Huawei: The two "boundaries" are ready, and the two "boundaries" are ready to go.

With its affordable price, Zhijie S7 has pre-sold more than 20,000 vehicles so far.


On November 28th,Yu Chengdong announced the official selling price of Zhijie S7-starting from 249,800 yuan, which is nearly 10,000 yuan cheaper than the pre-sale price.

For Huawei, the significance of Smart S7 is not only that it is a "real fragrance" product that attracts a large number of consumers, but also the embodiment of Huawei’s core competitiveness and product strength, and marks that Huawei’s smart car selection business has entered a new chapter.

 

 

New energy vehicle companies with the highest sales volume must have their core competitiveness. Among them, Huawei’s smart car selection, including the core competitiveness of the intellectual and intellectual circles, is undoubtedly the high-level smart driving that Huawei empowers.

 

Some time ago, Huawei boarded the hot search because of AEB problem. Through the live test of some bloggers, we found that Huawei’s intelligent driving level is really outstanding. It was only at the full scene conference of Zhijie S7 and Huawei that Huawei showed the full strength of ADS 2.0.


In the past, we often saw drivers drive their cars slowly to the booth when attending car conferences, but the intellectual S7 was different.It can automatically drive to the booth without a driver, and face the audience at the press conference, and it can automatically drive out of the booth after the press conference.Yes, this is the strength of Huawei ADS 2.0. Users take out their mobile phones and open the App to summon cars, and the cars can automatically drive to the users.

Parking service is also a highlight of the intelligent S7 intelligent driving. Unlike automatic parking, parking service doesn’t need anyone in the car.After entering the parking lot, the owner can leave after opening the parking service, and the car will automatically find a free parking space and stop. Even if it isThe parking space is relatively narrow, and it is difficult for old drivers to park in it. There is no pressure on the intellectual S7.

 

WechatIMG588.jpg


Traditional automatic parking requires drivers to sit in the driver’s seat and concentrate on it to prevent bumping when parking. If the parking space is too narrow, the driver may need to get off and use the remote parking function.

 

Huawei is not the first enterprise to put forward the functions of Calling Auto and parking service, but it may be the first enterprise to realize and gradually popularize these two technologies.

 

In the aspect of automatic driving, which users pay attention to, ADS 2.0 also realizes more accurate and fast obstacle recognition ability through general obstacle monitoring network, RCR road topology reasoning network and other technologies. At the same time, Huawei said that by the end of 2023, NCA (Intelligent Navigation Assistance) coverage in urban areas can be achieved nationwide, and it is a map-free mode.

 

WechatIMG601.jpg


Undoubtedly, in terms of intelligent driving of core competitiveness, Huawei strives for perfection and takes the lead in achieving the goal set by its friends a few years ago. However, Huawei’s research on smart driving goes far beyond this. The core of smart driving is not only "smart driving" but also "smart travel".

 

With the blessing of AI big model and Harmony 4.0, Xiaoyi voice assistant has stronger interactive ability, can answer all kinds of questions of car owners at any time, and provide various services, such as voice-controlled booking and facial recognition payment. The whole process can be completed automatically without users’ hands-on.

 

WechatIMG597.jpg


In-car payment mode has also been proposed by car companies before, but Huawei has once again achieved it first.

 

 

The protagonist of this conference is naturally Zhijie S7, the first car of Huawei’s smart car selection business.Superb technology is only one aspect of creating explosions, and on the other hand, it has enough hard power.

 

Zero-hundred acceleration of 3.3 seconds, 0.203cD wind resistance, Turing chassis, suspension, 855 km long battery life, 800V fast charging, high-order intelligent driving, magic space, queen space, no wheat K song …

 

WechatIMG639.jpg


These functions all illustrate the Excellence of Zhijie S7, with a starting price of 249,800 yuan, and without losing the configuration and experience of Model S, 20,000 orders are only the limit of time, not the limit of Zhijie S7.

 

In fact, there is another car that announced the price at this conference, that is, the new M7 Max rear-drive intelligent driving version, with a five-seat version of 289,800 yuan and a six-seat version of 309,800 yuan, which is 20,000 yuan cheaper than the four-wheel drive version. With lower price, similar configuration and driving pleasure brought by rear drive, this car is undoubtedly very competitive.

 

WechatIMG536.jpg


Perhaps it is because Huawei and Cyrus saw the hot sale of the new M7 Max rear-drive intelligent driving version.According to Huawei’s official data, the new M7 in the world has exceeded 100,000, of which 60% is the smart driving version, and 75% of users have selected the smart driving package in the city.

 

At present, the most serious problem facing the new M7 is probably the production capacity. Huawei has stated that the expected delivery volume will reach 23,000+in December this year, and the monthly delivery capacity will be increased to 30,000+next year.

 

WechatIMG535.jpg


Another reason why Huawei is eager to increase its production capacity lies in the release of the M9—— in December, the product with the highest positioning in the car industry. The car has not been officially released, and the order volume has exceeded 33,000 units, which shows that the heat is high.

 

Ask the world to focus on SUVs, the intellectual world to focus on cars, and the route of Huawei’s smart car selection business has been determined. Relatively speaking, SUVs meet the needs of home users, while cars are more suitable for young people who pursue a sense of driving.

 

8227600 _ 20231127141045 _ 267975 _ 658279615 _ Mie7728-Edit-Edit-Edit.jpg.


The M5 Smart Driving Edition, the new M7, and the upcoming M9 have helped the car to achieve mainstream price coverage of more than 200,000 yuan. Perhaps in the future, after Huawei’s smart car selection business and the car industry realize profitability, the car industry will also launch M1 and M3 with lower positioning to achieve full coverage of major price points. At present, it is possible to make a profit if the new forces build cars and launch cars with more than 200 thousand yuan.

 

The era of the intellectual world has just arrived. An S7 is in the front line, and it is not expected to take long. S5, S9 and other models will also be released. Occupy the two mainstream models of cars and SUVs, and there are still some smaller models such as off-road vehicles and MPVs. I wonder if Huawei is willing to get involved. However, it is certain that the scale of Huawei’s smart car lineup will have a period of rapid expansion, and the brands that help Huawei achieve subsequent expansion are the remaining two "boundaries".

 

 

At the press conference, Yu Chengdong personally admitted that there are two "boundaries" coming, and the other two corresponding car companies are BAIC and JAC.

 

Long ago, Huawei HarmonyOS Zhixing registered many trademarks related to "Jiejie", such as HarmonyOS Jiejie, Yaojie, Youjie, Xuanjie and Huijie, which made preparations for other partners who might join Huawei’s smart car selection business.

 

As the most valued model of Huawei’s automobile business, under the smart car selection model, Huawei will not only provide technical support for car companies, but also use its own offline channels and the brand value and popularity accumulated by C-side operations for many years to promote them.


8227600 _ 20231127162135 _ 267975 _ 658360553 _ Mie7792-Edit. jpg

 

Today, only Changan Automobile is left in Huawei’s Hi model, but the partners of smart car selection business have developed from only Celeste to Chery, BAIC and Jianghuai.

 

In the era of new energy vehicles, the automobile industry will usher in a reshuffle. Just like the changes in the era of smart phones, it is inevitable that some old car companies will fall.


Today, with the emphasis on the Internet of Everything, full-scene intelligence is particularly important, and Huawei’s strength lies in full-scene intelligence. As early as the early days of the 5G era, Huawei launched the whole house intelligence, and now it has also included cars in the whole scene interconnection, taking the lead.

 

Up to now, there are still more than 60 self-owned brand car companies in China, and the competition among new car-making forces has reached a white-hot stage, with more and more new forces with monthly sales exceeding 10,000 yuan. On the contrary, it is a traditional car company. Except for Chang ‘an, Great Wall, Chery, Geely and BYD, the performance of other independent brands is very general.

 

It is expected that more car companies will join Huawei’s smart car selection model, use Huawei’s technical strength to help them improve their product competitiveness, and use Huawei’s brand value, popularity and offline channels to help them sell vehicles.

 

Huawei has already registered a large number of "Jie" trademarks and is waiting for them to come.

2024 Beijing Auto Show: The Great Wall will be unveiled.

Plug-in hybrid SUV BYD Tang is expected to be listed on December 20.

speed up apply the brakes oil consumption second rice rise Still very fierce to test the new BYD Tang DM 80 first. Evaluation Editor-Liang Haiwen:

For its acceleration and braking performance, in fact, this level can already be predicted before the test, and the new Tang DM 80 impressed me deeply mainly because it should be said that it has done a good job in driving quality. The quiet and comfortable feeling when driving with pure electricity will make passengers have a good riding experience, and the excellent performance of kinetic energy recovery system is also an important assistant to reduce energy consumption/fuel consumption. On the whole, if you are interested in buying a hybrid model, Tang DM is a model worthy of special consideration.

Evaluation editor-Chen Hai maid:

The hybrid system of Tang DM can be said to be relatively mature, although it has a lot of bright data, such as speeding up the results in less than five seconds. But it is a family car after all, so I am actually more concerned about its pure battery life and daily driving experience. Fortunately, I am not disappointed. More importantly, the new Tang price is quite kind. Even if you don’t want a hybrid model, then the fuel version of less than 130,000 is believed to impress many friends.

Evaluation Editor-Huang Rongjia:

It’s not news that Tang DM accelerates quickly. The old model itself is very fast, and the new generation has inherited the aura. What really surprises me is that the new generation of Tang DM is equipped with 22-inch rims and brembo six-piston brake calipers, and the vibration reduction effect is very good. If you consider that this is a medium-sized 7-seat SUV with less than 300,000, it is really exciting. For BYD, for China brand, it’s really disappointing this time, which makes people sit up and take notice.

Business War | Huawei Baidu Confronted "Urban Smart Driving"

  Last Saturday night,SubordinateThe brand launched a pure electric SUV called "New Lantu FREE". Originally, this was just an ordinary new car replacement, but when the brandAfter the car is released, 25,000 yuan can be added for optional installation.After the news of NOA intelligent driving system, it immediately triggered the industry’s response from L4 level.Attention to the competition of L2+ advanced intelligent driving.

  2023 is called "the first year of NOA smart driving in cities", and many institutions are optimistic about the outbreak and popularization of high-level smart driving in the second half of the year. For a long time in the past, only a few car companies, such as Tucki, were pushing the NOA market in the city. Nowadays, Huawei, and other powerful Internet giants have sprung up everywhere, quickly staking out the land with the attitude of "suppliers", successfully binding a number of car companies to realize the mass production of NOA, and making the market competition more and more fierce.

  Entering the "L2+" market, Baidu’s "dimensionality reduction" is against Huawei.

  The reporter noticed that the "New Lantu FREE", which was launched in mid-August, is the first new car in the mass production of NOA in Baidu City. It is officially called "Baidu Apollo Highway Driving Pro integrated product". Before this, the pace of Huawei’s intelligent driving will be faster. After the release of HUAWEI ADS 2.0 (Huawei’s advanced intelligent driving system), BAIC’s Extreme Fox Alpha S HI version, Changan’s Aouita 11 and Wenjie M5 have landed, and there will be more than ten new cars such as high-end cars cooperating with Chery in the future. According to the information released by Baidu at present, in addition to the blue map of Dongfeng, the planned Jidu car and the extreme cooperation with Geely are still on the road.

  In the field of intelligent driving with "NOA in the city" as the symbol, Baidu and Huawei finally have a battle, which has been traced before this year’s Shanghai Auto Show. On the same day of April 16th, Baidu and Huawei held their own smart car business conferences, revealing each other’s progress in NOA and other smart driving technologies. Yifu Chen, an expert on smart driving, pointed out that the smart driving car with Huawei technology is like a catfish, which has inspired the changes and progress of other smart driving systems or solution providers. At the same time, many enterprises are accelerating the shift from L4, which is difficult to make profits, to L2+, which is easier to land, and to the mass production of NOA. The reporter noticed that in the past two years, not only Baidu and Huawei, but also technology companies such as Tencent and Xiaoma Zhixing have re-recognized the future commercial profit model of intelligent driving. After Baidu’s smart car business was adjusted from L4 route to L2 this year, the new car was released in August, which means that Baidu officially opened a confrontation with Huawei at L2+ smart car track.

  The industry believes that behind Baidu’s active "dimensionality reduction" is an important decision to realize the realization of autonomous driving technology. According to CIC’s forecast, the scale of China’s autonomous driving market will increase from 2.3 billion yuan to nearly 400 billion yuan from 2019 to 2025, with a compound annual growth rate of 136%. "By 2026, the market penetration rate of L2+ advanced intelligent driving system vehicles equipped with memory parking, high-speed navigation and urban navigation will exceed 15%, and the industry will usher in an intelligent crossing period. By then, the outbreak of the high-end intelligent driving market will trigger a new round of reshuffle in the automobile industry, and the next three years will become a key window period. Whoever can take the lead in providing consumers with a safe and secure intelligent driving experience with a real sense of acquisition may gain the first opportunity in the intelligent competition in the second half. " Chu Ruisong, vice president of Baidu Group and general manager of the smart car business unit, said earlier.

  Who can grab more "smart driving" cakes?

  In terms of development mode and technical route, Baidu and Huawei have a lot in common. Who has a better chance to grab more cooperation orders? Song Yachen, a technical engineer who once participated in the research and development of autonomous driving in the new forces and now moved to a joint venture car company, said that the white-hot NOA in the city was forced by the general situation, and it was the right choice for Baidu to weaken L4 R&D and concentrate on L2+. However, he pointed out, "Huawei’s autonomous driving team is reported to have reached the scale of 3,000 to 4,000 people, and the manufacturers that cooperate with it are more obedient, which makes Huawei’s dominance high, and the progress of promoting the profitability of NOA mass production in cities will be faster. Relatively speaking, Baidu’s autonomous driving team started late in L2+, and its expansion is not as strong as Huawei’s, so personally, Baidu will not catch up with Huawei in the short term. "

  In addition, the big cake of L2+ high-level intelligent driving is welcoming many players, which makes it difficult for Baidu to snatch more car enterprise partners from Huawei. The reporter noticed that in addition to Baidu and Huawei, a number of intelligent driving suppliers have accelerated the implementation of the "parking and parking integration" scheme for NOA functions in cities. This year, Xiaoma Zhixing will mass-produce high-speed and urban parking and parking integrated assisted driving schemes; Youjia Innovation has released a high-level intelligent driving solution supporting high-speed NOA, and will realize NOA function in urban areas through OTA. In terms of mainstream manufacturers, it has also been planned to land NOA functions in related cities this year. For example, Tucki plans to open the city NGP to about 50 cities in the second half of 2023 and land in 200 cities in 2024; Huawei plans to cover the city NCA to 45 cities in the fourth quarter of 2023, ideal andAll push the city NOA internal test. In addition, Internet giants such as Tencent and Ali also have relevant technical reserves, and are involved in the research and development of car companies’ smart driving through different cooperation modes.

  Yifu Chen pointed out that in the future, whether Huawei and Baidu can compete for market share in smart driving depends on whether they can win a bigger "sinking market". According to the data of the Passenger Car Association, at present, about 100,000-200,000 vehicles account for more than 50% of the passenger car market in China, which is the car purchase price chosen by most consumers. Insiders pointed out that in order to enter the mid-range car market at this price, enterprises need to cross the three mountains of "cost", "mass production" and "full stack self-research". Judging from the current cooperation lineup, both Huawei and Baidu have chosen the "from high-end to mid-range models" style of play. First, the system will be put to the ground through cooperative car companies with large sales volume, and the recognition of consumers and the market will be sought. The next step is to enter the popularization stage of large-scale mid-range models. According to incomplete statistics, there are 26 intelligent driving suppliers in China who have launched the product scheme of "integrated parking and transportation".

  Institutional prediction: L2+ advanced intelligence drives to accelerate industrial reshuffle

  Relevant institutions continue to be optimistic about L2+ autopilot landing.issueIt is said that 2023 is the first year of urban NOA, and it is expected that the urban NOA will be released on a large scale in the second half of this year, catalyzing the smart driving market. The analysis also pointed out that the scene of L2+ high-order intelligent driving with "integrated parking and parking" is gradually switching from high speed to cities, and the autonomous driving industry will gradually transition from configuration competition to demand-led. It is reported that NOA, a city that many car companies are striving to build, is known as the last piece of the puzzle of "integrating parking and parking (integrating intelligent auxiliary systems such as memory parking, high-speed navigation and urban navigation)".

  The report also pointed out that the continuous introduction of industrial support policies and the batch landing of NOA functions in cities will enhance the available range and user experience of intelligent driving functions, promote consumers to choose advanced NOA configurations, and drive high-computing intelligent driving domain controllers supporting NOA functions in cities, andMarket space has improved. It is recommended to pay attention to the core suppliers of the smart driving industry.

  Policy support, high-level wisdom, landing

  The reporter noticed that L2+ high-level intelligent assistant system, which has more landing conditions than L4-level automatic driving, is welcoming the policy of landing. Since the beginning of the year, policies related to autonomous driving and consultation documents have been continuously released. On July 26, the countryThe Guide to the Construction of Industry Standard System (Intelligent Networked Vehicle) (2023 Edition) was officially released, which clarified that from the first stage to 2025, the system will form an intelligent networked vehicle standard system that can support the general functions of combined driving assistance and automatic driving. Previously, Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, said at the the State Council policy briefing held on June 21 that the pilot of intelligent networked car access and road traffic would be launched, and the demonstration application of "car-Lu Yun integration" at the city level would be organized to support the commercial application of conditional autopilot (L3 level) and higher-level autopilot functions.

  He also revealed that in 2022, the new car penetration rate of L2-class passenger cars with combined assisted driving function reached 34.5%.

  Zhang Kai, Chairman of Millimeter Zhixing, judged that from 2023, intelligent driving products will enter a period of rapid growth, and there will be three trends: "First, urban navigation-assisted driving products will focus on mass production and delivery in 2023. Second, the front-loading market with integrated parking and transportation ushered in the peak of mass production. Third, the commercialization of automatic distribution of terminal logistics forms a closed loop. "

Xiaomi Auto officially released: A-share hammer suppliers have exceeded 70.

On the afternoon of December 28th, Xiaomi Auto held a technical conference with the theme of "Technology Leaping, Man and Vehicle Integration". Lei Jun, founder, chairman and CEO of the group, previously said, "This time, only technology will be issued, and no products will be issued."

Since 2021, the car-making business that "gambles" on Lei Jun’s lifelong reputation is about to shine from ideal to reality after 1000 days of deep cultivation. During the car-making period, Lei Jun also compared more than 150 friendly car models. Then, what black technologies will Xiaomi car be listed soon? And which suppliers jointly support the technical base? On the basis of the press conference, Xiaomi automobile suppliers listed on A-shares may bring us some answers.

There are more than 70 A-share suppliers.

In 2023, China’s automobile industry experienced ups and downs. Under the extreme price war of new energy automobile enterprises, fuel vehicles were in a dilemma of attack and defense. Not only that, some new automobile-making forces also fell behind in the competition because they could not keep up with the market pace. The industry predicts that the competition in the automobile industry will be more intense in 2024.

In this context, the market is inevitably more worried about Xiaomi, which has been officially announced for three years and has not yet launched a production car. However, Xiaomi’s past successful experience has made the market look forward to it.

On November 15th, Xiaomi SU7 Max pure electric car and SU7 pure electric car officially landed in the 377th batch of "Announcement of Road Motor Vehicle Manufacturers and Products" issued by the Ministry of Industry and Information Technology, which means that Xiaomi Automobile is not far from listing. According to market news, Xiaomi Automobile plans to load 300 vehicles in December, and make full preparations for batch delivery next year.

However, in addition to the information disclosed by the Ministry of Industry and Information Technology, Xiaomi Automobile has not disclosed more product information at present, and the technical conference held on December 28 will undoubtedly become the closest contact between the market and Xiaomi Automobile before mass production delivery.

Lei Jun also introduced a series of leading technologies of Xiaomi SU7 at this conference. Such as ultra-high-speed motor (V8s speed reaches the highest speed of 27200rpm in the world), 871V high-voltage platform, CTB integrated battery pack (volume efficiency reaches the highest 77.8% in the world), the first battery cell inversion technology (self-built battery pack factory), high-efficiency dual-mode heat pump, three-heat source step-by-step heating technology, millet super die-casting technology (9100T: millet Titan alloy, 72-in-1 integrated die-casting floor, three-stage rear). Automatic driving (zoom BEV, super-resolution occupancy network, urban navigation NOA, valet/mechanical parking, end-to-end perception and decision-making integrated model), intelligent cockpit, platform architecture, etc.

As the saying goes, "one hero and three gangs", Xiaomi Automobile still needs the support of supply chain enterprises in the above innovative technologies. So, which suppliers have become the core base of Xiaomi Automobile’s black technology? A-share listed companies are the representatives of leading domestic enterprises. According to incomplete statistics, at present, there are more than 70 millet suppliers in A-shares. In addition to nearly 50 companies that have been disclosed before, nearly 30 concept stocks have been hammered recently.

This part of the new enterprises mainly include:, Sinomach, Hausen,Wait.

Among the new concept stocks, there are smart cockpit suppliers such as Desai Siwei, and chassis supporting enterprises such as Jinrong Tianyu. However, Lei Jun said that Xiaomi SU7 is currently in the trial production and climbing stage, and it will take several months for it to be officially listed. Affected by this, Xiaomi automobile suppliers are still in the stage of small batch supply as a whole. Jingwei Hengrun said that it is expected to achieve mass production as early as 2023.

"The whole ecology of people, cars and homes" is officially closed.

In addition to the 73 A-share listed companies and 2 Hong Kong-stock listed companies that have been hammered as above, according to incomplete statistics,、TCL、35 A-share concept stocks may have also entered the supply chain of Xiaomi Automobile, and the supply situation remains to be further disclosed by enterprises.

but, Xinsong(rights protection),Although the concept stocks that have attracted much attention have not participated in the supply of Xiaomi cars at present, there may be some variables in the future as the mass production of Xiaomi cars approaches.

In addition, Xiaomi also made a lot of investment layout before the official announcement of building a car. Among them, in the weakest automobile chip field in China, Xiaomi has participated in the creation of shares, Shanghai Xuanjie Technology, Jieping Semiconductor, Feikun Semiconductor, Shenzhen Core Energy, Microcapacity Technology, Kangzhi Integrated Circuit, Qixin Micro Semiconductor, Jingwei Qi Li, Zhanxin Electronics, Shanghai Hangxin,Intelligent, Yuntu Semiconductor, Core Bitmicro,, Mingqi Sensing, Weizhao Semiconductor, Huajing Sensing, Sirui Technology, Changjing Technology, Jingshi Intelligent,, core technology,Semi-conductive, must be easy to micro, Angruiwei, smart micro,, Nanxin Semiconductor, Huaying Microelectronics, Voda Semiconductor,A large number of enterprises, such as Zhuhai Core Test.

In the field of power battery materials, Xiaomi is also Ruilong Technology, Xinchen New Materials, Tianmu Pioneer, Sodium Energy, Farnlet, Weilan New Energy, Honeycomb Energy,, Zhongchuang Singapore Airlines,Shareholders of companies such as Weilan New Energy are expected to become new suppliers in the future with the maturity of solid-state battery technology, although the new cars to be listed soon do not use the products of investment companies.

In addition, with the gradual realization of the electric layout of the car, intelligence has been accelerated. Lei Jun said that Xiaomi Automobile will enter the first camp in 2024, and the market is also full of interest in the intelligent driving ability of Xiaomi’s new car. It is understood that the intelligent driving multi-sensor fusion scheme of Xiaomi Automobile is provided by Continental Core Intelligent Driving, a subsidiary of Continental Group, and its geometric partners are also equipped with intelligent driving schemes. In addition, Xiaomi also invested in industrial chain companies such as sagitar Juchuang, Zhuifeng Automobile, Sain Leading, Aitek, Lice Technology, Zejing Electronics, Zongmu Technology, Botai Car Network, Beixing Photon, Momenta Magic Gate Tower, and Zhixing.

In view of the demand for automotive electrification and intelligent incremental devices, Xiaomi has also invested in industrial chain enterprises such as Yingzhi Thermal Management Company, Tongyu Automobile, Jiong Yi Electronics, Kelbo, Zhilv Technology, Haizhibo Electronics, Linding Optics, Weimar Automobile, Energy Chain Group, Aoyix, Xpeng Motors, Xinan Digital, Konghui Automobile and Shendong Technology, covering thermal management, intelligent braking system, charging service and so on.

It is not difficult to see from the above introduction that the layout of Xiaomi Automobile has covered the fields of vehicle manufacturing, automobile chips, materials and autonomous driving. On December 27, Lei Jun issued a document saying that the R&D team of Xiaomi Automobile has reached more than 3,400 people. Intelligent electric vehicles are the integration of automobile industry and consumer electronics, and the technical accumulation and experience in consumer electronics also help the strength of Xiaomi Automobile. With the upcoming release of Xiaomi Automobile, Xiaomi’s "all-ecological environment of people and cars" is officially closed.

Special topic: special action against online obscenity and pornography

    On April 15th this year, our province launched a special campaign of ten departments to jointly crack down on online obscenity and pornography according to law. By May 15th, our province had closed 40 columns and websites, cracked 4 cases of online obscenity and pornography in Handan, Cangzhou and Xingtai, and arrested 7 suspects.


    On May 17th, Handan Public Security Bureau held a press conference to report the case of cracking the pornographic website "Qing Qing 99".


    1. In order to make money, four people set up pornographic websites.


    ■ 24,000 yuan for equipment


    "I just want to make money." On May 18th, at Handan Detention Center, the website of "Love 99" stood in Changjiang and said that the purpose of building the station was straightforward.


    The 34-year-old Jiang has only a primary school education, but he likes chatting on the Internet very much. In June 2006, a netizen of Jiang opened a website called "Love 99" to organize pornographic performances on the Internet. Jiang was also pulled in as an agent, and the selling card took money from it.


    It was during these days as an agent that Jiang made a small fortune, mastered the technology and operation means of making pornographic websites, and met Yang, Li, Duan and others who would cooperate with him in the future.


    Being able to chat online and make a lot of money, Jiang seems to have found the excitement.


    In August 2006, after the "Love 99" website was closed, Jiang had the idea of building his own website. After consulting with Yang, Li, Duan and others, it hit it off. Jiang invested 24,000 yuan to buy equipment, became the stationmaster and managed the website, and Yang, Duan and Li acted as agents to organize the development of members.


    ■ Charge according to the degree of nudity.


    From the video chat page of "Love 99" provided by the police, the author can see that roses, cars, villas and so on represent different points. The more gifts members give, the more explicit the actions of women who perform pornographic performances, and the performance is clearly marked on the page.


    "It is profiteering to engage in pornographic websites." Deng Xuefeng, captain of the investigation brigade of the network supervision detachment of Handan Public Security Bureau, calculated an account for the author.


    As a stationmaster, Jiang designed a virtual card by himself and sold it to the agent at the price of 100,000 "e-coins" in 35 yuan, and the agent then sold it to members at the price from 35 yuan to 60 yuan. Members can use "e-coins" on Jiang’s website to buy virtual gifts representing different points, such as roses, cars and villas.


    ■ Profit of more than 30,000 yuan in 6 months.


    The strict division of labor and pornographic performances made the popularity of this website soar quickly. Statistics from the public security organs show that only from the current accounts of an online bank in Jiang, more than 4,000 registered members are involved, and the number of online users is up to more than 200.


    Deng Xuefeng told the author that the development of this kind of chat website is like snowballing. When one person pulls another person, it will get bigger and bigger and earn more and more. The scale of Jiang’s website is not large. Although it is only less than 6 months, he still earns more than 30,000 yuan, with an average monthly income of more than 6,000 yuan.


    2, clever punches, online forensics with the help of high technology


    ■ "It is very difficult to obtain evidence in similar cases"


    On February 2, 2007, the network supervision detachment of Handan received a clue from the Ministry of Public Security and the Provincial Public Security Department that the website "Qing Qing 99" organized an online obscene performance, and its webmaster might be hiding in Handan. The network supervision detachment immediately dispatched elite soldiers to quickly set up a task force to solve the case.


    "There are many difficulties in obtaining evidence for cracking online pornography cases," Li Zengbao, captain of Handan’s network supervision detachment, told reporters.


    Jiang is well-organized, and members are introduced by acquaintances. Strangers can’t see obscene performances at all, but the information about organizing obscene performances is posted to paying members on the Internet. The time is not fixed, so it is hidden. Because obscene performances are conducted through the Internet, they disappear immediately, and they are not kept on the Internet all the time. After the pornographic performances, the contents of the performances can’t be found out from the Internet. In addition, Jiang’s accounts are traded through online banks, and Jiang and his agents are in it.


    ■ Network police "disguised" to become a VIP


    Apart from the clue that Jiang was hiding in Handan, the task force didn’t know much about the "Love 99" website. In order to investigate and collect evidence, the police sent personnel to log on to Jiang’s website disguised as ordinary netizens.


    From the homepage of "Qing Qing 99" website intercepted by the network police, this is an ordinary chat website. The words "No dissemination of obscene and pornographic information" are clearly marked on the top right of the homepage. The whole page is neat and clean, and there are no words related to obscenity and pornography.


    "The tricky part lies in the ordinary member area and VIP member area." Deng Xuefeng explained that there is no pornographic performance in the ordinary member area, so you can enjoy special "treatment" by paying to register as a VIP member and entering the room with obscene pornographic performances.


    Deng Xuefeng was rejected when he first applied to Jiang for VIP membership. Jiang was always wary of netizens who were not introduced. After three days of continuous inspection of Deng Xuefeng, Jiang agreed to his application to become a VIP member.


    ■ Network police use the Internet to collect evidence


    After becoming a VIP member, the police found that most of the members here were obscene and pornographic when chatting with each other. Before each pornographic performance, the webmaster or agent will release information from time to time to inform VIP members when and which "room" will have a performance.


    Because the performance time is not fixed, the network police are divided into two classes, insist on being online 24 hours a day, monitor the website and collect a lot of evidence.


    On February 15, when the police conducted undercover investigation on the website, they found a VIP "room" clearly marked that others should not enter.


    "There must be something in it." Deng Xuefeng prepared screenshots and download tools and suddenly broke in. It turned out that Jiang and Yang, Li and Duan were in a meeting to discuss the development of the website and the distribution of benefits.


    The police quickly took screenshots and immediately started downloading videos. Although Jiang was soon aware that a stranger had entered and cleared Deng Xuefeng out of the chat room, the police still obtained valuable information. The realistic appearance of Jiang and others was presented to the police for the first time, which created conditions for the case to be closed and the results to be expanded.


    3. After searching hard, the police decisively attacked the principal offender.


    ■ "What is more difficult than obtaining evidence is to find the hiding address."


    "It is more difficult than obtaining evidence online to find out the hiding address of criminal suspects," Deng Xuefeng told reporters.


    Several agents are scattered in different cities across the country-Duan is in Taiyuan, Li and Yang are in Chongqing. Although he was in Handan, he didn’t just manage the website at home, but frequently changed Internet cafes, shot a gun and changed places, and played guerrilla warfare with the network police. After repeated detection by technical means, the network police determined that Jiang should be hiding in Anzhuang Village, Sijiqing Township, congtai district City, Handan City.


    "It’s a headache to mention Anzhuang Village," said Cui Zhenhong, a policeman. Anzhuang Village is a big village, with nearly 1,000 households. More than 60% of the villages are rented houses. There are many migrants and hutongs, and the terrain is complex, so it is very difficult to find rows.


    Since there is only one blurred photo of Jiang intercepted on the Internet, six police officers handling the case have been groping in Anzhuang Village for half a month without any progress.


    Just when he was at a loss, Cui Zhenhong overheard a villager say that a website maker near his home had made a lot of money while chatting with the villagers. "I almost jumped up at that time." Cui Zhenhong was still a little excited when he recalled the clue.


    After confirmation, it is Jiang, who is hard to find in the mouth of the villagers, who rents in the courtyard at the corner of an alley. There are still six families renting the same yard with Jiang. The police did not dare to rush in to investigate, so as not to startle the snake. They just laid eyeliner and stared at Jiang.


    ■ Jiang fled Tianjin two hours later.


    On March 8, when the police logged on to "Love 99", they found that the website was closed. Did Jiang hear the wind and prepare to escape?


    If the personnel are hidden after the website is closed, it will be particularly difficult for the police to find the suspect, and the investigation of the case will also be passive. So Handan City Public Security Bureau immediately formulated the arrest plan and decided to carry out the arrest.


    The police who rushed into the rental house were shocked. Jiang had gone to the building and the computer for committing the crime was removed.


    The police learned from the landlord that Jiang had just moved away, and things were temporarily placed in a villager’s home and could come back at any time. "Old Cui stayed in front of Ziqisheng wholesale and retail store on the left side of Hutong, and went to Liuji Beef Ramen Restaurant on the right side of Hutong, and Xiao Deng went across the road." Li Zengbao quickly arranged for the police to carry out network control on several key parts.


    Two hours later, Jiang finally appeared, two policemen followed behind him, and Deng Xuefeng went around to Jiang from across the road. After the three people made a hint of arrest, they swarmed and grabbed Jiang.


    According to Jiang, as the wind of the police cracking down on online pornography is getting tighter and tighter, he has already recovered the cost and earned money. He wants to escape to Tianjin to avoid the limelight. "It’s only two hours." Jiang seems a little annoyed.


    Subsequently, the police arrested the rest of the main suspects, traveled tens of thousands of kilometers to Shanxi and Chongqing, and solved the case of obscene pornographic performances organized by the network in one fell swoop.


    The police arrested four suspects involved in the case, seized six computers involved, and confiscated illegal income of more than 50,000 yuan.

People’s body talk: the charm of football and grassroots feelings

Source: People’s Daily Online-Viewpoint Channel Original Draft

On November 17th, in the second round of the 2022 Chinese Football Association Cup, the Chinese champion team Jingchuan Wenhui eliminated the Chinese Super League team Beijing Guoan 7:5 in a penalty shootout and advanced to the top 16. This game surprised many people. Losing to a semi-professional team as a traditional strong team in the Super League may be caused by various reasons, but it also made many people know more about the current situation of football in China and look forward to the development of grass-roots football.

The FA Cup is an independent knockout cup outside the football league in China, and it is also the only opportunity for low-level teams and high-level teams to compete together. Jingchuan Wenhui eliminated Beijing Guoan from penalty. Although there were accidental factors, from the process of 2:2 draw in regular time, the strength of the two teams was close, and Jingchuan Wenhui team even got the upper hand slightly. Two goals were remarkable. The players on the field were thunderous, calm and confident, and had a degree of attack and defense. In a game in which the strength is very different and there is no suspense, the audience felt the long-lost charm of competitive football.

Aside from the mobilization, cohesion and team fighting capacity before the game, we can find details that are easily covered up by victory from the voice of the head of Jingchuan Wenhui after the game. Jingchuan Wenhui said that the main reason for winning the game was that the opponent was negligent and could not use foreign aid. He attributed the opponent’s defeat to accidental factors and external uncontrollable rules. Compared with the simple ceremony of "accepting and accepting", he was polite, modest and humble, which was quite the bearing and pattern of Chinese traditional culture. Brutalizing its physique, civilizing its spirit, an unexpected game, let us see the momentum and indomitable feelings of grassroots football.

Football is round. The competitive characteristics and rules of the game make football not only have the integrity, antagonism and appreciation shared by collective ball games, but also have the variability of technical and tactical coordination and the contingency of game results.

"The prime minister must start from the state department, and the fierce generals must be sent to the pawn." According to the results of post-match interviews and data disclosure, there are 152 players in Jingchuan Wenhui Football Club, more than 70 of whom are local doctors, policemen, teachers and other amateurs from all walks of life, and 40% of the players participating in the FA Cup are semi-professional players. Jingchuan Wenhui Club is integrated with Beihai Jichi Club, co-built and shared with Jingchuan County key amateur sports schools, and has a champion team, an U19 echelon, an U17 echelon and an amateur team, which reflects the effectiveness of Jingchuan County Football Association reform. The development of grass-roots football in Jingchuan presents a good trend, which is not only the component of football professionalization reform, but also supported by the three-level training network of competitive sports national system, and the association, sports school and club cooperate and form a joint force. The deepening reform and practice of county-level individual associations, the development of county-level football clubs and the modernization process of amateur sports schools are all key and difficult points in the construction of a strong sports country and the development of grass-roots sports organizations. For the government and an effective market, it may be the internal logic of the wonderful performance of this grassroots counterattack.

If the road is long, the line will come, but it is difficult and more brave. We expect the society to pay more attention and support to grass-roots football, and we expect that the sports lifestyle with football as the carrier can meet the needs of more people for a better life!

A little more news "
How to distinguish mycoplasma pneumoniae, influenza virus and Covid-19?
The symptoms caused by mycoplasma pneumoniae, influenza virus and Covid-19 are similar. How to judge that the etiological diagnosis can be confirmed by antigen and nucleic acid detection?
Chen Meifang, deputy chief physician of the Department of Infectious Diseases, Peking University People’s Hospital, said that it is difficult to judge whether it is influenza, Covid-19 infection or superimposed infection. The clinical symptoms of influenza mainly include chills, high fever, fatigue, muscle aches, headache and other systemic toxic blood symptoms, and may be accompanied by respiratory symptoms such as cough, sore throat and runny nose. Generally speaking, the symptoms of toxic blood are severe and the respiratory symptoms are relatively mild. Abnormal sense of smell and taste are the unique accompanying symptoms of Covid-19 infection.
Chen Meifang said that early identification and definite diagnosis require simultaneous detection of antigens and nucleic acids of novel coronavirus and influenza viruses. Antigen testing can be done at home by yourself, but pay attention to sampling in strict accordance with the instructions to avoid false negatives. Because the early positive rate is low, some of them need to be tested several times in a row. If infection cannot be ruled out, nucleic acid detection is needed, because nucleic acid detection is more sensitive than antigen. In the later stage, antibody detection can help to make a definite diagnosis.
Some respiratory disease experts analyzed: "Under normal circumstances, if the rapid antibody detection method is used, there will be problems that cannot be detected. This is because the antibody of Mycoplasma pneumoniae appears late, which may not appear until about a week after infection. If PCR nucleic acid detection is used, it will be more accurate, but it will take longer and cost more."
The long incubation period is a remarkable feature of mycoplasma pneumoniae infection, and the average incubation period of pathogens after exposure is 2 ~ 3 weeks.
Wang Xinyu, deputy director of the Infectious Diseases Department of Huashan Hospital affiliated to Fudan University, said that there is no clinical or imaging feature that can clearly distinguish mycoplasma pneumoniae pneumonia from pneumonia caused by other pathogens. It is not necessary for ordinary mild patients to go to the hospital for PCR detection at the beginning; If the patient’s symptoms are serious, it needs microbiological diagnosis, such as PCR nucleic acid amplification test to help the diagnosis.
In addition, due to the self-limitation of respiratory virus infection, not all of them need antiviral treatment, and some can relieve symptoms. However, for the elderly, children under 5 years old and special people with low immunity, they should seek medical treatment in time. For example, when a child has superhigh fever or persistent fever for more than three days, frequent coughing affects his normal life, his mental state is not good, and even he has drowsiness, increased breathing frequency or difficulty breathing, frequent vomiting, rash, headache or convulsions, etc., he should take the child to see a doctor in time.
Several misunderstandings about respiratory diseases
Mycoplasma pneumonia is a variation of COVID-19?Tong Zhaohui, director of the Beijing Institute of Respiratory Diseases, said that mycoplasma was discovered in the early 20th century, and it was not confirmed that it was a pathogen until the end of the 20th century, while Covid-19 was not known until the end of 2019. There is no relationship between them. Why are children particularly susceptible to mycoplasma infection? Tong Zhaohui said that children’s immune system is underdeveloped and their resistance is not as good as that of adults, so they are more susceptible to infection.
Once you have a cold and a fever, you have to get an infusion quickly?Tong Zhaohui said that "the infusion of cold and fever is faster", which is actually a misunderstanding. Compared with the flu, the temperature of cold and fever is lower, and the symptoms are lighter, often the symptoms of the upper respiratory tract. If you have a fever or cough after a cold, you can take antipyretic or cough-relieving drugs at home. Pay attention to rest, drink plenty of water and supplement nutrition. For the flu, some flu may cause pneumonia or even severe pneumonia. At this time, you may have to be hospitalized, and the resident doctor will judge whether you need infusion. Zhang Wenhong also said that general infusion is limited to hospitalized critically ill patients, or some drugs cannot be taken orally and can only be infused. For the common cold, oral medicine is more effective.
Mycoplasma pneumonia can completely heal itself at home?Tong Zhaohui said that in most cases, whether it is a virus or mycoplasma, if it is confined to the upper respiratory tract, most of it can heal itself, and a small part may develop into pneumonia. Zhang Wenhong said that in general, mycoplasma pneumonia can be improved by some symptomatic drugs at home, but it is necessary to pay attention to whether it develops in the direction of severe illness. For example, if the child’s situation improves after taking the medicine, he can observe it at home; If you still have a high fever after taking antipyretics, you should seek medical advice as soon as possible.
