Recently, a game called "cigarette card" has become popular, and this toy made of cigarette box cover has almost become the hot flow of some short video platforms. So how did "cigarette cards" become toys? Can "cigarette cards" be sold? Will it have a bad influence on children? With these questions, the reporter conducted an investigation.

　　"cigarette card" spreads and sells the hardest hit areas.

　　Mostly short video platforms.

　　First of all, the reporter’s understanding of the "cigarette card" is in a short video in Tik Tok. A child rummages around the ground with a plastic bag, and the dialogue expresses that he is looking for a cigarette case on the ground. Then the boy skillfully tears open the cigarette case and folds the lid to make a "cigarette card". For how to use this game prop made of cigarette cases, a large number of video covers featuring children will appear immediately after entering "cigarette card" on the vibrato platform. The introduction of "smoke card" in different videos is also varied. The most conventional way of playing is to put the cigarette card on the ground and take turns to shoot it. Whoever can flip the other person’s cigarette card will win the other person’s cigarette card, and the more expensive the cigarette, the more advanced the cigarette card.

　　The reporter found that in some short video platforms, there are also many self-media bloggers who shoot "smoke cards" to make videos, with thousands of praises. After searching for "cigarette cards" on Tik Tok, a large number of videos involving "cigarette cards" will appear, and most of the protagonists on the front pages of these videos are children. The number of likes of these "Smoke Card" videos featuring children even reached more than 100,000, among which a Tik Tok author with more than 1.5 million fans liked a video of "Smoke Card" up to 130,000. Another Tik Tok author’s video content is to encourage children to play with "cigarette cards", and specially bought cigarettes to make "cigarette cards" for children, with the caption "I feel very proud to collect so many cigarette cards in front of children at once".

　　The reporter found that some publishers of these videos about "cigarette cards" hung up a link to sell "cigarette cards" in the lower right corner of the video. When you click in, you will find that it is actually a shop selling "cigarette cards", and the price ranges from 3 yuan to tens of yuan. Some merchants have marked slogans such as "First-hand goods, see who has more than me" and "There is a high probability of exploding rare cards, and my mother no longer has to worry about me going out to pick up cigarette cases".

　　The reporter also noticed that the "cigarette card" was not only on the short video platform, but also on the e-commerce platform. After searching for "cigarette cards" on a shopping platform, it is found that there are many buyers of some goods called "out of print", "rare" and "cigarette cards", and the store with the highest sales volume on the homepage shows that "20,000+"has been sold. Searching for the same keyword on another shopping platform will show the goods that have been "spelled 1 million+pieces". On the Internet, the price of a "cigarette card" generally ranges from 10 cents to 50 cents, and some "rare models" are more expensive. Among them, the price of a card book containing 200 rare and non-repetitive cards is as high as 399 yuan. Most brands emphasize that they are "real cigarette cases, no printing" in a conspicuous position on the page, and most buyers’ comments are "children like them very much". However, the reporter also noticed that some buyers mentioned some problems in their comments, such as "cigarette cards", "some dirty, garbage recycling at first glance" and "obvious smoke smell".

　　Wholesalers push hard.

　　Stationery shopkeepers resolutely resist.

　　In addition to these "cigarette cards" sold online, are there any "cigarette cards" sold in places where children can buy them in life? The reporter visited stationery stores near different primary schools such as Heping District, Nankai District and Hexi District, and found no cigarette cards for sale. During the interview, the female shopkeeper of the stationery store next to Pingshan Road Primary School in Hexi District told the reporter, "There are’ cigarette cards’ in the wholesalers, and they also told us that’ cigarette cards’ are particularly popular now, and they will definitely sell well. However, considering that everything related to cigarettes is not good, there are many children who come to buy things here, and we have to check for our parents and not sell everything. We think that thing is unsanitary, and the cigarette case is used to hold cigarettes, and it is all used up by others. How dirty it is. "

　　Regarding the possible harm caused by the "cigarette card", will the "cigarette card" make children bury the possibility of smoking? A male shopkeeper who runs a stationery store near the Water Park Primary School in Nankai District said, "I will never sell that thing in my shop." He said that he smokes, and he has given up smoking many times without success. He absolutely does not allow his children to smoke. In his view, "cigarette cards" are being sold all over the internet, which means that some people are cultivating potential consumers, all know that smoking is harmful to health, and it is "too hateful" to seduce children to play with "cigarette cards".

　　Bad Push of Short Video

　　Parents feel that the hidden danger is huge.

　　What is the impression of "cigarette card" among parents and children? The reporter interviewed the parents of Xikang Road Primary School in Heping District after school hours and talked about the "cigarette card". A parent who was picking up the child told the reporter that he knew that there was such a toy as "cigarette card" from his son, and his son also asked his father for a cigarette case to do it himself. He said, "When my son was in the fourth grade, I suddenly felt something was wrong when he asked for a cigarette case that day, so I asked him carefully. My son showed me a short video on his mobile phone showing you how to fold a cigarette case, so I didn’t let him see it at that time, telling him that cigarettes contain nicotine, which will make people sick." The parent said frankly, "Many popular games are now played in Tik Tok, and some should not be played for children at all. I now forbid our children to watch Tik Tok."

　　This parent’s statement resonated with many parents. A parent with a girl at home showed reporters the short video records that his children had browsed on his mobile phone, including the push of "cigarette cards". This parent feels that some short video platforms now start to push regardless of good or evil after collecting personal big data, and the "smoke card" is also on fire. He said: "Because the children in primary school are still young, the possible negative effects on cigarette cards while playing games cannot be distinguished and resisted, so schools and parents should intervene in time once they find out."

　　The sale of "cigarette cards" is suspected of being illegal.

　　There is a ban on the education department.

　　The reporter learned by inquiring about the relevant legal provisions that according to the relevant provisions of the Regulations on the Implementation of the Tobacco Monopoly Law of People’s Republic of China (PRC), the trademarks cut off from discarded cigarette cases, that is, the items called "cigarette cards" by children, are not allowed to be sold by merchants in any way. At the same time, the tobacco monopoly law clearly stipulates that the trademark logo of tobacco products must be printed by enterprises designated by the provincial administrative department for industry and commerce, and non-designated enterprises may not print the trademark logo of tobacco products. The Law on the Protection of Minors also stipulates that there should be no sales outlets for cigarettes, alcohol and lottery tickets around schools and kindergartens, and it is forbidden to sell cigarettes, alcohol and lottery tickets to minors or pay lottery prizes.

　　According to media reports, at the end of March this year, law enforcement officers of Haikou City Supervision Bureau of Hainan Province conducted special inspections on the sales of "cigarette cards" in stationery stores and toy stores around schools in their jurisdiction. On April 7th, the Education Bureau of Sanya City, Hainan Province issued "Important Tips for Preventing Students from Addicting to" Cigarette Card "Games", which made it clear that "Cigarette Card" comes from discarded cigarette cases, and collecting it around and carrying it with you may endanger students’ physical and mental health; In addition, students may enlighten their gambling consciousness in the game and have interest and curiosity about smoking. Parents are requested to cooperate with the school to prohibit "cigarette cards" from entering the campus. Once the school finds that students bring "cigarette cards" into the school or find that students are playing "cigarette cards" on campus, it can immediately stop and confiscate the "cigarette cards" on the spot, and at the same time conduct oral education and give feedback to parents.

With the approaching of Chengdu Auto Show in 2024, major car companies are ready to go. After all, Chengdu Auto Show, as a key exhibition connecting the traditional sales season "Golden September and Silver 10", has naturally become an ideal springboard for many car companies to sprint at the end of the year. According to the current known news, there are quite a few heavy new cars that will be unveiled during the auto show. Among them, the following four new energy vehicles have their own lucky number "7". Next, let’s take a look.

As the latest medium-sized SUV of Aouita brand, Aouita 07 is expected to be launched at Chengdu Auto Show and open for pre-sale. As for the price, the wheelbase and size of Aouita 07 are smaller than that of Aouita 11, and the starting price may be around 250,000 yuan. If it is this price, it is expected to bear the heavy responsibility of brand volume.

The new car adopts AVATR 2.0 design concept, and the appearance lines are smooth. The car is equipped with a 15.6-inch central control screen and a 35.4-inch 4K integrated remote screen. It is equipped with Huawei’s intelligent driving system and provides two power options: extended range version and pure electric version. The extended range version is equipped with a 1.5T range extender and a motor, and the cruising range of the pure electric version can reach up to 650km. As the first Aouita 07 in the family to adopt the extended-range hybrid system, it may attract users with endurance anxiety, thus increasing brand sales.

As the second production car of the brand, Extreme Yue 07 is positioned as an "automobile robot" and will be pre-sold at Chengdu Auto Show. In terms of appearance, the Extreme Yue 07 is equipped with intelligent interactive headlights, the tail is equipped with automatic lifting tail, and it is equipped with intelligent ISD interactive piano key taillights. The side of the car body is designed without a door handle and equipped with an electric induction door. It is worth mentioning that the whole vehicle achieves Cd 0.198 ultra-low wind resistance.

In terms of cockpit, the car provides a half-width steering wheel and an integrated large screen with 35.6-inch 6K resolution. In addition, the car is also equipped with ROBO SOUND lifting multi-star stage speakers, seat breathing gooseneck lights, 7-inch rear display screen, starship surrounded by flowing water atmosphere lights, wireless charging and other luxury and comfort. In terms of power, Extreme Yue 07 will launch three power models, including a single motor with 400V architecture and a double motor with 800V architecture, with a maximum power of 400 kW, showing strong performance strength.

As the first medium-sized SUV of Krypton brand, this new car is launched to help Krypton seize more market share of pure electric SUV. In terms of appearance, the new car adopts Hidden Energy design language, and is equipped with through-blackened combination headlights and a real-time light curtain of "magic painting cloth", showing the avant-garde visual effect.

In terms of power, the new car is built on the vast architecture of SEA. The whole system comes standard with 800V high-voltage platform, providing 310 kW single motor and 165/310 kW dual motor options. In terms of battery life, CLTC battery life covers 605, 600, 705, 770 and 780km, meeting consumers’ demand for long battery life.

In fact, as early as before, Yu Chengdong revealed the pre-sale price of the new M7 Pro at the press conference of Enjoy World S9 — — Starting from 249,800 yuan, this price can be said to be the lowest among the new M7 cars in the world, and it is confirmed to meet you at Chengdu Auto Show. I believe everyone is most concerned about why the price of the new M7 Pro is so low.

Mainly because it uses the basic version of HUAWEI ADS. This intelligent driving system can only realize the intelligent driving navigation of national highways and urban expressways without relying on high-precision maps, and there is no laser radar, so the cost of software and hardware is lower than that of the new M7 Ultra. In fact, for most consumers, this intelligent driving system is enough, and the brand-new model is likely to become the best-selling version in the whole car system.

The above four models that will be unveiled at Chengdu Auto Show are also considered as new energy vehicles with high attention on the market. So which one do you think is more important? Which car do you prefer? Welcome to leave a message in the comment area.

Original Zhao long’s bottom line thinking

Text/Observer Network columnist Zhao Long

Deputy Director and Researcher, Institute of Global Governance, Shanghai Institute of International Studies

Since the beginning of the year, the mentality changes of the United States, Europe, Russia, Ukraine and other parties about the Ukrainian crisis have gone through several obvious stages. On the one hand, "Ukraine can’t lose" is still the clearest target bottom line for the United States, Europe and Ukraine; On the other hand, strategic anxiety and war fatigue are constantly affecting social and political consensus, especially reflected in the domestic political agenda of some countries.

In this context, is a "long ceasefire" equal to a "long peace"? How to define the standard of victory and failure? How to evaluate the future applicability of "East-West Germany" and "Peninsula Model" in Ukraine is no longer a taboo topic discussed by all parties.

After Trump won the election, his campaign slogan of "ending the Ukrainian crisis within 24 hours" ignited the expectations of all parties for a ceasefire.

On November 16th, local time, Ukrainian President Zelensky said in an interview with the media that he was convinced that the war would end "faster than before" after Trump took office, and Ukraine would "make every effort to ensure that the war would end next year".

It is undeniable that in the Trump 2.0 period, Russia and Ukraine resumed some form of contact and even started ceasefire negotiations, which is worth looking forward to. To put it simply, Trump’s position on the Ukrainian crisis may include three aspects:

First, by threatening to interrupt aid, Ukraine was forced to return to the negotiating table and asked to make non-sovereign compromises on territorial issues;

Second, let Europe bear more economic costs, including expanding the procurement of American weapons to aid Ukraine and the main part of the funds needed for post-war reconstruction in Ukraine;

The third is to "freeze conflicts" based on Russia’s actual control line and persuade Russia to complete the transaction.

However, there seems to be some illusion that Trump can quickly end the war. In fact, Trump’s return is a necessary condition for Ukraine to achieve peace, but it is not a sufficient condition. Because although all parties support the resumption of negotiations between Russia and Ukraine, there are many differences on what to talk about and how to talk about it.

For example, Europe insists that negotiations must be "beneficial to Ukraine", while Russia emphasizes "based on territorial reality" and the Istanbul Consensus in April 2022. Countries in the south of the world emphasize a ceasefire as soon as possible from the perspective of reducing casualties. According to the experience of various regional conflicts and local wars in the past, after the parties resume contact, they still need to complete a temporary ceasefire, start negotiations, establish a demilitarized zone, sign a ceasefire agreement, and establish an international supervision mechanism, so as to achieve lasting peace.

At the same time, the huge casualties suffered by Russia and Ukraine on the battlefield in the past three years and the contradiction of sovereignty over 18% of Ukraine’s total territory have determined that it is difficult for a single country or individual to achieve a ceasefire and stop the war on its own.

For Trump and his "MAGA" (Make America Great Again) line, reducing the economic cost paid by the American people for the Ukrainian crisis is the core concern. If Europe is willing to bear more economic costs and increase the purchase of American weapons to aid Ukraine, Trump may not exclude the Ukrainian crisis from continuing in a low-intensity way for the sake of maximizing his own interests. Even if the United States completely stops aid, Europe’s commitment and determination to support Ukraine cannot be underestimated, including continuing to break through legal disputes and using frozen Russian assets to aid Ukraine.

What’s more, the "peace plan" proposed by Trump and his team involves "establishing a demilitarized zone according to the existing contact line, Ukraine’s commitment not to join NATO within 20 years, and establishing a ceasefire monitoring mechanism with the participation of a third party". These potential plans have been discussed many times in various second-track dialogues, and they are not very creative new ideas. Among them, European countries, not the United States, are responsible for supervising the implementation of the ceasefire between Russia and Ukraine, and the vague statements on sensitive issues such as territorial control and ownership have led all parties to question the enforceability of the "peace plan."

For Russia, compared with the political and economic costs caused by the delay of the war, a simple "freezing conflict" may not be the best option. Before Trump takes office, Russia may launch a new wave of offensive against Ukraine, and set the main goal as to recover the "lost land" in Kursk region, and strive to limit the focus of future negotiations to the areas that Russia has not controlled in the four eastern Ukrainian States, instead of simply ceasing fire according to the actual contact line.

The most important thing is that Putin and the establishment forces in Russia have absolute distrust of the United States and Europe and will not be easily satisfied with signing the 3.0 version of the Minsk Agreement under the political commitment of the United States and Europe. This is why the future peace plan cannot be limited to the coordination between Russia, Ukraine, the United States and Europe, and other countries need to participate.

On November 19, local time, some pictures of the explosion of GRAU armory appeared on overseas social platforms.

It is worth noting that out of concern that Trump may force Ukraine to compromise with Russia after taking office, Biden will not only consider how to characterize the Ukrainian crisis as a "legacy" in the last two months of his administration, especially how to unite allies to contain Russia’s achievements, but also pay attention to how to create a "trap", vigorously promote NATO to fulfill its existing military aid commitments, and strengthen Ukraine’s offensive and defensive capabilities on the battlefield and its negotiating position outside the battlefield.

At the same time, Biden may tolerate or even let the limited controllable escalation of the battlefield, preventing Trump from making a deal with Russia as a "abandoned child". Recently, Biden’s lifting of Ukraine’s restrictions on using long-range weapons aided by the United States to attack targets in Russia is an example of this change in position. On November 19th, the "RBC- Ukraine" news agency quoted an insider of the Ukrainian army as saying that the Ukrainian army had used ATACMS to attack a military facility near Karachev, Bryansk, Russia.

At the same time, the military cooperation between Russia and North Korea has aroused great concern from all sides at a critical period when the Ukrainian crisis may enter "talking while fighting".

Theoretically, the military cooperation between Russia and the DPRK under the framework of the Comprehensive Strategic Partnership Treaty belongs to the category of bilateral relations in nature, and the article 4 of the Treaty concerning "military mutual assistance" cannot be simply equated with the NATO standard "military alliance". According to the Treaty, when Russia and the DPRK provide military assistance to each other in the face of aggression or in a state of war, it is necessary to comply with Article 51 of the Charter of the United Nations and relevant domestic laws.

Judging from the background and content of the signing of the Treaty, it remains to be seen whether military cooperation based on similar environmental perception, interest perception and strategic needs can solve the shortcomings of the fragility and singleness of mutually beneficial relations.

On November 16th, the Financial Times quoted the Ukrainian intelligence assessment report as saying that North Korea had provided Russia with 50 170mm M1989 self-propelled howitzers and 20 upgraded 240mm multi-barrel rocket launching systems. The picture shows the "main gun" shot in Russia.

For China, such cooperation may strengthen the linkage between "European security" and "Asian security", and provide more "reasons" for NATO members in Europe to strengthen their substantive presence in the Asia-Pacific region. If the military cooperation between Russia and the DPRK goes beyond the geographical restrictions, it may break the consensus that a third country does not directly intervene in the Ukrainian crisis, causing concern about the spillover of the battlefield and the escalation of war.

Considering the high political sensitivity of this issue, it is believed that Russia will give priority to its own territory in positioning military cooperation, and may refer to the mode of NATO’s military advisers, technicians and various mercenaries and volunteers stationed in Ukraine to create a "gray zone" for military mutual assistance, so as to avoid sending North Korean soldiers to eastern Ukraine to directly participate in combat, thus triggering a qualitative change in the Ukrainian crisis.

What needs to be made clear is that China’s main concern is to ensure that there will be no war and chaos on the peninsula and that the "battlefield will not spill over, the war will not escalate, and all parties will not fire" in the Ukrainian crisis.

Since creating the image of "President of Peace" may become one of the main contents of Trump’s political legacy, he may seek positive interaction with China in order to promote the Ukrainian crisis, the Palestinian-Israeli conflict and the relaxation and stability of the situation on the peninsula after taking office. The dialogue between China and the United States on these international and regional hot issues is also expected to become a lubricant for the fierce struggle between the two countries on issues such as economy, trade, science and technology.

But frankly speaking, Trump’s interest in bringing China into the Ukrainian peace process may be limited until his unilateral "persuasion and promotion of talks" encounters resistance or even fails.

　　[New car listed in car home] On January 25th, (|) was officially listed.A total of five models were launched.The price range is 439.9-639.9 million yuan.As the mainstay of BMW brand, the 5 Series family has been the eighth generation brand-new model since it was born in 1972, and it has brought pure electric BMW i5 for the first time, which indicates that the best-selling BMW has entered the era of intelligent electric. In terms of car purchase benefits, BMW /MINI owners who purchase BMW i5 models can choose up to 18,000 yuan for purchase tax and insurance support.

● New car features

　　In terms of appearance, the i5 and 5 Series also have two appearance styles: sports suit and luxury suit, and there is no obvious difference between the fuel vehicle and the pure electric vehicle. In fact, in comparison, the version of sports appearance design, especially the front face, looks more dynamic, and the design style of sports suit is not unassuming, which can be called IKEA Yishang.

　　The length, width and height are 5175/1900/1520mm respectively, and the wheelbase is still 3105mm, which is consistent with the current models. However, the side profile of the car body has been completely redesigned, and the long tail of the car is replaced by the short and smooth slip-back shape on the new model, so the whole car body posture looks more sporty, and there is no incongruity in the lengthened model. In terms of details, the luminous digital logo on the C-pillar of the new car is exclusive to the domestic version of the car, and this logo will flash on the i5 according to the charging state.

　　When we arrived at the rear of the car, the brand-new model adopted a simple design scheme. The horizontal visual effect of the car was highlighted by horizontally stretching the elements such as headlights and decorative strips, and the three-dimensional and stylish surrounding made the young movement more in place.

　　The interior design scheme of BMW 7 Series has also been applied and evolved on the brand-new 5 Series. The interactive atmosphere light strip similar to 7 Series can even be displayed in different colors and regions on BMW i5. In addition, the continuous screen design of 12.3-inch instrument and 14.9-inch central control panel makes the visual effect in the car full, and it will feel like a small 7 Series when sitting in the front row.

　　In the central control area, you can see a large number of design schemes from the family flagship, such as the crystal-cut iDrive control knob and a large number of touch buttons, which have created a good sense of advanced for the front passengers.

　　With the addition of the central control system of BMW OS 8.5, it can be said that BMW, an old-school car company, has a higher strength than the new forces in intelligent interaction. In addition to natural semantic recognition, this car can also recognize the driver’s body language and "eyes" through the camera to control the vehicle. At present, on the highway or closed road, the driver assistance system of BMW i5 can visually confirm the initiative lane change overtaking through the driver’s eyes, which is quite interesting. We also look forward to the actual test drive experience of this function. In the aspect of V2X car networking, this generation of BMW 5 Series models can interact with BMW models equipped with V2X function in real time, and vehicles can receive and display danger warnings from other BMW cars, predict parking spaces at destinations and so on.

　　In order to meet the car demand of customers in China, the iDrive 8.5 system of BMW i5 also integrates the function of WeChat car version exclusive to China, and further integrates into the WeChat ecology, so that it is convenient to use WeChat to communicate with friends in the cabin, or receive navigation and positioning information through WeChat car, and directly navigate by car navigation system.

　　In the rear entertainment system, although the rear comfort configuration of the BMW i5 is not as rich as that of the Big Brother 7 Series, the suspended giant screen that is in the same strain as the 7 Series overhead is not absent. The 31-inch floating screen with a height of 8K attached to the 7 Series is definitely a sharp weapon to attract everyone’s attention. Aiming at the China market, BMW’s rear entertainment system ecology not only involves the iQiyi platform, but also introduces Huawei application market, providing rich entertainment.

　　In terms of power, i5 adopts BMW’s self-developed excitation synchronous motor, and BMW is also the only luxury car enterprise that uses excitation synchronous motor at present. The unique brush module of excitation synchronous motor has long life, high efficiency and quiet performance, and it can also show superior acceleration performance in the middle and high speed sections compared with permanent magnet synchronous motor. The domestic i5 is equipped with the fifth generation eDrive technology. The BMW i5 eDrive35L has a maximum power of 210 kW and a maximum torque of 410 Nm. The battery is a ternary lithium battery with a capacity of 79.05kWh and a CLTC pure electric cruising range of 536km. At the same time, the maximum power of the i5 M60 is 442 kW, and the peak torque is 795 Nm, which is equivalent to that of the previous generation BMW M5 model. The acceleration time of the dual-motor four-wheel drive model from 0 to 100 km/h is 3.8 seconds, which is the characteristic of the new generation i5 M series model. In addition, the user can activate the Sport Boost function at any time through the paddle, and instantly get an additional 30 Nm of torque output.

　　In terms of charging, i5 can achieve a maximum charging power of 200kW under the BMW Super Charging Station, and the 10-80% charging time is about 32 minutes. At present, about 50 overcharging stations have been implemented, covering 17 cities in China. At the same time, in the first half of 2024, BMW will launch a DC smart charging wall box, which uses DC charging technology to support the highest charging power of 22kW, greatly improving the charging speed of household piles.

　　As an electric vehicle, the driving pleasure of BMW i5 is still the constant pursuit, which is even worse than that of the fuel version 5 Series. For example, the integrated braking system can shorten the braking distance by up to 20%, and there is a 9th generation lateral dynamics management system, which makes the cornering control stronger, and the steering can be more fun between calm and relaxed than the variable electric power steering system. Suspension, equipped with further optimized double wishbone double ball front suspension and multi-link rear suspension, taking into account the flexibility of control and comfort of riding.

　　On the i5, the delicate adjustment also brings more feedback of driving pleasure, including multiple driving modes, single pedal mode in B gear, and new Sport Boost function, which can be activated at any time through the paddle on the left side of the steering wheel, bringing an additional torque output of 30 Nm. At the same time, there is a long battery life mode, which can maximize battery life when the battery is low.

　　In the aspect of intelligent driving assistance system, the "safety first" man-machine co-driving allows users to have a clear use boundary, and BMW i5 applies attention monitoring system and capacitive sensing steering wheel. For example, BMW i5 is equipped with an automatic lane change function with line-of-sight confirmation. When the driver’s line-of-sight is confirmed, the vehicle can automatically overtake within the speed range of 60-180 km/h.. Moreover, the intelligent driving assistance system has been greatly updated and localized for the characteristics of China market, the road conditions in China and the driving habits of users.

● Competing models

Mercedes-benz EQE』

"Weilai ET7』"

　　Just as BMW 5 Series and Mercedes-Benz E-Class are old rivals, BMW i5′ s rival is indispensable to Mercedes-Benz EQE. As a Mercedes-Benz EQ family model, it has adopted a more unique design concept and its endurance performance is more advantageous. Of course, i5, as a latecomer, has also performed well in various new technologies. Of course, as an electric vehicle, we have to face the new forces in China, such as Weilai ET7 at this price. No matter the product strength or the service experience brought by the new forces, it is also the pressure that BMW i5 has to face.

● Edit Comment:

　　With the arrival of the BMW i5, BMW has further entered the era of intelligent electric vehicles. At least Series 3, 5 and 7 have pure electric vehicles. On the i5, we have seen the technological progress and the pursuit of driving interest regardless of oil and electricity. We have also seen BMW’s follow-up in the corresponding supporting services such as super charging stations. Traditional luxury brands such as BMW are making efforts to follow up in the new energy market. What do you think, can you break the new energy pattern and can BMW i5 become your pure electric choice? See you in the comments section! (Text/car home Chen Chi)

The Standing Committee of the Political Bureau of the Communist Party of China Central Committee meeting of the Communist Party of China pointed out that "speeding up the construction of new infrastructure such as 5G networks and data centers" has aroused great concern from all walks of life. Traditional infrastructure refers to railways, highways, bridges, water conservancy projects and other large buildings, which is often referred to as "Iron Gong Ji". The "new infrastructure" refers to the infrastructure construction focused on science and technology, covering 5G, artificial intelligence, industrial Internet, etc., with a wider scope, which can better reflect the characteristics of the digital economy and better promote the economic transformation and upgrading of China.

What does "new infrastructure" mainly include? Where is the "new"? What is the important role in stabilizing the economy? What changes will it bring to social development and the lives of ordinary people?

The importance of big data centers has become increasingly prominent.

In the era of mobile Internet, data traffic is increasing. Last year, the average monthly traffic of mobile Internet users in China was 7.82GB, 1.69 times that of 2018, and enterprise data also showed explosive growth. However, at present, less than 2% of enterprise data is stored, of which only 10% is used for data analysis. This shows that there is a big gap in China’s data storage and utilization capacity. In this context, the importance of big data center, namely IDC, has become increasingly prominent. Big data center is the center of data storage, processing and interaction, and is considered as one of the new infrastructures at present. Wang Peng, vice president of CCID Research Institute of the Ministry of Industry and Information Technology, said that especially during the COVID-19 epidemic, some new Internet business models emerged, and the importance of big data centers was further enhanced. "These business models are driven and supported by technologies such as the Internet and artificial intelligence. In this process, there will definitely be more data flowing on the Internet, whether it is structured, such as usual data statistics, reports, etc., or unstructured, like video and audio, data is generated in large quantities, more and faster than in the past, so the importance of big data centers is further enhanced." Wang Peng said.

Big data centers have huge room for development.

The data shows that at present, 40% of IDC cabinets in the world are in the United States, and only 8% in China, while the number of Internet users in China is obviously more than that in the United States, which means that there is a lot of room for the development of big data centers. Wu Hequan, an academician of China Academy of Engineering, predicts that the cumulative IDC market in China will exceed 1 trillion yuan from 2020 to 2025. He said: "The construction of a big data center is a long industrial chain, including servers, routers, switches, optical modules, as well as power supply, software, networks and computer rooms. In addition, for the IDC industry chain, what is more important is IDC integrated operation and maintenance, as well as’ cloud service providers’ and solutions. "

From a global perspective, technology giants such as Google, Microsoft, Amazon, Apple, and Facebook are all vigorously building big data centers and investing heavily. A data center planned to be built in South Korea will also set a record for the largest local private investment. The number of servers in some super-large data centers is usually more than hundreds of thousands, but the server room is not the most "burning money" place. "In fact, the computer room only accounts for more than 10% of the investment in the big data center, and the greater investment is in the power supply system. It must ensure very reliable power supply and ensure that the efficiency of the power supply is quite high. Another big investment is in the refrigeration system, which requires sophisticated air conditioning. In addition to power supply and refrigeration, there are also investments in lightning protection, security, disaster recovery, environmental monitoring, and integrated wiring. " He Hezhen said.

Where is the "new" big data center?

In recent years, with the development of cloud computing, big data centers have been upgraded to "cloud data centers", which are characterized by highly virtualized servers, storage, networks and applications, and users can call various resources as needed. The data center has gradually become a universal "granary" for big data, cloud computing, industrial Internet and artificial intelligence. "The new generation of information infrastructure is not only a new infrastructure, but also a strategic emerging industry. It is also a new market for information consumption. It is also a general supporting technology for new infrastructure in other fields and a new engine for digitalization of traditional industries." He Hezhen said.

At present, China’s data center construction has blossomed everywhere, and many cities have formulated data center construction plans and introduced a number of preferential policies. According to the statistics of China ICT Institute, the number of IDC racks in China is expected to increase to 3.26 million in 2020.
