Is BYD Han EV worth buying? I’ll tell you all the advantages and disadvantages without reservation. You can wait.

It’s my first time to drive a tram home for the New Year. BYD Han EV (parameter picture) is the top version, that is, the four-wheel drive accelerates for 3.9 seconds in 100 kilometers. First of all, one of the biggest experiences of driving it during this period is very cool, especially in our mountainous area, there are many kinds of uphill roads, including I went to Yangtian Lake and climbed steep slopes, including some sand roads.

Especially when I was going uphill, I used to drive an oil truck. When I was going uphill, I felt that I had to work hard before I went uphill. It didn’t feel this way at all. You wanted to go uphill, okay, and go. This feeling was particularly crisp and neat. This is why many friends went to drive an oil truck again after driving the tram, and they felt that this oil truck was old and boring.

The second problem that many friends will worry about is the endurance, because I ran more than 300 kilometers and 380 kilometers from Changsha and ran back to my hometown, and then I used the car in my hometown all this time. To be honest, after I just took this car, I fully charged it and then ran back to my hometown from Changsha. I was really anxious. In fact, I have been looking for this anxiety myself. Who gave me the anxiety because I usually made this piece of things myself?

In fact, I feel more anxious about the uncertainty of charging. For example, when I came back from Changsha, I took the Xuguang Expressway. I checked, basically, there are no charging piles in the service area from the Xuguang Expressway Changsha to my home. The entire high-speed service area in Hunan has the most comprehensive layout of charging piles, basically along the Beijing-Hong Kong-Macao Expressway, but there are many high-speed trucks in Beijing-Hong Kong-Macao, and the road in Hunan is narrow, so basically I won’t choose that side.

Later, I had to check, and there was a charging place not far from Hengyang Expressway. At this time, my anxiety would be relatively better. When I first started driving it, it showed that the cruising range was more than 500 kilometers, that is, it was less than 400 kilometers from Changsha to my home, so I guess if I drive a little more cautiously and have a little cotton feet, I can make do with it.

Therefore, in the first half, it should be about 130 kilometers from Changsha to Hengyang’s slope weir service area. At this time, I really drove cautiously, and there was a traffic jam for an hour at that time. In addition, the temperature was very low at that time. When I was driving, in order to take care of my child’s illness, I adjusted the temperature of the air conditioner to 28~30 degrees, which often expelled the fog. Moreover, due to the bad weather that day, I turned all the lights, including fog lights.

Plus, because it’s home for the New Year, the trunk is full of things, and things are still heavy, so it’s a fully loaded state. In this state, when I ran to the slope weir, I used 50% of the electricity. However, there are still more than 200 kilometers to my home, which I think is definitely not enough. Therefore, from this period, when I return, it is probably estimated that the endurance in this case should be about 60% off. This endurance is actually acceptable to me, because the conditions were really limited at that time. When I ran in the second half of Hengyang after charging, I was not anxious at all.

The third point is about charging anxiety, which I concluded later. The most anxiety actually comes from the uncertainty of charging. When I returned, because it was before the Chinese New Year, I didn’t know whether the charging pile should be lined up at that time, how many people should be lined up, and whether the environment of the charging pile was good, especially when it was raining, so I also thought about whether I would get soaked when charging, so these experiences of poor charging.

For finding a fast charging station, there are many experiences, charging time and queuing. These uncertain factors will cause car anxiety. I think if new energy vehicles want to develop better in charging, a big positive solution lies in charging service, which is why I can finally understand why some manufacturers, such as Tesla, want to introduce power exchange and build their own super charging piles.

Fourth, although this car, Han EV, has been on the market for such a long time, I still want to talk about the driving experience. If you want to talk about the power, we don’t have to talk about the acceleration. I want to talk about its shortcomings, especially when I drove it to Yangtian Lake this time, many of them were uphill, and they encountered sand roads and icy roads. At this time, I could obviously feel that the chassis of this car was adjusted, and

At present, BYD has made great progress in the three-electric technology and the whole car system, including the appearance, and in some technologies, it has achieved such a position that the industry is close to the head, but the chassis, as a very important part of the car, really cannot be ignored. Next, if BYD wants to go further and better, it should really make a good effort in the chassis.

In this way, this car will become more perfect. Besides, BYD’s whole driver assistance system is really backward at present, and its experience is worse than that of other new forces. Therefore, this piece still needs a good effort. Generally speaking, it has some shortcomings, but its advantages are also very obvious. It is like a young guy with many shortcomings and many advantages. The advantages and disadvantages are obvious. In fact, it has been tested deeply.

Well, that’s all. During the Chinese New Year, Brother Miao drove a long distance to visit relatives, all of them drove it, and I really had some car experience. I also hope that my experience can give you some reference. Of course, if you also watch the hero EV, I suggest you wait a little longer, because the next generation will be more perfect. If you are considering buying a car, I will give it to a leader in the tram industry like BYD, and if I experience its products.

Be sure to make a decision according to the items I mentioned and your own actual situation. If you can’t meet these conditions, I suggest that you can still give priority to the oil car. If you have to buy a tram, unless it is the second car at home, it will be a little easier to use, so that you won’t be embarrassed when you encounter special circumstances.

The engineer incarnates as a "fruit hunter": the person who wants to be the most knowledgeable about fruits in China.

  Sabah fruit, like a ball of wool, has rows of compact "match sticks" on the peel, which feels the same as touching a freshly shaved head; The banana industry’s "family bucket" of horn bananas, one top ten, guarantees that you can’t eat the second after eating one; The bullet-seed melon that will pop out its seeds when it matures, the sea bottom coconut that is vividly called "woman’s ass fruit", and the shampoo fruit that is said to have a faint violet fragrance even after eating it … … These fruits that you have never heard of once appeared on Yang Xiaoyang’s target list, and now they have become his "trophies". Their photos lie quietly in his computer, and only the owner of the photos, Yang Xiaoyang, knows how much bitterness was behind the "intimate encounter".

  Yang Xiaoyang is 30 years old, and the title of "Fruit Hunter" has been with him for a long time. He has eaten more than 600 kinds of fruits, including more than 100 kinds of durian alone. Since he decided to be a "fruit hunter" in 2013, he has almost traveled to hundreds of rainforests in Singapore, Malaysia and other places, photographed hundreds of thousands of plants and witnessed more than 30,000 kinds of plants with his own eyes, accounting for almost 1/10 of the world. Although he seems to be a "fruit encyclopedia" now, in fact, his major in college is far from fruit — — Precision manufacturing.

  Being a happy person who "dares to do what he likes" in the netizen’s mouth, Yang Xiaoyang said that the experience of looking for fruit is far from as easy as everyone imagined, and he is not a "rich second generation" who "eats 500,000 fruits at his own expense every year". On top of curiosity, his ultimate goal is to do his best to make some contributions to the protection of plant diversity.

  The precision manufacturing engineer plunged into the botanical garden

  The interview with Yang Xiaoyang was held in a coffee shop. A few days ago, the position of his circle of friends showed that he had once again "gone down to the rainforest" and "the place was Sumatra, Indonesia". This is obviously not the first close contact with the rainforest of Sumatra. This time, he photographed the Titan konjac (also known as "corpse konjac" because of its stench) that is about to bloom. A few years ago, he took a photo with the flowering Amorphophallus konjac. Facts have proved once again that it is a myth to say that it can "eat people" when it blooms, and it stinks only to attract insects to pollinate it.

  Black-rimmed glasses, healthy wheat skin, and backpack. From the outside, Yang Xiaoyang is a typical "engineering male", slightly introverted and unsociable, but his eyes are shining when he talks about plants.

  Yang Xiaoyang was born in rural Henan, and was brought up by his grandmother. His childhood without his parents made him somewhat withdrawn, but the flowers and plants in the fields gave him endless happiness. "When I was a child, I was barefoot in the fields, and I especially liked to see weeds. At that time, I felt that the grass was actually very beautiful." Yang Xiaoyang said that when he was very young, he observed that geranium seeds would roll, and later he read in books that it did.

  After graduating from high school, Yang Xiaoyang chose to study in Singapore, majoring in precision manufacturing. Witnessed Singapore from "city garden" in the early years to "city in the garden" today, Yang Xiaoyang, who loved plants since childhood, was deeply touched by the progress of urban concept. After school, his favorite thing to do is to visit botanical gardens and nature reserves, which fully satisfies his desire for exploration and builds a basic understanding of plants in Southeast Asia. Stepping into the door of botany, Yang Xiaoyang wandered among them and enjoyed it, "like digging a treasure".

  From machinery makers to plants, it seems that there is no boundary. However, in Yang Xiaoyang’s eyes, plants themselves are a very precise series of expressions. Every plant is a product, but its manufacturing is more advanced. It is alive and does not need human drive.

  In 2013, Yang Xiaoyang, a college graduate, entered a local precision manufacturing enterprise in Singapore. In that year, Indonesia’s "Ba-burning Movement" got out of control, which led to the worst haze in Singapore’s history. Yang Xiaoyang said that this incident made him sad, because there may be many plant species that have not been discovered by the scientific community on those burned mountains.

  After the haze disaster, Yang Xiaoyang quit his job as an engineer and went directly to the rainforest in kalimantan island, Indonesia, where he wanted to find his own direction. After more than ten days of rainforest exploration, he said that he couldn’t walk at all, and there were too many unknown plants waiting for him to discover. After that, he strengthened his belief in doing something for plant protection. Later, south china botanical garden of Chinese Academy of Sciences extended an olive branch to him, and he was determined to devote himself to plant introduction and conservation.

  At the end of 2013, when I just returned to China, my friend gave Yang Xiaoyang a book "The Fruit Hunter" by Canadian Adam Reese goellner. Yang Xiaoyang thinks that the theme of this book is very well conceived, but from a professional point of view, there are many artistic processing elements, which are not the truth of science. In addition, there is no "fruit hunter" culture in China, so he decided to focus on the field of fruits from Southeast Asia.

  Recover a life from the mouth of a python by "the golden eye of fire"

  Since he decided to be a "fruit hunter" in 2013, he has almost traveled all over the important rainforests in Singapore and Malaysia. November of each year to February of the following year is the peak period of fruit hunting. He has to arrange his own itinerary according to the fruit period. He often runs out for a few days and is half dead. He comes back to sort out the information and rest for two days, and then starts again. Tragedy of making a trip in vain happens from time to time. Yang Xiaoyang told reporters that some time ago, he went to the Limeng area of Malaysia to look for a turtle durian. This durian is different from ordinary durian trees. Its fruit grows at the base of the trunk and looks like a group of turtles from a distance. Yang Xiaoyang was particularly excited. He told the local guide not to touch it in advance. He wanted to take a complete photo. However, the ripening season of the tortoise durian happened to be the Spring Festival in China. When he hurried there, all the fruits fell off. "It’s a week late, what a pity!"

  Yang Xiaoyang’s "golden eyes" have been trained by drilling in the rainforest all the year round. He can search for his target like a scanner in a large lush rainforest, and even find new plant species in the roadside Woods in a speeding car. Therefore, he is often ridiculed by friends in the same plant circle: "These eyes are worth over 100 million yuan."

  With these eyes, he once "picked up" a life. It was when he was looking for paramita in the tropical rain forest of Malaysia. From the sound of stepping on the leaves, he judged that it was a Malayan paramita. When he looked down at the fruit with his camera, an unusual object flashed by his feet. He subconsciously took a step back and looked intently. It was a baby python about three meters long. "I stayed there and didn’t dare to take pictures with the camera. The python was spitting letters and smelling my breath. If I stepped on it, I would be in trouble." Yang Xiaoyang said with a smile.

  In addition to pythons, he also met crocodiles, clouded leopards, Sumatran tigers, bears, etc. In Yang Xiaoyang’s view, the most dangerous thing in the rainforest is to meet people — — Real hunters. "Poachers carry guns. They don’t care what I do. They killed me in the rainforest. No one knows." He said that in some countries, before going to inspect, they will report to the local public security bureau, and the police will send people with guns to protect these inspection teams, so that poachers dare not hurt them.

  How can we find those target fruits in the vast virgin rainforest? Yang Xiaoyang told reporters that in addition to relying on his years of expertise in plant classification, searching according to the location recorded in plant specimens is also inseparable from the help of local guides. The guides grew up in the forest and knew a lot about all kinds of fruits, but later, it became more and more difficult to find the fruits he was looking for, and even the ancestors of the guides had never seen them. There will also be a situation where the guide stood him up. At that time, there was no time to find a second guide. What should I do? He had to bite the bullet and learn some Malay words in a week, so there was no problem in daily communication.

  Another good way to find fruit is to "soak" in the local fruit market, which is another treasure land, where he first saw the loquat awn with lavender-eyed nuts. Another time, in order to find a kind of fruit, we need to have a good relationship with the local indigenous people, and we have to help the indigenous fruit vendors in the traditional market sell fruit. "Business is not bad, and the indigenous vendors next to us are jealous." Yang Xiaoyang enjoys it.

  The fruit industry "Shennong" was accidentally poisoned.

  Because of "occupational disease", every time Yang Xiaoyang finds a new fruit, he must first take photos carefully. If local laws allow it, seal it with a fresh-keeping bag and take it home, then carefully "dissect" it under the light, observe its seeds and pulp, and then taste it carefully. In most cases, the principle he follows is to try a small amount on the spot after taking photos. "Every time I find a new fruit, that kind of joy will resolve all the hard work on the road." Yang Xiaoyang’s taste buds have been hit again and again — — After eating it, lemons are all sweet mysterious fruits, rice cake fruits with milk flavor that feel "electric shock" when put in your mouth, Elaeagnus mollis Thunb, which is 3,000 times sweeter than sucrose, and snakeskin fruit & HELIP; … Of all, Yang Xiaoyang thinks that the most shocking thing is Jinguangguo. Although it looks like a meteor hammer, the aroma of fruit juice is ten times more delicious than that of strawberries.

  Many people yearn for Yang Xiaoyang’s career, calling him "Shennong in the fruit industry", but in fact, he is very cautious about the fruit he has never eaten. In his words, "Otherwise, I may not be able to sit here and have tea and chat with you." In 2015, the world annona group led by him was inspected in a protected area in Guangdong, and experts found the ripe fruit of Guafu wood in the wild, which looked delicious. Experts began to taste it, and Yang Xiaoyang was moved when he saw it. First, he tried it with the tip of his tongue, no problem, and then he ate one. However, after a few minutes, he felt something was wrong, unable to speak, and his throat felt as uncomfortable as if he had been stabbed. Then he poured water and gargled wildly, but fortunately he didn’t eat much. After half an hour, he slowly recovered. Later, he learned that only some people are sensitive to guafu wood.

  Shampoo fruit must be on every tropical fruit hunter’s hunting list, and many British nobles are eager to find this kind of fruit. This is a magical fruit. It is said that after eating it, it smells fragrant all over. Even sweating, urinating and farting have a faint violet fragrance. It is only distributed in Java, Indonesia, and is exclusively for the royal family in Indonesia. The fruit hunter who hasn’t eaten shampoo fruit is not a real fruit hunter. Yang Xiaoyang finally found it with great efforts, but because of the previous poisoning experience, he didn’t dare to eat more, just licked a few mouthfuls, went back to the hotel and drank more water. When he felt it, he closed the bathroom door, and he quietly waited for the fragrance to emanate, but he didn’t. "Maybe I ate too little, but I believe the legend about it is true."

  Many fruits that Yang Xiaoyang found are rare or even endangered varieties, and many people will ask him where they found them. "I won’t expose these points casually, because I’m not sure what he wants to do, and he may destroy them. Only friends who are like-minded and know the roots will say it. "

  Sea coconut is called "woman’s ass fruit" because of its unique shape. It is only produced in Seychelles, and the fruit ripens only once every few years, and now it is endangered. Therefore, even if it is hard to find the trace of sea coconut, Yang Xiaoyang will give up tasting it. Another time, in the rainforest of Sumatra, he found some round fruit Du Ying. The stone inside looked very familiar. It was "King Kong Bodhi", and a six-petal one in China would cost several hundred yuan. After struggling for a little while, he still picked up only a few of the hundreds of fruits that fell from the ground for dissection and souvenir.

  There is no mine at home. I thought about opening a Taobao shop to sell durian to earn money.

  How many people are eager for durian, how many people avoid it. Yang Xiaoyang is an out-and-out "durian control". He has tasted more than 100 kinds of durians, and even a circle of various durians is placed around the WeChat avatar. Before he went to Singapore to study in 2008, he had never tried this kind of fruit with special taste. The first time I ate durian was in the corner near a small vegetable market. The durian was sold by an uncle who was about 50 years old and had a cigarette in his chest. After wandering in front of the booth for a long time, he carefully asked, "Aren’t durians all smelly?"? Why is this taste fresh and has no smell at all? " Uncle’s words have made him unforgettable so far. "The real durian is not smelly, and only those who don’t understand durian think it stinks."

  "A durian is as deep as the sea". Eating durian for the first time made him "happy and want to cry". Since then, he has made more friends who like durian and organized groups to look for delicious durian everywhere. The durian in Singapore couldn’t satisfy these senior durians, so they got a visa and set off for Penang, the legendary durian sanctuary. There, Yang Xiaoyang ate the old tree red shrimp durian, which can last for three months after a bite, as well as the famous Shanba durian, black thorn durian, centipede durian and Zhuge Liang durian & HELIP; …

  Yang Xiaoyang said that in fact, everyone’s understanding of durian in China is very shallow. For example, durian with an opening is mature, which is obviously a misunderstanding. Durian’s opening statement shows that it is not fresh. There is a single variety of durian in China, and the most famous one may be the golden pillow durian. If let Yang Xiaoyang score, out of 100 points, Golden Pillow Durian can only get 15-20 points. There are at least 600 varieties of durian in Southeast Asia. Why are so many varieties with better taste rarely seen in China? In Yang Xiaoyang’s view, it is precisely because we have few choices that we have misunderstandings about durian, thinking that golden pillows are the best. When durian growers see this situation, they will expand their planting, and gradually other varieties of durian will become less and less.

  Yang Xiaoyang wants to write a monograph on durian, which has not been done in China. His original intention is to let more people realize the diversity and beauty of durian through popular science. He doesn’t want to see more and more durian varieties die out because of the market. For the public, what we can do is to understand the diversity of durian, so as to choose independently and guide the market. After that, everyone will know more about the diversity of fruits, vegetables, food and so on, which will invisibly urge the public to protect the diversity of the whole plant kingdom. This is the mission behind the "fruit hunter" and the ultimate goal he has been pursuing.

  After Yang Xiaoyang’s experience went through a hot search, many people questioned it. As the media said, "Looking for fruit costs hundreds of thousands a year at their own expense". Is this afraid that there is no mine at home? He told reporters that he is separated from the "rich second generation" by ten Java islands, and the cost of being a "fruit hunter" is quite high. If all of them are taken by themselves, there are indeed hundreds of thousands. But many times, the search for fruit is linked with scientific investigation, and the local scientific investigation needs a plant taxonomist like him, which can bear a large part of the expenses. He even thought about opening a Taobao shop and selling durians to make money when it could not be maintained. In his first popular science book "Fruit Hunter in Southeast Asia", Yang Xiaoyang wrote: "I fantasize that I turned into a durian tree at night, standing proudly in the vast tropical rain forest, quietly watching the vicissitudes of life."

The British media introduced wuhan nightlife, and the comment area was too "imaginative"

[Compiled/Observer Network Tong Li] After opening a party in Wuhan Water Park caused many foreign netizens to discuss, foreign media focused on Wuhan’s nightlife.
Interestingly, some people think that Wuhan’s rich nightlife is a sign of success in fighting the epidemic, and reflect on the shortcomings of their own country; However, some people are sour. As always, they throw away the pot of China, not only hiding that Wuhan people have returned to normal life, but also speculating whether they have all been "vaccinated" or realized "group immunity" …
According to a report by Reuters on December 17th, Zhang Qiong, who was gathering with friends, wiped the birthday cake from his face in a crowded beer shop. She is 29 years old and "feels reborn after the COVID-19 epidemic and the unsealing".
Report screenshot
Some friends who attended the party went outside and played a game of toy guns and balloons at roadside stalls.
After Wuhan was unsealed for half a year, the nightlife in this city has been active again. At night, many young people will go out to eat snacks for entertainment.
After experiencing one of the strictest city closure measures in the world, Wuhan has not reported any new local cases since May 10th.
Students, musicians, artists and young office workers are the backbone of wuhan nightlife. They told the story of staying at home for months, and many of them took this opportunity to prepare for the urban recovery.
For example, Wang Xinghao, the lead singer of a local rock band, said, "Some of my new music is related to the epidemic period." One of the new songs was inspired by the three months he lived close to his mother.
Yi Yi, a rock music enthusiast, said after watching the performance: "Now everyone is out to eat and have fun. I don’t think there were so many people before the epidemic (here). "
The nightlife economy here has recovered after being hit hard, showing the lifestyle in the post-epidemic era. Many people hope that this lifestyle will become a reality in 2021 after the global promotion of COVID-19 vaccine.
At the end of the article, Zhang Qiong said, "I really want to cherish this time, because you never know when life will end, so let every day be happy and meaningful."
It is worth noting that Reuters posted this article on Facebook and Twitter, and the discussion was more heated than other articles.
The most liked comment on Facebook wrote, "This is what success looks like. Sadly, Trump prevented us from achieving such success. And all those ‘(covidiot idiots’. "
However, some people surmised that "they are celebrating the destruction of the world we used to know."
He declared that "I can’t imagine anything more unpleasant than hearing about the recovery of wuhan nightlife" and threw the pot of his country’s failure to fight the epidemic to China.
Some people are so imaginative that they can draw a conclusion from China’s success in fighting the epidemic and returning to normal life that "China obviously has a vaccine that has not been shared with other countries, or there is a virus that can be’ recycled’ in due course". Silently, there are people who praise this conspiracy theory.
So are all the Wuhan people "vaccinated" or "immunized in groups"?
"What did I miss? Who can explain to me why Wuhan can return to normal? Do they have a vaccine? Or did you achieve group immunity? What the hell happened? "
The answer is simple:
"They follow scientific advice, and not so many people oppose epidemic prevention measures."

Today, end this history completely!

Today, the Lijiang-Shangri-La Railway was officially completed and opened to traffic!

The Lijiang-Shangri-La Railway connects Lijiang City and Diqing Tibetan Autonomous Prefecture in Yunnan Province, with a total length of 139.7 kilometers. The opening to traffic also means that Diqing Tibetan Autonomous Prefecture, with an average elevation of 3,380 meters, has completely ended the history of no railways.

From Lijiang to Shangri-La, from Yulong Snow Mountain to Meili Snow Mountain, through meadows, forests and lakes, connecting cities, villages and fields, Xintian Road spreads on the snowy plateau. Let’s go to Shangri-La by train!

The fastest train from Lijiang Station to Shangri-La Station is 1 hour and 18 minutes. However, the railway started construction in 2014, but more than 20,000 builders fought day and night among the mountains for nine years.

Lijiang-Shangri-La Railway is located in the northwest of Yunnan Province, the southeast edge of Qinghai-Tibet Plateau, and the middle section of Hengduan Mountains. It is connected by bridges and tunnels all the way-34 new bridges and 20 tunnels are built, and the bridge-tunnel ratio is as high as 73.4%. The route leads from Lijiang Station, passes through Hutiaoxia and Xiaozhongdian Town to Shangri-La in the north, and the route is located at the front of the contact zone between India plate and Eurasia plate, which is one of the regions with the strongest crustal tectonic movement in China.

The mountains along the line are high and deep, and the maximum slope reaches 28.5‰, which is equivalent to a distance of 1000 meters. The height difference between the starting point and the end point reaches 28.5 meters, which is similar to the height of a 10-story building. The terrain and geological conditions are extremely complicated, and the construction difficulty is rare in China.

According to reports, during the construction of the entire Lijiang-Shangri-La Railway, the technical difficulties such as Yulong Snow Mountain Tunnel, Haba Snow Mountain Tunnel, large deformation of soft rock with high ground stress, long tunnel at high altitude, long rail transportation and pushing on large slopes have been overcome, and the Hutiaoxia Jinshajiang Railway Bridge built has set three world records. A total of 18 national invention patents, 34 national utility model patents and 39 provincial and ministerial construction methods have been applied for.

Large deformation of soft rock, high ground stress, high temperature and rich water … The geological conditions along the line are complex, which brings great challenges to the construction. In order to build this railway, it is necessary to open two extra-long tunnels buried deep in the hinterland of Yulong Snow Mountain and Haba Snow Mountain.

Yulong Snow Mountain Tunnel, the key control project of the whole line, has a total length of 14.7 kilometers, which is the longest tunnel in the whole line. It is located in the longitudinal valley of Hengduan Mountains and crosses six faults. Affected by high-risk adverse geological conditions, such as fault fracture zone, high temperature and abundant water, high ground stress, etc., since the construction started in 2014, the tunnel has experienced mud outburst, water gushing and collapse for 238 times, with the maximum water inflow of a single working face of 37,000 cubic meters, the large deformation section of surrounding rock of 7,719 meters long and the maximum unilateral deformation of 2.3 meters. The deformation almost intrudes at the speed visible to the naked eye, which is extremely rare at home and abroad, and every step forward is extremely difficult.

Haba Snow Mountain Tunnel, with a total length of 9.5 kilometers, is a Class I high-risk tunnel. For tunnels less than 10 kilometers, it takes only 3 minutes for the bullet train to pass through, but since the construction started in 2014, the builders have struggled for 9 years. Generally, the tunnel only needs one layer of initial support, while the Haba Snow Mountain Tunnel adopts three layers of initial support. "A tunnel with super-deep buried depth, high geostress and large deformation of soft rock like this is rare in China." Huo Erlun, head of the Lijiang-Shangri-La Railway Project Management Department of China Railway 16th Bureau, which built the Haba Snow Mountain Tunnel, said.

It should be especially mentioned that the Jinsha River Bridge, the world’s first long-span railway suspension bridge, is located at the junction of Lijiang City and Shangri-La City of Diqing Tibetan Autonomous Prefecture, with a total length of 882.5 meters and a main span of 660 meters. The vertical distance between the bridge deck and the river surface is about 250 meters, which is equivalent to the height of more than 80 floors. The erection of mid-span steel truss girder is "the first in three worlds": it is a precedent in the world to hoist 640 tons of large-tonnage steel truss girder with cable crane; The intelligent cable crane used for hoisting is independently developed and designed in China, with a maximum hoisting weight of 800 tons, which is the heaviest cable crane in the world at present. The height difference between the top of the cable tower and the steel beam assembly yard is 330 meters, which is the largest cable crane in the world at present.

Diqing has many world-class tourism brands such as Shangri-La, Three Rivers Parallel, Meili Snow Mountain and Ancient Tea-Horse Road. It runs through the National Highway 214 in Shangri-La City and Deqin County of Diqing Prefecture from south to north, and is known as "the most beautiful and lowest-key landscape avenue in China", which gathers Tiger Leaping Gorge, Little Zhongdian Flower Sea, Songzanlin Temple and balague Sect. Lijiang, Yunnan has three world heritages: Old Town of Lijiang World Cultural Heritage, Three Parallel Rivers World Natural Heritage and Naxi Dongba Ancient Books and Documents World Memory Heritage.

The bullet train will drive from Lijiang to Shangri-La, and the train will cross the Jinsha River to the north, pass through Xiaozhongdian to Shangri-La, and pass through famous scenic spots such as Yulong Snow Mountain and Tiger Leaping Gorge. The crossing area is a gathering place for ethnic minorities such as Tibetans, Yi and Bai, which will connect these world-class tourist attractions in series.

Get on the bullet train, Shangri-La of the world, waiting for you!

From the four major reforms of China’s medical system: Can money completely alleviate the conflict between doctors and patients?


guide reading

Big hospitals have kidnapped other hospitals, and all hospitals have to run wild on this system. All doctors are victims or victims.

Yesterday, "The Last Dopamine" WeChat WeChat official account posted an article "Where is the root of the conflict between doctors and patients? ",this is really a cliche. His answer is that there are many reasons for the tension and frequent conflicts between doctors and patients, and they are interactive.The main reason is: money!



There are frequent conflicts and disputes between doctors and patients. How did the doctor-patient relationship evolve?


A few years ago, an article in China Medical Tribune introduced the evolution of the doctor-patient relationship, and the graph of the evolution of the doctor-patient relationship reflected the doctor-patient relationship from ancient times to the present.


Figure 1 Evolution curve of doctor-patient relationship

The medical level in ancient times was very poor, and diagnostic tools and treatment methods were scarce.Doctors mainly care and care for patients.. The doctor-patient relationship is an equal friend relationship, there is no commercial and economic relationship, and the reward is dispensable.


In ancient times, many people died of illness, and most patients and their families were grateful for the help of doctors. If the doctor doesn’t cure the disease in the end, the patient can accept it.


With the development of history, doctors have become a fixed practice, and the development of medicine has improved the diagnostic tools and treatment level. There is an unequal patronage relationship between doctors and patients, and doctors still can’t effectively treat diseases, mainly listening to patients’ needs and prescribing some symptomatic drugs, and patients often pay generous remuneration. At this time, doctors are subordinate and serve patients. Although their status is unequal, the relationship between doctors and patients is still relatively harmonious.


With the gradual improvement of doctors’ status, doctors’ authority is growing, and doctors are increasingly relying on laboratory tests and report forms. Doctors communicate less with patients, which invisibly widens the distance between doctors and patients.The status of doctors is gradually rising, and patients’ right to speak is relatively weak. In such a doctor-patient relationship, the patient is no longer the dominant position, and is completely dominated by the doctors in the hospital, so the contradiction between doctors and patients gradually arises.


An article in the New England Journal summarized the history of medical system reform in China when commenting on the root causes of doctor-patient conflict in China.


Since 1949, China’s medical system has been divided into four stages:


1. the first stage: imitating the national medical system of communist countries (1949~1984)


The government owns and operates all medical institutions, and all employees are government employees.There is no need for medical insurance at this stage, because all medical services are almost free.


At this stage, China’s medical system has made a remarkable achievement, such as the decline of infant mortality and the mass elimination of some infectious diseases.


2. The second stage: the new economic rules were implemented in the medical industry (1984~2003).


China’s medical system began to turn around. The financial support provided by the government to hospitals has dropped sharply, and many health workers have lost their financial subsidies.The government still owns the property rights of hospitals, but it has little intervention in the behavior of medical institutions.In a market system lacking rules, these nominally public hospitals began to act like profit-seeking enterprises. Doctors employed in public hospitals can get a considerable bonus if they make a profit for the hospital.


At this stage, the government only provides medical insurance to some people, and private insurance companies do not exist at all; As a result, most people in China are not covered by medical insurance, which makes the turbulence caused by the experiment of market-oriented medical reform more intense.


By the late 1990s, this market-oriented reform experiment had led to public anger, distrust of hospitals and medical practitioners, and even developed into a widespread violent attack on doctors.In some underdeveloped rural areas, the dissatisfaction caused by looking down on illness has triggered public protests, which has threatened social stability.


3. The third stage: 2003 version of medical reform (2003-2008)


Adopt a medical insurance system (new rural cooperative medical insurance)Slightly subsidize the hospitalization expenses of the rural population to alleviate social protests.. This medical insurance requires hospitalization to be reimbursed, which reflects the fact that hospitalization expenses were expensive at that time and many rural families were poor due to illness.


Policymakers’ minds are all occupied by how to reduce the expensive hospitalization expenses, and they don’t realize that "in order to manage health, treat diseases and control expenses, strengthening primary health care is the key link".


4. The fourth stage: 2008-present


Policymakers have realized that the medical insurance system and hospitals need to undergo major reforms, otherwise social stability will be endangered.This time, the medical reform announced to abandon the experiment of medical reform mainly based on market principles, and promised that by 2020, affordable basic medical services could be provided to all the people.


At the end of the article, some main problems are pointed out. First of all, tertiary hospitals have successfully resisted the latest medical reform. Secondly, there are still a lot of inequalities between poor rural areas and rich areas. Third,To form a high-quality, reliable and professional group of doctors in China, we have to make a hard struggle.. In the past, a great legacy of China’s market-oriented medical reform was that the public generally believed that doctors put their own economic welfare above the interests of patients, and it was not easy to completely reverse this concept.



Can money completely alleviate the conflict between doctors and patients?

Finally, a dopamine said in its article, "If it is free to see a doctor, or only a very small amount of money is needed, I think the relationship between doctors and patients will be eased immediately." Is that really the case?


There are still some people who basically don’t need money to see a doctor. Are they satisfied with medical treatment? The answer is of course no.


Their experience in the environment and process of medical treatment is often very poor. Even if you don’t have to bear the medical expenses yourself, and doctors will not be restricted in medication and examination, you still can’t satisfy patients. If the final outcome of treatment is bad, conflicts will still occur.


Professor Hu Dayi pointed out in an interview that,The root of doctor-patient conflict is the marketization of medical and health care.. He said that after putting the whole medical service on the market, it is impossible for doctors to help patients make behavioral changes except over-treatment. After turning medical service into a complete business model, the contradiction between doctors and patients will certainly become more and more fierce. In the past 30 years, the development of hospitals has been pushed to the market, which has led to the monopoly of medical resources by many giant hospitals. Hospitals rely on making money from patients to increase operating income, buy equipment, build houses and give bonuses.Big hospitals have kidnapped other hospitals, and all hospitals have to run wild on this system. All doctors are victims or victims.


Academician Han Qide pointed out in an interview that the contradiction between doctors and patients is the progress of medicine and society.The improvement of medical effect leads to a great increase in patients’ expectation. When the untreated patients become a minority, it is more likely to produce psychological imbalance.. At the same time, with the development of medical technology, doctors have shifted almost all their energy and attention to technology, and getting along with patients has been put in a secondary position, and the distance between doctors and patients has become larger and larger. The direct consequence of the improvement of modern medical technology is that the cost and price of medical care have greatly increased. The increase of expenses will double the pressure on patients and decrease their satisfaction, which will aggravate the contradiction. He also stressed that doctors are facing life, and in any era, doctors’ moral requirements cannot be lowered, otherwise, combined with information asymmetry, medicine will become very terrible.



Where is the outlet of doctor-patient conflict?

Lao Liu’s mother, as a retired doctor who has undergone free medical care and the first medical reform, recently read some articles on medical reform policies shared by old comrades, and repeatedly pointed out that medical care should be restored to the previous free medical care system for all.She said, no matter which countries are poorer or richer than ours, they can realize free medical care. Why can’t we?


After listening to this, Lao Liu smiled indifferently, not to mention paying medical expenses for all patients, that is, ensuring the normal operation of public medical institutions at all levels, paying reasonable wages and allowances in full by staff, regularly updating and maintaining instruments and equipment, opening medical service institutions in areas lacking medical services and medicines, and ensuring the implementation of other social work such as public health, anti-epidemic work, health care and rehabilitation.The cost that the government needs to bear may be astronomical.If medical insurance is not charged and social security funds are not paid, the medical expenses will be even more alarming. With such a large population in China, how can the state realize huge investment in the health system through taxation? Although I don’t know much about the economy, it’s hard to achieve it by rough thinking.


When I was young, I remember that there might be only one or two antibiotics at that time, which was very cheap. Image examination is film machine and ultrasound examination, and blood examination is also very limited. The quantity of drugs is limited, and many diseases are not treated with drugs. At that time, it was simple and cheap to see a doctor once. Surgery is a direct operation, no endoscope, no robot, and lack of instruments and instruments, and the cost is relatively low.Perhaps free medical care was possible at that time, so it is too difficult to realize the development of medicine today.


Some countries can provide free medical care, or provide the most basic medical security, or build on the basis of high taxes, or the country has less people and more money. Looking back at China’s population of more than one billion and the level of medical development, it seems a bit difficult to go back to the past.


As pointed out in the book Chinese doctor-patient relationship,The conflict between doctors and patients is not only a moral problem, but also an institutional problem. Morality needs long-term construction, and the system can be effective in the short term.To solve the conflict between doctors and patients, the fundamental way out is to eradicate the drawbacks of the medical system and use "restructuring" to incite "change of heart". The book also points out that in a reasonable medical system, the interests of doctors and patients are the same. The lower the cost of patients’ treatment, the less the social medical expenditure, and the more rewards doctors get. In order to eliminate the crisis of trust between doctors and patients from the root, we must reform the medical system of supporting doctors with medicine and supporting doctors with machinery, so that doctors can eat by technology instead of selling medicine.


In recent years, medical reform measures have continued, from the procurement of drugs with quantity and the procurement of high-value consumables in sunshine, and the medical insurance policy has been constantly changing. Is the patient feeling well? Has the practice environment of doctors improved? Has the contradiction between doctors and patients eased? It’s still time to give an answer.


How do you feel after the medical reform?

Former agent: Bayern Chelsea Atletico Madrid are interested in Vlahovic, and Juve will seriously consider making an offer.

Live on May 20th. On the whole market radio station, former agent Brambatti talked about the future of Vlahovic, as well as the topics about Rome and Florence.

About Vlahovic.

"There are three teams interested in Vlahovic, namely Chelsea, Bayern and Atletico Madrid. I think Juventus will seriously consider these offers, and I don’t know whether they will get capital gains, because Vlahovic has joined for one year and amortized the salary cost for one year. From a technical point of view, I want to emphasize that if a young player wants to form his own characteristics and win something, there are only two ways, either to change the head coach or not to complain and continue to follow the current head coach. When allegri led Juventus to win the Serie A championship, he did not succeed in making his strikers more distinctive. "

About Rome and Florence

"They deserve to advance to the final, and so do Italian teams. Rome has made a lot of efforts, even beyond the technical level. Mourinho’s emphasis on defensive tactics is an illustration. In addition, I am happy for Florence, and I am very happy that they and Rome have entered the final. "

OpenAI makes opponents unable to play? ChatGPT’s use cost is greatly reduced: the range is as high as 90%

Artificial intelligence is undoubtedly the track of the current fire. As the price of processing power of Large Language Model (LLM) drops, it will help this technology to enter the mainstream faster.

Due to the fierce competition among big language model companies OpenAI, Anthropic and Cohere, this cost difference has dropped to only about 5%.

In order to enhance competitiveness, OpenAI directly cut the price of using this technology by 90%, which may be devastating to competitors.

In addition, the sharp price reduction of ChatGPT of OpenAI will allow more users to participate, and hardware manufacturers will also design higher-performance chips, such as NVIDIA H100 GPU.

However, Ori Goshen, co-CEO of AI21, said that most companies will not use the general model of ChatGPT, but need models trained for industries such as finance or medical care, or models trained based on a company’s own data.

The price reduction of ChatGPT is only the beginning. This technology will enter large-scale commercial use at a rapid speed, and it also shows OpenAI’s determination to seize the market. In the future, not many companies will have the strength to fight against it.

Writing robot: the protagonist of future literature?

Nowadays, more and more robots are creating famous literary works all over the world. For example, an AI robot named "Shelley" won the "H.P. Lovecraft" literature prize by generating horror stories. There is another robot writer, "Little GPT", who recently wrote a novel "Nobody knows".

What is the difference between these writing robots and traditional writers? The advantage of writing robots is that they can process a large amount of information and generate texts by using algorithms and deep learning techniques. In addition, they can constantly improve the text quality by virtue of their self-correction ability. This provides a new way of thinking for human authors and expands the possibility of literary creation.

However, writing robots also have many limitations. They lack the natural "soul" and unique way of thinking of human authors, and can’t translate their emotional expressions into words. Literary works need the combination of emotion, intuition, experience and historical background, which cannot be completely simulated by writing robots.
