was established. In April 2018, the General Office of the State Council issued the Opinions on Promoting the Development of "Internet+Medical Health", which put forward the concept of Internet hospital for the first time in the document, and made it clear that Internet hospitals must rely on physical medical institutions.

　　Different from the online consultation in the past — — Taking advantage of doctors’ fragmented time for consultation, it provides services of registration, payment and report inquiry. Internet hospital refers to a one-stop service platform that relies on physical hospitals, focuses on online follow-up and routine consultation, and integrates consultation, prescription, payment and drug distribution.

　　"The Internet diagnosis and treatment of Union Medical College Hospital is not the earliest, but we strive to do our best." Qin Mingwei, director of the telemedicine center of Peking Union Medical College Hospital, said that the hospital can provide follow-up services for some patients with common diseases and chronic diseases. At present, 27 departments including cardiology, endocrinology and dermatology have been opened to support in-hospital case review, online consultation, inspection and prescription.

　　Because of the epidemic, Internet diagnosis and treatment has "fired" from the small public’s field of vision to the public’s demand. According to incomplete statistics, there are now more than 1,100 Internet hospitals in China. From online consultation, appointment and registration to providing high-quality online diagnosis and treatment services, after experiencing "more doctors" and "faster prescription", how can Internet hospitals move towards "good curative effect" and "low cost", so that ordinary people can really see the disease, see it well and afford it? Obviously, there are still several unsolved problems in front of the Internet hospital.

　　1. Can it alleviate the difficulty of seeking medical treatment?

　　"Hello, Dr. Chai, I have been eating metformin, and my blood sugar is somewhat repeated. The control is not ideal. What should I do?"

　　"Your islet function is OK. You should keep taking metformin. I’ll give you another medicine to eat with."

　　"I’m quite fond of eating, including some sweets. Can I eat fruit?"

　　"You can eat some northern fruits in moderation. Diabetes still needs to be shut up, ‘ Sugarcane is not as sweet as both ends ’ If you want to be healthy, you must learn to avoid eating, which is indeed a ‘ Pain ’ The process of … …”

　　This is the scene where Chai Xiaofeng, the attending physician of endocrinology department of Peking Union Medical College Hospital, makes a follow-up visit to Mr. Bai in Jinzhong City, Shanxi Province through the network. Mr. Bai told the reporter that with the help of his family, he hung up the number of his previous doctor by using the "Peking Union Medical College Hospital" App and successfully completed the follow-up visit. "Very patient and responsible, and the advice given is very professional!"

　　How to operate the mobile phone follow-up visit? Hospital staff clicked on the "Peking Union Medical College Hospital" App to demonstrate to reporters: before the appointment time on the day of the visit, on the home page, "I" — — Check in the "consultation record". According to the registration order, the doctor initiates the consultation invitation in the form of short message, voice or video, and the patient can reply to the information or click answer to start the consultation. The whole process is easy to operate, even for elderly patients who can’t surf the Internet, they can easily complete it with the help of their families.

　　"The speed of the development of Internet medical care first depends on the development of products." Chen Qiulin, deputy director of Health Industry Development Research Center of China Academy of Social Sciences, pointed out that this is an interactive process, and product innovation and model innovation can promote system innovation.

　　"Online doctors are mostly young and middle-aged doctors, and offline clinics are still occupied by senior professors. In this way, regular follow-up patients can no longer occupy the source of offline clinics and leave the source to those patients with incurable diseases. This is also the optimal allocation of medical resources." Qin Mingwei said that 60% of the patients in Peking Union Medical College Hospital came from outside Beijing, and the online follow-up visit also greatly saved the time cost and round-trip expenses of patients.

　　"We have also opened the online and offline outpatient service conversion appointment function." According to Qin Mingwei, the patient’s condition of online follow-up is relatively stable, and there is no need for complicated medical examination or treatment. However, if the patient’s condition is found to have changed significantly and is no longer suitable for online diagnosis and treatment, he can directly arrange an appointment for an offline clinic to avoid the trouble for patients to make appointments through other channels.

　　How to get medicine in an Internet hospital? It is understood that in September last year, the Internet medical drug distribution service of Peking Union Medical College Hospital was officially launched. In order to make the express delivery arrive more accurately, the hospital selects high-quality drug delivery contractors and signs long-term cooperation agreements. National non-medical insurance patients can enjoy the "peer-to-peer" delivery service of drugs to their homes after returning to Peking Union Medical College Hospital online, and can inquire about prescriptions and medication guidance on the mobile phone client of Peking Union Medical College Hospital. If in doubt, they can also consult with Concord pharmacists online.

　　There are hundreds of millions of patients with chronic diseases in China. The diseases are incurable and have many complications, which need long-term medication and health management to control. "I saw 25 patients in the morning according to the regulations. In fact, I often saw more than 40 patients. Half of them may be unnecessary to see. " Sun Xiaodong, deputy director of the Department of Ophthalmology of Shanghai First People’s Hospital, said that 70% ~ 80% of chronic diseases can be consulted in Internet hospitals.

　　According to Lu Qingjun, director of the Office of National Health Commission Primary Telemedicine Development Guidance Center, large hospitals have the ability of technological innovation and academic leadership. After establishing an Internet hospital and forming a mature platform, they can be shared and transferred to the primary level. "In the future, I believe that all medical institutions have the opportunity and ability to use the Internet platform to carry out Internet medical care."

　　Mao Ying, dean of Huashan Hospital of Fudan University, hopes to further rationalize the relationship between public hospitals and Internet hospitals such as third-party medical institutions, and at the same time, open the scope of practice and the autonomy of subjects and prices of Internet hospitals in public hospitals. "At present, online follow-up dispensing in public hospitals is limited to ordinary clinics, and expert clinics and special needs clinics have not been liberalized."

　　"The positioning of our Internet hospital is very clear from the beginning, that is, to achieve graded diagnosis and treatment, to leave patients at the grassroots level, and to sink high-quality medical resources to the end, to send medicines to the people at the grassroots level, to standardize management, to implement education, and to minimize medical expenses." Li Guanming, deputy secretary of the Party Committee and vice president of the Second People’s Hospital of Guangdong Province, said.

　　2. Can you achieve the effect of offline diagnosis and treatment?

　　Behind the rapid development of Internet medical care is the rigid demand for people’s livelihood. In the face of Internet hospitals, many people have questions: Can remote video see the symptoms clearly? If you don’t take a film and check your blood, can you diagnose it?

　　In fact, Internet hospitals at this stage are not "cloud consultation" but "cloud follow-up". "Many patients have already seen a doctor in a physical hospital, and all the tests that should be done have been done. On the one hand, online follow-up is to understand the progress of the disease, on the other hand, it is to prescribe drugs and adjust drugs. More patients go to ‘ Cloud ’ It is to consult a doctor’s professional opinion. If further examination or surgery is needed, the doctor will inform the patient to transfer to a physical hospital for treatment. If it is impossible to see a doctor, how to deal with it temporarily. " Shu Yongqian, director of jiangsu province hospital Cancer Center, pointed out that this kind of consultation is more like the pre-examination and triage of primary medical institutions, focusing on judging the severity of patients’ symptoms, and forming a service order of graded diagnosis and treatment with offline entity hospitals. On the Internet hospital platform, you can directly return to the clinic and issue an electronic prescription to buy drugs.

　　At present, the technical means of online diagnosis and treatment are relatively mature. Internet hospitals have made great progress in mobile ward rounds, mobile nursing, full link of monitoring equipment, remote first aid, remote consultation, medical teaching, surgical robots and remote surgery.

　　In April last year, sir run run shaw hospital cooperated with Zhejiang Unicom and Huawei Company to set up a 5G Innovation Center. By sorting out more than 2.5 million electronic medical records in the hospital, it led the development of a general clinical intelligent decision-making system, and built a medical knowledge map covering more than 600,000 ontological logical logical associations. Based on the current medical knowledge base and reasoning model, this AI reasoning engine can infer and push the symptoms, signs, medical history and examination results of patients with an accuracy rate of 90%.

　　"Now there are no technical problems in the development of Internet hospitals. The real bottleneck is how doctors really devote themselves to Internet hospitals. Internet hospitals are not ‘ Light consultation ’ Upgrade and revision. " Zhang Qiang, a well-known vascular surgery expert, suggested the establishment of internet diagnosis and treatment, from fragmented services to exclusive customized services, from no standard to full quality control.

　　Cui Yong, vice president of the China-Japan Friendship Hospital, said: "To ensure a high degree of consistency between online and offline, this also puts high demands on doctors. It is necessary to learn to use Internet technology to carry out diagnosis and treatment. " In this regard, Zhao Chengsong suggested that doctors should be trained on the Internet to improve their online diagnosis and communication skills. "Internet medical care is not exclusive to young doctors. Experienced experts should take the lead in embracing the Internet so that more patients can enjoy quality medical resources." Zhao Chengsong said.

　　National Health Commission explicitly requested that Internet diagnosis and treatment activities should not be carried out for the first-time patients, which was based on medical safety considerations. In the future, which projects can be "tested" for initial diagnosis?

　　Cui Yong believes that we can "test the water" from the field of skin diseases. "Most skin diseases can get good diagnostic information through naked eyes or simple equipment (such as dermatoscope). At present, ‘ Skin image application framework network ’ It can also achieve information exchange well and can be used for telemedicine and Internet diagnosis and treatment. " Cui Yong said.

　　"In the future, diseases that can be accurately diagnosed through intuitive information collection may be considered for online initial diagnosis." Cui Yong pointed out, however, critical illness and incurable diseases are definitely not suitable for online initial diagnosis, and diseases that need to be examined and tested generally need to go to medical institutions or third-party service institutions (provided that a mutual recognition system for examination and test results is established).

　　In this regard, Yuan Li, director of the wuhan union hospital Clinic Office, also agreed. She said that online consultation and offline consultation are not a substitute, but more are extended services before and after the hospital to reduce the economic and time burden of patients and timely inform patients of the most authoritative and most suitable popular science knowledge. At present, online consultation in wuhan union hospital is divided into two categories: health consultation and follow-up consultation. Doctors will give corresponding suggestions according to the information provided by patients, but the diagnosis, diagnosis and treatment of diseases still need offline consultation and examination.

　　3. Can online medical insurance settlement be popularized?

　　0.02 seconds to extract historical medication information, and 2 minutes to complete identity verification and medical insurance binding … … In April last year, Shandong Province’s Internet medical insurance big health service platform was launched, and key links such as medical insurance certification, follow-up check-up, online prescription, and drug delivery to home were seamlessly connected. Shandong became the first province in China to fully open and support online medical insurance settlement for Internet diagnosis and treatment.

　　Mr. Zhang from lanshan district, Linyi City became the first beneficiary. "As long as in ‘ Shandong Medical Insurance Great Health ’ After completing the medical insurance identity verification and medical insurance binding in WeChat official account, you can use medical insurance payment by choosing an Internet hospital for treatment. " Mr. Zhang is 54 years old and suffers from coronary heart disease. He usually needs to make regular follow-up visits to get medicine. "It’s so convenient now! Seeing a doctor at home can also be settled by medical insurance and delivered to the door. "

　　According to incomplete statistics, since 2015, the state and local governments have issued more than 100 policies and regulations on Internet medical care, which have gradually covered "medical — Medicine — Risk "field. In response to the issue of medical insurance reimbursement in Internet hospitals, the relevant person in charge of the National Medical Insurance Bureau said that it will improve the price formation mechanism of "Internet+medical care" services, adhere to the basic principle of reasonable price comparison between online and offline similar services, incorporate medical expenses into medical insurance, and implement online direct settlement.

　　"The insured person is designated in this overall planning area ‘ Internet plus & rsquo; The medical and drug expenses incurred by the prescription issued by the medical service follow-up visit can be paid according to the existing treatment policy of offline medical insurance. With the prescription of designated medical institutions, you can also take medicine at local designated pharmacies. " Xiong Xianjun, director of the Medical Service Management Department of the National Medical Insurance Bureau, said.

　　Lu Qingjun believes that the "internet plus" medical insurance payment policy clarifies that the "internet plus" medical service is included in the specific content of medical insurance payment, online and offline medical services are treated fairly, and priority is given to ensuring the demand for follow-up visits for chronic diseases and special diseases, and supporting the circulation of purchased prescriptions, which not only facilitates patients, but also reduces the pressure on hospitals.

　　"Internet hospitals need links of various elements. Under the premise of high-quality diagnosis and treatment services, medical services, medicines, insurance, etc., the real Internet diagnosis and treatment will appear in the cooperation and exploration between doctors and third parties. With the enhancement of patients’ willingness to pay at their own expense and the intervention of commercial insurance, Internet hospitals will have a stronger ‘ Vitality ’ 。” Zhang Qiang said.

　　Although Internet hospitals provide many conveniences for patients to seek medical treatment, the difficulty of supervision has also become a major pain point that hinders its development. The reporter noted that the third-party Internet hospital platform is characterized by "e-commerce", and the use of traffic to sell drugs has become a common model, and Internet hospitals have become Internet medicine.

　　Yinchuan is the "pioneer area" of Internet medical exploration in China. During the two sessions this year, Commissioner Ma Xiuzhen, director of Ningxia Health and Health Commission, pointed out in his proposal that drug sales revenue is an important source of profit for some commercial Internet hospitals. Due to the lack of motivation to supervise over-medication, doctors may be encouraged to prescribe more drugs, or even collude with pharmaceutical companies to promote online drug sales, leading to over-medication. At present, the regulatory authorities have not yet established a regulatory system for excessive drug use for online diagnosis and treatment, and violations have an upward trend. Therefore, it is suggested to implement "separation of medicine" online.

　　To this end, Chen Qiulin reminded that in the future, the Internet hospital supervision platform should dynamically monitor online diagnosis and treatment services, and carry out medical technology evaluation and health economics evaluation, especially for services to be included in medical insurance payment, it should monitor the changing trend of online and offline medical care and analyze its substitution and complementarity.

　　 　 　(Reporter Cui Xingyi)

Let’s take a look at its appearance first. In terms of appearance, the Jietu family style is adopted. The air intake grille on the front face is very sharp, and the headlights on both sides are quite sharp. After the headlights are lit, they look very energetic.

In addition to the above description, we can also go to the Easy Car Forum to browse more real car feedback from actual buyers, or use our experience.

　　[car home Technology] After driving for a certain mileage, vehicles often have slightly different driving feelings from new cars, and the reason for this is ultimately attributed to the components that make up the vehicle. Therefore, we have done such a thing, completely disassembling a family car that has traveled 100,000 kilometers in a short time, which is the first time for us.

　　Because it is the first time to make such a topic, we found many problems in the planning process, which may lead to the failure of the dismantling project, such as the dismantling site, vehicles used for dismantling and related technical support. Therefore, we finally decided to cooperate with automobile manufacturers. After a long period of communication, Dongfeng Nissan Qichen accepted our proposal.

● Why choose a car that travels 100,000 kilometers for disassembly?

　　The reason why the mileage of 100,000 kilometers is selected is because when a car travels more than 100,000 kilometers, some faults and problems will gradually emerge, which has little to do with the brand and price of the vehicle, that is to say, even millions of high-end brand vehicles may have various problems.

　　By disassembling a vehicle traveling 100,000 kilometers (disassembling it to the most basic component level, such as a bolt or a bearing), we can tell you which components will wear, especially the chassis system and powertrain system, which are normal and which are abnormal, and how these wear will be related to the final vehicle performance. In this process, we will also tell you how to reduce this unnecessary wear in daily use.

●　Which car to dismantle?

　　Initially, we had several basic requirements for vehicle selection:

　　1. The longer the mileage is on the basis of 100,000 kilometers, the better;
　　2. The vehicle has not been modified in power and performance, and it is all set by the original factory;
　　3. The vehicle has not had any accidents;
　　4. The vehicle is the original paint;
　　5. The vehicle is normally maintained in the 4S shop according to the regulations.

　　The vehicle has not been modified and has not had an accident. At the same time, these conditions are maintained normally, and some interference factors are eliminated as much as possible. Only in this way can the contents presented by disassembly be more representative. Based on the above points, (click for details) we have collected vehicles in the forum. In addition, you may also see the collection information of vehicles in the 4S shop. After screening, a Qichen D50 was finally locked.

● Ran 100 thousand kilometers a year!

　　The Qichen D50 we chose has a mileage of more than 100,000 kilometers in more than one year, and the average daily mileage is more than 300 kilometers. We only know the reason by asking the owner. Because of business needs, car owners often drive back and forth between cities in the Pearl River Delta region. Most of the roads they drive are high-speed and relatively smooth national roads, while the rest are relatively congested and complicated urban roads.

● Where shall we open it?

　　Such disassembly requires the cooperation of the site and relevant personnel. At the same time, we also hope to send the vehicle to a professional institution for testing and verify the state of the vehicle through the test data. Based on the above demand, we transported the vehicle to Dongfeng Nissan Factory in Xiangyang City, Hubei Province for disassembly. It is worth mentioning that it can also be borrowed from the professional test site in the factory to evaluate the vehicle subjectively.

●　Basic information of the vehicle

　　This Qichen D50 was produced in April 2012, and the specific model is the 2012 1.6L manual comfort version. The owner bought this car in June last year. After buying a car, the owner first installed an electric rearview mirror in the 4S shop (it is indeed a very practical configuration, and the manufacturer seems to realize this, which became the standard of the whole department on the 2013 Qichen D50), an anti-theft device, a leather seat and a reversing radar. We found a slight crack at the adjusting button of the electric rearview mirror, which may be caused by the later installation.

　　For more than a year, the owner carried out routine maintenance in the 4S shop according to the provisions of the maintenance manual. At the same time, during the use process, the owner himself felt that there was abnormal noise at the position of the generator and the front shock absorber. After going to the 4S shop for inspection and maintenance, he finally replaced the generator and the right front shock absorber free of charge through the claim procedure. In addition, before lifting the new car, the engine harness was damaged due to the storage problem of the car, so the engine harness was also replaced.

● Owner’s evaluation of the car　

　　In more than a year’s use, the owner is satisfied with the overall performance of the car, and there has never been any breakdown on the way to and from the city. Because it is located in the high humidity and high heat environment in the south, the owner turns on the air conditioner every time he gets on the bus. According to the road conditions explained earlier, the fuel consumption is more than 6 liters per 100 kilometers, and the owner is quite satisfied with this fuel consumption. The owner also thinks that the noise of the engine of the car is relatively small and the gear is very clear. In addition, the owner is also very satisfied with the space performance of the car and the cooling effect of the air conditioner. As for the shortage, the owner thinks that the interior of Qichen D50 is too simple, and I think this is also a compromise that has to be made from the perspective of cost control.

● Editor’s subjective driving experience (static+dynamic evaluation)

　　The vehicle has been explained clearly, and after listening to the owner’s feelings about the car, let’s make a subjective evaluation. Let’s see what changes will happen to the vehicle driving 100,000 kilometers from the most intuitive feeling. To this end,We found a 2013 1.6L manual deluxe version of Qichen D50 (hereinafter referred to as the new car) with a mileage of only over 2,000 kilometers for comparison, thusFeel the difference and difference more obviously.

-Good appearance and interior color.

　　　Perhaps it is because of the relatively short service life and the care of the owner. In short, it is difficult for us to associate this car with driving 100,000 kilometers through static observation. Its appearance and interior color are good, and all functions of the vehicle are normal.

-Abnormal sound may come from generator pulley bearing.

　　After landing, under the condition of quiet external environment, there was abnormal noise coming from the pulley side of the engine crankshaft, and it was preliminarily judged that it came from the pulley bearing of the generator. If this is the case, it can be seen that the generator assembly replaced by claim has the same problem again. But whether the abnormal sound comes from here or not, we have to wait until the disassembly to find the real answer.

　-There is slight abnormal sound at the stop bar.

　　We found that this old car will have a slight abnormal noise when it is in gear, but it will not affect the clarity of gear and the feel of shifting. We feel that this abnormal noise is probably caused by the lack of adequate lubrication of the gear selection mechanism. In the later disassembly, we will further confirm the cause of the problem.

-The noise of the old car is slightly louder than that of the new one.

　　In terms of noise, we selected two points: idle speed and 80km/h (the engine speed is about 2000rpm after the manual gear D50 is engaged in the fifth gear at this speed) to compare and test the new car and the old car. From the results, the new car is better than the old car with a mileage of 100 thousand kilometers, but the advantage is relatively small, especially when idling, the abnormal noise from the pulley of the old car leads to the obvious noise of the old car in idling. In fact, the increase of noise is an unavoidable problem for any vehicle, because the rubber and related materials that play a role in sealing and sound insulation will age to a certain extent with the passage of time, which will lead to the noise can enter, thus making the noise of vehicles rise slightly.

-The dynamic performance of the old car is better than that of the new car before the running-in period.

　　In addition, we entrust a third-party testing organization to test the dynamic performance of two Qichen (one new and one old) (the tires are all new tires of the same brand and series). Judging from the final results, the dynamic performance of the old car that has traveled for 100,000 kilometers is better than that of the new car, and it is not unusual to see this situation. After all, the new car is still in the running-in period, and the power and chassis system have not yet reached the best running-in state. In addition, although the old car has been fully run-in, there will be a certain degree of attenuation in the power system, but the attenuation of this car is not obvious because of its good driving condition, which can also be confirmed by the disassembly of the engine and transmission of the old car in our later period.

-the new car is tighter and the old car is slightly loose.

　　In terms of actual driving experience, we choose to carry out it in a closed test site, where there are many different roads that can simulate the bumps, twists, speed bumps, asphalt roads, stone roads and gravel roads that vehicles may encounter when driving on actual roads.

　　By comparing the test drive of two vehicles, the first obvious feeling is that the new car is more compact and complete, while the old car is slightly loose. When passing through cobblestone sections, the interior parts of the two cars will have obvious abnormal noise, while the old car is more prominent. I think this may be related to the deformation of the plastic parts in the car after a certain period of use and the change of assembly clearance.

　　When I was driving at a speed of about 20km/h on a twisted road with ups and downs, I could obviously feel that the potential energy of the spring could not be reduced and absorbed quickly because of the performance attenuation of the shock absorber in the old car, which made the body bounce relatively greatly, while the body bounce of the new car was smaller. Based on this, we have to dismantle the shock absorber destructively in the later stage to see what happened inside the shock absorber, and please pay attention to our subsequent disassembly report.

Summary:

　　Through subjective driving experience, we have a preliminary understanding of the basic situation of the vehicle. In terms of appearance, interior and various functions of the vehicle, the vehicle has maintained a relatively new level. However, after all, I have already traveled 100,000 kilometers, and I immediately felt the obvious difference through driving. We have also recorded some good or bad situations found, and we will find the corresponding answers for everyone in the later disassembly. (Text/car home Feng Jingyi)

Next notice:

　　At the beginning of this topic, this paper mainly explains the daily use of this vehicle which has traveled for 100,000 kilometers. In addition, we will also analyze the subjective evaluation of static and dynamic driving, and find the answer to the question through detailed disassembly in the later period.

　　[car home Technology] With the increase of mileage, the aging characteristics of vehicles are becoming more and more obvious. For drivers, abnormal noise is the most intuitive category. As mentioned in our previous article, the owner judges that there may be some problems in the vehicle based on abnormal noise, and the subsequent inspection results also confirm the reliability of this intuition, and those silent changes are also taking place. We ended them when the odometer of Qichen D50 entered the 100,000-kilometer mark. This article will show you the situation of the body and chassis.

　　If you don’t know what we are doing, it is necessary for you to know the contents of the first stage, such as why we are doing this, how we choose the car, and of course, the general situation of disassembling the car is also very important. (Click for details)

The second stage: body disassembly

　　Don’t underestimate the structure of this energy-absorbing box. Through literal understanding, we know that its function is to absorb collision energy by virtue of its own deformation in the event of collision, so as to reduce the impact on the back.

　　It’s easy to say, but it needs careful design to achieve better energy absorption effect. On the one hand, the wrinkle design on its surface divides the energy absorption process of the energy absorption box into three parts, which makes the energy absorption process of each part relatively independent and stable, and the position and amplitude of these two folds are obviously calculated through a lot of calculations. In addition, the energy-absorbing box connected by bolts can effectively control the maintenance cost.

　　In the energy-absorbing box, different cars have different structures, some cars are not equipped with energy-absorbing boxes, some cars are equipped with energy-absorbing boxes but have no wrinkle design. In addition, there is a difference in the connection mode of energy-absorbing boxes. Some cars’ energy-absorbing boxes are connected with anti-collision beams and longitudinal beams by welding.

☆ Door disassembly

Further disassembly in the car

　　The next step is to disassemble the car body further. In the end, what we see is just a car body, just like the car body we see in the painting workshop every time we visit the factory. Although it is impossible for us to judge the anti-corrosion ability of the car body by using it for more than one year, when it is "naked" in front of us, we can clearly see the structure of the car body and the workmanship inside and outside. This is also a very noteworthy link.

☆ Passenger compartment structure

　　As we all know, the coating process carried out in the vehicle manufacturing process can ensure the corrosion resistance of the car body. As long as the paint surface of the car body is not damaged in the later use of the car, in general, the car body steel plate can be guaranteed not to be rusted in 10 years. Of course, the process of the steel plate itself is also very important. We learned from the manufacturer that the Qichen D50 uses galvanized steel plate with good corrosion resistance, which also ensures the aging resistance of the car body to a certain extent.

☆ Details of the cover

☆ The mystery of pedal

　　As we expected, there are no signs of years such as rust or dim color on the surface of the car body. For such a car with a driving time of about one year, it is really difficult to judge its anti-corrosion performance, but in any case, we can still gain something in the process of disassembling the car body, such as the materials and structure of the car body.

The third stage: chassis disassembly

　　According to our previous experience of comparing the test drive of new and old models, Qichen, which has traveled for 10,000 kilometers, did show some fatigue in the chassis link. For example, after passing through the ditch and ridge road for many times in a row, the vibration absorber’s ability to restrain the body shaking has declined, and we hope to find the answer in the subsequent disassembly.

● Suspension disassembly

● Front suspension disassembly

　　The front suspension structure of Qichen D50 is McPherson-style, and the process of detaching it from the car body together with the subframe is not complicated. The subframe and the car body are connected by four bolts, but before loosening them, we need to disconnect the connection between the damping strut and the car body and the engine support elements, and then the suspension assembly and the engine are detached together. Next, we will analyze the suspension disassembly, and the engine disassembly will be arranged at the end.

☆ steering rod ball

　　Under normal circumstances, the car that has traveled for 100,000 kilometers is prone to problems, which is the abnormal sound or looseness caused by the aging of the rubber parts of the chassis. The ball head of the steering rod is a part that is prone to problems. The ball head of the steering rod is responsible for connecting the steering rod and the steering knuckle. Besides the ball head, there is lubricating oil in it. Once the rubber sleeve outside is damaged due to aging, on the one hand, the lubricating oil will leak out; on the other hand, dust, dirt and rain may also enter the ball head, which will accelerate the wear of the ball head, and then the damping force on the swing of the ball head will become smaller, and its interior will begin to wear and gradually become loose.

　　For the driver, it may be felt that the virtual position of the steering wheel is getting bigger (loose and spacious, which can be felt by shaking the wheels with both hands after lifting the car). On the other hand, it will also affect the stability of the vehicle when it is dynamic to some extent. From the disassembly of Qichen D50, we can see that the steering rod ball head is in good condition, and the steering wheel is not found to be too empty during the previous test drive, so it can be judged that there is no problem in this part. However, the aging of rubber covers is also related to time, which generally does not happen when the car is used for more than one year.

☆ Steering knuckle and bearing

● Rear suspension disassembly

　　The rear suspension of Qichen D50 adopts the longitudinal arm torsion beam structure, and the simple structure is the advantage of this kind of suspension structure, especially for compact cars like Qichen D50, it is particularly important to contribute more space to the interior of the car.

● Brake pad wear

● Disassemble shock absorber

　　The situation that the body sway can not be suppressed as soon as possible is mostly directly related to the shock absorber. With the increase of mileage, its performance will gradually decline. In addition, continuous and high-intensity work will also reduce its performance.

　　Before disassembling, we made a static comparison of the height of the car body. In the case of no load, there was no obvious difference between the heights of the old and new cars, which to some extent showed that there was no big problem with the springs supporting the height of the car body. Next, we will further disassemble the shock absorber strut and shock absorber.

　　This kind of shock absorber with double-tube structure is widely used in ordinary household cars. After many times of intensive work, the hydraulic oil and air inside may be mixed together, which will lead to a large number of bubbles in the hydraulic oil. In this state, the performance of the hydraulic oil is bound to be greatly affected. This may be the reason why the car body shaking in Qichen D50 cannot be suppressed as soon as possible. The above is only our theoretical analysis according to the structure.

● Vibration isolation state between spring and car body

● Abnormal wear of tires

☆ Wear difference between front and rear tires

　　When cleaning up the workshop, we accidentally found that the removed tires showed signs of abnormal wear. Usually, this is related to the four-wheel alignment of the vehicle and daily use.

　　According to our understanding, the tires of this Qichen D50 have not been changed during the driving period of 100,000 kilometers. Only during the maintenance period, the maintenance technician found that the wear of the front and rear tires was obviously different, and the front and rear tires were switched. However, we can still see some clues from the wear of the tire surface.

　　For most (engine-front) vehicles, because the center of gravity of the vehicle is relatively forward, the pressure on the front tire is greater. According to the physical definition, the friction between the tire and the ground is greater when the contact area is fixed. In contrast, the wear of the front tire is more serious than that of the rear tire.

　　From this point of view, it is very necessary for us to switch the front and rear tires regularly during our daily car use, which can make the wear state of the front and rear tires more uniform, thus delaying the service life of the tires. Specifically, the front-back exchange or diagonal exchange can be adopted, but if the tire has a rolling direction mark, then the same side can only be used for the front-back exchange when the tire is transposed. This requires special attention.

☆ Eccentric wear of tires

　　In addition to the difference between the front and rear tires, the tires used as front wheels for a long time have eccentric wear. From the tire surface, the degree of wear on the outer side is more serious.

　　This may be a problem with the four-wheel alignment of the vehicle, but it may also be caused by the tire being in a state of insufficient air pressure for a long time. Modern cars tend to set camber to a negative value to improve the driving stability of the vehicle. If the tire is in a state of insufficient air pressure, it will aggravate the wear on the outside of the tire when the vehicle turns.

Editor’s summary:

　　The Qichen D50, with a mileage of over 100,000 kilometers, shows no obvious signs of aging in the body and chassis. Among them, because the service life of the vehicle is about 1 year, and under normal circumstances, the painting process can ensure that the car body will not be rusted for 10 years, so it is difficult to fully show the anti-corrosion state of the car body. In addition, in the chassis link, we focused on the problem of vehicle body sloshing after passing through the ditch and ridge. Through structural analysis, after many bumps, the mixing of oil and gas in the shock absorber may be the chief culprit leading to damping attenuation. No signs of aging were found in the rubber bushings between the various connectors of the chassis. On the one hand, the quality of the components themselves was excellent, on the other hand, it was related to driving habits and car use time. In the next article, we will disassemble the powertrain. Compared with the body and chassis, the driving of 100,000 kilometers is a greater test for this part. (Photo/Text car home Li Boxu)

　　[car home Technology] In the first two issues, we made a subjective evaluation of a Qichen D50 that has traveled for 100,000 kilometers, and tried to find out the possible changes of the chassis system and the body through disassembly. In this article, we will disassemble the core powertrain in detail to see what changes it will have after 100,000 kilometers of operation.

　　If you don’t know what we are doing, it is necessary for you to understand the contents of the previous stages, such as why we should do this, how we choose the car, and the disassembly of the body and chassis.

The fourth stage: engine disassembly

● Find the source of abnormal noise on one side of the engine pulley.

　　First of all, we have to remove the generator, air conditioning compressor and other accessories from the engine. We turned the pulley of the removed generator by hand, but we didn’t find the abnormal sound we heard in the subjective evaluation before. It can be seen that the abnormal sound didn’t come from this, and finally it was determined that the root cause was the tensioner.

　　Generally, the design concept of Japanese manufacturers is to achieve the initial requirements through the simplest structure as possible, so the design similar to Qichen, which is adjusted by screws, can automatically adjust the tightness of the belt according to the tightness of the belt, although it is not like the automatic tightening wheel designed by German manufacturers, but its advantage lies in its durability.

　　Although the belt connecting the engine accessories is not like the timing belt (most vehicles use timing chain nowadays), once it breaks, the intake and exhaust valves of the engine will be seriously damaged, but it also needs to be checked daily. If it strikes, the generator will not work and the vehicle will break down.

● Cooling circulation system

● clutch

● Wear of crank-connecting rod mechanism and valve timing mechanism

　　Both crank-connecting rod mechanism and valve timing structure run well after 100 thousand kilometers. Although you can clearly see the friction marks, they are all normal phenomena. This is not only due to the manufacturing accuracy, but also due to the engine oil, and changing the engine oil regularly is the best protection for these metal parts that are always in a harsh environment.

●　Variable valve timing system with high requirements for oil cleanliness

● Carbon deposition in injector and piston

● Carbon deposition in intake and exhaust systems

　　Although we often mention the word "carbon deposit", it will still be incredible when we see these things strongly attached to the relevant parts of the engine. Indeed, no matter how good the oil, car habits, car environment and other conditions are, carbon deposition is always inevitable, but some cars are more serious and some cars are less serious. For example, it is easier to form carbon deposition when driving on congested roads in cities, and once it is formed, it is difficult to completely remove it.

Stage 5: Disassembly of manual transmission

　　For friends who don’t know much about the structure of manual transmission, it is strongly recommended to click on the article "Manual transmission you don’t know: the mystery under the shift lever" to learn.

Full text summary:

　　After 100 thousand kilometers, the powertrain system is still in good condition, especially the degree of wear is low, so the importance of regular maintenance is self-evident. However, the generation of carbon deposit is inevitable. When it is serious, it will have a great impact on fuel consumption and power. If you want to completely remove it, you must completely disassemble the engine to solve it.

　　At this point, our topic of "100,000-kilometer vehicle dismantling" is over. Through dismantling, we show you what changes will happen to a vehicle that travels 100,000 kilometers, so as to help you develop good driving habits and strengthen the daily inspection and maintenance of the vehicle. As the saying goes, "three-point repair and seven-point maintenance", only in this way can we better enjoy the life of owning a car. (Text/car home Feng Jingyi)

　　Cctv news(Focus Interview): Speaking of big data, everyone is no stranger. At present, online shopping, mobile payment, smart transportation, epidemic prevention and control are all inseparable from the support of big data, which has been integrated into all aspects of our lives. There is a metaphor that data is the oil of the Internet economy. On May 28th, 2021 China International Big Data Industry Expo ended in Guiyang. The Expo was founded in 2015 and officially upgraded to a national-level Expo in 2017. Now it has become the vane of big data development and an international and professional platform. So what are the new features, new achievements and new applications of this year’s Digital Expo?

　　This year’s Digital Expo will focus on the "change" and "new" brought by big data with the theme of "changing intelligence and bringing new things". Due to the need of epidemic prevention and control, this year’s Expo has adopted the "online+offline" exhibition mode. The 40,000-square-meter offline exhibition area includes four theme pavilions, namely, the Frontier Technology Pavilion, the Smart Industry Pavilion, the International Complex Pavilion and the Digital Application Pavilion, to showcase new technologies, new products, new solutions and new applications of big data and the changes that big data has brought to people’s lives.

　　For exhibitors who can’t make it to the site, they can display their brand features and star exhibits with videos, pictures, documents and other information through the online display platform, and communicate with guests and professionals from all over the world online. The offline audience adopts the reservation system and visits at different peaks.

　　In the artificial intelligence exhibition area of the Expo, all kinds of robots are very attractive. The 5G remote ultrasonic robot can complete the whole process of remote ultrasonic diagnosis, and the new infrastructure, smart future and new experience based on 5G network have also become the focus of attention. The technology company exhibited a helmet monitoring system based on 5G network, artificial intelligence and big data technology. As long as you enter the designated area, the system will automatically identify whether you are wearing a safety helmet and give an early warning.

　　New products and applications of big data have also become more accessible in life. In the Smart Industry Pavilion, the smart system of an enterprise can collect the physical signs data of human body during sleep for a long time, process and analyze the data, and give personal health guidance programs. At present, this enterprise has cooperated with some old-age care institutions to explore a new model of smart old-age care.

　　With the empowerment of big data, cities become smarter. In this year’s Digital Application Pavilion of Digital Expo, this exhibitor from Shanghai brought new applications of big data. On this system, big data technology focuses on the key areas of Shanghai’s urban management and operation. The establishment of intelligent model can comprehensively monitor the overall state of urban water supply system, and send out warnings and reminders in time when problems are found.

　　In addition to the water system, the brain of the city has begun to predict in advance the fields of transportation, fire safety and smart parking.

　　Guizhou, the host of the Expo, is an important pioneer area for China to implement the big data strategy. Since the establishment of the National Big Data Comprehensive Experimental Zone in Guizhou in 2016, new achievements have emerged in the development and application of big data in the fields of economy, society and people’s livelihood. At this year’s Expo, the digital government work platform was displayed in the exhibition hall of Guizhou on the Cloud, which broke the data barrier and brought new changes to people’s lives through data exchange and sharing among different departments. At present, in the mobile terminal run by Guizhou Netcom, the government service functions of different departments are classified together.

　　The technical application of the smooth flow of data not only makes people run less wrong roads, but also shows their talents in consolidating the achievements of poverty alleviation. Heiyan Village, jiangkou county, Tongren City, used to be a second-class poverty-stricken village, but now it has been lifted out of poverty. Some time ago, Guizhou Poverty Alleviation Cloud Big Data System sent monitoring and early warning information to Heiyan Village: More than half a month ago, a villager named Long had heart surgery in the Municipal People’s Hospital, and the village cadres needed to verify the situation as soon as possible. In the morning, the poverty alleviation cadres came to the villager’s home.

　　After confirming that the medical expenses and other related expenses did not pose a risk of returning to poverty for this family, Hu Yinxi logged the verification results into Guizhou Poverty Alleviation Cloud System.

　　Such a big data monitoring system has strict authority settings and shields personal sensitive information, mainly monitoring the data of unexpected situations that have the risk of returning to poverty in production and life. At present, Guizhou Province has included groups such as unstable poverty-stricken households and marginal households in the scope of big data monitoring. If there is a risk of returning to poverty or causing poverty, it will accurately analyze the reasons and eliminate the risks through effective measures.

　　This year is a crucial year for consolidating and expanding the achievements of poverty alleviation and effectively connecting with rural revitalization. After several years of development, big data technology has been applied in rural revitalization. Therefore, this year’s Digital Expo has also set up a section called "Big Data Helps Rural Revitalization". From the aspects of big data and rural environmental governance, rural e-commerce, tourism and agricultural industry integration, we will demonstrate and explore big data to empower rural revitalization.

　　The key to rural revitalization is to do a good job in industry. The "pepper cloud" on display at a booth caught the attention of reporters. On the "Pepper Cloud" platform, the data of the whole industrial chain, such as planting process, agricultural science and technology, meteorology, soil, humidity, landform and detection, are integrated, and big data technology is used to promote standardization for scattered farmers.

　　The "Pepper Cloud" platform, which breaks the problem of data collection and promotes standardized planting, relies on smart phones and big data model algorithms to insert wisdom wings for small peppers in mountainous areas. In Taiping Village, Zheng ‘an County, Guizhou Province, the 500-acre pepper planted by villager Wan Hong grew well, but weeds grew in the field and the pepper branches grew to the length of pruning. Wanhong, who was at home at this time, received a reminder from the agronomist on the platform on her mobile phone.

　　In a short time, in addition to a large area of weeding in wanhong’s pepper field, he quickly took out his mobile phone and took a few photos of the on-site completion and uploaded them to the "cloud platform" of the mobile phone.

　　On the "Chili Cloud" platform, whether the work is qualified or not is calculated by the data brain.

　　In addition to showing the latest applications of various innovative technologies based on big data in economic and social fields, the number fair has also become a new platform for the competition and development of innovative technologies. At this Expo, the announcement of the results of the selection of leading scientific and technological achievements awards attracted much attention. Among the 49 award-winning projects finally selected, seven projects including the research and application of bus-level data center network technology won the Black Science and Technology Award.

　　"The number of wisdom changes, and things are new." After seven years of development, the Expo has not only become a platform for the display and exchange of innovative technologies, but also built a bridge for the integration of China’s big data industry with the world and become an important platform for attracting foreign investment.

　　Big data has been widely used in China’s economic and social development, and the pattern of rapid development of big data industry has basically taken shape, but it still faces many challenges in data open sharing, core technology breakthrough and big data-driven development. The Expo provides a platform for innovation, integration and communication to meet these challenges. For the development of big data that has become a national strategy, activating, mining and applying big data and exploring more new technologies, new formats and new models can generate greater value and empower high-quality development.

　　Overseas Network September 10th US media reported that Ireland’s data regulator has issued a preliminary order to Facebook, asking the other party to stop transmitting relevant data of EU users to the United States.

　　According to a report quoted by the US Consumer News and Business Channel (CNBC) on the 10th, the preliminary order was issued to Facebook by the Irish Data Protection Committee (DPC) in August. Nick Clegg, Facebook’s vice president of global affairs and communications, pointed out in a blog post published on Wednesday (9th) that DPC has started to investigate Facebook’s data transmission in the European Union and the United States.

　　The report was released a few months after the European Court of Justice ruled that the data transmission standards between the EU and the United States could not fully protect the privacy of European citizens. The European Court of Justice (ECJ) is the highest legal institution in the European Union. After determining that EU citizens have no effective way to counter the monitoring of the US government, the court restricted American companies from sending European user data to the United States. Theoretically, American institutions such as the National Security Agency (NSA) can ask Internet companies such as Facebook and Google to hand over data about EU citizens, while EU citizens are kept in the dark.

　　The European Court’s ruling came after Schrems, an Austrian privacy activist, filed a lawsuit based on a disclosure by Edward Snowden, who claimed that American law did not provide sufficient protection against surveillance by public authorities. Schrems filed a complaint against Facebook, which, like many other companies, is transmitting data of Schrems and other users to the US government.

　　The court ruling invalidated the EU-US privacy protection agreement, which had enabled these American Internet companies to transmit data of EU citizens across the Atlantic. After the verdict, these American Internet companies began to rely on standard contract terms (SCC) to transmit data.

　　Clegg, former British Deputy Prime Minister, said that the Irish Data Protection Committee had begun to investigate the data transmission in Europe and America controlled by Facebook, and suggested that SCC should not be used for data transmission in Europe and America in practice. If SCC cannot be used as the legal basis for data transmission, Facebook will have to cancel most of the data collected by European users. DPC may impose a fine of 4% of Facebook’s maximum annual income, or if it fails to comply with the ban, it will be fined 2.8 billion US dollars (about 19.14 billion yuan).

　　Although the order applies to Facebook, DPC may issue similar orders to other American technology giants, which may cause serious damage to its business. Clegg went on to point out that the primary task of the EU is to ensure that users, advertisers, customers and partners in Europe can continue to enjoy Facebook services while maintaining the security of their data, and that European countries will continue to transmit data in accordance with the recent ruling of the European Court of Justice until further guidance is received. He also warned that companies need to abide by clear global rules to protect transatlantic data flows for a long time. (Overseas network Hou Xingchuan)

Topic: Israeli bombing of Gaza Strip.

　　Experts say "the seventh Middle East War" is unlikely to break out.

　　Shang Bin, a special correspondent of Global Times, reported that in recent days, the situation in the Middle East has suddenly become tense with the intensive Israeli air strikes on the Gaza Strip. On the 29th, Israeli Defense Minister Barak said that his country was waging an "all-out war" against Palestinian militant group Hamas and its leaders.

　　On the 30th, an Israeli spokeswoman declared to the outside world that her country was ready to launch a ground offensive against Gaza. In the face of Israel’s fierce offensive, Hamas also declared that it would launch a "third uprising" to defeat the Israeli regime. Will the Middle East, which has been baptized by war, fall into a tragic war again? Will the development of the situation lead to the outbreak of the "Seventh Middle East War"? In this regard, the Global Times reporter interviewed several scholars on Middle East issues, and they all agreed that there is little possibility of another Middle East war.

　　Gao Zugui, an associate researcher at China Institute of Contemporary International Relations, said that this time, Israel launched an "all-out war" against the Palestinian militant group Hamas, not against the whole of Palestine. More importantly, Abbas, president of the Palestinian National Authority, who can represent Palestine internationally, has "exercised restraint" and does not want the conflict to escalate. Moreover, Israel and neighboring countries of Palestine are unlikely to get involved in this conflict, which makes it unlikely to develop into a full-scale Middle East war. He said that Egypt and Israel have signed a peace agreement, Syria has also held indirect negotiations with Israel and reached some consensus, while other countries such as Jordan are unlikely to get involved.

　　Wang Jinglie, director of the Middle East Research Office of the China Academy of Social Sciences, said that the Israeli attack on the Gaza can be called a "shocking" violence in the 21st century, but there is little possibility of another Middle East war in the region. He said that all the wars in the Middle East in history have involved neighboring countries, but the current conflict is only between a country and a radical organization in Israel, and it is not a big war in scale. In addition, from a deeper perspective, this war has been "planned for a long time" by Israel, and its purpose is very clear, that is, to eradicate Hamas, not the whole Palestinian territory. In addition, whether it will develop into another Middle East war depends on the attitude of neighboring countries. If neighboring countries are also involved in this conflict, it may lead to the expansion of the situation and the outbreak of the Middle East war. However, moderate countries such as Egypt, Saudi Arabia and Jordan are unlikely to be involved in the conflict, and Syria and Lebanon are unlikely to be involved. Although Iran is a variable, it is unlikely to be involved. Therefore, at present, it is unlikely that another Middle East war will break out.

　　Another international scholar also believes that the possibility of another Middle East war is very small. Strictly speaking, he said, the conflict between Israel and Hamas is not a "war" because it is not between two countries. In addition, the purpose of Israel’s attack is to "pull out" the nail of Hamas, which also limits the scale of the conflict.

　　On December 2,(601127.SH)’ s Jin Kang Sailis released a brand-new high-end brand AITO, the first medium-sized one, which is deeply empowered by Huawei.The SUV will be released on December 23rd, and it will be the first vehicle equipped with Huawei’s latest HarmonyOS OS cockpit.Xu Lin, president of Sailis (rotating), said that Sailis’s goal is to enter the first echelon within five years and become the brand of TOP3, a global new energy vehicle.

　　Affected by this news, the stock price rose sharply in the afternoon, closing at 7.023 yuan/share, up more than 4%, with a total market value of 95.508 billion yuan. It is worth mentioning that, with the blessing of Huawei concept, its share price soared from 17 yuan/share at the beginning of the year to 80 yuan/share at one time.

　　The first model will be equipped with Huawei HarmonyOS smart cockpit.

　　According to the plan, in addition to the above-mentioned medium-sized SUV, AITO has also planned three new models, namely, medium-sized pure electric SUV and medium-sized luxury SUV. It is understood that the second model, medium-sized luxury SUV, will be released next year. In addition, Cyrus plans to build more than 1,000 flagship stores and experience centers with Huawei next year.

　　It is worth mentioning that Huawei has high hopes for the first model of AITO. Yu Chengdong, CEO of Huawei’s consumer business and CEO of BU, a smart car solution, said in a video connection, "Huawei has helped AITO build a medium-sized luxury SUV with its core technologies accumulated in the fields of communication and ICT for more than 30 years." He said that HarmonyOS will get on the bus at the end of this year and early next year.

　　At the press conference, Cyrus didn’t disclose much information about the first model, but according to the information declared by the Ministry of Industry and Information Technology, the first model of AITO was named Wenjie M5, which was designed with a program hybrid, four-wheel drive and a 1.5T engine, and the maximum cruising range could reach 1,000km.

　　For AITO and Cyrus, despite Huawei’s deep empowerment, it is not easy to achieve its declared "entering the first echelon within five years and becoming the brand of the global new energy vehicle TOP3".

　　During this year’s Shanghai Auto Show, the Cyrus S jointly built by Huawei and Cyrus.Listed, the two-wheel drive version and the four-wheel drive version were launched, and the price was 216,800 yuan and 246,800 yuan respectively. The four-wheel drive version was sold in Huawei’s flagship store and was also the first car sold by Huawei. Since the sale, the official said that it has exceeded 3,000 orders in two days, and the order volume in one week has exceeded 6,000.

　　However, Seles S is not a good seller, and the market performance is not satisfactory. According to the data of the Federation, from April to October this year, the sales volume of Sailis S was 129, 204, 1,097, 507, 715, 1,117 and 1,926 respectively, totaling 5,965.

　　During the same period, the new forces of making cars includedThe delivery volume of, Ideality, Tucki and Nezha keeps rising. In the past November, the monthly delivery of, Tucki, Ideality and Nezha all exceeded 10,000, and the cumulative sales volume of second-tier new car manufacturers such as Weimar and Lingpao reached about 40,000 in the first 11 months of this year. Traditional car companies also collectively counterattacked, Volkswagen ID. Family, Guangzhou Automobile Ai ‘an and other monthly sales have been among the 10,000 clubs for several consecutive months.

　　In the face of increasingly fierce competition in the new energy market, the competitiveness of AITO as a new brand still needs time and market verification. It is worth mentioning that it was previously reported that the cooperation mode adopted by AITO was different from the previous Inside mode in which Huawei only served as a supplier. The pre-planning, product design and post-marketing of the M5 were all led by Huawei. However, this news has not been verified at present.

　　Huawei’s car adventure

　　The re-launch of high-end brands in cooperation with Cyrus once again highlights Huawei’s ambition of "building cars". Although it has declared eight times that it will not build cars, Huawei has not stopped its expansion and layout in the automotive field.

　　On November 29th, Huawei won the bid for 260,000 square meters of industrial land in Songshan Lake, Dongguan for 188 million yuan. The industrial type is smart car parts manufacturing, and the total investment of this project will not be less than 2.4 billion yuan. Earlier in October, Huawei won an industrial land in Fucheng Street, Longhua District, Shenzhen with a reserve price of 298 million yuan. The access industry categories were new generation information technology industry and new energy industry.

　　For Huawei, the original three supporting business operators BG, enterprise BG and consumer BG are mature, the growth ceiling of smart phones is within reach, and the problems of homogenization and price war are one after another. As the next most promising intelligent terminal equipment, automobiles have become an important starting point for Huawei to seek diversified development and open up new growth points. Especially after Huawei stripped off its glory and the sales of mobile phone business declined, Huawei’s determination to go deep into the hinterland of smart cars became more firm.

　　"In just two years, Huawei has encountered four sanctions from the United States, and each time it is more dangerous, it has also greatly affected Huawei’s mobile phone business." Yu Chengdong has publicly stated that the mobile phone is a high-end perceived product with high frequency, just-needed, massive and high value. However, in recent years, the sales volume of the mobile phone business has been short of supply due to US sanctions.The only thing that can make up for this lack of business is smart electric vehicles."Although the sales of cars are not as big as those of mobile phones, the value of their single products is very high."

　　Huawei’s financial report for the third quarter of 2021 shows that the company achieved sales revenue of 455.8 billion yuan in the first three quarters, a decrease of 215.5 billion yuan compared with 671.3 billion yuan in the same period last year. This is the fourth consecutive quarter that Huawei’s revenue has declined.

　　Focusing on the automobile field, Huawei Automobile Bureau has gradually deepened-from manufacturing parts of smart cars, to jointly building a new business model of HUAWEI inside with BAIC, Changan and Guangzhou Automobile, and then using its own channels to sell cars. At present, Huawei’s smart car business is mainly in two ways. In more cases, Huawei adopts the traditional Tier1 and Tier2 parts supply mode, and the other is the Huawei inside mode which is deeply tied with car companies.

　　Wang Jun said in an interview with a reporter from 21st century business herald that the essence of Huawei’s inside model is that from the time of vehicle definition, joint design and joint development, the two teams are integrated, and joint design and joint development must at least use Huawei’s full-stack autopilot solution to be called HI. "Using this model, we can give full play to the advantages of both parties. Huawei parts are all used, and the car factory has the definition, modeling and manufacturing ability of the whole car. The two sides can truly build a good car by combining with each other."

　　Although Huawei has repeatedly stated that it will never build a complete vehicle, from the perspective of business layout,In addition to vehicle design and development, Huawei is getting closer and closer to building a car.In the current and future when the competition for smart cars is becoming increasingly fierce, where Huawei’s car will end up is full of imagination.
