　　Friendly reminder:I hope enthusiastic netizens can photograph the spy photos of your new car and send them to our corresponding mailbox: diezhao@autohome.com.cn. I look forward to your letter and become a member of the "spy".

　　　In terms of appearance, the new car follows the design of the new generation BMW 5 Series as a whole. Unlike the current models, the new car has a sharper line design, which outlines a more distinct sense of edges and corners. In the front part, the new car still adopts the kidney-shaped front grille design, and the champagne gold elements are integrated around the grille and the front enclosure, which plays a very good role in embellishment. At the same time, we can also see similar designs at the rim. In addition, the new car has simplified the angel eye headlights to make them more in line with the minimalist aesthetic trend of the current era.

　　　Coming to the side of the car, the new car has a very stretched visual experience, inheriting the elegant temperament of the BMW 5 Series. In the rear part, the new car will adopt a highly recognizable taillight design and incorporate L-shaped chrome decoration, highlighting the luxury attributes of the vehicle.

　　In a list of popular amusement facilities obtained by The Paper reporters, such projects as Rainbow Slide, Air Drifting, Tubular Slide, Glass Plank, Glass Bridge and treading on thin ice are collectively called "online celebrity Series" because they are all emerging amusement projects that have become popular on the Internet in recent years through short video and live broadcast platforms such as Tik Tok and Weibo, and their play experiences are quite exciting.

　　A list of "online celebrity Series" amusement facilities provided by an amusement equipment manufacturing company in Guangzhou.

　　The high-altitude swing was once a part of it. In 2018, an 18-meter cliff swing was opened in a theme park in Chongqing, attracting countless tourists to punch in. There are even more British media with "Do you dare to try? China set up a giant swing with a 60-foot rope on the edge of a 1000-foot cliff! ",lamenting that this is" the biggest swing in history ".

　　However, only in the past year, the high-altitude swing in this scenic spot seems to be in trouble.

　　On August 18, 2019, in this scenic spot in Chongqing, when tourists experienced the 18-meter high-altitude swing, the swing should have been raised to the highest point and then dropped. However, as can be seen in the video materials, it seems that the swing falls early before it reaches the highest point, which causes the tourists to encounter severe bumps during the downward swing, which is very shocking.

　　Although the tourists were unharmed, it seems that the fate of the high-altitude swing is changing.

　　High-altitude swing, the whole person swings in the air hundreds of meters high, which is thrilling and exciting. source map

　　"The high-altitude swing is now under supervision, so it is best not to do it, and it may be demolished in the future." The reporter consulted a recreation equipment manufacturing company in Zhongshan, Guangzhou as a "buyer", and the staff of the other party replied.

　　The staff said that because of the policy changes, the high-altitude swing seems to have been "in the cold palace", and which scenic spot or paradise will be engaged may not be worth the candle. At present, those that have not been "managed" and are being "loved" by tourists are the amusement facilities of glass projects such as glass plank roads and glass slides.

　　According to incomplete statistics, in the past three years, China has opened more than 60 glass plank roads. Open Ctrip App, and you can also search for the "Selected List of Glass Planks", which counts 30 scenic spots with glass plank roads in China, among which the famous ones are Tianmenshan glass plank road in Zhangjiajie, Baishishan glass plank road in Baoding, Yellow River 3D glass bridge, Yalong Bay Tropical Paradise Forest Park glass plank road and so on.

　　The reporter once experienced the local "5D" glass overpass in a scenic spot in yi county, Anhui Province during the Eleventh Period. The so-called "5D" means that an electronic screen is installed under part of the glass on the bridge body. As soon as a person walks up, it will immediately appear as if the glass is broken and make a broken sound. Although you have to pay an extra ticket to 60 yuan to experience the bridge, there are an endless stream of tourists.

　　The glass slide can be said to be the "advanced version" of the glass plank road, and some of them also incorporate the elements of water rafting and become the "glass water slide". Sliding on the transparent glass, you can not only see the beautiful cliff canyon scenery, but also experience the feeling of heartbeat, which quickly became an "explosion" on the Internet.

　　The temptation of maintenance-free and high return

　　"The glass slide is 4,500 yuan a meter, and if it is 800 meters, it will cost about 3.6 million."

　　Under the inquiry of the reporter’s "customer", a recreation equipment manufacturing company in Zhongshan City, Guangzhou, said that if a glass slide of about 800 meters is to be built, it will take about half a year before and after the project, and 3.6 million yuan is the cost of the total project, but it does not include the cost required for quality inspection.

　　When the reporter asked whether it was necessary to ask the local special equipment testing center to test the equipment after the completion, the staff said that only those under supervision needed the national department to test. "We are looking for a third-party test, looking for it nearby, and looking for it is specialized in testing. “

　　The reporter also asked questions about construction and design. The staff said that the construction party is the company’s own team, but in terms of design, the company will go to the design institute. When the reporter further asked what design institute he was looking for, the other party replied: "The design institute is a channel for our internal cooperation. You only need to know that we will deliver it with a formal blueprint and the design institute will stamp it."

　　Online celebrity glass slide data map

　　The reporter also contacted another garden plank road company in Shijiazhuang City, Hebei Province. As can be found from the official website, the company has more than 10 years of experience in the construction of slideways. From the original granite slideway and cement plank road to the popular high-altitude cliff plank road and glass plank road, the service scenic spots are all over Hebei, Henan, Shanxi, Shanxi, Hubei, Hunan, Shandong and Jiangsu.

　　The quotation of the staff of the company is "3,500 yuan per meter", which is not only much cheaper, but also "about 3 months in the construction period". The staff also said that there is no need for testing by the local special equipment testing center, and both the builder and the designer are their own teams.

　　"If you want the stamped drawings of the design institute, you have to pay extra," said the staff.

　　During the consultation, both companies indicated that both the glass trestle and the glass slipway are "maintenance-free" after completion, and only need to be cleaned regularly. Therefore, for operators, the investment threshold is lower, the approval difficulty is also small, and in addition, the return rate is also very considerable.

　　According to the interface news report, the glass bridge "Yuntiandu" in Zhangjiajie has a total length of 536 meters and a total investment of 260 million yuan. It was put into use in August 2016. At the hottest time, the daily reception limit was 8,000 people, and it was necessary to make an appointment in advance, which led to the fare being speculated by scalpers for six times; The annual passenger flow of Maren Qifeng in Wuhu, Anhui Province has been around 120,000 for more than ten years. After the completion of the glass plank road, the passenger flow reached 850,000 last year and the income reached 130 million yuan. The glass plank road at the 19th Peak in Chuanyan, Zhejiang Province is less than 100 meters, but the ticket revenue reached 70 million yuan one year after its completion.

　　In the face of such economic benefits, many large-scale scenic spots and parks all over the country have followed suit.

　　A shocking "accident"

　　In 2017, in the scenic spot of Mulan Shengtian in Wuhan, Hubei Province, tourists collided continuously in the glass slide, causing one death and three injuries. The youngest injured person was only 4 years old. Liu Yuhai, one of the injured, said in an interview with the media: "It didn’t take long for me to get scared and brake in a hurry." But as soon as he stopped, someone bumped into him from behind. Then, he flew out and hit the security net of the slide, and his head got stuck in the net.

　　In July, 2018, one tourist suffered from hemopneumothorax, two from brain trauma and 22 from fractures, and no one died. After investigation by the safety supervision departments of Huanggang City and yingshan county City, it is considered that the main cause of the accident is that the water pipe joint near the slideway suddenly falls off and tap water is sprayed into the slideway.

　　On May 1, 2019, tourists rushed out of the slide protection facilities in the playground of Taiping Town, Chengdu, Sichuan Province, killing 2 people and injuring 12 others. On January 10th this year, Chengdu Intermediate People’s Court made a judgment on the related litigation caused by the accident, and sentenced the development company to bear all the responsibilities in the accident. The reason is that the main person in charge of the development company failed to perform safety duties in accordance with the law, and the designers and welders employed in the garden equipment were not qualified. Moreover, there were no warning signs such as "No Climbing" at the ladder involved in the case, and no relevant staff dissuaded the climbers.

　　Although the glass water slides in some scenic spots are deeply loved by tourists, there are also potential safety hazards. source map

　　On June 1, 2019, in the scenic spot of Muyi Town, Lanshanwan, Hefei, Anhui Province, three female tourists were injured in their eyes, arms and heads to varying degrees while riding a glass drifting boat. On June 5th, Fozi Tourist Scenic Area in Pingnan County, Guangxi Province, due to the rapid sliding speed, tempered glass and guardrail failed to resist the strong impact, and tourists flew out after crashing into the glass slide guardrail, resulting in one death and six injuries. According to the news reports, on October 1st, at least two tourists died and more than a dozen tourists were injured in the glass slide of a scenic spot in East China. The specific news scenic spot has not been disclosed.

　　In addition to the accidents reported by the media, some netizens also shared their experiences with reporters. Netizen "Happy" told reporters: "I went out to play on National Day this year and saw with my own eyes that someone who slipped down hit his leg. Later, he couldn’t walk and was sent down."

　　Netizen "Xiaobai" said: "I have sat on this, which is really exciting. But at that time, my center of gravity was unstable, and I slipped and it was super painful. "

　　Some netizens said that in addition to these projects, the high-altitude guardrail-free stimulation project — — "treading on thin ice" also had "accidents". On October 1, 2018, a tourist experienced the "treading on thin ice" project in a theme park in Chongqing. At the moment when he reached the finish line, the safety buckle on his back fell off due to improper operation of the staff. Fortunately, the person arrived safely.

　　However, this "panic" scene was recorded by the surrounding tourists, and it caused many people to be scared after uploading it to the Internet. Many netizens questioned whether such emerging amusement facilities are safe or not.

　　All parties look forward to the early implementation of the standards.

　　As the reporter learned from the manufacturer, at present, in most areas, it seems that projects such as "glass plank road" and "glass slide" have not been formally included in the supervision category of special equipment, so in the process of its design, construction and operation, the safety supervision department with professional safety inspection equipment and professionals has not yet intervened.

　　However, in Hebei, many government departments have taken the lead in taking action against the potential problems of "high-risk projects" such as glass plank roads.

　　In March last year, many departments in Hebei Province issued a document requesting to strengthen the safety rectification of "high-risk projects" of glass plank roads (including glass plank roads, glass suspension bridges, glass slides, glass observation decks and other tourist facilities), and put forward the "four unifications", that is, all new glass trestle projects will stop being approved for filing; All projects under construction will be stopped; Unoperated projects will be suspended from business; All the projects that have been operated will be closed for rectification.

　　On April 20, 2018, the Hebei Provincial Tourism Work Leading Group issued the "Table on the Investigation of Safety Risks of High-risk Tourism Projects of Glass Trestles in the Province". According to the investigation, it is found that the glass plank road projects in 20 scenic spots in the province have some problems in varying degrees, such as "no safety assessment", "no quality inspection", "no geotechnical investigation report, so it is impossible to determine whether the anchor depth is safe" and "no effective control over the number of people on the bridge". As a result, 32 glass plank road projects in 25 scenic spots in the province were all closed.

　　On August 1, 2018, the Technical Standards for Pedestrian Glass Suspension Bridges and Glass Planks in Scenic Spots jointly organized by Hebei Provincial Housing and Construction Department, Quality Supervision Bureau, HKTB and Safety Supervision Bureau was officially promulgated. It is understood that this standard is the first local standard in China that specifically regulates the construction and management of pedestrian glass suspension bridges and glass plank roads in scenic spots. From the catalogue, the standard has made detailed provisions on construction materials, design, construction and acceptance, vehicle inspection and evaluation, and application of safety management.

　　Eight departments, including Hebei Tourism Commission, Safety Supervision Bureau and Development and Reform Commission, jointly issued a document saying that for glass plank road projects with complete procedures, the relevant government should organize relevant departments to organize acceptance according to Hebei Province’s "Technical Standards for Pedestrian Glass Suspension Bridges and Glass Planks in Scenic Spots", and they can only be put into operation after passing the acceptance.

　　However, in September last year, some experts proposed amendments to the standards, and the implementation of the original standards was suspended. At present, "partial revision" is being carried out.

　　On the other hand, due to the delay in the standard, scenic spots that have been suspended from operating glass plank roads, glass slides and other projects have begun to fidget and complain. According to media reports, during the National Day this year, Hongya Valley Scenic Area in Pingshan County, Shijiazhuang, which is known as the "world’s longest glass suspension bridge", suffered heavy losses because it did not open the glass suspension bridge, and its own operation was also in trouble. Therefore, the operators of scenic spots also hope that the state can introduce relevant construction standards as soon as possible and clarify the subject of supervision.

　　The glass cable bridge in Hongya Valley Scenic Area, Pingshan County, Shijiazhuang, which was completed in 2017, is called "the longest suspended glass cable bridge in the world". source map

　　On August 28th, this year, the "Professional Committee of Plank Roads and Trails" of China Scenic Area Association was established in Baishishan Scenic Area, Laiyuan, Baoding, which marked a solid step towards standardization and standardization of plank road construction management in national scenic spots.

　　On August 31st, initiated by some slipway builders, the kick-off meeting of glass slipway standard and the demonstration project of laminated glass and safety performance evaluation for CSTM glass slipway was held in Luoyang, Henan. Experts from China Special Equipment Testing and Research Institute and Cable Vernier Committee also attended the meeting.

　　No matter when the standards are issued, one thing is certain. In actual operation, the operators of scenic spots always have the responsibility to strengthen safety management functions and equip them with necessary safety protection measures.

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.

　　[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.

　　As the Palestinian-Israeli conflict enters the third week, all parties pay more and more attention to the conflict. According to CCTV news reports, on October 20, local time, US President Biden, who had just visited Israel, applied to the US Congress to pass a special budget bill, increasing the budget by 105 billion US dollars for the overall assistance programs in Ukraine, Israel and strengthening America’s own security.

　　It is worth noting that Biden’s move was put forward after his embarrassing trip to the Middle East. On the 18th, Biden arrived in Israel to visit many countries in the Middle East. However, the Ahli Arab Hospital in Gaza was attacked, and Jordan and other countries cancelled the scheduled high-level meeting. This move undoubtedly gave Biden a cold shoulder during his trip to the Middle East, and Arab countries’ dissatisfaction with Israel and the United States was also evident.

　　Multinational leaders cancel meeting with Biden

　　According to Xinhua News Agency, Jordan announced in the early morning of October 18th that it would cancel the meeting of the leaders of Palestine, Jordan, Egypt and the United States scheduled for that day in Amman. Earlier, the Palestinian Foreign Ministry issued a statement saying that Israeli warplanes attacked the Ahli Arab Hospital (also known as Baptist Hospital) in the Gaza on the evening of 17th, while the Israeli military said that Israel had intelligence that rockets from the Palestinian Islamic Jihad (Jehad) mistakenly hit the Gaza Baptist Hospital. However, Jehad denied the Israeli allegations.

　　After the attack on the Gaza hospital, the National Security Council issued a statement saying that the US government believed that the Israelis were not responsible for the incident. During his visit to Israel, Biden also promised Israeli Prime Minister Benjamin Netanyahu that the United States would continue to support Israel.

　　Biden’s attitude caused dissatisfaction among Arab countries. According to the Global Times, Biden’s previous itinerary included a visit to Jordan after his visit to Israel, and a meeting with the King of Jordan, the Egyptian President and the Palestinian President at a summit in Amman, Jordan, to discuss how to ease the situation between Palestine and Israel. However, the attack on the Gaza hospital and the United States’ position of favoring Israel caused public anger in Arab countries, and the three countries announced that they would cancel their meeting with Biden.

　　Abdel-Khalek Abdul Khaleq Abdulla, a retired professor of political science and a member of Emirati Thinkers in the United Arab Emirates, pointed out that Arab countries were shocked by Biden’s position of "protecting" Israel. "Now I feel that the United States is an accomplice in various crimes against Palestinians." He added, "Arab countries are now trying to ignore Biden and avoid meeting him."

　　The Jordanian government also issued a statement saying that the summit will be rescheduled after all parties agree to end the "massacre of Palestinians". "It is not good for anyone to hold a summit at this time, and it is not good for the end of the war, so we decided to cancel this meeting." Ayman Safadi, Jordan’s foreign minister, said.

　　Protests broke out in many countries in the Middle East.

　　Many countries in the Middle East have expressed strong dissatisfaction with the attack on Al-Ahli Arab Hospital in Gaza. Egyptian President Abdel Fattah al Sisi expressed strong concern and condemnation of the attack on the hospital. King Abdullah II of Jordan strongly condemned the Israeli air raid on the hospital in Gaza and warned that the current Palestinian-Israeli conflict "has entered a dangerous stage". Queen Rania Abdullah of Jordan posted on social platforms that she was "shocked" by the explosion.

　　"This massacre is a war crime, an insult to mankind and a stain on the world conscience." Turkish President Recep Tayyip Erdogan called the attack "the latest example of Israel’s lack of the most basic human values in its actions".

　　In addition to official statements, protests and rallies broke out in many countries. People from Iraq, Iran, Egypt, Syria and other countries took to the streets to launch protests against the United States and Israel. The embassies of the United States and Israel in Lebanon, Jordan and other countries were also surrounded by the assembly crowd. Protesters used various slogans to express their anger against Israel, and many diplomatic institutions in the United States and Israel were even set on fire. Anger even spread to North Africa, and protests against the United States and Israel took place in Tunisia, Morocco and Libya, with thousands of people participating.

　　"Against occupation! Say no to the United States! " Tens of thousands of Iraqi protesters gathered in Tahrir Square in Baghdad, waving the flags of Palestine and Iraq, and a huge Israeli flag was placed on the ground for protesters to trample on.

　　The same thing happened in Iran. Thousands of Iranians gathered in the capital Tehran, holding the flags of Palestine and Hezbollah and shouting slogans to show their support for Palestine. In Jordan, thousands of people gathered around the Israeli Embassy in Amman. People took to the streets to condemn Israel’s continuous bombing of the Gaza Strip, and protesters tried to attack the Israeli Embassy. Jordanian police had to use tear gas to disperse them.

　　Us "safe passage" proposal attracts dissatisfaction from Jordan and Egypt

　　In addition to the attack on Gaza Hospital, the proposal of "safe passage" in the United States is also one of the reasons why countries in the Middle East have lost enthusiasm for Biden’s visit. Egypt and Israel border on Palestine, and both countries strongly oppose the U.S. plan to establish a safe passage for Palestinians fleeing from Gaza on the Sinai Peninsula in Egypt bordering Gaza.

　　Since the escalation of the Palestinian-Israeli conflict on October 7, the United States has been trying to discuss with Jordan and Egypt about the establishment of a "safe corridor", but the implementation of the plan has been frequently blocked because of the interests of all parties involved. Biden once said that during his visit to Israel, he talked with Egyptian leaders to discuss the opening of Rafah port for material transportation and personnel evacuation, but in the end, Egypt only agreed to the proposal of restarting the port to transport humanitarian relief supplies.

　　The proposal of the United States to establish a "safe passage" has aroused anger in the Arab world. According to analysis, it is very likely that Israel will reduce the Palestinian population in the Gaza by this way, so as to reoccupy the Gaza Strip and make the Palestinians homeless again, making it difficult for them to return home. King Abdullah II of Jordan said that neither Jordan nor Egypt would accept refugees from Gaza, and hinted that any proposal to let these two countries accept refugees from Gaza was a "common trick".

　　Egyptian newspapers commented that the idea of the United States "driving out" Palestinians from their homes this time would be a repeat of "Disaster Day in 1948", when about 700,000 Palestinians fled or were driven out of their homes in the Middle East war, accounting for about half of the total Palestinian population at that time. Egyptian President Seyce said that the presence of Gaza in the Sinai Peninsula may also make the peninsula a base for anti-Israeli militants, which will lead to Israel’s attack on Egypt and expand the scope of the war.

　　Egyptian Foreign Minister Sameh Choucairy said that just as the United States and Europe are sensitive to the influx of refugees, so is Egypt.

　　Protests and demonstrations in Washington, new york and Chicago.

　　In addition to the opposition and protests in the Arab world, many protests and demonstrations broke out in the United States because Biden’s government supported Israel’s position.

　　According to CCTV news reports, since the outbreak of the new round of Palestinian-Israeli conflict, many Americans believe that the United States’ provision of military weapons to Israel is equivalent to giving Israel "absolute freedom" to do "anything" to Palestine.

　　On October 18th, local time, many pro-Palestinian people staged protests in the area near the Capitol in Washington, D.C., demanding that the U.S. government promote a ceasefire between Palestine and Israel, and more than 350 people entered the House of Representatives office building near the U.S. Capitol for demonstrations. According to the Global Times, residents of new york, Chicago, Los Angeles and other American cities also held demonstrations on October 21st.

　　At the same time, there are more and more voices in Biden’s government that openly oppose Biden’s continued military assistance to Israel. Josh Paul, a the State Council official in charge of the Congressional Liaison Office dealing with foreign arms sales, resigned on October 18th because of the US policy of supplying weapons to Israel.

　　"I can’t support a series of major policy decisions, including throwing more weapons at one side of the conflict. I think this is short-sighted, destructive and unfair, and contradicts the values we openly support." Paul wrote in a statement.

　　The Senate controlled by the Democratic Party plans to act quickly on Biden’s proposal to provide assistance to Israel and Ukraine, hoping to put pressure on the House of Representatives controlled by the Republican Party. However, there are also differences within the Senate on how to advance. Eight Republicans, led by Senator Roger Marshall of Kansas, said they did not want to combine aid to Ukraine and Israel into the same legislation.

　　"These are two independent and unrelated conflicts. It is wrong to use aid support to Israel to try to provide additional aid to Ukraine." The above eight Republicans wrote in a letter.
