We have tested the new Santana before. Now I don’t know what to say about the new Jetta. Everyone is already familiar with every detail. I don’t know why, the performance test results of the new Jetta are much slower than that of the new Santana. Perhaps it is the differentiation treatment specially made by Volkswagen Group for the two products. We can only understand it this way. In addition, as an entry-level model, the new Jetta is still a little expensive, and some discounts will be more cost-effective, so we can wait.

Evaluation Editor-Hu Zhengyu:

Finally put the new Jetta to the test. The public has created such a large number of regular troops with uniformity and no personality to fight, and they are good at doing business.

● Dongfeng Nissan-Xuanyi Pure Electricity

Coping strategy: none
Duration: None

　

『2018 modelXuan yi chun Dian』

　　The comprehensive cruising range of Xuanyi Pure Electric is 338km. According to the 2019 New Deal, it can get a subsidy of 18,000 yuan. However, according to the subsidy policy in 2018, the car can get more than 80,000 subsidies, with a difference of more than 60,000 yuan. At present, Dongfeng Nissan has not launched a sales strategy about Xuanyi Pure Electric. During the visit, some 4S stores in Guangzhou and Shijiazhuang did not have existing cars, and a 4S store in Beijing stopped selling until further notice.

Full text summary：

　　The landing of the New Deal in 2019 has brought new energy vehicles into the era of low subsidies. Many people predict that new vehicles will usher in a wave of price increases. However, through our visit, we found that the prices of new energy vehicles have not changed significantly, but the preferential margins of models in some regions have shrunk to varying degrees. Although Changan Automobile, BYD, and Great Wall Motor’s Euler brand have issued insurance plans, the time span is not long; Chery Automobile raises the guide price by releasing new year models. This "price increase" method is more clever and easier for consumers to accept.

　　It has been more than a week since the New Deal was launched, and most new energy vehicle companies have not announced their new sales strategies. After all, not every company wants to pay for the subsidy. What are these car companies waiting for? It may be the competitor’s action, and the latecomers can better find the balance between sales and profits. In the cold winter of the automobile market and the transition period of new energy vehicles to marketization, price increases are no different from risks! Next, we will continue to investigate the terminal sales of some popular new energy vehicles and the implementation of official price protection measures, so stay tuned.

　　Core reading

　　By the end of September, the proportion of e-commerce express mail in China was no longer more than 90%, and the number of mail express mail with recyclable packaging exceeded 800 million. The green management of express packaging in China achieved initial results, and the express delivery industry accelerated the pace of green and low-carbon development.

　　Since March this year, the monthly business volume of China’s express delivery industry has reached 10 billion pieces, of which the growth rate of business volume in the second and third quarters has maintained double digits. While the market scale is steadily expanding, the mission of green and low-carbon development in the industry is even more arduous. At present, how effective is the green management of express packaging in China? Next, how can the express delivery industry better go green?

　　The green management of express packaging has achieved initial results.

　　Near "double 11", packages are delivered frequently in Shigatse, Tibet. In ZTO Express outlets, each store has a recycling bin, and many unpacked express boxes are neatly placed among them.

　　"At first, we would advise customers to unpack their bags on the spot and put them in the recycling bin. Later, everyone gradually got used to this way of picking up." Zuo Xiaofeng, the person in charge of Shigatse outlets in ZTO Express, said that at present, 22 terminal outlets in the region have used recycling boxes, and the recycled express boxes are basically intact, with high secondary utilization rate.

　　Identity encryption, code scanning and unpacking … … In September this year, Yunda Express first launched a recyclable smart document bag. "This file bag is not only waterproof, fireproof and dirt-proof, but also can be reused many times, without using tape, saving consumables and being more environmentally friendly." Zhou Baigen, executive vice president of Yunda Express, said that this kind of file bag has been popularized and applied in many cities across the country.

　　Thousands of express parcels have brought increasing express packaging, and recycling has become a key measure for green management of express packaging. "From the perspective of materials, express waste packaging is divided into paper and plastic. Among them, more than 90% of paper packaging wastes such as envelopes and boxes can be recycled through social recycling, network recycling and post recycling." Lin Hu, deputy director of the Market Supervision Department of the State Post Bureau, said.

　　Through the joint efforts of the whole industry, the green management of express packaging in China has achieved initial results. By the end of September, the proportion of e-commerce express mail in China was no longer over 90%, over 800 million pieces of mail express mail were recycled, 127,000 postal express outlets were equipped with standard packaging waste recycling devices, and over 600 million corrugated boxes with good recycling quality were recycled.

　　Green packaging, both recyclable and "subtraction". In May this year, the State Post Bureau organized a nationwide random inspection of package data. The data shows that the standard rate of mail express packaging exceeds 75%, especially in reduction. In terms of orders, the use of electronic waybills in the whole industry has basically achieved full coverage; In terms of packaging, the number of layers of corrugated paper in the packing box was reduced from 5 to 3, with a reduction of 40%; The width of the adhesive tape is reduced from 60mm to below 45mm, with a reduction of 25%. In the use of materials, the packaging of heavy metals and solvent residues exceeding the standard has been effectively curbed. Lin Hu introduced that by the end of September, a total of 132 enterprises had obtained 158 green product certification certificates for express packaging.

　　Green development concept accelerates the integration into the whole process of express delivery industry development.

　　Promoting the green and low-carbon development of express delivery industry as a whole, packaging green governance is only one of them. "At present, the industry’s eco-environmental protection work has shifted from green management of express packaging to ‘ Double carbon ’ Work-oriented, comprehensive green development and shift period to help high-quality development. " Lin Hu said.

　　Looking at infrastructure construction, rooftop photovoltaics are constantly emerging. Since the beginning of this year, major express delivery companies have increased investment in renewable energy and infrastructure construction, and promoted the green transformation of logistics parks while improving transit efficiency. Up to now, SF has built photovoltaic power stations in 12 logistics parks, including Yiwu, Zhejiang, Hefei, Anhui and Quanzhou, Fujian. In the first nine months of this year, the renewable energy generated more than 15 million kWh, and the emission reduction exceeded 10,000 tons of carbon dioxide equivalent. JD.COM has completed the construction of 23 distributed photovoltaic power plants in Asia No.1 Park, with a total installed capacity of 132.5 MW.

　　Looking at the investment in transportation equipment, new energy and clean energy vehicles are more popular. According to the data of "Carbon Emission of Express Industry in China", in 2022, the carbon emission of the express industry in China was 34.91 million tons, accounting for 62.7%. Promoting carbon reduction in the express delivery industry requires deep emission reduction in the transportation sector. In February this year, the State Post Bureau and other eight departments issued a notice stating that by 2025, the proportion of new energy vehicles in new and updated vehicles in pilot areas such as postal express delivery will strive to reach 80%. "At present, major brand delivery companies have widely used new energy and clean energy vehicles, and continue to promote the transformation and upgrading of transportation modes through various measures such as increasing investment scale, strengthening energy consumption monitoring and optimizing transportation routes." Lin Hu said.

　　Look at low-carbon technological innovation, and accelerate the promotion of new smart devices. Jingdong Logistics normally operates intelligent express vehicles in several cities, and SF UAV realizes real-time logistics in the same city & HELIP; … In recent years, major express delivery companies have innovated terminal delivery methods, accelerated the popularization and application of new intelligent facilities and equipment such as drones, unmanned vehicles, unmanned warehouses and intelligent letter boxes, and reduced carbon emissions while improving transportation efficiency.

　　It still takes a long time to promote the green and low-carbon development of the industry as a whole

　　"Compared with the requirements of high-quality development, the green development of express delivery still has shortcomings in terms of systematicness, synergy and effectiveness." Lin Hu said, firstly, the upstream and downstream coordination and the whole chain governance mechanism have not yet been established; secondly, the situation of joint management by the central and local governments has not yet formed; thirdly, the research on the carbon emission accounting system matching the development of the industry is still in its infancy.

　　Take the green management of express packaging as an example. At present, recyclable express packaging is entering the stage of large-scale application, but compared with the increasing express business, the use of recyclable packaging accounts for less overall. "The high cost of packaging and the difficulty in recycling at the end are the main reasons." According to the analysis of experts in the industry, taking the recyclable packing box as an example, the procurement cost is 15 to 20 times that of the same specification carton, and the average single-use cost is greatly increased compared with the ordinary carton when the operating costs such as recycling, cleaning, loss and allocation are superimposed. At the same time, some consumers have not yet established the consumption habit of using recycling express packaging, and it is common that they don’t understand and cooperate with recycling packaging, so it is difficult to form large-scale use and recycling.

　　Lin Hu said that the next step will be to promote the green and low-carbon development of the express delivery industry from three aspects: strengthening the whole process support, promoting the whole chain governance and strengthening multi-link supervision, and gradually build a new path of high-quality development with government-led, social supervision and industry self-discipline.

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.

[business card]

"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.

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.

Recently, the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of Laws in the Trial of Punitive Compensation Disputes over Food and Drugs (hereinafter referred to as the Interpretation) was released on August 21, and came into effect on August 22. This document regulates malicious high claims, continuous purchase claims and repeated claims, and all support punitive compensation claims within the scope of reasonable living and consumption needs. This is a wake-up call for the professional counterfeiters: do not let "counterfeiting" become "fake fighting".

For a long time, professional counterfeiters have played a complex and subtle role in the field of consumer rights protection. On the one hand, with their keen insight and mastery of laws and regulations, they exposed and cracked down on batches of fake and shoddy products, effectively purified the market environment and protected the legitimate rights and interests of consumers; On the other hand, driven by interests, some professional counterfeiters have gradually deviated from the track of justice, alienated "counterfeiting" into a tool for profit, and even resorted to illegal means to extort money, seriously disrupting the market order and damaging the authority and credibility of the law.

The promulgation of the new Interpretation is a powerful response to this chaos. It clearly defines the boundary of "knowing and buying fakes" in the field of food and medicine, and emphasizes that punitive damages must be within the scope of reasonable living and consumption needs, which is not only a further guarantee for consumers’ legitimate rights and interests, but also a profound norm for professional counterfeiting. It tells us that the law supports legitimate and legitimate rights protection behavior, rather than making illegal profits by taking advantage of legal loopholes.

The existence of professional counterfeiters should have been a positive force in the market supervision system and a line of defense between consumers and businesses. However, when "counterfeiting" becomes "counterfeiting", this force loses its due glory and even becomes a negative factor in the market. Malicious counterfeiters use legal loopholes to extort money in the name of "counterfeiting", which not only makes businesses miserable, but also makes the regulatory authorities exhausted, resulting in a great waste of social resources. In the long run, it will not only weaken the public’s trust in the law, but also cause more social contradictions and problems.

Therefore, we must be soberly aware that professional counterfeiting is not illegal, and their behavior also needs to be strictly bound and supervised by law. For those malicious counterfeiters who extort money in the name of counterfeiting, the law must show their swords, hell to pay. At the same time, we should also strengthen the education and guidance to consumers, improve their legal awareness and self-protection ability, so that they can rationally and legally safeguard their rights and interests.

In addition, the government and all sectors of society should work together to build a more perfect market supervision system. By strengthening the construction of laws and regulations, improving the efficiency of law enforcement, increasing punishment and other measures, a powerful deterrent to counterfeit and shoddy products has been formed. At the same time, encourage and support all sectors of society to participate in market supervision, and form a good atmosphere for the whole society to govern together. Only in this way can "counterfeiting" return to its true meaning and make the market environment clearer and healthier.
