In 2024, there were many models called "7", but none of them could really carry the banner of smart cars. However, recently, a domestic "Seven Series" appeared, which showed us that "this is the ceiling of intelligent driving and voice control".

As a human being born in the last century, although he grew up with technology, he is not used to voice control, whether it is a car or a mobile phone. When we spit out how anti-human it is to cancel the physical buttons, we actually spit out the mental retardation of the intelligent car system.

Because there are only two results of using voice control, either it looks very retarded or I look very retarded, so in the era when cars at any price have voice control, almost no one can really use it without causing trouble to themselves.

Finally, a car company solved this random problem, not HarmonyOS Zhixing, but Geely and Baidu cooperated. In addition to the big model of intelligent driving, what impressed me the most was the revolutionary changes in its phonetic system. Voice not only partitions, but also cooperates with eye following, which perfectly supports fuzzy voice control.

Thanks to the support of AI technology, voice control is not retarded, and the communication between people and cars is more direct and more like the communication between people. It is also set that when someone is in the car, someone outside the car gives an instruction and does not accept it. This function is quite life-saving.

Another highlight is that it turns the hidden door handle into an invisible door handle, which will not freeze the door handle even in winter. And there is a standby power supply and mechanical switch on each door to prevent the door from crashing and being unable to open without electricity. Millimeter-wave radar is installed in every door, which can keep away from the risk of luxury cars hitting porcelain when the door is opened by voice, and it can be regarded as home.

Although screen shifting is not unusual, it is similar to Tesla model3, but the difference is that in order to prevent the uncertain danger caused by the big screen crash, Extreme Yue 07 has a set of backup electronic shifting mechanisms on the central control platform, which is quite thoughtful.

In fact, the hardware configuration of this car is not unique, and what is refreshing is the details. For example, when it is in the automatic driving stage, blue lights will light up around the car body to remind passers-by and passing vehicles not to be as knowledgeable as automatic driving. This function is very important and not difficult to realize, but no car company has done this in the past. That’s the detail.

At present, most details of Extreme Yue 07 have not been announced, including the battery life and pre-sale range, but from these details, it has defeated all smart electric vehicles before SU7 and SU7.

But I don’t think its competitors are necessarily. Because su7 takes the performance online celebrity route, although the drag coefficient of Extreme Crossing 07 is only 0.198, its selling point is not the new energy acceleration, but the revolutionary upgrade of intelligent driving. The real influence of the opponent is the upcoming listing of HarmonyOS Zhixing’s Enjoy World.

Don’t look at the administrative business route, the body is more atmospheric and more stable. However, as a product endorsed by HarmonyOS, if the product fails to reach the level of’ 07′ in terms of intelligence after listing, I am afraid it will completely lose its civilian market.

This is not a gimmick problem, but a problem of grasping the details of the intelligent driving system. Come on, HarmonyOS Zhixing. At present, apart from slogans, most of us can’t feel what you are far ahead of.

In today’s new car market, independent brands occupy the commanding heights, no matter the quantity or volume of new cars released.

According to the latest data of the Passenger Car Association, in April, the retail sales volume of the national passenger car market was 1.532 million, down 5.7% year-on-year.However, among them, the retail sales of independent brands reached 882,000 vehicles, up 12% year-on-year, accounting for 57.4% of the total market share.

butHelping independent brandsWhat is taking off against the trend is, of course, new energy vehicles..fourmoonNew energy vehicleRetail sales reached 674,000 vehicles, a year-on-year increase of 28.3%.;wholesale78.50,000Cars, an increase of 30..0%.amongIndependent brandRetail share of new energy vehicles64%,Joint venture brandnewEnergy vehicleshareforeheadhave only4.3%, differenceThe magnitude is obvious..

"Jinghua" shield machine, with a diameter of 16.07 meters, a length of 150 meters and a weight of 4,300 tons. Lying horizontally, it is even higher than five stories … It looks heavy, but it has high skills: it is a good hand at digging holes and a sharp weapon for tunnel construction, like an underground dragon, such as a "steel pangolin". The shield machine developed by Tiejian Heavy Industry, from running to leading technically, has become another "Made in China" business card after "China High Speed Rail".

Hunan Daily All-Media Reporter Cao Xian Correspondent Hu Qing

In Tongzhou District, Beijing, the west tunnel of the East Sixth Ring Road reconstruction project is under construction. On the ground, beijing-harbin railway got on the high-speed train and galloped by, but the passengers didn’t notice that a "steel behemoth" was steadily driving tens of meters underground.

On April 12, 2022, China’s largest diameter shield machine "Jinghua" successfully crossed the Jingha high-speed railway line. This behemoth plunges underground, causing no disturbance to the ground buildings, and controlling the surface settlement in millimeter level, creating a miracle of the construction of super-large diameter shield machines in China.

This "Jinghua" shield machine rolled off the production line in Changsha No.1 Industrial Park of China Railway Construction Heavy Industry Group Co., Ltd. on September 27th, 2020. Shield machine is known as "the king of construction machinery". China was once a zero foundation, and its technology and market were controlled by people. Nowadays, the domestic brand shield machine represented by China Railway Construction Heavy Industry has occupied two-thirds of the global market share.

Over the past 10 years, how did China shield machine strike back brilliantly?

1 "2 mm" see skill-

Buried in stealth, amazing years

Shield tunneling relies on many cutter heads embedded in the front circular cutter head. The cutter head rotates slowly, like a big mouth, and the cutter head is like a tooth, which "chews up" rocks and sand and transports them through the pipeline.

Shield construction is to dig tunnels under the ground, and there is no need to "open the belly" on the ground, which has little impact on road traffic. In the underground reconstruction part of Beijing East Sixth Ring Road Reconstruction Project, the tunnel shield construction section is about 7.4 kilometers long, and the excavation section size is six times that of the general subway tunnel.

"It is the first time in the world for a shield machine with such a large diameter to dig such a long distance at a time." Railway Construction Heavy Industry undertook the task of developing "Jinghua", and the R&D team faced unprecedented challenges.

The underground space environment is complex, and more than 50 risk sources are densely distributed on the ground. Super-large diameter, super-long distance, super-deep soil cover and super-sensitive environment, some authoritative people in the industry are worried: "Will domestic equipment work?"

Without two brushes, I can’t do it.

In the process of tunneling, the shield machine faces all kinds of interference caused by earth pressure, underground water pressure, mud in and out, and rocks in the way. The R&D team adopted a high-precision gas-liquid balance control technology, and an air cushion cabin was set behind the cutter head cabin, so that the pressure was indirectly transmitted instead of directly impacted. Figuratively speaking, it is the increase of pressure and exhaust; Sudden pressure drop, replenishing qi, and instantly eliminating pressure fluctuation.

"The underground’ movement’ is big, and what to do on the ground is not affected." Zhang Shuaikun, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, said that during the excavation of Jinghua, the surface settlement was always controlled within 2 mm.

By June 1, the "Jinghua" had broken through 3,668 meters, and the excavation was more than half successful. In the meantime, a new record of 542 meters in a single month was created. "Whether it is size or technology application,’ Jinghua’ has reached the world’s leading level." Zhang Shuaikun said proudly.

On the network platform, the short video about "shield machine" has been viewed by millions of people. While enjoying the convenience of cars and subways passing through tunnels, people want to know why tunnels are dug quickly and well now.

In the 1950s, China put forward the plan to build a subway in Beijing first. The first phase of the 23.6-kilometer-long Beijing subway project took more than 10 years from construction to trial operation.

Before tunnel construction in our country, the traditional manual drilling and blasting method was used to drill, shoot and dig stone slag, which cost a lot of manpower, material resources and even life. "Compared with the current shield machine that digs hundreds of meters every month, at that time, it was greedy every day, and it could not dig dozens of meters in one month." He Qiping, the 58-year-old chief technology officer of China Railway Construction Heavy Industry, has worked as a tunnel for most of his life and experienced great changes in the industry. He said with deep feeling that it would take at least 100 years to build all subway lines in China at the same speed as that of Beijing Line 1. Because China has its own shield machine, the speed of subway construction has been accelerated for more than 60 years.

Compared with the predecessors in the industry, Zhang Shuaikun, born in 1980s, is lucky. His WeChat avatar is "Jinghua", and the blank space of the photo reads: Burying your head and sneaking, amazing years. These eight words have become the best annotation of the largest diameter shield machine made in China, and also a vivid portrayal of countless hard-working scientific researchers and industrial workers.

2 From "1" to "1000+"-

The "printing machine" of foreigners has become the "competitive machine" of China people.

Seen from the satellite perspective, the super factory of Tiejian Heavy Industry in Changsha, Hunan Province is a shining new industrial landmark.

Ten years before the birth of "Jinghua", Railway Construction Heavy Industry produced the first EPB shield machine named "Pioneer 19".

"Pioneer" broke the game in one fell swoop. "Let the’ foreign shield’ with an average selling price of about 150 million yuan quickly reduce its price by 30% in China." Liu Feixiang, Party Secretary and Chairman of Tiejian Heavy Industry, said.

In the 1990s, China imported shield machines from abroad for the construction of large-scale tunnel projects. Wu Min, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, used to drive foreign equipment in tunnel construction units, and he often wondered "when can the domestic shield machine be used".

Foreign shield machines are expensive to sell and the service is more expensive. Foreign companies hold key technologies in their hands, charge high service fees, wait until working days to solve problems, and often refuse to accept the rectification and optimization suggestions of domestic contractors.

The rapid development of China is changing with each passing day. The high-speed rail and subway network are accessible, and water conservancy and mine construction are speeding up. Large-scale engineering equipment like shield machine is too important.

You can’t always be led by foreigners. In 2008, Tiejian Heavy Industry decided to specialize in customized underground engineering equipment.

Supported by the "863" project of the Ministry of Science and Technology, in 2012, China Railway Construction Heavy Industry launched an attack on the first domestic rock tunnel boring machine (TBM). Different from the shield machine that eats soft rock and gravel, the rock tunnel boring machine takes hard rock as the "next meal", which is also the weak link of the autonomy and localization of tunnel boring equipment in China.

Knowing this news, Wu Min gave up his job with higher income at that time and devoted himself to the development of the first domestic TBM.

From scratch, grope forward. For twenty or thirty big parts such as cutterhead, shield, main beam support and propulsion, a research team is set up for each part. Every data is accounted for over and over again, and it is pushed over and over again. More than 3,000 mechanical drawings have been audited.

At the end of 2014, the first domestic open TBM was rolled off the assembly line of China Railway Construction Heavy Industry. In participating in the construction of water supply project of Jilin Province, the highest monthly footage of this TBM reached 1,209.8 meters, and the bid was completed more than one year ahead of schedule, leaving the foreign brands that competed in the same field and ranked first in the world at that time far behind. "Very uplifting!" Wu Min is quite proud of this product.

Today, there are 40 shield machine production lines in Changsha No.1 and No.2 Industrial Parks of Railway Construction Heavy Industry, which has become the largest underground engineering equipment manufacturing base in the world. Over the past 10 years, more than 1,000 roadheader machines have been sent from here. The shield machine, once regarded as a "printing machine" by foreigners, has now become a "competitive machine" for China people.

Great country heavy weapon serves great country project. The western water conservancy project, with a maximum buried depth of 2268 meters, is all over the altered rock belt. The variable diameter open TBM solves the "stuck machine" problem that plagues the world excavation industry and successfully breaks through the barrier. In the Pearl River Mouth Tunnel of Shenjiang Railway, "Shenjiang No.1" advanced to the depth of 106 meters, helping to build a half-hour living circle in Guangdong-Hong Kong-Macao Greater Bay Area …

3 From "Apprentice" to "Teacher"-

China equipment accelerates the equipment world.

In the early summer, on the west bank of Xiangjiang River in Changsha City, the super-large diameter shield machine "Xingsheng" is being debugged, and the trip across Xiangjiang River will be started soon, which will help alleviate the traffic bottleneck in the central city of Changsha.

From Beijing to Changsha, Railway Construction Heavy Industry has developed 6 sets of shield machines with super-large diameter of 15 meters and above. The core technology of shield machine in China has become more and more mature and powerful.

Shield machine integrates advanced technology in many fields, such as machinery, electricity, liquid, light, control, engineering, etc. Its manufacturing process is complex, and its degree of autonomy directly reflects the industrial level and industrial chain perfection of a country.

Size, there are "super" and "tiny". A shield machine with a diameter of only 0.5 meters, "the sparrow is small and complete."

Technology, from running to part leading. Horizontal excavation, vertical shaft, inclined shaft, various modes and special-shaped sections are not a problem.

Market share from supporting role to leading role. The output of rock tunnel boring machine of China Railway Construction Heavy Industry has been the first in China for five consecutive years. The domestic brand shield machine represented by China Railway Construction Heavy Industry has climbed to more than 95% in the domestic market share, accounting for two-thirds of the global market share.

People have no me, people have my advantages, and China roadheader strode out of the country.

In 1950s, Soviet experts came to China to help Beijing plan the first subway line. Sixty years later, five shield machines from China Railway Construction Heavy Industry participated in the construction of the southwest section of the third interchange ring road of Moscow Metro, and were affectionately called "five golden flowers" by the locals.

The "Five Golden Flowers" proudly bloomed in snow, which overcame the extremely cold environment of minus 30 degrees Celsius, set a new record for local subway construction and became a model for overseas construction of shield machines in China.

On the eve of the Spring Festival in 2022, after more than seven hours of overseas connection, Railway Construction Heavy Industry finalized cooperation with an Italian construction company. China shield machine is about to enter the Italian market for the first time.

"Hundreds of technical parameters are compared one by one, and the attitude of the other party gradually changes from distrust to trust." Zhong Qing, an engineer from the Research and Design Institute of Railway Construction Heavy Industry Roadheader, said that China shield machine has comprehensive advantages in terms of price, performance, quality and service, and is more competitive than foreign brands. He said with emotion, "I used to be a teacher, but now I am a teacher." In less than 20 years, the change is too great. "

The reporter walked into the assembly workshop of Railway Construction Heavy Industry, but saw a shield machine being hoisted and tested in an orderly manner. The base label showed that the destination was Sri Lanka, India and Singapore. In the first quarter of this year, the amount of new overseas contracts signed by Railway Construction Heavy Industry increased by 9 times year-on-year.

Along the "Belt and Road", China equipment accelerates the equipment world. In 2021, Tiejian Heavy Industry ranked among the top 30 global construction machinery manufacturers and ranked first among the top 5 global full-face tunnel boring machine manufacturers.

Move the classroom into the workshop

I have a "billion-point" heart.

Deng Kangwei (a junior majoring in urban underground space engineering in Central South University)

It is accidental to choose the major of urban underground space engineering. On the weekend of my freshman year, I read several books related to urban underground space in the library and learned that the use of above-ground space is becoming increasingly saturated, and underground space will become the "main battlefield" for urban construction. So, when I subdivided my major, I chose this major.

This semester’s professional courses often talk about shield machines. As a young observer of Hunan Daily, I came to Tiejian Heavy Industry to observe the shield machine at close range. For me, it is like moving the classroom into the workshop and learning the principle and structure of the shield machine in front of books and drawings in class. It is a completely different experience.

It took me six hours to assemble the toy of shield machine building blocks presented by the enterprise, so I can experience the fun of "manufacturing" a shield machine. In fact, there are more than 30,000 large and small parts on a shield machine. From conventional diameter to the development of super-large diameter shield machine, technicians have devoted themselves to tackling more than 2900 days and nights.

I was deeply impressed by this statement that the shield machine has changed from a "printing machine" for foreigners to a "competitive machine" for China people. Scientific researchers have gnawed at the "hard bones" of core technologies, and industrial workers have developed the hard skills of striving for perfection, so that China’s independent research and development of shield machines is no longer subject to people, from zero foundation to mastering key core technologies, leading the world.

Walking into the super factory of shield machine, I saw the big scene of shield construction and became a "shield driver" as I wished. This "immersive experience class" made me feel the innovative power of hard-core technology, which made me feel "a little bit" and made a different plan for the future.

Urban underground space contains unlimited development space, and the future awaits us to change and create with broader knowledge and broader horizons.

　　CCTV News:The 2021 Global Industrial Internet Conference closed yesterday (October 19th). This Global Industrial Internet Conference also showed many latest technologies of "5G+ Industrial Internet". At present, there are more than 1,800 "5G+ Industrial Internet" projects in China, and the mining, electronic equipment manufacturing, equipment manufacturing and other industries have achieved remarkable results, accelerating the digital transformation of traditional industries.

　　Liaoning has 75% of the country’s magnesite resource reserves, but the power consumption per ton of magnesite products is about 3000 degrees.

According to Ukrainian media reports, the Ukrainian National Security Agency said on the same day that it could not confirm or deny its participation in the car bombing.

　　　　The National Day Golden Week is coming, and the auto market will also usher in a small climax of rising sales. The Geely Global Hawk GX7 2.4L, which was released at Chengdu Auto Show, won the favor of many consumers immediately after it went on the market. The reason is not only because it only sells for 119,900 ~ 129,900 yuan, but also because it is equipped with the advanced power combination of CVVT engine and +6AT transmission. With such a high cost performance, this car will undoubtedly become the focus of the 11th sales season!

　　　　6AT automatic manual transmission, the best handling experience of the same class car.

　　　　As the first autonomous SUV equipped with 6AT transmission within 150,000 years, this killer will bring a very high purchase index to the Global Hawk GX7. This 6AT comes from DSI Australia, the second largest transmission manufacturer in the world. With the widespread adoption of 4AT in its class, Geely Automobile broke the monopoly of joint venture brand on 6AT, and GX7 far surpassed its class in terms of handling, performance and fuel consumption.

　　　　With the addition of 6AT with two transmission ratios, the gear ratio between gears is more reasonable, which makes the whole shift process smoother and smoother. At the same time, the setting of more gears makes the gear ratio range wider, which not only effectively suppresses the body shake at the start, but also reduces the engine speed during high-speed cruising, which significantly improves the fuel economy. The shift response of this transmission is only 0.3 seconds, which greatly reduces the power loss caused by shifting, and makes the start acceleration more rapid. Overall, the 6AT of Global Hawk GX7 is the best in its class in terms of comfort, handling and fuel economy.

　　　　2.4L CVVT engine, giving consideration to power and fuel consumption.

　　　　The engine compartment of the Global Hawk GX7 embodies the mature and perfect assembly technology of Geely Automobile. The engine compartment is arranged neatly and orderly, and the engine is equipped with a plastic cover. The model of this 2.4L engine is JLD-4G24, which is independently developed by Geely. The maximum power is 119kw and the maximum torque is 220N&bull. M, the parameters are in the mainstream level in the same class car, and with the cooperation of 6AT with excellent transmission, it can bring 10% power improvement.

　　　　Although most independent manufacturers are weak in the research and development of large-displacement engines, Geely once again uses technology to justify its own cars. This engine adopts aluminum cylinder block and CVVT technology, which can control the closing time of intake valve to increase air intake, make gasoline burn more fully and improve engine efficiency. Generally speaking, this engine has achieved a good balance in terms of power and fuel economy.

　　　　At present, there are two models of GX7 2.4L: 119,900 comfort model and 129,900 administrative model. The latter is more abundant in airbags and multimedia equipment than the former, with skylight and seat heating. Consumers who want to experience the extraordinary control experience of CVVT+6AT can choose the comfort type, while consumers with higher comfort requirements can choose the executive type. For the autonomous SUV at this price, the scientific and technological value of Global Hawk is the highest at the same level. I believe no one can resist the temptation of CVVT+6AT.

CCTV News:In recent years, while the application of algorithms has injected new kinetic energy into economic and social development, the unreasonable application of algorithms such as algorithm discrimination, "killing big data" and inducing addiction has also brought troubles to our lives. In response to these problems, the "Regulations on the Administration of Internet Information Service Algorithm Recommendation" jointly formulated by the National Network Information Office and other four departments was officially released on January 4, which extended a "sword" to various algorithmic chaos.

It is clear in the Regulations that the application of algorithm recommendation technology refers to providing information to users by using algorithm technologies such as generating synthesis class, personalized push class, sorting selection class, retrieval filtering class and scheduling decision class. This means that all kinds of Internet companies that provide algorithm recommendation services are almost within the scope of supervision, such as various short video platforms, e-commerce platforms, social platforms and catering take-out platforms.

Guarantee the user’s algorithm knowledge and choice.

The "Regulations" require that users’ right to know and choose algorithms should be guaranteed, and users should be provided with options that are not aimed at their personal characteristics, or the option to conveniently close the algorithm recommendation service.

Zuo Xiaodong, Vice President of China Information Security Research Institute:Using algorithm recommendation can customize different information and services for individuals, which has two risks. The first is the risk of user personal information protection. Platform operators may illegally collect and abuse citizens’ personal information. The second is the risk of algorithm manipulation. Because the information received by each of us and the services we use are customized by Internet platform operators, it may also lead to public opinion security risks. Therefore, it is necessary to strengthen algorithm recommendation, which is not only the need to safeguard citizens’ personal rights and interests, but also the need to safeguard national security.

Prohibit "big data killing" to protect the legitimate rights and interests of consumers

In response to the "big data killing", the "Regulations" propose that unreasonable differential treatment should not be implemented on trading conditions such as trading prices by using algorithms according to the characteristics of consumers’ preferences and trading habits.　　

The "Regulations" clearly stipulate that information that may cause minors to imitate unsafe behaviors and violate social ethics, induce minors’ bad habits and other information that may affect their physical and mental health shall not be pushed to minors, and algorithmic recommendation services shall not be used to induce minors to indulge in the Internet.

Zuo Xiaodong, Vice President of China Information Security Research Institute:The platform deliberately pushes specific information to minors. For example, if you know that you like reading horror novels, push them one by one.

For the elderly, it is required that the algorithm recommendation service should fully consider the needs of the elderly for travel, medical treatment, consumption and work, and should facilitate the safe use of the algorithm recommendation service by the elderly.

Improve the platform dispatching service to protect the rights and interests of workers

Before the promulgation of the Regulations, some take-away platforms used algorithms to measure the delivery time of take-away workers, which caused social controversy. The unreasonable algorithm mechanism once made take-away riders labeled as the most dangerous occupation. In view of this phenomenon, the "Regulations" proposed that relevant algorithms such as platform order allocation, remuneration composition and payment, working hours, rewards and punishments should be established and improved.

Zuo Xiaodong, Vice President of China Information Security Research Institute:Some platforms treat workers differently, and some riders earn more today, so when sending orders again, they deliberately send him a list with a long distance and low price to control his income that day.

Protecting data security, the network security review method is coming.

Another new regulation released on January 4 also focuses on maintaining data security. In order to implement the Data Security Law and other laws and regulations, 13 departments including the National Network Information Office and the National Development and Reform Commission revised and issued the Measures for Network Security Review, and the revised Measures came into force on February 15, 2022.

Network security review is required when users’ information exceeds one million to go public abroad.

According to the relevant person in charge of the National Network Information Office, the "Measures" include the situation that the data processing activities of network platform operators affect or may affect national security in the network security review, and clarify that network platform operators who have personal information of more than 1 million users must apply for network security review when going public abroad.

Zuo Xiaodong, Vice President of China Information Security Research Institute:The purpose of the review is to prevent key information infrastructure from being controlled, prevent core data, important data and a large amount of personal information from being stolen, and prevent network information security risks.

Guard against data security risks and protect national security

The Measures require that when key information infrastructure operators purchase network products and services, they should predict the possible national security risks after the products and services are put into use. If it affects or may affect national security, it shall report to the network security review office for network security review.

Zuo Xiaodong, Vice President of China Information Security Research Institute:For ordinary users, we should be aware that data security has become an important part of national security, and we should pay attention to preventing data security risks and fulfilling data security protection obligations.

China has continuously strengthened the construction of data security laws and regulations.

In recent years, China has continuously strengthened the construction of laws and regulations on network security and data security. Last year alone, two laws and one regulation were promulgated and implemented. On September 1, 2021, the Data Security Law and the Regulations on the Security Protection of Critical Information Infrastructure were officially implemented; On November 1, the Personal Information Protection Law was officially implemented.

Zuo Xiaodong, Vice President of China Information Security Research Institute:The two regulations issued today are the implementation of the provisions of the superior law, which shows that China’s laws and regulations system in this area has been continuously improved and improved, and there is a more adequate legal basis for safeguarding national network security and data security.

[CCTV Short Comment] Cultivate a vibrant ecology with the awareness of pipe network according to law

Modern life is inseparable from the Internet, and the benefits and disadvantages brought by the Internet are affecting us in reality. Then we must formulate sound rules for the development of the Internet, including criminal and civil legal provisions, including the red line of national security and public safety, including values that do not violate ethics, including the economic model that does not harm fairness and justice. In short, people should not feel that they dare to do things online. China has the largest network users in the world, and it is also forming the most impressive network economy system in the world. We must put the development of the Internet into the track of laws to follow, laws to be observed, law enforcement to be strict, and offenders to be prosecuted, and cultivate a vibrant and thriving network ecology with the awareness of building a pipe network according to law.

Automobile Quan Huafu News At the end of 2023, there was an important model quietly listed in a controversy, which was Chery’s high-end new energy model-Xingtu Xingjiyuan ES. But before the Spring Festival in 2024, Xingtu New Energy added a new car: Xingjiyuan ET. In this way, the star-to-star era sequence has formed the lineup of Gemini models of cars ES and SUV ET.

Today, the model we test drive is the pure electric four-wheel drive version of Star Era ET, with the maximum power of 353kW and the maximum horsepower of 480 horsepower. The curb weight has reached 2339kg, the body size is 4955/1975/1698mm, and the wheelbase is 3 meters. Star Era ET battery pack is Contemporary Amperex Technology Co., Limited, and the wheel hub size reaches 255/50 R20. The size, space and power of the whole vehicle are enough to see and use.

Wild and hard enough to go out and play without any worries.

Accidents always come unexpectedly. At the beginning of the test drive meeting, it was actually a direct hard-core cross-country, opening the shoal and wading! It’s the first time to drive a new energy SUV across the river. I directly turned on the off-road mode of Star Era ET and slowly tried to drive the car into the river.

The feeling and sound of a behemoth with a weight of 2.3 tons pressing on the pebbles at the bottom of the river make driving gradually enter the state. According to the test drive coach, the wading depth of Star Age ET is 750mm, which is more than that of Bobcats.

After wading, there are conventional hard-core cross-country venues, bullet pits and cross-axle pavements. However, there is no pressure on medium and large SUVs such as Xingjiyuan ET. In the whole process, the torque at the wheel end of Xingjiyuan ET is distributed in place, and the wheels are locked as soon as they slip, and the support of the suspension is very tight. It can be seen that Chery Automobile’s "cloud structure" plays a decisive role in the adjustment and promotion of the whole vehicle.

Big enough and comfortable enough, and it is easy and comfortable to travel at home.

Having said that, the positioning of Star Era ET is, after all, an urban mobility SUV. After off-road measurement, the off-road capability of Star Era ET has made people worry about nothing, but what about the comfort and space of positioning home cities for mobility?

The wheelbase is 3 meters and the body size is close to 5 meters. Such parameters can be imagined in the interior space. Whether in the front row or the back row, the head space and leg space are more than enough, and the flat floor in the back row is also frequently praised by the teachers who participated in the test drive.

In the front cab, Star Age ET is equipped with the main zero-gravity passenger seat of the model. The support of the seat to the body is in place, which makes the human body feel comfortable. In fact, the armrest box is also a highlight, which can be moved back and forth for a certain distance.

Auto Quan Huafu Review: At present, Star Era ET only has 5 seats. For new energy vehicles of this size, 6 seats and 7 seats can actually be added later. Moreover, the official logo, in the second quarter of this year, Star Era ET will usher in an extended-range model, so that people with pure battery life anxiety have more choices.

The host lineup of CCTV Spring Festival Evening in 2015 was announced.

In addition to tradition, this year’s Spring Festival Gala emphasizes that creativity keeps pace with the times, and under the background of diversified integration in the information age, cross-border mashups have changed from different styles to the style of the times, so it is natural for the Spring Festival Gala to catch up.

In 2014, the divine comedy "Little Apple" was mixed with Phoenix Legend’s "The most dazzling national style", and the aunts’ square dance also jumped on the stage, and martial arts and guqin performance were combined into a creative program; The folk song "Little Town Girl" sung by Zhang Ye is combined with Tao Zhe’s R&B pop songs. Pop singer Yu Quan and Peking Opera artist Yu Kuizhi also performed "Three Stores" and "Running" against each other … In a word, besides the excitement, the acrobatics program in the Spring Festival Evening wanted to give the audience something new!

　

Chopsticks Brothers and Phoenix Legend are at the rehearsal scene. Apart from singing each other’s songs, the four of them have to mix together to finish the song.

"The most dazzling national style" and "Little Apple" are two simple and catchy divine songs, but it is really not that simple to mix and sing together according to the director’s method in the Spring Festival Evening.During the rehearsal of the Spring Festival Gala, the original singers of the two songs were stupid and couldn’t tell what they were singing.

This year, Havin, the general director who is good at mashups and creative programs, came up with a PK program that allowed Chopsticks Brothers and Phoenix Legend to sing each other’s famous songs. This idea was extended into a series of wonderful mashups. The director asked a group of singers to exchange singing methods. Bel canto, pop, folk songs and Peking Opera were lively, but it was really unknown what effect they would have when they performed live.

In the rehearsal stage, Kelly Chen, a Hong Kong singer, quit because she couldn’t adapt to the singing style. Originally, the director arranged for her and Liao Changyong to exchange singing "It’s better to dance" and "I’m like a snowflake in the sky" with bel canto and pop. Kelly Chen tried more than 20 methods, but she felt very bad about herself.

In fact, this program is far more complicated than the director can imagine. For example, at the rehearsal scene, Chopsticks Brothers and Phoenix Legend, in addition to exchanging and singing each other’s songs, the four of them have to mix together and sing the song together. The catchy melodies of these two square dance songs have some similarities. By arranging and mixing them together, they almost become a complete song. At this time, the singers are required to cross the lyrics of the two songs and sing with each other, and they sing until Wang Terry, the lead singer of Chopsticks Brothers, was once stunned and didn’t know which sentence to sing next.

Looking at this scene, the audience under the stage all burst into laughter. However, if you look down again, when Yu Kuizhi, a master of Peking Opera, sings Running by Yu Quan, and Zhang and Tao Zhe exchange singing "Little Town Girl" and "All the Best", you will know that the chopsticks brothers finally got mixed up, which is nothing at all.

Don’t get me wrong, these two songs are not a mix-and-match. They are both solo songs. The reason for juxtaposing them is that they are both original works in the CCTV variety show "China’s Good Songs". Moreover, the two songs stood out in the newly added "audience evaluation" of the director group this year’s Spring Festival Evening and were gloriously selected for the Spring Festival Evening. Unfortunately, the originality of the two songs missed the stage.

Liu Huan introduced that his first reaction after receiving the performance invitation was to struggle. "The first reaction when I heard this news was: it’s not right, it should be sung by the students themselves. Even if I need to show up, I can sing with the students. I immediately communicated with Ha Dao by telephone, but in the end they insisted on my solo, accompanied by two international performers. To be honest, I struggled for a whole day before agreeing. "

As for why Slow Once upon a time was favored, Liu Huan thought, "Perhaps the main reason is this little poem by Mr. Mu Xin, which is very quiet, simple and picturesque. Now the pace of work and life is very fast, and people are impetuous. This song can hit people’s hearts at once and examine their own steps. "

Jason Wu, Zhang zhen and 48 students from Tagou Martial Arts School jointly performed the creative martial arts program "Picturesque Jiangshan", which was praised in the rehearsal. This program is full of strong "Chinese style". Jason Wu needs to walk plum blossom piles on a tower that is four or five meters high and made of dozens of mahogany chairs. In the audience’s view, Jason Wu has been swaying on the plum blossom pile, which is very thrilling.

Zhang zhen’s performance began with a piano.

In the past Spring Festival Gala, many kung fu stars, such as Jackie Chan and Chiu Man-Cheuk, performed on the stage, while Zhang zhen and Wu Jingdu attended the Spring Festival Gala for the first time. Their programs are different from the past in that they combine different styles of martial arts programs and integrate various traditional cultural spirits. Among them, Jason Wu, a kung fu star who made her first appearance in the Spring Festival Evening, mainly showed tough martial arts movements, while Zhang zhen’s performance started with dancing the piano. These two people used martial arts movements to show the calligraphy and painting of the piano and chess in the traditional culture of China, which was very aesthetic.
