"Car Public Opinion" Issue 23

Author Miao Jian Research Institute

May is an important period for the automobile market. Many new cars exhibited at the Shanghai Auto Show began to appear on the market one after another. Joint-venture brands and independent brands are competing to launch brand-new, mid-term and annual models, bringing more choices to consumers. This also makes the domestic auto market more exciting and interesting.

According to the statistics of Miaojian Information Public Opinion Monitoring Platform, in the TOP10 public opinion hot list of new cars listed in May, domestic brands dominated, and among the new cars listed, fuel/plug-in models accounted for over 60%.

40% of the new models were launched in this month’s list, mainly medium and large SUVs. Among them, the price is divided into multiple grades, the highest is 389,800 yuan (Chuanqi E9) and the lowest is 79,800 yuan (Baojun Yueye).

In the list, the old best-selling models Accord and LaCrosse are all replacement models. Small and medium-term models are all plug-in models except Seal, which is pure electric.

List of new cars on the market: the new Haval Xiaolong won the No.1 new car communication in May, and BYD dominated the list of three models.

Haval Xiaolong (brand new) is the model with the highest heat index this month. On May 15th, the launch conference of Haval brand new energy night and Haval Xiaolong series was successfully held in Beijing, officially releasing the brand new energy strategy of Haval brand and launching a brand new energy product-Haval Xiaolong series, with the starting price of new cars ranging from 139,800 to 179,800 yuan.

Nearly 6.5% of Haval Xiaolong’s sound volume is generated at the client. Know the car emperor, today’s headlines and Sina Weibo are the main communication channels, among which Weibo has 91,000 interactive voices, which is the second highest interactive car in this month’s list. "Intelligent four-wheel drive" and "travel audio-visual room" are the main communication points of Haval Xiaolong.

There were many hot spots in the launch of Haval Xiaolong. In addition to the introduction of new cars, Feng Mu, president of Great Wall Motor, launched the "Five Questions of the Soul" on the spot. In addition to expounding the current situation of China’s automobile market and the development prospect of Haval brand, Feng Mu also pointed out the bad practices of disrupting the market, such as friends raising the water army and worrying product quality, saying that some car companies regard "controlling public opinion as the primary productivity" and even commented that some car companies "won sales and lost the bottom line"

Guangqi Honda Accord (replacement) is another popular model this month, which was officially launched on May 20th. As an old-fashioned best-selling model, the new car was widely discussed and paid attention to during the listing period, and "brand-new" and "intelligence" were the main communication points.

Guangzhou Automobile Chuanqi brand continues to maintain the new strength and communication potential of "new cars every month".

During the listing of Chuanqi E9, Guangzhou Automobile Chuanqi 4S stores all over the country, with today’s headlines, knowing the car emperor and car home as the main positions, made a lot of momentum. The marketing text is short, matched with key words of product characteristics, emphasizing electricity and oil, four-fold luxury gifts and so on. Reflect saving and highlight preferential treatment.

Pre-sale release list: two brand-new models were officially unveiled, and Musa’s publicity momentum was strong.

In addition to the listed models, the models pre-sold and unveiled in May are mainly medium/large SUVs. Fuel vehicles account for 60%. There are two brand-new models, namely Beijing Hyundai Mussa and JAC Yttrium 3. Most of the other models were changed in the medium term.

On May 17th, MUFASA, a brand-new compact SUV product of Beijing Hyundai, officially announced its Chinese name-Musa, and started the pre-sale. Musa spread strongly, and "smart two rooms and one living room on board" was its main propaganda point.

On May 20th, the global pre-sale conference of Yttrium 3, an intelligent pure electric car of Jiangqi Group, was held in Hangzhou. Yttrium 3 (brand new) is Jianghuai Yttrium’s first intelligent pure electric vehicle. The new car is positioned as a pure electric small car with a pre-sale price of 97,900 yuan, focusing on "space, battery life and safety".

[2018 Online Media Ningxia Tour] Rice and Fishery Space Eco-tourism Park: the "online celebrity" of leisure tourism in Yinchuan Metropolitan Area

  At 22: 00 on August 14th, Hualong. com (special correspondent Luo Hao) On August 14th, more than 50 online media reporters from the northern line of Ningxia, a national online media, came to Ningxia Rice and Fishery Space Ecological Leisure Sightseeing Park in Sishilidian Village, Changxin Township, Helan County, Yinchuan City after finishing the interview in Shizuishan City.

  When I got off the bus, a neat piece of rice fields came into view, followed the steps to the observation tower in the garden, climbed high and looked far, and the pastoral scenery of full of green was panoramic. Different varieties of colored rice also made the online media reporter shout, "No wonder Yinchuan has ‘ Plug in the land of fish and rice in the south of the Yangtze River ’ The reputation of ".

  In 2016, Shilidian Village, Changxin Township, Helan County established Guangyin Rice Industry, Rice and Fishery Ecological Industry Sightseeing Park. In 2017, a rice fishing space was established, covering a total area of more than 3,600 mu.

  The rice and fishing space makes full use of agricultural and environmental resources, and builds a Yellow River Jin ‘an leisure agriculture industry demonstration base which integrates organic rice characteristic ecological agricultural production, fishery breeding, catering and fishing, sightseeing, leisure and entertainment, wedding photography, organic agricultural product processing, e-commerce sales and farmers’ training.

  "It’s not that I boast, we are really a leisure tour in Yinchuan metropolitan area ‘ Online celebrity ’ Point, it became a fire as soon as it was established last year, and a large number of tourists flocked to this piece of land with paper and rice and grass as pigments ‘ Painting ’ An idyllic complex. " Zhao Jianwen, the person in charge of the rice and fish space, said, "This place is not only suitable for gathering relatives and friends, but also suitable for bringing children to play. Children like to touch fish and pick up duck eggs in rice fields very much. According to statistics, in 2017, the rice fishing space received a total of 190,000 tourists, and it reached 150,000 in the first half of this year.

  Rice and Fishing Space has also conducted all-round training for leisure and organic agriculture practitioners, and radiation has driven 500 farmers to become rich.

  The innovation of the spatial pattern of rice and fishery is not only a beneficial exploration of the pilot work of the integration of the three industries in Helan County in recent years, but also provides important technical support and demonstration for the economic development of "agriculture+tourism" in the whole region. In recent years, leisure agriculture and rural tourism in Ningxia have developed rapidly, with nearly 900 related business entities, benefiting 170,000 farmers.

Mistaking bald heads for football AI’s poor eyesight is not only due to less training.

  Ai growing pains

  Editor’s note In recent years, artificial intelligence has developed rapidly and its application fields have been expanding. However, at the same time, AI "rollover" cases are frequently searched. Based on this, this edition opens the column "AI Growing Pains" to focus on AI "rollover" events, analyze the phenomenon, analyze the reasons, explore the solutions, and look forward to its growth.

  Intern reporter Dai Xiaopei

  After the game, it is probably unprecedented for fans to ask referees to wear hats or wigs.

  At the end of October, Scottish fans experienced an "unforgettable" football match. In the Scottish Football Champions League match between Furness and Elven, the AI cameras on the sidelines turned a blind eye to whether the players passed the ball or attacked with the ball. Instead, they followed a linesman and took a close-up of "C position" from time to time. It turned out that the AI camera mistakenly identified the referee’s bald head as a football, so he chased the whole game crazily.

  Fans who watched the 90-minute game at home spent most of their time not watching the ball, but watching the bald heads. Many netizens joked that this game really "saw a loneliness".

  Why does the AI camera regard the bald head as a football? What do we need to do to prevent AI from making similar mistakes? Can you think that AI is "weak" when there is a "rollover" incident?

  Unconscious "provocation" from bald referees

  From direct participation in sports events to recording athletes’ performance, to live broadcast of competitions and analysis of athletes’ health status, AI is becoming the darling of the sports world. A few months ago, Barcelona Football Club (Barcelona) also joined hands with video technology company Pixellot to create an artificial intelligence coaching solution.

  Unexpectedly, AI, which has made great strides in sports, unexpectedly encountered an unconscious "provocation" from a bald linesman. Because the linesman’s bald head is too bright and the sun shines, the AI camera can’t tell which is the ball and which is the head. Previously, because the Furness team said that the AI tracking technology they used could clearly transmit the live images to the homes of every season ticket buyer, so that fans who could not go to the home due to the COVID-19 epidemic would not miss any game.

  It is reported that the camera used in the live broadcast of this competition is the multi-camera system provided by Pixellot, which cooperates with Barcelona. The system is powered by NVIDIA’s graphics processor (NVIDIA GPU), and the captured video resolution can reach 8K. These cameras can be installed in a fixed position without being manipulated by the camera operator. In order to capture the key moments, Pixellot collected hundreds of thousands of hours of sports videos to train its algorithm on the NVIDIA GPU of the local workstation.

  With a huge amount of available data, using deep learning algorithms and high-performance GPU computing blessing, it has three major driving forces to push AI forward. Why did Pixellot’s AI camera "roll over"?

  After the event, the relevant clubs and the technology companies that make cameras reflected. The problem seems very clear: the size and shape of football are similar to those of a human head, and the direct sunlight makes the AI camera fall into "confusion". I hope this will not happen again, because the Furness team responded that it knew the problem and will improve the next game to bring a better experience to the audience.

  Pixellot also said that it is not difficult to solve this problem. The existing target detection and tracking technology is mature. Pixellot didn’t consider the influence of bald head in the design stage, so it needs to collect some data of football and bald head to fine-tune the algorithm to eliminate the interference from bald head.

  Some technicians said that not only "this is a ball" data set, but also a "this is not a ball" data set is needed when training the AI camera of the live ball game. Bald head, bright white shoes, lighting, balls on the training ground next to the competition field and balls used by players to warm up are all interference factors that need to be considered when training AI.

  AI "poor eyesight" is the norm.

  Although the performance of AI cameras can be improved by increasing data "feeding", strengthening training and improving algorithms, some professionals believe that with the gradual expansion of AI application scenarios, such "rollover" incidents will exist for a long time.

  “AI‘ Rollover ’ It’s normal, no ‘ Rollover ’ It’s strange. " Professor eecs and Huang Tiejun, president of Beijing Zhiyuan Artificial Intelligence Research Institute, spoke frankly when interviewed by Science and Technology Daily reporter.

  Huang Tiejun believes that on the surface, the failure of the AI ? ? camera may be due to insufficient pre-training, but the main reason is that the current computer identification system is only trained with specific data. For example, in the above example, the neural network trained with a large number of football videos has surpassed humans in identifying football, but it ignores that this network is more sensitive to bald heads.

  It is common to recognize or "turn a blind eye" unknown objects at random.

  Machine vision is to endow the machine with visual perception, so that the machine has the scene perception ability similar to that of biological vision system, which involves optical imaging, image processing, analysis and recognition, execution and other components.

  "Take the camera as AI ‘ Eyes ’ In real scenes, there is still a long way to go for AI to recognize football and baldness like human eyes. " Huang Tiejun said.

  When can I finish this road and even realize that the eye of AI surpasses the human eye?

  It depends on when machine vision will bridge the gap with biological vision. "The brain in the skull senses the outside world in real time through more than 3 million nerve fibers, of which there are more than 1 million behind each eye." Huang Tiejun said, "The machine vision developed to this day is still a drop in the bucket compared with the biological vision system that took hundreds of millions of years to evolve."

  The human eye has strong adaptability, can identify targets in complex and changing environments, has advanced intelligence, and can use logical analysis and reasoning ability to identify changing targets and summarize laws. On the other hand, machine vision can use artificial intelligence neural network technology, but it can’t identify the changing target well. Due to the constraints of hardware conditions, the current general image acquisition system has poor color resolution.

  "Compared with biological visual neural networks, the visual neural networks of artificial intelligence are far apart in structure and scale, so their functions are much worse." Huang Tiejun said, "In real applications, machine vision ‘ Rollover ’ It is not an accident. It is only a case to identify the bald head as a football. Similar problems actually exist in large numbers. "

  Huang Tiejun said: "This time, the technology provider can make up for the loophole that the bald head mistakenly thinks of football, but there are still more loopholes. Deceiving the face recognition system with antagonistic picture training is only the tip of the iceberg."

  Different technical routes are racing.

  "Machine vision based on deep learning has made great progress in image recognition, but it has not really solved the perception problem." Huang Tiejun believes that deep learning is far from grasping the complexity of human visual system.

  Deep learning is based on the training of image and video big data, which is far from the biological vision that actively perceives the dynamic world, and it is still not out of demand for computing power. For example, if the video frame rate is increased from 30 to 30,000, the computing power of deep learning needs to be increased by 1,000 times.

  Biological neural network is a pulse neural network, which is more suitable for completing visual information processing. Huang Tiejun believes that learning from the neural network structure and information processing mechanism of biological vision system and establishing a new set of brain-like vision information processing theory and technology is the hope of restarting machine vision.

  Experts said that there are two main technical routes to develop artificial machine vision. One is to build a powerful intelligent system by collecting more data, increasing the amount of data and strengthening training; The second is to imitate the biological nervous system, follow the gourd painting gourd ladle, clarify the structure and even mechanism of the biological nervous system, and develop future intelligence on this basis.

  Huang Tiejun believes that the second path is more effective than the first one. "In a short time, the first one is easier to achieve results. But in the long run, it is more direct to start with biological neural networks and more confident to achieve the goal. "

  At present, most AI scholars support the first path, that is, to develop artificial intelligence including machine vision through "big data+big computing power". Huang Tiejun set foot on the road taken by a few people because he firmly believed that the biological visual neural network had great potential to be tapped. "Biological brain is the product of hundreds of millions of years of evolution, and it is the best transcendental structure. Powerful intelligence must rely on complex structures and stand on the shoulders of evolution. It seems difficult, but it is the fastest. "

  Turing, the "father of computer science", has long expressed his admiration for the biological brain. At the beginning of 1943, Shannon suggested that "cultural things" could be instilled in the electronic brain. Turing once retorted in public: "No, I’m not interested in building a powerful brain. What I want is just an ordinary brain, just like the head of the chairman of AT&T."

  Is developing machine vision, or artificial intelligence, starting from scratch, imitating biological neural networks, or is there another way? There is no conclusion yet. On different tracks, artificial intelligence is accelerating.

  Although there are many cases of AI "rollover", such as the practicability of Google AI eye disease diagnosis system is greatly reduced in Thailand, Tencent AI translation made a joke at the Boao Forum in 2018. But the AI era is accelerating and unstoppable.

  "It must be admitted that AI has indeed solved many practical problems, and it will gradually replace some functions of people. But we can’t exaggerate it too much. It is still far from our imaginary intelligence and needs more breakthroughs. " Huang Tiejun said that to keep an open mind and bridge the gap between "experimental simulation" and "real world", the development of AI technology has a long way to go.

The growth rate of national land sales revenue has accelerated, but third-and fourth-tier cities are still declining.

  The amount of land supply is related to the trend of the property market. According to the latest official data, the national land transfer income has turned from decline to increase, and the total supply of real estate land is approaching the same period last year, but the third-tier cities have fallen sharply.

  According to the data of the Ministry of Natural Resources, from January to August this year, the national real estate land supply was 82,300 hectares, a slight decrease of 1.6% year-on-year. Judging from the data of real estate land supply in the last three months, although the supply of real estate and residential land in the country decreased year-on-year in the first eight months, the reduction rate narrowed month by month; Among key cities, the supply of real estate and residential land in first-tier cities maintained an increasing trend year-on-year, and the growth rate expanded month by month.

  In terms of cities, real estate and residential land in first-tier cities have increased year-on-year. From January to August this year, 70 large and medium-sized cities provided 30,700 hectares of real estate land. The supply of real estate land in the first, second and third tier cities increased by 6.2%, 1.9% and 9.0% respectively, and the supply of residential land increased by 19.6%, 1.4% and 13.6% respectively.

  According to the data of the Ministry of Finance, the national land transfer income in the first eight months of this year has exceeded 3.7 trillion yuan, and the year-on-year growth rate is further accelerated than that in July.

  Ministries regulate the land market.

  Throughout the year to date, the domestic land market has gone through several stages from downturn to rapid warming and falling, and the current signs of land market cooling are more obvious.

  According to the data of the Central Plains Real Estate Research Center, in August this year, 70 large and medium-sized cities in China (corresponding to 70 housing price cities announced by the National Bureau of Statistics) had a total of 1057 land transactions, with a land transaction amount of 250.1 billion yuan, and the land transaction premium rate was only 8%, which was significantly lower than that in previous months. Judging from the land market situation, the recent expectation of tightening financing in the real estate sector gradually affected the land market.

  Zhang Dawei, chief analyst of Zhongyuan Real Estate, believes that, on the whole, the land markets in various places were relatively depressed in January and February this year. With the increase of credit market after the Spring Festival, the financing difficulty of housing enterprises has decreased. In April, the land markets in some cities showed signs of recovery, and the land markets in first-and second-tier cities continued to heat up, with the monthly land transaction amount of more than 300 billion yuan and the premium rate maintained at around 20%.

  Stabilizing land price is an important goal of real estate regulation and control in 2019. The rapid warming of the land market since the second quarter has attracted the attention of the regulatory authorities, and relevant ministries and commissions have successively taken action.

  In April this year, in order to achieve the goal of city-specific policy and classified regulation, maintain a stable supply of residential land, and guide market expectations, the General Office of the Ministry of Natural Resources issued a notice requesting that the "five categories" of residential land regulation targets be formulated and implemented in 2019.

  The notice requires that land supply should be stopped in cities above prefecture level, counties (county-level cities) with a population of more than one million, and commodity housing inventory digestion cycle is more than 36 months; For 36 to 18 months, the land supply should be appropriately reduced; For 18~12 months, maintain a flat level of land supply; 12~6 months, to increase land supply; For those less than 6 months, the land supply should be significantly increased and accelerated.

  Another Ministry of Housing and Urban-Rural Development, which is responsible for the regulation of the real estate market, also began to warn some cities where land prices and house prices rose too fast in April and May.

  In July, the new policies on real estate trust and overseas financing were introduced continuously, which had a certain impact on the real estate land acquisition policy. Since then, the premium rate of hot land began to decrease. In August, the number of operating land in 70 major cities increased significantly, with a total of 72 cases being the highest in the year.

  "The land market, like the property market, is only allowed to appear in Xiaoyangchun, but not in summer. Once the land market is overheated, the possibility of upgrading the policy is not ruled out. " Zhang Dawei said that since August, the land market has entered a stage of rapid fever reduction.

  According to the data of Zhongyuan Real Estate, the data of land acquisition by real estate enterprises also showed a significant decline. In August, the land acquisition by major real estate enterprises decreased significantly. Only eight domestic enterprises acquired more than 5 billion yuan, the highest of which was Vanke’s 15 billion yuan, followed by Poly’s 9.2 billion yuan, Jinmao’s 6.8 billion yuan, Sun Hung Kai’s 6.6 billion yuan and China Resources’ 6.4 billion yuan.

  Yan Yuejin, research director of the think tank center of Yiju Research Institute, also believes that in the second quarter of this year, the central government paid great attention to the overheating of land prices in some cities, and the policy fundamentals were tightened again, especially the tightening characteristics of the financing market were the most obvious, which made it more rational for real estate enterprises to purchase land in the third quarter.

  Third-and fourth-tier cities have obviously cooled down.

  In recent years, the regional characteristics of China property market have become more and more obvious, the trend of the real estate market has been divided, and the pricing of non-quality land by housing enterprises has been lowered. But the competition for high-quality cities and high-quality land is still fierce. Although the regulation policies of first-and second-tier cities are strict, for housing enterprises, in order to increase sales, they will still concentrate on land acquisition.

  While the first-and second-tier land markets maintain a high degree of heat, the land markets in third-and fourth-tier cities show signs of falling back. According to some statistics, since 2019, the land market in third-and fourth-tier cities has not performed as well as last year due to the tightening of shed reform scale and the early overdraft of some demand.

  According to the data of the aforementioned Ministry of Natural Resources, the supply of real estate land in third-tier cities decreased by 9.0% from January to August this year, and the supply of residential land decreased by 13.6%.

  Shanghai Yiju Real Estate Research Institute’s latest issue of "China Baicheng Homestead Transaction Report" shows that from January to September 2019, the transaction area of residential land in 64 third-and fourth-tier cities was 144.88 million square meters, down 7.1% year-on-year. Compared with the trend of first-and second-tier cities, the cooling characteristics of the homestead market in third-and fourth-tier cities are obvious. At the beginning of the past two months, the cumulative homestead transaction area has continued to expand year-on-year, further reflecting the characteristics of market cooling.

  Yan Yuejin, research director of the think tank center of Yiju Research Institute, said that from January to August, due to the influence of policy control and market expectations, the growth curve of related land purchases declined slightly, which fully reflected the cooling trend of the homestead transaction market. From the structural point of view, the cooling trend of third-and fourth-tier cities is more obvious, which is related to the problem that such cities are facing inventory backlog again.

  "From the reason, the current residential transaction market in third-and fourth-tier cities has cooled down and is facing the pressure of destocking again, which will dampen the enthusiasm of housing enterprises to replenish homesteads; At the same time, it also affected the capital withdrawal of housing enterprises and continued land purchase. " Yan Yuejin said.

  The growth rate of land sales revenue accelerated.

  The stabilization of real estate land supply at the national level has also affected the change of land transfer income.

  Since April this year, the Ministry of Finance has no longer disclosed the specific amount of revenue from the transfer of state-owned land use rights in the monthly financial revenue and expenditure, but only released the year-on-year changes. Judging from the data of the past few months, the land transfer income has achieved year-on-year growth in July after experiencing a decline at the beginning of the year, and it showed an accelerated growth trend in August.

  According to the data of the Ministry of Finance, from January to August this year, the national land transfer income increased by 4.2% year-on-year. From January to July this year, it was a year-on-year increase of 3.1%.

  In the first eight months of 2018, the income from the transfer of state-owned land use rights was 3.7 trillion yuan. In 2018, it reached 6,509.6 billion yuan, a year-on-year increase of 25%, and the total amount reached a record high.

  At the beginning of this year, due to the "worry" that the land market started in the second half of 2018 was cold and the phenomenon of land auction increased, many places also lowered their land transfer income expectations this year when preparing the government fund income budget for 2019.

  Yan Yuejin said that the current control of stable land prices is very strict. Recently, some hot cities have also actively carried out major inspections of the banking system. One of the contents is to check whether there are illegal funds entering the land purchase market.

  "It is expected that the residential land market will be characterized by cooling in September, especially considering that the current financial pressure of housing enterprises has begun to increase, so it is expected that housing enterprises will be conservative and tend to be rational. Of course, we need to look at September ‘ General drop+targeted cuts to required reserve ratios ’ The effect of policy. If the activity of residential transactions increases significantly, the enthusiasm of housing enterprises to subscribe for residential land in the fourth quarter may increase. " Yan Yuejin said.

  From 2011 to 2018, the national land transfer income was 3,316.6 billion yuan, 2,842.2 billion yuan, 4,125 billion yuan, 4,294 billion yuan, 3,254.7 billion yuan, 3,745.7 billion yuan, 5,205.9 billion yuan and 6,509.6 billion yuan respectively.

  There are still four months before the end of the year. If the current situation can be maintained, the income from land sales in 2019 is expected to exceed 6 trillion yuan again.

Spring full of mountains

  The scenery of Dahe Town in Tongzi County. Photo by Cheng Yong

  After a night of spring rain, Shan Ye, who had been sleeping for the whole winter, gradually stretched out. In the Dalou Mountain Range, spring is gradually sprouting in the mountains. On both sides of the road, there are peach blossoms, plum blossoms, camellia and rape blossoms … … The colors are intertwined with the green hills, just like a beautiful picture.

  We went to shi niu cun, Dahe Town, Tongzi County, Guizhou Province, to visit the 80-year-old afforestation model Weifafu. Starting from the county seat, the sky is already dawn. The car passed through the thick morning fog, passed the famous 72-way turn, and entered shi niu cun eastward. More than 300,000 Chinese fir trees planted by the Weifafu family grew on Daping Mountain at an altitude of more than 1,000 meters. The sun gradually dispels the morning fog. In the distance, the vast forest of Daping Mountain is as clean and green as washed in the spring sunshine.

  Along the mountain road, we walked into a green ocean. In the forest, the air is particularly fresh and cool, and the smell of flowers, trees and soil is everywhere. On a hillside, the old man in Weifafu was seen leaning over to pick up garbage in the forest with a bamboo basket on his back. When the old man saw us, he stopped what he was doing and came to shake hands with us with a smile. The old man is in high spirits and energetic, with a faint dew on his gray hair and grass clippings on his rubber shoes. His palm is wide and rough, with thick calluses.

  The sun shines obliquely on the straight fir trees from high places through the dense forest. A few birds are jumping on clusters of new leaves, twittering the news of spring.

  "You see, the tree, the bird came. When birds come, there are fewer insects. Bird droppings are rich in soil and trees are growing well. " The old man touched a stout fir tree and said happily.

  "Did you plant all these trees?"

  "More than that, there are more than 1,100 mu." The old man led us to a high place and pointed to the mountains in the distance: "These mountains are the farthest. If you walk, it will take a whole day to get there."

  I looked up and couldn’t see the farthest hill. It’s hard to imagine how hard it took Wei Fafu’s family to plant small saplings into today’s towering trees by shouldering their backs and walking dozens of miles of mountain roads.

  Speaking of afforestation, Wei Fafu has a lot to say. In 1950s and 1960s, due to excessive reclamation, the ecological environment of Daping Mountain was worrying. At that time, Wei Fafu often wandered alone on the mountain, looking at the barren mountain, listening to the mountain wind raging on the bare mountain, rolling up the dust all over the sky, and his heart seemed to be tightly pulled.

  In the spring of 1985, Wei Fafu, then the production team leader, decided to return the sloping farmland to plant trees. His decision was supported by his family. He applied to the village collective for contracting, signed a contract for greening barren hills, and received seedlings subsidized by the county forestry bureau.

  Since then, Wei Fafu’s family began to plant trees. In order to speed up the progress, Wei Fafu raced against time like clockwork. There is only one thought in his heart: "plant a variety of trees and turn the barren hills green as soon as possible."

  "Every day, at dawn, our family set off, and everyone was carrying hundreds of pounds of saplings. Two red marks were pulled out of the shoulders, and water bubbles were ground in a few days. The slope is steep and the road is far away. We only eat two meals a day, and the time saved is used to hurry. At the end of the day, the coat is often soaked with sweat, the pants are covered with dew, and the whole body is wet. " The old man still remembers the scene at that time.

  However, in the first spring, because of the serious soil erosion, low soil water storage capacity and lack of experience in planting trees, the planted trees only lived for a small part. Wei Fafu rallied and ran out of water, so they carried Mizukamiyama. He works in the forest for ten hours every day, and the action of planting trees is becoming more and more skillful. He scraped the soil with one hand and held the seedlings with the other, straightened the roots and carefully put the seedlings into the pit. Fir and pine seedlings are leafy and hard, and often prick their fingers, so he uses soft ant nest soil to stop bleeding and relieve pain. In summer and autumn, he went out early and went back to the forest to pull weeds. Even in the cold winter, he still patrols the mountain forest every now and then. After a year, he has worn out more than ten pairs of shoes. This year, the survival rate of saplings was as high as 90%.

  Speaking of the trick of planting trees, the old man smiled: "Planting trees is the same as being a man. The roots of saplings should be buried deeply and kept straight, so that they can easily take root in the earth."

  One minute, nine in charge. In order to afforest, he opened up a 10-mu nursery, and some seedlings were self-sufficient. He also set up a brick and tile factory to exchange all the bricks produced with villagers for working hours, so as to increase the labor input for planting trees. Winter goes and spring comes, year after year. Ten years later, with the efforts of Wei Fafu, the barren hills of Daping Mountain gradually became green, and the once-cut mountain spring water was restored, which solved the problem of drinking water and irrigation for local villagers.

  Someone once offered Wei Fafu a high price to transfer the forest, but Wei Fafu refused. He said: "for so many years, I have done it for green mountains and green rivers. Trees are my children. Trees are more important than money." In thirty-seven years, under his careful care, the mountain forest has never suffered a mountain fire. Today, the old man still insists on going to the Woods every season. The time with the tree became an indispensable part of his life.

  His contribution is gradually known to more people. He won back the honors of Guizhou moral model and Guizhou labor model. Now he still has a wish, and that is to join the Communist Party of China (CPC) as soon as possible. In May 2021, 79-year-old Wei Fafu submitted an application for joining the Party, which is the oldest applicant in shi niu cun’s history.

  In the distance, the breeze is Xu Lai, and the green waves are rippling in the forest. Listen, the branches and leaves rustle in the wind, as if the castle peak is greeting the old man.

81 movies get together for the 40-day Lunar New Year, waiting for the "head work"

  Zhong Han Jian gong bo

  "Is it a New Year’s Eve file now?" Not long ago, Hu Youqi, a citizen, found on the ticketing platform that the platform and the cinema had already marked the Lunar New Year file early, and many recently released films also used it as a label for publicity.

  Data from Cat’s Eye Professional Edition shows that this year’s Lunar New Year file runs from November 24th to December 31st. As of 16: 00 on December 18th, 81 films (including reruns) have been locked in this schedule, and the national box office this year has exceeded 52.906 billion yuan. With the further promotion of the Lunar New Year file, people in the industry generally believe that this year’s movie box office will hit 55 billion yuan, which is the same as 2017.

  Many viewers found that, unlike the impression that the New Year’s Eve files are mainly comedic family movies, this year’s New Year’s Eve files are not only rich in types, but also have a good reputation. However, compared with previous Chinese New Year’s Eve movies, which have produced many annual box office champions and box office masterpieces that broke 1 billion yuan, Across the Furious Sea, which topped this year’s Chinese New Year’s Eve movie, currently has a box office of only 546 million yuan, lacking a "head work" matrix with a double harvest of box office reputation to drive the film market to by going up one flight of stairs.

  Has the New Year’s Eve changed?

  There is no standard answer as to when the Lunar New Year file will start. Usually, a movie is a hit around December, even if the Lunar New Year file is opened.

  On November 30th, the film "Hot Search" starring Zhou Dongyu, Song Yang and Justin was released, saying that it was "the first to open the curtain of the year-end Lunar New Year"; On December 1st, NI YAN and Seven starred in the film Goodbye, Li Kele, which is also called "the first shot of Chinese New Year". Hu Youqi has some doubts: "Isn’t the New Year’s Day to the Spring Festival?"

  In fact, with the development of the film market in China, the time of the New Year’s Eve is quietly changing.

  When will the Lunar New Year file become a schedule? The reporter interviewed a number of people in the industry, and almost everyone agreed that this concept entered the film industry in China, which originated from the film Party A and Party B, which was released at the end of 1997 and was dubbed as the "New Year’s Film", which made a box office story at that time. Since then, more and more films have chosen to be released during this period, among which the head films are often star-studded and commercial.

  Previously, the industry once divided New Year’s Eve files into broad and narrow sense. The broad New Year’s Eve files include two major festivals, New Year’s Day and Spring Festival, which last for about one and a half months. There is no standard answer as to when the Lunar New Year file will start. "Usually, a movie is popular around December, even if the Lunar New Year file is opened".

  Wang Ce, a member of the Shanghai Film Criticism Society and a senior screenwriter, said that the Lunar New Year file continued the idea that many lively comedies in China and Hong Kong were shown together during New Year’s Day and Spring Festival. "But at that time, the film supply was small, and the cycle of a film was as long as one to two months. With the increase in film supply, it has now been subdivided into multiple schedules. "

  On the movie data platforms such as Cat’s Eye and Lighthouse, the New Year’s Eve file is different from the New Year’s Eve file, New Year’s Day file and Spring Festival file. The New Year’s Eve file refers to more than one month from late November to December 31, while the New Year’s Eve file only refers to a day on December 31. There are still many cases of "stalls" in one day, such as Tanabata stalls and 520 stalls, which have emerged in recent years. According to insiders, the film market is now well supplied and the film screening cycle is shortened. Often, the first week or even the first day of the box office determines the follow-up trend of a film box office. In this case, it is not unexpected to subdivide the schedule. The film will arrange the release time according to the theme, investment and market expectation. Wang Ce said that the Spring Festival is a big schedule. Usually, films with larger investment and higher expectations will be released, and films with less competitiveness will be released on New Year’s Day.

  A few days ago, the reporter saw in Daguangming Cinema that the December News posted at the gate of the cinema was a collection of 13 films such as Hot Search and Wonka from Aquaman 2, and posters of recently released films such as Three Battalions, Crossing the Sea and Breaking Point were placed in the hall, but the words "New Year’s Eve File" did not appear. The staff of Daguangming Cinema introduced that in the past, the concept of New Year’s Eve was relatively broad, basically starting from the end of November and early December until the Spring Festival, but now it is gradually subdivided into New Year’s Day and Spring Festival. "We usually say New Year’s Eve, which generally means that when the New Year is approaching, at least after the end of December, it will start with Party A and Party B at the earliest, and then a series of films such as Let Bullets Fly, It’s too embarrassing for people to travel again have good box office output in this period. After the breakdown of the schedule in recent years, the atmosphere of the Lunar New Year file is not as strong as before, and the explosion point is more concentrated in the Spring Festival file. "

  "The concept of the schedule is more of a B-end concept. For the audience, the centralized release of the demand for watching movies is often accompanied by legal holidays, and the main box office output of the Lunar New Year file is still on New Year’s Day and other festivals." Zhang Tong, a senior analyst at Cat’s Eye Research Institute, said that in 2010, 2011 and 2012, domestic box office champions, Let Bullets Fly, flowers of war, and The Way of Water, were all released in the New Year’s Eve file. In recent years, the New Year’s Eve file also produced Sheep Without A Shepherd’s Ip Man 4, Shock Wave 2’s manslaughter 2 and Avatar: The Way of Water. "Famous in 2021 and Nobody in 2018 were both released in mid-November, and both of them have achieved good box office results in the traditional off-season of the film market."

  Can it hit 55 billion yuan?

  This year is the year with the most and most lively New Year movies, but there is still a lack of "head works" with a double harvest at the box office.

  The film market in China has recovered strongly this year. Data from Cat’s Eye Professional Edition shows that this year’s Spring Festival file became the second in history with 6.765 billion yuan; After that, the box office of the "May 1 ST" file was second only to the same period in 2019 and 2021; The box office of the summer file exceeded 20.62 billion yuan, breaking the record of the highest box office, the highest number of people and the total number of times in the summer file of China Film History. With the release of many films for the Lunar New Year, the industry is optimistic that the total box office of this year’s films will hit 55 billion yuan.

  "In 2023, the overall performance of the China film market was remarkable, and the market quickly recovered its vitality." In Zhang Tong’s view, many masterpieces have emerged during the Spring Festival, summer vacation, National Day and other holiday periods, and new audiences continue to enter the market. "This year’s head films generally have a strong family viewing attribute, and the proportion of older audiences has increased compared with previous years."

  This year, there are 81 movies in the Lunar New Year, which is not surprising to some people in the industry. In 2019, there are also 70 movies in the Lunar New Year. The staff of Daguangming Cinema said: "This year’s Lunar New Year’s files have diverse styles and themes to meet the needs of audiences of different ages." Ma Ye, president of Baiying (Beijing) Cinema Management Co., Ltd., believes that this year is the year with the most and most lively New Year movies.

  However, at present, Across the Furious Sea, which was released on November 25th, is still the leading movie at the box office, with a cumulative box office of 546 million yuan. Compared with this year’s Spring Festival movie "Man Jiang Hong" and "Wandering Earth 2", and the summer movie "Put all your eggs in one basket", "Disappeared She" and "Goddess the First Part", there is still a lack of "head movies" with strong box office, topics and reputation.

  "Up to now, this year’s Lunar New Year file has indeed not seen a large-scale film to incite the market to watch movies." Zhang Tong said that the highlight is the films released at the end of the year. Apart from Twinkle, Twinkle, Twinkle, Bright Stars, two Hong Kong films, Goldfinger, Sneak, and the workplace satirical comedy The Annual Meeting can’t stop! ",New Year’s classic IP" If You Are the One 3 "are all worth looking forward to. The staff of Daguangming Cinema also revealed that, according to the usual practice, "hot movies are basically released in the last two days of the year, and it is difficult to predict whether the annual box office can reach 55 billion yuan, but the overall momentum of the film market is good".

  Rui Cui, Liu Xiang and bid for the Olympic Games, directors of "Lost She" and "Put All Your Eggs", which achieved good box office results this summer, are all young directors who have not been well known by the public, and many films released recently have a good reputation. "The number of bad films has decreased this year, which is a good phenomenon." Wang Ce said that with the recent survival of the fittest in the industry, what remains is a relatively mature professional force. In his view, the current audience has "changed a batch" compared with a few years ago, the attraction of big-name directors and famous actors has declined, and the audience pays more attention to themes and stories. For creators, it is necessary to think about why the audience comes to see and create more viewing motives for the audience; On the other hand, the audience is also diverted, and the market is more subdivided. Different types of films such as suspense, science fiction and pure love have their own audience groups. Focusing on a niche type can also have a good market return. "The establishment of the film industrialization system is not only aimed at technology, special effects and service, but also includes R&D planning, script creation, process management, etc. In the past, screenwriters could create with their heads closed, and now they may have to consider the market more. When the entire large industrial system is perfect, no link can be built behind closed doors. "

  People in the industry generally have confidence in the China film market next year. "Next year, a large number of domestic films with rich and diverse types will be reserved." Wang Ce revealed that at present, the film industry has maintained a good development momentum, and the audience need not worry about the "film shortage" next year. Next, films such as Mr. Red Carpet will be shown in the Spring Festival, and a large number of films such as "Feng Shen II" are expected to meet the audience next year.

  Ritual sense attracts young people?

  Movies have social attributes. Watching movies on special holidays is a cost-effective entertainment consumption for young audiences.

  Recently, the movie "Twinkle, Twinkle, Twinkle, Bright Stars" has attracted the attention of people in the industry and the public: the director is a newcomer, the actor is not a flow star, and the theme is the fantasy love of the minority. However, the pre-sale box office exceeded 100 million yuan 23 days before the release, making it the earliest pre-sale movie and the fastest pre-sale movie for the New Year.

  "In my impression, the Lunar New Year files and movies are all family fun types." Hu Youqi found that there are many suspense and crime themes in recent Lunar New Year movies, as well as Goodbye, Li Ke Le and Dog God with pet themes. In the past, the typical Lunar New Year movies only had the traditional blockbuster Neptune 2: The Lost Kingdom and the established IP If You Are the One 3. According to the data from Taobao Film, there are more than 100,000 movies "wanted to see", among which "plot crime" accounts for 3 movies.

  "Suspense movies are a niche theme for the industry and the audience. These films have a small investment and a low box office ceiling, and usually choose a small schedule or a cold schedule." Wang Ce believes that although there are suspense films such as "Disappeared She" and "Put All Your Eggs on One Egg" exploding in the market this year, they rely more on the topic heat and are unrepeatable. "In the future, suspense films may not become a popular theme, but at present, as a mature market type and insurance investment theme, it may form a fixed output ratio in the domestic film market."

  In the eyes of the industry, with the renewal of movie audiences, young moviegoers are more willing to choose niche and personalized themes. The change of the New Year’s Eve schedule also makes more movies with rich themes and relatively small investment willing to choose this schedule. "Judging from the distribution of the schedule and its impact on the whole year’s market, the Lunar New Year file is expected to continue the heat at the end of the year until the beginning of next year before the Spring Festival file next year, which will play an important role in preheating and undertaking the Spring Festival file next year." Zhang Tong said.

  In addition to the quality of the film, the film side has also begun to exert its strength in marketing and distribution, enriching the movie-watching experience of fans. "Twinkle, twinkle, twinkle, bright stars" released on December 30, 1314 cinemas across the country will hold "snow field" activities at 13: 14 on the same day, which is considered by the industry as an important reason for the film’s pre-sale box office to outshine others. According to the data of Cat’s Eye Professional Edition, among the users who buy pre-sale tickets for "Twinkle, Twinkle and Bright Stars", the population under 25 is over 80%. On social media, many viewers who bought advance tickets showed their ticket purchase records, expecting the movie to "snow" when it was released.

  "As a kind of entertainment consumption content, movies not only have commodity attributes, but also have social attributes. Young audiences are the main consumers of social activities. They are more active and pay more attention to the sense of ceremony. On some special holidays, watching movies is a cost-effective entertainment consumption for young audiences. " Zhang Tong said.

  In order to create such a sense of ceremony, many cinemas have made innovations. Located on the first floor of Jing ‘an MOHO, Baiying Sanke Yinghua is a compound space combining a cinema and a restaurant. Ma Ye introduced that this year’s summer file was very busy during the National Day holiday, and the film market was relatively weak in November. Everyone took the opportunity to thoroughly clean the interior and carpets of the cinema, and carried out equipment maintenance, maintenance and staff training, so as to welcome the movie-watching craze with a better look after the opening of the Lunar New Year file.

  Bai Ying San Ke Ying Hua also designed a series of activities to create a sense of ceremony. For example, on December 16, Shanghai ushered in a cooling down, and the cinema chose to hold the "Winter Night Jazz Trio" on the same day to attract the audience with movie music; From December 20th to 25th, the stamp-stamping activity sought after by young people was introduced. With the ticket stubs exchanged for stamp-collecting cards on that day, the stamps of Wonka, Aquaman 2 and Detective Conan were hidden in the cinema space for the audience to find and stamp, and there would be staff dressed as NPC (non-player role) to interact with the audience. "We left these activities to create a sense of theater ceremony to young employees to plan independently, to attract the audience to stay in the theater for a while and leave an impression outside the film. When the audience has memories and emotional connections with the cinema, it is difficult for them to leave. "

Harden completely missed the Clippers, and Ballmer decided to give up the deal and pack George Mann for a new core.

According to a number of experienced NBA trading experts and reporters in Los Angeles, Clippers owner Ballmer has completely given up Harden. He has clearly told the rest of the management that the team will not be obsessed with chasing him. On the one hand, he does not want to see Harden put pressure on himself in renewing his contract, and on the other hand, he seems to change his mind and stay in Philadelphia, and then send out the plan after Philadelphia and the new team discuss the deal.

There is no doubt that the beard can’t be sent away by Philadelphia, and his agent has begun to push him back to the team training and make sure that Philadelphia will find a new team for him at this time. The Clippers are unwilling to bear the pressure of renewing their contracts, and they must definitely disconnect from George Cam, which is very clear to Deng Ge’s agent.

After completely missing James Harden, the Los Angeles Clippers will have to look for a new All-Star player. Judging from the suggestion report of some directors, it seems that everyone has an idea about Zion, and if he really gets him, the contract renewal problem of Cam can be solved, matching his annual salary of more than 50 million and adding Pang Hu to build a dual-core, which is absolutely strong. The league has stipulated a new policy and there should be restrictions on the rotation. Therefore, Tyrone has to be limited.

If you want to get him, the team is expected to send Paul George Gammann or Powell, and analyze the matching of transaction value and maintaining the fighting force lineup. I estimate that Ballmer will also ask for CJ mccollum. If so, it is enough for the team to send them both, plus the draft pick, Powell and Covington. If you want alvarado, you can also send a round and add some cash.

The Clippers have created a starting combination of Wei Shao, CJ mccollum, Zion, Leonard and Zubac, and with the assistance of batum and others, they definitely have a chance to enter the top four in the West. If there are no injuries, I think this combination can go further. Of course, it is important to improve the reserve strength.

After George and others go to Pelican, they will face the problem of renewing their contracts. Pelican can take this opportunity to ask for as many first rounds as possible in this transaction, and Clippers can also give them. Of course, the most important thing is that with Mann, the team can still guarantee its combat power in the future. Hylander is a good player, and the Pelican can take it. In the final analysis, if you want to ask for the opponent’s draft pick and young players as much as possible, your own young cornerstones will not work. If you can, I think it is king to exchange Varanciunas for the opponent’s Zubac.

On the whole, this trading scheme is very good. Pelican can solve the problem and meet the Clippers’ challenge. However, I think both teams need to hire coaches who can arrange defense reasonably now. The Clippers have many players who can defend, but they just can’t do it well. Telunlu has not changed this problem for so many years. If Pelican defends well, it won’t matter.

Harden’s situation is more complicated, so we don’t have to pay attention to it all the time. He will not be traded for a while, and the Clippers are not willing to spend more with him. Let’s look forward to the development of each team after the start of the season!

200 million euros! It was revealed that Manchester United wanted to sign Mbappé against Harland, and Real Madrid+Guardiola panicked.

Mbappé is still the focus of international football, and this French star will be the target of many giants in the transfer market this summer. However, according to the latest report quoted by Daily Goal and Daily Express, Manchester United, the premier league giant, is eyeing Mbappé and eager to bring in the French star worth 180 million euros, but seriously, without 200 million euros, it is impossible to complete such a deal of the century. Manchester United’s competitor is still Real Madrid, and of course the two giants have to compete with Paris, because the French giants will not be willing to let go of a world-class striker like Mbappé easily.

After Manchester United released Cristiano Ronaldo, Rachford became the first thigh of the team’s front line. This season, Rachford scored 29 goals, which was very good. However, Manchester United needs a stronger striker to help the team regain its glory. Considering that Manchester City has Harland and Manchester United signed Mbappé, it is the best answer. In this case, Manchester United’s lineup can compete with Manchester City. At least in the front line, the two teams will be equal. Similarly, Manchester United.

In the eyes of Paris, they still don’t want to let Mbappé go. After all, it is difficult for Messi to renew his contract with the club. If Mbappé is lost again, the striker line in Paris will be devastated. However, in the transfer market, the bitter melon is not sweet, and Paris has forced Mbappé to stay for many times. If the French star wants to leave, but Paris deliberately sets obstacles, the two sides will be torn, and then it will be difficult to end.

Manchester United hope to sign Mbappé with a large sum of money. Considering that the player’s actual value is already 180 million euros, if the Premier League giants want to succeed, they need to prepare a transfer fee of at least 200 million euros. British media revealed that Saudi local tyrants are preparing to spend 6 billion pounds to buy Manchester United. If the deal is completed, then the Red Devils will not be short of money, and it is really promising to complete the deal in Mbappé.

However, in the transfer market, Manchester United also has a strong rival, that is Real Madrid. In the Champions League, Real Madrid was swept by Manchester City, which made florentino realize that the team can’t continue to live on its laurels. Although Benzema is still strong, it is not at its peak. It is imperative to sign Mbappé, so Real Madrid will also join the competition.

The advantage of Manchester United is that they have a good relationship with Paris. As for Real Madrid, La Liga giants have tried to poach Mbappé many times, which makes Nasser very disgusted. Therefore, the possibility of Manchester United fishermen benefiting is not ruled out.

Essential for runners: the secret of preventing cramps in marathon.

Cramp is a sudden muscle pain, which is usually caused by muscle fatigue, dehydration, electrolyte imbalance and other factors. Here are some suggestions to prevent cramps:

Well-trained: Before taking part in the marathon, you should be fully trained and prepared to enhance your muscle strength and endurance and avoid muscle fatigue.

Proper warm-up: Carry out proper warm-up exercises before the competition, including easy stretching and jogging, to help muscles gradually adapt to the intensity of exercise.

Replenish water: It takes a lot of water to participate in a long marathon. Replenishing water in time can prevent dehydration and electrolyte imbalance, thus avoiding cramps.

Replenish electrolyte: electrolyte is an important component to help muscles contract and relax normally. Before, during and after the competition, properly supplementing electrolytes (such as calcium, magnesium, potassium, etc.) can prevent cramps.

Pay attention to rest: long-term exercise makes muscles tired and needs proper rest to recover. During the competition, if you feel muscle fatigue or discomfort, you should rest or slow down properly to avoid cramps.

In a word, the key to avoid cramps is adequate preparation, proper warm-up, supplementing water and electrolyte, and paying attention to rest, so as to help muscles adapt to exercise intensity and reduce the occurrence of fatigue and injury.
