Recently, we obtained a real satellite photo of Xiaomi Automobile Factory from relevant channels. It is reported that the factory has 6 workshops, and it is already in the trial production stage, producing about 50 prototype cars every week, with an annual production capacity of 150,000 in the future.

Specifically, this is the first phase satellite image of Xiaomi Automobile’s factory in Yizhuang, Beijing. As can be seen from the picture, the factory has six workshops, namely, die casting workshop, stamping workshop, body workshop, painting workshop, assembly workshop and battery workshop. In addition, according to informed sources, Xiaomi Automobile is expected to get the approval from the Ministry of Industry and Information Technology during the year, and will fully accelerate the mass production of Xiaomi Automobile.

On the other hand, the construction of Xiaomi Automobile Factory will be divided into two stages. The first stage will start in April 2022 and be completed in June 2023, covering an area of 720,000 square meters and consisting of four buildings and a modern test facility.

In fact, in August, the spy photos of Xiaomi Automobile’s road test in Xinjiang were exposed, and it was said that Xiaomi Automobile will be officially listed in the first half of 2024. Looking back at the previous spy photos, we can see that the whole new car adopts a slip-back design, and is equipped with a laser radar, a five-frame wheel rim and a multi-piston brake caliper, among which the wheel rim style and caliper are different from other spy photos previously exposed. As for the side and tail, the whole spy photos have not changed much from the previous exposure. Among them, the car will use the design of frameless doors and be equipped with a semi-circular taillight group, and it is expected to be equipped with a spoiler design.

In terms of intelligent configuration, it is reported that the new car will be equipped with Qualcomm Snapdragon 8295 chip, which is ahead of the current Snapdragon 8155 chip in performance. It is expected that all new energy brands will also load the 8295 chip one after another next year. At the same time, it will also be equipped with Xiao Ai classmate (intelligent voice), car machine to get through Mijia (smart home), support mobile phone non-inductive unlocking, magnetic charging gun and so on. In addition, the car will be equipped with three laser radars, four millimeter-wave radars, and a Xiaomi Pliot driver assistance system, as well as automatic parking in the support area.

According to the previous news, the length, width and height of the new car are 4860/1980/1666 mm respectively, and the body length and width are similar to those of Tucki P7, but the height of Xiaomi car is 20 cm higher than that of Tucki P7.

In terms of power, it is reported that its battery pack has a rated voltage of 726.7V, a rated capacity of 139Ah, a battery pack capacity of 101kWh and a weight of 642kg, which means that the new car will support 800V high-voltage fast charging with great probability. In addition, it was previously reported that Xiaomi Automobile will be equipped with 90kWh and 120kWh batteries, with a battery life of 766km and 1036km respectively. Then, combined with the latest exposure of 101kWh, it is expected that its battery life will be around 900km.

To put it further, Changchun FAW Fuwei Auto Parts Co., Ltd. previously said that the company was actively communicating with Xiaomi Automobile, and many molecular companies had entered the purchasing group of Xiaomi Automobile and completed the quotation of the first model of Xiaomi. At the same time, it is reported that Xiaomi Automobile has started to screen delivery centers. Xiaomi Automobile requires that the candidate venue "can provide at least 120 parking spaces" and the construction area "cannot be less than 3,000 square meters".

The editor said:Compared with the target of mass production in the first half of 2024, it seems that Xiaomi automobile has accelerated its pace from mass production, which is worthy of recognition for Xiaomi, who is "building a car behind closed doors". Of course, its product strength is also worthy of our expectation. What kind of competitiveness can it have in the face of many rival models in the current market, and will it appear in the automobile field as a "price butcher"? As far as the current progress is concerned, what kind of performance do you think Xiaomi Automobile can achieve?

　　◎ Chen Ke Our reporter Changfeng Wu

　　With the popularity of mobile phones and electric cars, lithium batteries are playing an increasingly important role in people’s lives. However, the fire and explosion accidents of electric vehicles and energy storage power stations caused by the inherent thermal runaway of lithium batteries also make the safety of lithium batteries a problem that cannot be ignored. This is also a long-term technical challenge faced by the lithium battery industry.

　　At the Sichuan Science and Technology Awards Conference held recently, the team of Professor Xiang Yong from the University of Electronic Science and Technology of China, as the first completion unit, won the first prize of Sichuan Science and Technology Progress Award for the project "Key Technologies and Applications of Safety Control of Lithium Batteries Based on Multi-field Perception and Independent Flame Retardation". "How to improve the safety of lithium batteries and reduce the risk of overheating and explosion of batteries is a must." Xiang Yong said that in order to overcome this hurdle, he and his team have been exploring and struggling for more than ten years.

　　Overcoming three major problems of lithium battery safety

　　"Since 2012, we have gradually developed a complete electrochemical Qualcomm characterization platform and made a series of achievements in the research of lithium battery electrolytes, electrode materials and packaging materials." Xiang Yong said that he and his team began to try to apply the electrochemical Qualcomm characterization technology to the research on the dynamic change of the safety performance of lithium batteries in the whole life cycle, but during the research and development process, they found that the parameters monitored by the existing characterization methods were not enough to directly reflect the thermal runaway risk of lithium batteries.

　　In Xiang Yong’s view, the thermal runaway process of lithium batteries involves manufacturing defects, aging and deterioration, management failure, abnormal environmental conditions and other factors, as well as manufacturing, storage and transportation, service and other links, and many technical problems need to be solved urgently.

　　"There are three main problems to be overcome to solve the safety management and control of lithium batteries throughout their life cycle." Xiang Yong told Science and Technology Daily that real-time monitoring of thermal runaway of lithium battery is the first difficult problem. The difficulty lies in that conventional sensors cannot be embedded in the battery, and external signal sensing can only be relied on to infer the safety state of the battery, which will lead to inaccurate monitoring data.

　　"Early warning and protection of lithium battery thermal runaway process is the second problem." Xiang Yong said that the measures taken after the thermal runaway of lithium batteries are usually "one size fits all", that is, shutting down the whole power supply system, which can not fundamentally eliminate safety accidents and will damage the service reliability of the power supply system.

　　"The combustion blocking after the lithium battery caught fire is the third problem." Xiang Yong said that in the electrolyte of lithium battery, the organic solvent will produce flammable and explosive components when it is decomposed by heat, which will become the root cause of the fire and explosion of lithium battery after being mixed with oxygen. Therefore, once the lithium battery catches fire, it is extremely difficult to block the combustion.

　　After clarifying the R&D problems and selecting the R&D direction, Xiang Yong team, together with Sichuan Institute of Safety Science and Technology, Sichuan Institute of Product Quality Supervision, Inspection and Testing, Sichuan Branch of China Tower Co., Ltd., Southwest Petroleum University and other Industry-University-Research companies, conducted in-depth research and exploration on the monitoring and control of the safety status of lithium batteries throughout their life cycle. Under the leadership of Xiang Yong, the participating research institutes have made concerted efforts to tackle key problems, giving full play to their respective strengths in the fields of theoretical research, technology development and application promotion.

　　"We have successfully developed the in-situ preparation integration technology of multi-parameter thin film sensor and lithium battery current collector, realized the integrated integration, and solved the problem of sensor ‘ Buried, measured accurately, transmitted, with little influence ’ Key technical challenges. " Xiang Yong said that the team independently developed a special algorithm for artificial intelligence electrochemical countermeasure migration learning, and combined with the precise design model developed in the early stage, the accuracy of fault battery identification was improved to 98.6% in one fell swoop; Self-developed Qualcomm electrolyte preparation and screening technology and related devices improve the screening efficiency by 100 times, and realize the rapid optimization of the flame retardant and electrochemical properties of electrolyte.

　　On April 24th, 2022, an expert group headed by Academician Wu Feng, a famous lithium battery expert, evaluated the technical achievements of lithium battery safety series developed by Xiang Yong team. The expert group agreed: "This achievement belongs to the international frontier technology field, and its indicators, model prediction accuracy and electrolyte self-extinguishing time are at the international leading level."

　　Accumulated economic benefits exceeded 1 billion yuan.

　　Since 2019, China Tower Energy Company has applied the project results to the power supply system of China Tower communication base station, supported the real-time online monitoring of more than 500,000 lithium batteries in the standby system of Sichuan communication base station, and warned the safety risks of lithium batteries for more than 20,000 times, with a success rate of 100%. More than 13,000 failed batteries were safely returned, and fire hazards were eliminated for more than 1,500 times, which effectively ensured the safe operation of the tower communication base station without any lithium battery thermal runaway accident.

　　Shanghai Institute of Space Power Supply applied this achievement to solve the problem of sudden safety failure of lithium battery module. At present, this technology has been applied to Fengyun-4 02 satellite, new technology test satellite and other models; Sichuan Changhong Power Supply Co., Ltd. has developed a special integrated power supply with high weight ratio and high density of batteries and accessories based on the results of this project.

　　In October 2019, after introducing the technical achievements of the project, Hubei Yiwei Power Co., Ltd. further developed the online capacity prediction technology of lithium batteries, and successfully applied the new technology to the transformation of existing production lines and the construction of new production lines, effectively improving the production capacity of lithium batteries.

　　Xiang Yong told reporters that the popularization and application of the project results can help to develop high-safety and high-reliability new lithium battery products, eliminate hidden dangers of production safety risks, and also help to develop new lithium battery safety management system and improve the safety management and control level of lithium battery system. "Especially for lithium battery users, it can reduce the accident rate of lithium battery thermal runaway, reduce disaster losses and save operation and maintenance costs."

　　The data shows that since March 2019, the achievements of this project have accumulated over 1 billion yuan in economic benefits, and produced a wide range of social benefits, playing a role in serving major and key national projects.

　　Beijing, April 20 (Reporter Zhu Hongyuan) According to the economic voice "Tianxia Finance", the 17th Shanghai International Automobile Industry Exhibition in 2017 opened yesterday. As the most influential international auto show in China, more than 1,000 vehicle companies and parts companies from 18 countries and regions participated in the exhibition this year, and 1,400 vehicles were exhibited. In addition to the traditional car brands, this year’s emerging new energy car brands, and Internet car companies that have received much attention have also brought their own products.

　　The number of mass production vehicles of new energy vehicles exceeds that of traditional vehicles.

　　This year’s Shanghai Auto Show has 113 first cars in the world, while there are 159 new energy exhibition cars, including 96 domestic manufacturers. New energy, smart cars and Internet-made cars have become the general trend of the development of the automobile industry. As Yin Tongyue, Chairman of Chery Automobile Co., Ltd. said, the number of new energy production vehicles has exceeded the number of traditional vehicles.

　　Yin Tongyue: "There are about three or four new energy vehicles this year. Now new energy vehicles have exceeded the amount of traditional vehicles. New energy vehicles mainly solve pollution and national energy security problems."

　　At present, China is experiencing the largest and fastest urbanization process in the history of the world, with 20 million rural people flooding into cities every year. Although it promotes economic development and social progress, it also breeds a series of urban diseases. This has led many car companies to study the solutions of "pollution control" and "congestion control" and put forward the concept of "green transportation".　　

　　Wang Chuanfu, chairman and president of BYD, said: "As early as seven years ago, BYD launched ‘ Electrification of urban public transport ’ The solution is to give priority to the use of low-carbon and environmentally-friendly electric vehicles in the field of urban public transportation to reduce the exhaust pollution of the city. Now, this solution has risen to a national strategy. Major cities are accelerating the popularization of electric vehicles, which plays a positive role in alleviating smog. "

　　Building cars on the Internet is the future trend.

　　As far as the current development is concerned, the automobile is no longer a simple means of transportation. It will become an effective mobile means to maintain smart homes, smart grids and wireless city and build a low-carbon society. This has also prompted many internet companies to devote themselves to the automobile industry. Ge Jingdong, vice president of Sina, believes that building cars on the Internet must be the future trend.

　　Ge Jingdong: "This is the trend of cross-border integration, ‘ Internet plus & rsquo; The combination with various industries, of course, does not rule out that some enterprises in this process have not figured out what is going on, are good at telling stories well, and have not done a good job in basic work, but they will slowly go to the past and leave some truly competitive projects. "

　　It is necessary to establish a supporting system for battery treatment.

　　At present, the embryonic form of a future automobile society is taking shape, and the independent innovation and market potential of China automobile industry will leave the world with a broader imagination. In the future, new energy vehicles and smart cars will continue to emerge, but Zhao Chen, the founder of Sina Auto Car Help, also expressed his concern.

　　Zhao Chen: "But I think the biggest problem now is that we must do a good job in battery technology, and at the same time, the problems to be solved are: one is that it is difficult to charge, and the matching of residential areas and urban planning must keep pace. The second is batteries, because almost pure electric vehicles and new energy vehicles are still in a period of rapid development, but we should consider how to recycle and dispose of these batteries after these vehicles are scrapped. This is the most serious problem, and we can’t have many problems in the environment after decades of rapid development. Automobile manufacturers must play their social responsibilities, and a standard system must be established for recycling batteries and scrapping batteries. "

　　After the solar term in beginning of winter, the temperature plummeted. According to the annual clinical consultation, the risk of falls and fractures of the elderly will show an upward trend. This is related to environmental factors such as reduced activity in winter, thick clothes and slippery roads, and also related to physical factors such as aging and degeneration of various organs of the elderly. Today we will focus on the problem of osteoporosis. According to the epidemiological survey of osteoporosis in 2018, 6% of male patients with osteoporosis over 50 years old, 32.1% of female patients, and 51.6% of female patients over 65 years old in China. Our country not only has a high proportion of osteoporosis population, but also does not pay enough attention to osteoporosis. The bone mineral density of people over 50 years old is only 3.7%. In fact, both men and women have entered the early stage of bone loss since the age of 40, and we should prevent osteoporosis from this time.

　　1 minute self-examination of osteoporosis risk

　　By answering the 1-minute osteoporosis risk test of the International Osteoporosis Foundation, you can quickly know whether you have the risk of osteoporosis.

　　1. Parents have been diagnosed with osteoporosis or have been fractured after a light fall.

　　2. One of the parents has a hunchback.

　　3. The actual age is over 40 years old.

　　4. Is there a fracture due to a light fall in adulthood?

　　5. Do you often fall down (more than once last year) or worry about falling down because you are weak?

　　Has the height decreased by more than 3 cm after 6.40 years old?

　　7. Is it underweight (body mass index value is less than 19)

　　8. Have you ever taken steroid hormones such as cortisone and prednisone for more than 3 months (cortisone is often used to treat asthma, rheumatoid arthritis and some inflammatory diseases)?

　　9. Do you have rheumatoid arthritis?

　　10. Have you been diagnosed with gastrointestinal diseases or malnutrition such as hyperthyroidism or hyperparathyroidism, type 1 diabetes, Crohn’s disease or celiac disease?

　　11. Do you stop menstruating at or before the age of 45?

　　12. Have you ever stopped menstruating for more than 12 months except pregnancy, menopause or hysterectomy?

　　13. Did you have your ovaries removed before the age of 50 and didn’t take estrogen/progesterone supplements?

　　14. Do you often drink a lot (drink more than two units of ethanol every day, which is equivalent to 570ml of beer, 240ml of wine or 60ml of spirits)?

　　15. Currently used to smoking or used to smoke.

　　16. Exercise less than 30 minutes a day (including doing housework, walking and running, etc.)

　　17. Can’t you eat dairy products and don’t take calcium tablets?

　　18. Have you been engaged in outdoor activities for less than 10 minutes every day and have not taken vitamin D?

　　As long as the answer to one of the above questions is "yes", it is positive, suggesting the risk of osteoporosis, and suggesting bone mineral density testing or evaluating the risk of fracture.

　　Bone mineral density detection is suitable for the following groups

　　It is not necessary for everyone to do bone mineral density test. Compare the following self-test options to see if you need to have a bone mineral density test.

　　1. Women over 65 years old and men over 70 years old, regardless of other risk factors for osteoporosis.

　　2. Women under 65 and men under 70 have one or more risk factors for osteoporosis.

　　■ A slight collision or fall will cause a fracture.

　　■ Adults with low sex hormone levels caused by various reasons.

　　■ Those with diseases affecting bone metabolism or a history of using drugs affecting bone metabolism.

　　■ Patients receiving or planning long-term glucocorticoid treatment

　　■ Small and thin people

　　■ Long-term bedridden patients

　　■ People with chronic diarrhea

　　■ The answer to the 1-minute osteoporosis risk test is positive.

　　Normal osteoporosis

　　Remember "Five Origins and Three Stages" in Prevention and Control

　　The prevention and treatment of osteoporosis should follow five principles. First, increase bone mass and increase bone peak value; The second is to delay bone loss; Third, inhibit secondary hyperparathyroidism; The fourth is to prevent the first fracture; Fifth, reasonable dietary structure and nutritional composition ratio, quitting bad eating habits, increasing calcium intake, participating in moderate exercise and increasing sunshine.

　　Then, according to these five principles, the measures to prevent osteoporosis can be divided into three stages according to age: primary prevention, secondary prevention and tertiary prevention.

　　The primary prevention of osteoporosis is to start from childhood, to reach the highest bone mass (peak bone mass) in one’s life from childhood and adolescence to around 30-35 years old, with the goal of avoiding or alleviating the occurrence of osteoporosis as much as possible. There are mainly the following measures.

　　Reasonable dietary structure: milk is the most ideal calcium source, with 120mg of calcium per 100ml of fresh milk and a calcium absorption rate of 30%. The daily intake of calcium can be ensured by taking 500ml for adults, 750ml for children and 800ml for adolescents.

　　Choose foods with high calcium content: sesame sauce, shrimp skin, dried seaweed, kelp, milk, bean products and cheese are all foods with high calcium content.

　　Vitamin D intake: The daily intake of vitamin D is 400IU, and the vitamin D content in foods such as cod liver oil, canned sardines, egg yolk, shad and chicken liver is high. Sunlight irradiation is also one of the important ways to supplement vitamin D. Walking in soft sunshine for 40 minutes can ensure the vitamin D needed by the body. It is best to choose the irradiation time before 10 a.m. or after 3 p.m., so as to avoid too strong sunlight damaging the skin and eyesight.

　　Moderate exercise: participating in moderate exercise is helpful to increase bone mass and increase the peak bone mass.

　　Adhere to a healthy lifestyle: not addicted to alcohol and tobacco; Drink less coffee, strong tea and carbonated drinks; Less salt and less sugar.

　　When people reach middle age, they reach the secondary prevention stage of osteoporosis. The core of prevention at this stage is to delay the loss of bone mass in middle age and try to avoid the first osteoporotic fracture. Women aged 40-49 and men aged 40-64 enter the prophase of bone loss: the annual bone loss rate of women is 0.4%-0.6% and that of men is 0.3%-0.5%. Women enter the period of rapid bone loss 1-10 years after menopause, and the rate of bone loss is obviously accelerated, while men do not have the period of rapid bone loss. In addition to food supplement, physical exercise and a good lifestyle, the main preventive methods need to be supplemented with vitamin D and appropriate calcium. The recommended intake of vitamin D for adults is 400IU/d, and the maximum tolerable intake is 2000IU/d. When vitamin D is used for prevention and treatment of osteoporosis, the dosage is 800-1200IU/d..

　　The tertiary prevention of osteoporosis is the stage of mending after the sheep is dead, mainly aimed at the elderly, which is mainly reflected in inhibiting bone resorption, reducing bone turnover rate and preventing accidental injuries and fractures. Osteoporosis can be treated by supplementing calcium and vitamin D and taking anti-osteoporosis drugs under the guidance of professional doctors, so as to avoid osteoporotic fractures and re-fractures as much as possible.

　　Calcium supplementation alone cannot replace treatment.

　　The daily calcium intake standard recommended by China Nutrition Association is: 400mg； from birth to 6 months; 600mg； for 6-12 months; 800-1200mg； under 10 years old; 11-24 years old 1200-1500mg；; 1400mg； for pregnant or lactating women over 19 years old; Postmenopausal and postmenopausal women who did not take estrogen 1500mg；; Take estrogen 1000mg； for postmenopausal and postmenopausal women; Middle-aged male 1000mg；; 1000-1500mg for the elderly.

　　However, calcium supplementation alone cannot replace the treatment of osteoporosis. Osteoporosis patients can’t overcome the obstacle of calcium utilization by bones only by taking calcium orally, so they should be treated regularly under the guidance of doctors.

　　About 30% of elderly people over 60 years old and postmenopausal women have gastric acid deficiency. If they have flatulence and constipation after taking calcium carbonate, they should change to calcium citrate. The absorption of calcium citrate is independent of gastric acid and can prevent kidney calculi, which is especially suitable for those with gastric acid deficiency.

　　However, whether calcium supplementation is needed or not should be decided by consulting a specialist in a regular hospital and doing a bone mineral density examination. There is a threshold for calcium absorption. Excessive supplementation is not only a waste, but also can lead to kidney calculi’s disease, ectopic calcification and atherosclerosis. Kidney calculi, patients with advanced bone metastasis, hypercalcemia and cardiac and renal insufficiency are forbidden to supplement calcium.

BEIJING, Beijing, May 27 (Reporter Bian Liqun) "Shanghai Shenhua goalkeeper Ma Zhen committed violent acts and punched the opponent’s player in the face. He was suspended for 5 games and fined 50,000 yuan; Rodriguez, a foreign aid from Meizhou Hakka, carried out non-sports behavior and used insulting gestures to the opposing players. He was suspended for 4 games and fined RMB40,000. "

On the evening of 26th, China Football Association issued another heavy ticket. This is already the second consecutive round of the Super League, and two players have been severely punished for violence on the field.

Recently, football in China is full of anger, and in addition, the referee is insulted in the game and accused by social media. Since May, the China Football Association has issued as many as 21 tickets, most of which are concentrated in the past half month.

The fire can’t be suppressed again.

The league has returned to the home and away games, and the fans have returned to the stadium. This season, the Super League is very popular. However, recently, there has been a lot of anger.

Of course, every season, there will inevitably be angry scenes. At the beginning of last season, just after two rounds of competition, the Super League created nine red cards and five tickets.

In contrast, this season, it is an improvement to enter the third node of the league and get frequent fines.

Since the fifth round, the fire in the Super League has gradually started. Sunic, the foreign aid of Henan team, pushed down Fang Hao, a teenager from Beijing Guoan, and was suspended for five games by China Football Association, and fined 50,000 yuan.

In the same round of competition, Fan Bing, an official of Nantong Zhiyun Team, was banned from entering the competition stadium for one game and fined RMB10,000 by the Football Association for publishing the contents of questioning the referee in the WeChat circle of friends.

Coincidentally, Xie Hui, the coach of Dalian People’s Team, was also banned from entering the competition stadium for one game and fined RMB 10,000 for publishing the contents of the penalty dispute on social media.

As Nantong Zhiyun sent a long article in response to the Football Association’s fine on May 16th, the fire reached a new height.

"The facts on which the penalty decision is based are unclear and are not within the jurisdiction of the Football Association Disciplinary Committee, and the applicable rules are inappropriate; Moreover, although the punishment decision shows that there is a’ description of the parties’ by applying the template, in fact, it did not give our club or Fan Bing any opportunity to communicate, explain and defend themselves, and never held an interview meeting or hearing under the rules, lacking due process. "

"If such’ punishment decisions’ that lack legal basis and express personal opinions are allowed to flood, it will inevitably lead to illegal restrictions on the legitimate freedom of expression of football players and lead to a chilling effect."

Until now, the China Football Association has not responded to this. And a wave of unrest, a wave of rise again.

In the match between Tianjin Jinmen Tiger and Shandong Taishan Mountain on May 19th, Jia Desong, a foreign aid of Taishan Team, punched Beric, a foreign aid of Tianjin Jinmen Tiger, and the latter was injured. Jia Desong was finally banned for five games by the China Football Association and fined 50,000 yuan.

In the same round of competition between Wuhan Sanzhen and Chengdu Rongcheng, Aziz, a foreign aid from the three towns, trampled on his opponent’s leg and was banned for four games and fined 40,000 yuan.

Next, Shanghai Shenhua goalkeeper Ma Zhen and Meizhou Hakka foreign aid Rodrigo.

Why are you so angry?

Recently, the violence in China football field has been concentrated, which has to cause a question: Why are people so angry?

This season’s return to the home and away Super League, although the star flavor is insufficient after the loss of big-name stars, the game is still quite fierce.

To a certain extent, some of the anger also comes from this. Under the competition for every inch of land on the court, coupled with the blessing of the players’ own hormones in the game, irrational behavior is prone to occur.

However, combing down, the source of a lot of anger comes from some penalties.

For example, Fan Bing, an official of Nantong Zhiyun, and Xie Hui, the coach of Dalian, made speeches on social media, all of which were aimed at the referee’s penalty.

In the match between Tianjin Jinmenhu and Shandong Taishan, the players of the two teams have accumulated anger for a long time. Before Jia Desong’s boxing behavior, the fighting action has gone beyond the normal range. Unfortunately, the referee on duty failed to control the field well, which indirectly led to a large-scale conflict at the end of the game. All kinds of chaos have buried the original excitement of this goal war.

Sunic, a foreign aid from Henan province, and Aziz, a foreign aid from three towns in Wuhan, were given additional punishment for their violent behavior, but in the game, the two referees on duty only showed them yellow cards.

The Wuhan Three Towns team punished Aziz for one dollar and responded to the ticket in disguise.

Another big source of anger is the intensive schedule. Since the start of the game on April 15th, the Chinese Super League has played 9 rounds in more than one month, with each team playing once every 4 days on average.

Under the long-term consumption of double matches in a week, the players are inevitably tired of fighting, which further increases their anger.

Sparse fire can reduce fire.

Objective factors, such as the intensive schedule and the referee’s ruling level, cannot be changed in a short time. Therefore, the way of suppressing fire, which is similar to punishing improper remarks, can not reduce the fire well, but is easy to be swallowed up by fire.

Therefore, Nantong Zhiyun, Wuhan Sanzhen and other clubs responded fiercely, and the behavior of club officials abusing referees on the court and questioning referees on social media off the court became more and more concentrated.

Fans in the stands and on social media are also angry.

For the current football in China, communication needs to be strengthened, and all parties need to reduce the fire.

In fact, in the 2021 season, the Super League used the mechanism of publicly responding to controversial penalties, but it did not last long, and such responses disappeared.

In addition, some fans suggested that it is possible to reconsider choosing an international referee in some 6-point battles related to championship or relegation.

Although this move may not necessarily put an end to the phenomenon of questioning the referee and the misjudgment and omission in the court, it can still alleviate the anger caused by various trust crises.

In any case, it is really precious that the league resumes home and away games, fans return to the stadium, and some stadiums even have a hard-to-find ticket. Football practitioners in China should cherish this fire, not anger. (End)
