Advantages:
First, the power is sufficient, and the common cars on the road can last 95% of the time, but pay attention to safe driving.
Second, save money. Even if there is no charging station installed at home, public charging is also very cost-effective. It can be charged once every three days in the city for more than 40 minutes at a time. According to the calculation of the fuel truck, it costs about three or four cents a kilometer.

Let me mention a few shortcomings.
1. There is too little storage space. I don’t even have a place to put my sunglasses. It is the car with the least storage space I have ever seen in the car. The savings entrance under the central control is very narrow. Can’t reach in.
2. The remote control key is not very sensitive.
3. The video recognizes the speed limit sound prompt and cannot be turned off. In the city, the car often warns. Very annoying.
4. The biggest drawback is that the extended range type has poor energy efficiency, and the new technology can be assured that it is hybrid.
The cup holder cover, after opening, is erected there, and there is no way to hide it. This is definitely a huge failure of this cockpit, too anti-human.

5. It feels that the speed increase is very brisk, the chassis is solid, and there is basically no noise or vibration when the engine is started, so it is very quiet. Let alone the Huawei car, it is a matter of people eating, can it be worse? The most annoying thing is to add 8,000 yuan to the charging pile.
6 riding experience: human-machine interaction, mute, handling, interior, seat comfort (0 gravity is really comfortable) Good, it can be seen that this car is attentive. If the in-depth experience is good, the home (parameters, pictures) are estimated to be off, Huawei Come on!

My friend adds two advantages:
1 The internal and external circulation of the air conditioner will automatically switch as it enters and exits the tunnel.
2 The wireless charging panel has a vent, so the phone will not overheat.
Added two disadvantages:
1. Voice control doesn’t work when it works.
The wind direction of the air conditioner can only be controlled on the large screen.
After driving for 500 kilometers, the car is not bad, but the delivery and service center is too poor, just like buying an agricultural tricycle! Many sales staff ask three questions without knowing! It has been half a month since I picked up the car, and the sales staff don’t know how to get the charging pile for me, it’s still my own!

　　　　　　　 On March 10, Li Yuchun’s 26th birthday, Long Danni, the president of Tianyu Media, specially sent a massage chair to express her wishes. Li Yuchun, who was busy with work, had problems with his cervical spine, so he was naturally very happy to receive this generous gift, so he sat up and "enjoyed". Of course, the birthday cannot be without cakes, and the appearance of five green cakes with five letters of "WhyMe" written on them also made Li Yuchun overjoyed. After blowing the candles, the five cakes were immediately divided up by many enthusiastic fans at the scene.

Nanjing started singing, wearing skirts and playing rock, and Li Yuchun became a "director" for the first time.

　　　　　　　 At the press conference, Li Yuchun, who was wearing a small gray suit, continued his handsome and capable style. However, in the exposed concert posters, Li Yuchun, who was barefoot in a white dress and black dress, was a bit sexy. Li Yuchun was very generous about trying the skirt style again, "I don’t think it’s necessary to cover up wearing a skirt now. This style was actually discovered inadvertently, but it suits me very well." In the previous concerts, the dance part accounted for a large proportion. This time, Li Yuchun said that he would have a rock style and would invite guests accordingly.

　　Rescue:

　　■ "Hurry up and see if you can save someone’s life."

　　■ "Rescue is better than a few minutes later."

　　Send to the hospital:

　　The maximum speed of taxis is almost 100 kilometers per hour

　　■ and leading pickup trucks running red lights, speeding and going in the opposite direction

　　Return:

　　■ "Do our best in professional ethics"

　　■ The video was taken, "This is a good thing, what are you afraid of?"

　　When he encountered a car accident, the taxi driver Tang Qi’s first reaction was to "hurry up and see if he can save someone’s life." On the afternoon of May 4, on his way to Pengzhou, he saw a car accident and a woman unconscious. He carried the injured into the taxi and prepared to send them to the hospital. Because he was not familiar with the road conditions, a small truck at the scene also joined in: turning on the double flash and guiding the taxi all the way to the hospital gate. During the period, the two cars ran red lights, speeding, and at one point going retrograde. Five minutes later, the injured were sent to the hospital for treatment.

　　"We’ve done our best, brother Liu," Tang Qi said to his car companion Liu Gongyong as he left the hospital. Noticing that someone was filming the scene and thinking that it might be posted online, Liu Gongyong said: "Just send it, it’s a good thing, what are you afraid of?"

　　In a car accident on the road, the taxi driver stops to save people

　　On the afternoon of the 4th, the taxi master Tang Qi picked up the car and prepared to go to Pengzhou, "to buy a dog for Guanghan’s friend." On the way, he met another taxi master in the same community, Liu Gongyong, "He just finished work, so I called him to go with him." After buying, Tang Qi drove to Guanghan, and Liu Gongyong sat in the co-pilot.

　　"There was a bit of a traffic jam when we were about to reach Sunshine," Tang Qi recalled, and after driving slowly for a while, he noticed that there was a small car on the road ahead, the rear of the car was facing the middle of the road, and the front of the car was damaged – obviously there was a collision. "There were still people watching."

　　"Is it bad to see people?" Tang Qi said in the car video. He tried to look in the direction of the accident car a few times, and when he heard his companion in the co-pilot say, "It’s possible that the person has been fixed," Tang Qi blurted out, "Let’s go and take a look." Then, he pulled the car forward and stopped. "Hurry up and see if you can save someone’s life," Tang Qi said when he loosened the seat belt and got out of the car.

　　"The driver was a man," Tang Qi told reporters. The driver and the woman in the back were fine, except that a young woman in the passenger seat was unconscious. "Her eyes are a little white, and there is blood around her mouth." He remembered that it was not easy to open the door. Some people at the scene said to wait for 120 to come, and some people said not to move easily. "I said at the time that it is now time, and the rescue is better than a few minutes later."

　　"In the past, when I studied theory, my teacher also said what to do when I encounter this situation on the road, so I probably know a little bit." In a rush of "hurry up, hurry up", Tang Qi carried the unconscious woman to the back seat, ready to go to the hospital, and another woman with him also got into the car. In the video, Master Tang did not forget to shout to the woman "Hold on".

　　5 minutes to the hospital, two cars running red lights, speeding and going retrograde

　　"We are not familiar with that side and don’t know where the nearest hospital is," Tang Qi said, at the time he also shouted "Does anyone know where there is a hospital nearby?" "There was a pickup truck parked on the side of the road ahead, and he said he would show us the way." At 18:04, the two cars drove in double flashes, and the on-board monitoring showed that the top speed of Mr. Tang’s taxis was almost 100 kilometers per hour.

　　"I asked her friend to pinch her." As Master Tang drove, he didn’t forget to tell the back row, "and asked her friend to call her name loudly, don’t let her fall asleep." After 20 seconds, the two cars came to an intersection, and there was still half a minute before the red light, but they still rushed over. Liu Gongyong said from the side: "Don’t be afraid, just ask them to help prove it when the time comes."

　　The woman in the back row never responded, and her friend cried again. Tang Qi and Liu Gongyong were also a little anxious. At one point, Liu Gongyong shouted "pull over to the side" at the motorcycle on the road. The minivan was blocked by the big car in front, and its speed slowed down. Liu Gongyong took out his mobile phone and shouted "nearby hospital" to the mobile phone, searching for route navigation. At 18:07, the taxi followed the minivan across the double solid line, borrowed the opposite lane and passed the car. At an intersection two minutes later, the two cars turned left almost as soon as the signal light turned red. At 18:09, the taxi arrived at the Second People’s Hospital of Pengzhou City. As soon as the car stopped, Tang Qi got out of the car and picked up the unconscious woman and ran to the emergency department.

　　Five minutes later, after cleaning up the dog food that had been spilled in the back seat in a panic, Tang Qi and Liu Gongyong returned to the car and started the vehicle to leave.

　　Accident Injuries:

　　I fell asleep in the passenger seat.

　　Thank you very much, taxi driver.

　　The reporter found the injured woman in the incident, Ms. Liang. After five days in the hospital, she has gone home to recuperate. "We were returning to Guanghan from Pengzhou, and I fell asleep in the passenger seat. I don’t know what happened later." She suffered multiple bumps and a minor concussion. "I really appreciate the taxi driver," she said. Ms. Liang also said that she was not wearing a seat belt at the time of the incident, "I must wear it in the future."

　　Ms. Liang’s boyfriend, Feng Xiansheng, recalled that the speed of the car was about 60 kilometers at the time. "I forgot whether there was a person or an animal on the road, and when I was avoiding, I took a direction and hit a tree on the side of the road." After waiting for the traffic police to deal with the accident, he rushed to the hospital. "The two masters have already left." For their kindness, "I am very touched and very grateful." Mr. Feng also said that he would cooperate with the handling of vehicle violations in the incident. "In this case, there will be more good deeds like this in the future."

　　"They are all good people," said Ms. Zhang, Ms. Liang’s companion that day. The pickup truck that led the way didn’t even give them contact information, she said. "They should have left when they got to the hospital."

　　Taxi driver:

　　"Doing a favor is also a good thing"

　　"We have done our best."

　　Tang Qi is the brother of Chengdu Chengfeng Taxi Company and has been driving taxis for nearly two years now; Liu Gongyong is from Chengdu Zhonghe Taxi Co., Ltd.

　　Tang Qi recalled that he had encountered a car accident on the road near the botanical garden, and he also sent people to the nearby hospital for free. "If you hurt someone, you have to do it first," he said.

　　Tang Qi felt that even though he had something to do at the time of the incident, others were "a matter of life", and his own business was nothing.

　　On the evening of the 4th, when he left the hospital, Tang Qi noticed that the left shoulder of his clothes was stained with blood. In the video, he and Liu Gongyong chatted easily.

　　"It’s nothing, it’s a good thing to do a favor." Liu Gongyong said.

　　"We’ve done our best, Ka, Brother Liu." Tang Qi also answered.

　　Someone at the scene took a video of Tang Qi and Liu Gongyong rescuing the injured and sent it to Douyin. The reporter noticed that the video had more than 600 likes. Tang Qi and Liu Gongyong also noticed that someone was filming, thinking that it might be posted online. In the chat on the return journey, Liu Gongyong said: "This is a good thing, what are you afraid of?"

　　Chengdu Business Daily-Red Star News reporter Peng Liang, the picture shows a screenshot of the video

　　China News Agency, Beijing, October 26th: Under the same starry sky, how can the East and the West carry out exchanges and dialogues?

　　- Interview with Li Liang, a researcher at the Institute of Natural Science History of the Chinese Academy of Sciences

　　Authors, Xu Jing, Du Yan

　　From ancient times to the present, the mysterious and magnificent vast starry sky has attracted the attention of different human civilizations on earth. "Chasing dreams and galaxies" is not only the romantic feelings of ordinary people, but also the pursuit of people’s careers for thousands of years. "The calendar is like the sun, moon and stars, and the time of the people is honored". People’s observation activities of the starry sky are closely related to production and life, resulting in a number of great inventions, which promote the development of science and technology.

　　Li Liang, a researcher at the Institute of Natural Science History of the Chinese Academy of Sciences, recently accepted an exclusive interview with China News Agency’s "East-West Question", tracing how human beings go from looking up at the starry sky to space step by step, telling how the East and the West communicate and dialogue around the same starry sky, explaining the role of "looking up at the starry sky" in promoting scientific progress and the development of civilization for thousands of years, and why human beings will continue their journey to the sea of stars to explore the boundless universe.

　　A summary of the interview is as follows:

　　China News Agency reporter: Why do humans observe the starry sky? When did astronomical records begin?

　　Li Liang:The history of humans looking up at the starry sky is very early, dating back thousands or even tens of thousands of years. Astronomical observations can be said to have originated from some of the most basic human questions, such as "who are we" and "where do we come from".

　　Archaeological evidence suggests that ancient Chinese astronomical observation activities date back at least to the Neolithic period. In the 1970s, a batch of Neolithic painted pottery with patterns of the sun, moon and stars was unearthed in Dahe Village, Zhengzhou, Henan Province, which was determined to be about 4,000 to 6,000 years ago. The discovery of the site of the Tao Temple Observatory in Shanxi Province confirms that there was an official observatory in China at least 4,000 years ago. It is currently one of the earliest observatories in the world discovered by archaeology.

　　From the existing archaeological and historical data, it can be seen that since about the 8th century BC, humans have had a relatively systematic celestial record.

　　The magnificent starry sky has always attracted the attention of different human civilizations on earth, but only ancient Babylon, ancient China, and European and Arab civilizations after the Middle Ages have left a rich legacy of astronomical records. Especially after the decline of ancient Babylon, between 50 BC and 800 AD, China became almost the only country that has been diligent in observing and recording celestial phenomena for a long time. Most of the surviving celestial records from this period also came from China.

　　Astronomy has many applications and is a very useful science. From a modern perspective, the accuracy and complexity achieved by ancient astronomy far exceeded that of other ancient natural sciences.

　　China News Agency reporter: Why does the same starry sky form different constellations in the east and the west? Why is the star map called "the epitome of the world at that time"?

　　Li Liang:For thousands of years, people in different regions have looked up at the same starry sky, but have their own understanding and interpretation of the starry sky.

　　Almost every ancient civilization had its own constellation system. The modern constellation system we still use today originated in Mesopotamia 5,000 years ago. At that time, the Sumerians had learned how to use stars to distinguish time and season. Gradually, in order to facilitate memory, they connected different stars and imagined familiar patterns. This is the origin of constellations. Later, constellation observations here were further developed, spreading to the surrounding areas such as ancient Greece and ancient Egypt, and influencing the surrounding civilizations. In the 2nd century AD, the ancient Greek astronomer Ptolemy summed up 48 constellations on the basis of his predecessors. This is the basic prototype of the modern constellation system. It can be said that Western traditional constellations were produced on the basis of long-term mutual exchanges and integration of multiple civilizations, and are the crystallization of the wisdom of early agricultural and animal husbandry civilizations and maritime civilizations.

　　Among the four ancient civilizations, only the Chinese civilization has continued to this day. Ancient China had its own theoretical system for dividing and naming the sky, and the constellations were usually called "star officials". The star official system took shape at the latest in the Warring States period, which was composed of the North Star and the Big Dipper, as well as the twenty-eight constellations in the Yellow Equatorial Belt. During the Three Kingdoms period, Chen Zhuo further determined the star official system of 283 star officials and 1,464 stars, which became the standard for the star official system in ancient China in the future. In the late Ming and early Qing Dynasties, people added some constellations translated from the West, and eventually formed about 300 star officials.

　　Unlike traditional Western constellations, which are mainly based on myths and legends, the ancient Chinese star official system can be said to be a reflection of society and culture in the sky, with unique cultural connotations. When Zhang Heng described ancient star officials in the Eastern Han Dynasty, he believed: "In the wild elephants, in the court elephants, in officials, in people and things, so it is ready." Therefore, most of China’s star names are named after artifacts, official names, and personnel, and the sky has become a microcosm of all aspects of the ancient world, social systems, and humanistic customs.

　　In order to use and spread constellations, the ancients drew them on different materials, gradually forming the later star map. Star maps are not only a way for people to understand and record the starry sky, but also an important tool for studying and learning astronomy. They contain the infinite wisdom and imagination of human beings and are a microcosm of human exploration of the universe.

　　Star maps were also known as astronomical maps in ancient China. There were many types of star maps in ancient China, which were exquisitely and meticulously drawn. They were an important achievement of scientific civilization and were rare in world history.

　　China News Agency: As an important part of science, has Chinese and foreign astronomy exchanged ideas and learned from each other in the process of development?

　　Li Liang:Astronomy has been a very important subject since ancient times. Among the four major sciences of heaven, arithmetic, agriculture and medicine in ancient China, astronomy was responsible for the important task of "chronicling the sun, moon and stars, and honoring the time of the people", which was closely related to production and life.

　　The astronomical calendar occupied a pivotal position in the political system of ancient China, and was even enshrined as an official "orthodox" school for a long time. Therefore, official institutions dedicated to observing celestial phenomena and compiling calendars emerged. This way of operation played a positive role in promoting the development of Chinese astronomy, making China a country where astronomical observation activities have never been interrupted among many ancient civilizations, thus leaving a rich astronomical heritage.

　　In his History of Science and Technology in China, Joseph Needham, a British historian of science, quoted Sutton and other historians of science: "From the Middle Ages until the end of the 14th century, there was no star map other than China."

　　The ancient Chinese star map spread to Japan and the Korean Peninsula, forming a unique astrological system shared by the entire East Asia region. It was also one of the important links for the dissemination of ancient science and culture. In addition, the Xuanming Calendar of the Tang Dynasty was used in Japan for 823 years, making it one of the longest-lived calendars in history. The official calendar of the Korean Sejong period (1418-1450), the "Seven Political Calculations", was compiled on the basis of the "Giving Time Calendar" of the Yuan Dynasty and the "Datong Calendar" of the Ming Dynasty.

　　It can be said that under the historical and social background of "books and texts", ancient China developed an "Eastern astronomy system" that was different from that of the West, and formed a strong cultural identity in East Asia and other regions. At the same time, the astronomical exchanges and exchanges among Eastern civilizations further promoted the formation and development of Eastern astronomy traditions.

　　Civilizations are colorful because of exchanges, and civilizations are enriched because of mutual learning. In the course of the development of astronomy, China has its own continuous export and special contribution, and has always been a broad-minded and inclusive of all kinds of excellent foreign science and culture. China has also introduced astronomy knowledge from outside the region many times in history, three of which are relatively large. Liang Qichao pointed out in "The Academic History of China in the Near Three Hundred Years": "Arithmetic is very developed in China in ancient times, but it has been improved every time under the influence of foreign countries. The first is the Brahman method in the Tang Dynasty, the second is the Huihui method in the Yuan Dynasty, and the third is the Western method passed down by the Jesuits in the Ming and Qing Dynasties."

　　China News Agency reporter: What role does ancient Chinese astronomical records play today? What impact does the development of astronomy have on the development of human society?

　　Li Liang:Ancient China had made brilliant achievements in astronomical observation and accumulated a large amount of astronomical data. Needham once commented: "The Chinese astronomical records show that the Chinese were the most persistent and accurate astronomical observers in the world before the Arabs." "Modern astronomers have turned to these Chinese astronomical records on many occasions to obtain valuable results."

　　Among the objects of modern astronomy research, many are about the evolution of celestial bodies and the universe, and the time range involved is extremely long. The precious historical materials we have accumulated are of great value. For example, there are thousands of records of solar and lunar eclipses in ancient China, which are very valuable for studying the changes in the speed of the earth’s rotation. For example, ancient Chinese records of comets, novae and supernovae, as well as sunspots, played an irreplaceable role. In the 1950s, Xi Zezong, one of the pioneers of the history of Chinese science, published the "New Table of Ancient Novae", which took full advantage of the great superiority of ancient China in complete, continuous and accurate astronomical observation data, and recorded the record of nova and supernova explosions in Chinese history, which won a reputation for the history of Chinese astronomy, the history of science and even the Chinese people.

　　No matter in ancient times or modern times, astronomy is the "vanguard" of scientific development. The countless questions that humans look up at the starry sky have not only promoted the development of astronomy, but also promoted the development of science and technology and civilization.

　　In recent years, a number of new achievements have emerged in Chinese astronomy: the "Guo Shoujing Telescope" has helped reveal more mysteries about the Milky Way, and the "China Sky Eye" has played an important role in neutral hydrogen universe research, pulsar search and physics research. Currently, the China Sky Survey Space Telescope, the "Taiji Project", and the Square Kilometer Array Radio Telescope are advancing.

　　Once upon a time, "Yi invited the medicine of immortality to the Queen Mother of the West, and Huo’e stole it to fly to the moon." Today, the moon has become an important exploration target in China’s aerospace field, with a very romantic name – "Chang’e Project"; once, Qu Yuan used a series of questions in "Tianwen" to ask and think about the origin of the entire universe. Now, the "Tianwen 1" probe and the "Zhurong" rover are providing important scientific basis for in-depth understanding of Mars; once, "Kuafu exceeded his strength and wanted to chase the sun." Now, China’s comprehensive solar exploration satellite "Kuafu 1" has been launched into space, starting a journey to explore the sun.

　　The above results demonstrate that some of the major developments China has made in the fields of astronomy and aerospace have reached the international advanced or leading level.

　　There are still many unsolved mysteries in the universe waiting to be explored. In distant places, there are pioneers of human civilization who represent the curiosity of human civilization and move forward all the way. In the future, China and other countries in the world will face the same sea of stars and trace the origin of mankind and the universe through the joint efforts of generations. (End)

　　In fact, Z-tourists who are fond of wild interests are not only keen to camp in the suburbs of Shan Ye, such as Wangzi Mountain, Siming Mountain and Wumeng Prairie, but also have fun challenging online celebrity’s cross-country punching place to become a Buddha slope.

　　In addition, some car owners drove 10,000 kilometers across Tibet and reached the Everest Base Camp at an altitude of 5,200 meters. Even 12,000 kilometers westward through the Gobi desert in the northwest, and enjoying the magnificent mountains and rivers in Altay region and Jiangbulake, Xinjiang, constantly confirmed the solid reliability of Krypton 001.

　　High-performance and efficient power control and intelligent electric four-wheel drive can easily cope with rough road conditions.

　　The 400kW permanent magnet Gemini electric drive system carried by Krypton 001 has a peak torque of 768 N m.. The advantages of quick response and abundant performance can ensure that Krypton 001 has more sufficient power to drive in light off-road conditions such as potholes and mud. Help drivers and drivers to explore Shan Ye with their families and find out more about life.

　　At the same time, Krypton 001 intelligent electric four-wheel drive system can optimize driving performance in real time in rough road conditions and accurately distribute power in milliseconds. Electric four-wheel drive intelligent driving torque distribution system and torque vector distribution braking system (DWTB) can instantly provide stronger driving force for the wheel end with higher friction coefficient according to the different friction coefficients of the front and rear wheels. When the dTCS intelligent acceleration slip regulation detects the wheel-end slip, it can also distribute the wheel-end torque instantly to increase the grip of the driving wheel at a processing speed 10 times faster than that of the mainstream TCS traction control system, thus helping the vehicle to pass efficiently.

　　In case of steep gravel slope, the special calibration of Krypton 001 cross-country mode for PedalMap and TCS traction control system will effectively curb the risk of slipping, and pulley can also reduce the tire slip rate and improve the climbing ability of the vehicle.

　　In the driver’s seat, the off-road mode interface dedicated to the instrument panel will display data such as body pitch angle and roll angle. Combined with the chassis "perspective" technology, the surrounding environment and car bottom picture of Krypton 001 can be presented in a 15.4-inch central control suspension screen from a 3D overlooking perspective. A more detailed and clear road picture can reduce the risk of rubbing the chassis and let the driver intuitively grasp the current wheel position and road conditions. With the help of the minimum turning radius of 5.9m, the best travel path can be easily selected.

　　The high-performance chassis suspension system has the high passability of SUV models.

　　In order to let users fully enjoy the fun of Shan Ye, the fully automatic air suspension system adopted by Krypton 001 can make the chassis ground clearance reach 200mm, making it have the high passability of SUV models, and the wading depth far exceeds the national standard requirement of 450 mm. Combined with approach angle 15.7 and departure angle 21.5, and the blessing of surging power, Extreme Krypton 001 can easily conquer 70% of the extreme slope ramp, showing the driving strength in all road conditions without losing SUV.

　　With the "best partner" CCD electromagnetic vibration reduction system, the suspension damping can be adjusted intelligently, and the high-performance air suspension system of Krypton 001 is also rigid and flexible, allowing drivers to perfectly control the body movement while maintaining high comfort.

　　In addition, the tough body brought by the torsional stiffness of 40,000 N m/deg improves the anti-deformation ability of the Krypton 001 when it passes through rough road conditions, which provides a solid guarantee for the reliability and safety of the vehicle. The suspension made of all-aluminum alloy and the axle load ratio of 50:50, which makes the weight of the front and rear car bodies balanced, provide a stronger grip for the extreme krypton 001 four-wheel, so that driving stability and comfort can be taken into account.

　　In terms of the safety that users attach the most importance to, the collision protection design of Krypton 001 follows the global five-star safety standards, regardless of the cockpit or battery compartment, and focuses on the protection of the weak areas at the bottom and side of the battery pack.

　　In view of the possible collision risk between the chassis and the sudden obstacles, Krypton pioneered the safety protection technology of high-voltage battery pack bottom collision. Extreme krypton 001 can make the bottom of the battery pack achieve better safety protection than the industry standard in two States: 24km/h inclined by 10% impact and 50km/h overlapped with the bottom of the battery pack by 30mm high-speed impact.

　　Extreme Krypton has been committed to breaking through the border and creating the ultimate travel experience that exceeds users’ expectations. Extreme Krypton 001, which has continuously evolved with systematic thinking, has continuously refreshed the fastest lap times on the track, and at the same time, more hidden skills have been continuously excavated. Its ability to control the light off-road environment can fully release the travel radius of users, and both cities and Yuan Ye can have more fun. (Photo courtesy of Krypton car)

　　WeChat friends circle screenshot

　　At about 13: 00 on December 2, Chen Xingjia, secretary of online celebrity County Committee of Hubei Province, publicly posted in his WeChat circle of friends, "Dear folks, I am about to leave my beloved Badong. Here, I would like to thank everyone and say goodbye through the public number of my good friend Yinuo. "

　　Previously, Chen Xingjia, the current secretary of Badong County Party Committee, born in January 1971, was designated as the "candidate for state-level leading cadres" in September 2016.

　　Chen Xingjia said in the above, "I sincerely thank all media friends for their attention and support to Badong over the years. I have completed the mission of Badong spokesperson, so I personally will not be interviewed by any media in the near future. Please stop paying attention to me personally, and please continue to pay attention to supporting Badong — — Although it is remote and temporarily poor, it is infinitely beautiful and full of hope in Badong. "

　　At the same time, Chen Xingjia attached his "parting speech".

　　He wrote, "Thanks to my colleagues and your support, several major events that the county party committee has decided to do every year in recent years have won everyone’s support. I hope that when you remember me in the future, you will understand and forget my strictness and harshness. I will no longer be your leader, but I will still be your micro-friend, your pen pal, your ball friend and your donkey friend. "

　　He also thanked many netizens. "Thank you for your enthusiastic encouragement, supervision and criticism. In fact, I have been with you all these years. I have an ID in the forum, and my name is five words (don’t guess, the administrator doesn’t know it’s me), and occasionally I have spoken and participated in the discussion. "

　　Chen Xingjia also said, "I am most satisfied with the work I have done in Badong ‘ Clean and self-reliant ’ Badong spirit, and lead everyone to practice together. I dare not say that I am worthy of my life, but I dare say that I am worthy of my heart, dare to say that I am a county party secretary who does not collect money, and dare to say that I have tried my best. "

　　Attachment: The full text of Chen Xingjia’s Goodbye, My Badong.

　　I am about to leave Badong, and I have too much to give up. In front of the window is the outline of the distant mountain in Xirukou under the setting sun, which is undulating like waves, just like my mood at the moment. More than five years seems to have passed quickly, and there are many things to say, and I don’t know where to start.

　　Before I came to Badong, my life and Badong only crossed twice. First, before I was 11 years old as a child, I grew up in Xiangxiawan Village, Gao Qiao, Xingshan County, which is only a dozen miles away from Baiwan Village on the border of Badong County. I know that menstruation was married in a remote village in Badong County. Second, I took a boat from Yichang to Chongqing ten years ago. I once passed through Badong in the misty rain. My peers introduced that Wuxiakou next to Badong County is the pattern behind five yuan.

　　On October 9, 2011, I received a notice from the Organization Department of the Provincial Party Committee to work in Badong. The word "Badong" is distant and vague, so I can only learn about my new home through the Internet. I still remember the deep shock after typing "Badong" in Baidu at first. Behind the long history and beautiful scenery, the names Deng Yujiao and Ran Jianxin firmly link the word "Badong" in the negative information of the mass network, which is mixed with resentment and hostility.

　　It took me a week to search Badong comprehensively and get to know Badong. My notebook was full of ten pages, and my heart had already arrived before the people arrived. On October 15th, 2011, I left Yidu and set foot on the land of Badong. I come with a heavy responsibility, with deep concern and full of enthusiasm.

　　In November 2011, I boarded the Damian Mountain for the first time. On the sedan chair rock surrounded by red leaves, I overlooked the Yangtze River flowing from the horizon through Wuxia, and I was inexplicably moved. I remembered Tagore’s sentence, "This is the farthest journey, and I came to the place closest to you … …” I think I found my own door here.

　　That night, I wrote my first poem after coming to Badong:

　　Finally, I came to this river,

　　Through the setting sun, through the dense forest,

　　I saw you,

　　At the end of the red leaves, you stand alone,

　　Is this the distant and clear you in your dream?

　　How many years have you been waiting here silently?

　　Honey, I’m coming!

　　I found you, in this life!

　　I want to tell my past life,/we have met in this life;

　　I want to tell my next life, the next life,

　　Because of love, I am willing to be a happy stone … …

　　These years have passed like this. At this moment, I feel that I am a happy stone, and I fell here in the best time of my life. Wake up in the mist and glow in the morning, walk in the mountains and waters during the day, walk in the shadow of the ship’s flute and light in the evening, and fall asleep with the sound of waves at night. Looking back on every day in Badong, it is happiness.

　　Using the simplest words to express the mood at this time is "thank you".

　　Thanks to the 500,000 folks in Badong, thank you for your acceptance, and let me feel back to my hometown at the first time. Although my hundreds of thousands of poor relatives in Badong no longer serve you directly, I will still care about you and try my best to do something for you.

　　Thanks to my colleagues and your support, several major events that the county party Committee has decided to do every year in recent years have won everyone’s support. I hope that when you remember me in the future, you will understand and forget my strictness and harshness. I will no longer be your leader, but I will still be your micro-friend, your pen pal, your ball friend and your donkey friend.

　　Thanks to my old kiss menstruation, my mother’s elder sister who was most concerned and distressed before her death. And my three cousins, you work and live silently in remote villages. Over the years, you have never looked for me, and you have not let others know that you are the closest relatives of the county party secretary. Even if menstruation was seriously ill and came to the county hospital for hospitalization, you did not let me know.

　　Thank you for your enthusiastic encouragement, supervision and criticism. In fact, I have been with you all these years. I have an ID in the forum, and my name is five words (don’t guess, the administrator doesn’t know it’s me), and occasionally I have spoken and participated in the discussion … … I would also like to thank the stones, bugs and little birds in particular. Your deep love and responsibility have always insisted on speaking out from a critical perspective, which is very helpful to my work.

　　Finally, I would like to thank Wang Ming, Pu Cunxin, Di Sen, Deng Fei, Yuan Hui, Chen Jingxiao, Li Jie, Peng Fei, An Yu, Zhou Jian, Rose Tong &hellip for their silent dedication, support and service to rural public welfare in Badong. … And all the long-term or short-term, famous and unknown supporters. You don’t seek fame or gain, you are full of compassion and enthusiasm for the disadvantaged, and your spirit and feelings warm the still barren land here. Five years in Badong, interacting with you, also let me always face my true self from the grassroots, and deeply feel that serving the grassroots is the happiness I have been pursuing.

　　What I am most satisfied with in my work in Badong is that I have condensed the spirit of "clean and self-improvement" with you and led you to practice it together. I dare not say that I am worthy of my life, but I dare say that I am worthy of my heart, dare to say that I am a county party secretary who does not accept money, and dare to say that I have tried my best.

　　What I regret most is that in the past five years, Badong’s industrial development has been struggling. In recent years, the eco-cultural tourism industry, which we have exerted the greatest efforts, has not really taken off until this year. Several major projects launched at the end of last year and this year, such as photovoltaic poverty alleviation in State Grid, high-speed rail town and Yingcai Waterfront in the Yangtze River, let us see the dawn, but there will be many difficulties in the implementation process. My successor colleagues, the task of leading the villagers in the county out of poverty and towards a well-off society is still very heavy.

　　Yan Ping is diligent and honest, and Guo Ling has feelings and responsibility. I believe my successor colleagues will do better than me. I believe that in the future, Badong will have beautiful political ecology, beautiful social ecology and beautiful natural ecology. It is the cleanest and most beautiful town near the Yangtze River, a place where foreigners don’t want to go when they come, and a place where people living here feel happy!

　　I left clearly, just as I came clearly; I waved my sleeve without taking away a cloud. Goodbye, my Badong! There are no traces of wings in the sky, but I have flown. Over the years, the mountains are long and the waters are wide. You are in my heart and in my dream.

Geely, Volvo and Lectra all rely on CMA architecture. Does buying a Geely really mean buying Volvo? I believe this is many people’s doubts about the products of these three brands.

So, what is the main reason for doubt? First of all, Geely, Volvo and Link all belong to Geely Group. Furthermore, they all adopt CMA architecture. Finally, the products based on this platform are very similar in driving characteristics, which is the main reason why consumers have questions.

# What is architecture?

Before the concept of platform architecture was born, every product of major car companies was developed, manufactured and verified bit by bit from scratch, and circulated again and again, creating the final production model. I believe we have all heard that the birth of a new car at that time took at least 2-3 years of research and development cycle, which was very energy-consuming, time-consuming and capital-consuming for car companies. Therefore, there was the concept of building a car on a platform.

The first model to apply the platform concept is the Volkswagen Beetle. Although this model has been discontinued at present, it is its hot sale that makes the prototype of the platform car concept take shape.

The birth of the platform will bring very good cost reduction effects to enterprises, including reducing R&D costs and shortening R&D cycle; Reduce the cost of parts and improve the sharing of parts and components; Reduce the supply chain management system and reduce the number of parts.

Not only that, the major platforms that have emerged in recent two years are speculating on one advantage, that is, the platform can be compatible with the production and research and development of products from A0-C level, which is very important. In other words, car companies only need to spend a lot of energy and time in the early stage to do a good job in the compatibility and safety performance of the platform, and then they can launch products such as A0-class cars, medium-sized cars or medium-sized SUVs on this platform, with low cost, high efficiency and "fast delivery".

# Is it really good to use the platform?

At present, major car companies are speculating on the advantages and strength of their own platforms and architectures. But don’t forget that the original intention of the concept of platform and architecture is actually to help enterprises save R&D costs, so this is why many products under the same platform have similar personalities.

Everyone is most familiar with the Volkswagen MQB platform and the Toyota TNGA architecture. Volkswagen has adopted this platform from Tiguan and Passat to Golf and Sagitar. The earliest PQ25 and PQ34 are all like this. It is precisely because of the platform architecture that we see that many Volkswagen products are obviously only front-drive cars, but the rear row has a very large bulge and the space utilization is extremely poor. Moreover, for example, the early low-profile models such as Golf, Sagitar and Jetta are criticized for their knob seat adjustment methods. Toyota’s products based on TNGA architecture have more compact and sporty chassis, without the soft and comfortable models of the year.

# Geely Group CMA Modular Architecture System

Let’s talk about China automobile brands again. With the increasing sales of automobile products and the demand for new products, the R&D cycle of products under the previous R&D system of enterprises is obviously too long, and it is very likely that the products will not keep up with the current mainstream problems of automobiles after they come out.

At this time, China enterprises represented by Geely came forward, and the CMA platform jointly developed by Geely and Volvo was launched. This is an infrastructure for mid-level cars, which can cover A-B model products.

Systematically speaking, CMA platform has considered the future production and manufacturing at the beginning of design, and will consider the universality of some parts in advance, such as our common window controller, in-car function buttons, engine foot mounting holes and so on.

Another great advantage is that the platform wheelbase and wheel track can be lengthened or shortened according to the positioning of R&D products, and it can adapt to more different types and levels of products on this platform. For example, there are many types of products born from CMA platform, such as Volvo XC40, Lingke 01, Lingke 02, Lingke 03, Lingke 05, Xingyue and Xingrui.

# Buying a Geely or a Lexus is equivalent to buying a Volvo?

If you have had contact with Geely, Lectra and Volvo products, you will understand the significance. Especially in the dynamic driving part, the suspension is tight and tough, and the driver can clearly perceive the road information. Especially when coming to the mountain road, the whole chassis suspension adjustment pays attention to communication, aiming to let the driver experience the fun of control.

Similar driving experience, which is one of the advantages based on the same platform. On the other hand, under the same platform, the safety performance of vehicle collision will be more guaranteed.

Taking Volvo XC40 as an example, the 2019 model got the highest score in the five major projects of American IIHS crash test. On the other hand, Linke 01, which is built on the same platform, has also achieved excellent results in all the tests of C-IASI with the same crash test project as IIHS in China. Especially in the 25% offset crash test of most joint venture vehicles, Volvo XC40 and Link 01 both achieved G-excellent results.

Geely Xingyue, also born on CMA platform, scored only M in the C-IASI25% offset collision, but the head, neck, chest, thighs, hips, legs and feet of the dummy all got G evaluation, which showed good protection performance for the dummy.

Reminiscent of Geely Xingrui, which has just been listed recently, from the data, its wheelbase of 2800mm fully meets the medium-sized car level, but the official positioning is family car, which is commonly known as compact car. However, the performance of Geely Xingrui is completely beyond the strength of compact products of the same class. In addition to excellent body size and space performance, the whole system is equipped with a 2.0TD engine, and the top price does not exceed 150,000.

If we compare the power data of Geely Xingrui with that of Volvo S60 T4, the same 2.0T engine has a maximum horsepower of 190Ps and a maximum torque of 300N·m, but the maximum power speed and torque speed of Xingrui engine are slightly advanced in the details. In the body size part, the data of length, width and height are ahead of Volvo S60, so how would you choose between them? And this is the advantage of building a car based on the platform architecture.

Summary:

This article doesn’t use too many technical terms or data. Brother Peng just wants to tell you with some easy-to-understand examples and words that there is no difference between good and bad in the platform architecture debate. For example, the MQB platform, which is widely used in the mass civilian field, is it really that good? Not necessarily.

Then, in the CMA platform currently used by Geely and Lectra, for example, it is basically the same origin as Volvo, and the adjustment of excessive sports has obvious brand tonality. But it will also shut out potential users who have a strong demand for comfort.

In the smaller part, that is, the universality of parts, each platform has its own characteristics. The advantage is that enterprises can save the cost of parts procurement, transportation and process. However, in the event that some parts suppliers have problems, consumers will end up "backing the pot".

Back to the original answer, Brother Peng personally feels that this should be considered from two aspects. One is the quality of hardware, based on the same architecture, the commonality of many parts, and the extra points in the safety performance, which are very Volvo and CMA.

If we understand from the rest of the software, the concept, design, configuration, brand and price are different, and both Geely and Lectra have their own characteristics, which is why Geely built the Lectra brand.

Then, if someone asks Brother Peng, does buying a Geely really mean buying a Volvo? My answer is, yes. Not only that, in the configuration part, Geely products will be more abundant than Volvo models. How to choose and how to recognize is up to you.

After entering 2019, it is not difficult to find that domestic brands, which used to dominate the domestic new energy market, began to add a lot of pressure on competitors. This stems from the fact that joint venture brands and luxury brands have been "late" for a long time and started to exert their strength in the domestic energy market, and launched different levels of pure electric vehicles respectively.

However, whether it is a domestic brand with good sales volume and early entry into the market, or a joint venture brand and luxury brand that has accumulated a lot of money, it has been deeply cultivated in an autonomous driving and promoted as a highlight. Not only are manufacturers trying to publicize how advanced their self-driving function is, but even during the previous shop visit, Mr. Bang heard that many consumers kept asking salespeople about the self-driving level of their vehicles and the functions they can achieve, so it can be seen that consumers still rely on this function.

Previously, during the process of exploring BYD Song Pro EV, Mr. Bang had heard that some consumers asked the sales staff, and BYD Tang EV and DM models could upgrade the automatic driving function to realize real L2-level automatic driving. Coincidentally, Mr. Bang recently received an invitation from BYD to go to BYD Xinminheng 4S store in Daxing District to experience the three major functional upgrades of the new generation of Tang models.

Which three highlights are upgraded?How to upgrade?

BYD specially launched a free upgrade activity of "Enjoy the upgrade with wisdom, be all for you" for the new generation of Tang EV and DM models. The upgrade projects brought by this upgrade activity include active lane keeping system, 360 holographic transparent image system and karaoke function.

▲ The maintenance master checks the vehicle before using the computer to upgrade it.

In order to ensure the customer experience during the upgrade process, the above upgrades will be opened in batches. The new generation of Tang DM and EV models began to make an online reservation on December 16th (booking the upgrade time to the store on and after December 20th), and officially started to upgrade to the store on December 20th; The fuel version of the model began to make an online appointment on December 28, and officially opened to the store for upgrade on January 3 of the following year. In addition to telephone booking with authorized service stores, the booking method can also be successful by logging in to the "Difenhui+"WeChat applet, authenticating the owner and entering the booking service interface, and completing the information according to the guidelines.

▲ This major upgrade project is included in the option "(Bosch) Multimedia Video Controller", with the version number of 2.00.12.

The three functions of this upgrade are provided by the manufacturer free of charge, and the reception services are provided by authorized service stores, and only the basic working hours of authorized service stores (399 yuan) need to be paid. This is undoubtedly a major benefit for the new generation of Tang car owners; As far as BYD is concerned, it is also an important recognition that it has been pursuing technological innovation to bring about the "common and often new" evolutionary experience.

▲ The maintenance master said that the communication of some main controllers will be blocked during the upgrade process, so the corresponding fault codes will pop up on the dashboard.

What models can be upgraded?

1. A new generation of Tang EV Zhilian creation type, Zhilian creation type and Zhilian creation version.

▲ Tang EV
2. A new generation of Tang DM four-wheel drive distinguished model, Zhilian Chuangrui model, Zhilian Chuangxiang model, Zhilian Chuangling model and Zhilian Chuangshi version.

▲ Tang DM

3. A new generation of Tang fuel, Zhilian distinguished type, Zhilian honorable type and Zhilian honorable type.

▲ Tang Fuel Edition

What will the three highlights become after the upgrade?

1. 360 holographic transparent image system

Starting mode: it can be turned on by the steering wheel button.

▲ Before the upgrade, it was opaque.

On the basis of the original panoramic composite top view, according to the images collected by four super wide-angle cameras around the vehicle and the actual vehicle motion law, they are input into the image processing chip, and then processed by software to be seamlessly spliced to output panoramic images, presenting a holographic transparent bird’s-eye view of the whole vehicle. Using this system, users can easily show the obstacles on the road to drivers, and drivers can make corresponding evasive actions according to the road conditions to ensure safe driving.

▲ Display the "360 holographic transparent image" system after upgrading.

2. Active lane keeping system

Starting mode: it can be started through the vehicle options in the DiLink screen, or through the function buttons in the shift area.

The lane dividing line is identified by the MPC camera on the top of the front windshield. When the vehicle speed is ≥ 60 km/h, if the vehicle deviates from its own lane and the turn signal is not turned on, the system will first issue a warning prompt. If the driver doesn’t respond, the system will exert a torque on the steering wheel through the EPS electronic steering system to keep the vehicle in the own lane, reduce the driver’s steering burden and improve driving comfort. In this process, if the driver turns on the turn signal or turns the steering wheel at a large angle, the system defaults that the vehicle is taken over by the driver and stops intervening. When the vehicle speed is less than or equal to 55 km/h, the active lane keeping system will quit.

▲ Before the upgrade, there was only the "lane departure warning" function.

The sensitivity of this function can be set to "standard" and "intelligent". Standard: In the case of lane change, sudden acceleration and deceleration, the function will not be inhibited; Intelligence: Restrain the implementation of this function in case of lane change and sudden acceleration and deceleration. In addition, in order to reduce the interference of the system’s active exit to the driver, the lane keeping assist system cannot set the steering wheel vibration reminder function, and the instrument will beep for early warning when the system actively exits.

▲ The "lane keeping" function can be displayed after the upgrade.

When the lane keeping assist system is working, when the system monitors that the driver has not grasped the steering wheel for 15 seconds and is out of control of the vehicle, it will give a warning of getting rid of it, and the instrument will prompt a warning text reminder of "Lane keeping has been withdrawn, please take over the steering wheel"; At this time, if the driver still does not hold the steering wheel to control the vehicle, the function of lane keeping assist system will exit; The warning will also be issued when the driver continues to operate the steering wheel only slightly to control the vehicle.

The lane keeping assistant system is based on the multifunctional camera on the front windshield. If the camera detects that the visual field is dirty, the instrument will pop up a text reminder that "the environment is limited and the smart camera is not available"; If the front windshield where the camera is located is damaged, it will seriously affect the normal use of the lane keeping assist system.

3. K song function

Start-up mode: use the equipped microphone to match the channels without radio, and then open the K-song software supported by the system, including national K-song, sing bar, cool K-song, Mi Gu love singing, love singing, K-meter, K-singer, wheat singing, multi-singing, good singing, etc., to start karaoke in the car.

▲ National K Song Software

After the K-song function is upgraded, all vehicles will be able to use the K-song function, and the UI interface will be more interactive and experience-oriented, allowing users to enjoy the charm of mobile KTV.

With the end of "tradition" and the rise of "intelligence", the connotation and definition of automobile are changing. In the modern Internet era, although the depreciation rate of Xing energy vehicles is still in a "higher" trend, continuous iterative upgrading can help new energy vehicles reduce the depreciation rate. And BYD’s upgrade activities for a new generation of Tang models that have been on the market for some time are the best examples.

On the other hand, from the perspective of automatic driving, the Qin Pro series and Song Pro series of BYD Dynasty series have been equipped with L2-level automatic driving function, and the new generation of Tang, as the flagship model in the family, has realized a complete L2-level automatic driving assistance function after this upgrade, which can not only improve the sales volume, but also create a better practical experience for users.
