　　CCTV News:In today’s May Day special program, we are going to meet a national model worker, Wang Wenshui. He is an ordinary farmer. With his courage and boldness, he has created the history of localization and large-scale planting of American ginseng. He is a Communist party member, leading his fellow villagers to the road of poverty alleviation and common prosperity. Today, 64-year-old Wang Wenshui is still running in the fields, studying the cultivation techniques of American ginseng.

　　The latest cultivation of new American ginseng varieties by busy field management

　　Near the May Day holiday, it is the time for American ginseng to emerge. Wang Wenshui rushed to the ginseng field early in the morning to fight drugs and weed with the workers and busy with field management. This is his latest American ginseng variety. However, a few years ago, American ginseng could not be planted in this land.

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:American ginseng itself has a kind of fungus. After we harvest American ginseng, some broken roots rot in the ground, which causes soil pollution. If you replant American ginseng, it will easily rot, and you can’t replant it for 15 to 20 years.

　　Kouzili Village is the birthplace of Wendeng American ginseng, and almost all the farmland in the village has been planted with American ginseng. Because the soil can’t be recycled, villagers have to go out and rent a new piece of land after harvesting ginseng every four years. This has become one of the biggest bottlenecks restricting the development of local American ginseng. Be sure to improve the soil! With such a goal, Wang Wenshui started round after round of experiments.

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:The 5 cm soil layer on the surface has good air permeability, and this bacterium is active quickly. So we turn this soil layer on the ground to the ground, to a depth of more than one meter, and suffocate this bacteria. At the beginning, I used shovels to shovel the land, and it took more than ten days to turn over an acre of land. In the later period, we had mechanization, and large-scale trucks could turn over more than two acres a day, which was very fast.

　　After 10 years of long exploration, this rural "soil expert" with little knowledge has solved the planting problem that has plagued local people for decades. This year, the planting method of deep ploughing has been applied to more than 100 acres of land.

　　Starting from 11 seeds, laying the industrial foundation of Wendeng American ginseng

　　After dealing with American ginseng for more than 40 years, Wang Wenshui’s passion has not been diminished by the passage of time. In that year, he started from 11 seeds and achieved today’s tens of billions of industries. In 1979, 22-year-old Wang Wenshui ended his four-year military career and returned to his hometown. By chance, Shandong Medicinal Materials Company handed 11 seeds of American ginseng to Wang Jizhen, Wang Wenshui’s father-in-law, for them to try planting. I didn’t expect this "foreign seed" to be "acclimatized".

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:There are a lot of planting difficulties, really a lot, and the transportation and communication are all very backward. Blindly, look at the symptoms with a magnifying glass and a microscope, and compare the books of crops. That’s it. Many things are repeated experiments step by step.

　　In order to record the growth environment and emergence of American ginseng in detail, Wang Wenshui and his father-in-law moved into a deserted mountain forest and recorded the light, temperature and humidity every two hours … … Finally, a month later, 11 seeds sprouted 8 seedlings. It was these eight seedlings that laid the foundation for the development of the whole Wendeng American ginseng industry in the future. Kouzi Licun was the only successful pilot among the nine American ginseng planting sites in Shandong Province at that time. However, just because the planting area on the mountain was too small, Wang Wenshui wanted to move American ginseng into the field below the mountain to plant it. Unexpectedly, the first farmland trial planting failed. After repeated experiments and comparisons, it was found that it was the soil.

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:We began to test and compare the soil of each plot, and finally we found out that there is a kind of resource on our mountain. Its book is called phosphorus-containing weathered soil, so we dug it out on the mountain and pushed it to our farmland one by one to improve the soil.

　　More than 40 years have passed, and the young veterans of that year are now full of white hair. At the beginning, the eight seedlings have now become a planting scale of 55,000 mu and an annual output of more than 7,500 tons. In the American ginseng market in China, 6 out of every 10 American ginseng come from Wendeng.

　　Work tirelessly to lead the whole town to get rich together.

　　"Living a good life with the big guys" is Wang Wenshui’s greatest wish. On the road to rural revitalization, he led the villagers to take off their "poor hats" and sow more and more "golden seeds" in the fields of hope. In the 1980s, it cost about 2,000 yuan to buy a catty of American ginseng seeds, which was enough to build a house. It takes 1.5 kg of seeds to plant one part of American ginseng. Such a large capital investment is unacceptable to ordinary villagers.

　　Tian Mingguo, a villager from Dongquan Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:At that time, I was worried when I was asked to plant it. I was also afraid of losing it. Secretary Wang said, Ming Guo, there is nothing for you to plant. If you lose it, I will bear it with you. The first harvest was good, and it sold for nearly 300 thousand yuan.

　　In the ginseng field of Zhangjiachan Town, Wang Wenshui can often be seen. Which one encounters planting problems and which one will not build a ginseng pond, Wang Wenshui went door-to-door to guide. Wang Wenshui also wrote the experience of seed ginseng for many years into a manuscript of seed ginseng records, and donated it unreservedly to the medicinal materials station of Wendeng District Agricultural Bureau for vigorous promotion.

　　Wang Wenshui’s youngest daughter Wang Lin:When I was young, when I was eating at home, farmers came to dig up a diseased leaf of American ginseng and show it to my father. No matter whether my father ate the first bite or the last bite in the bowl, he always put down his chopsticks, read them first, and then finish the rest. Sometimes a meal may come to several people, and he may have to eat it several times before he can finish it.

　　With the growing planting area of ordinary people, how can we make money without letting everyone suffer the crime of "facing the loess and facing the sky"? Wang Wenshui took out the energy of trying to plant American ginseng and began to study all kinds of planting machinery.

　　Wang Wenshui, secretary of the Party branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province: This machine I developed is called American ginseng fertilizer spreader. I am going to study these three hoppers to hold particles, trace elements and organic fertilizer. These three hoppers flow in the ground at the same time, so that the rotary plow can rotate in the ground, which is uniform, labor-saving, labor-saving and fast.

　　In addition to the fertilizer spreader, Wang Wenshui has also developed a variety of special machinery for American ginseng, such as ridging machine, ginseng washing machine and beard removing machine.

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:I always feel that I am still a Communist party member, and I have benefited from my own cultivation. Why can’t I be rich by myself? I have to bring all the people in the village to be rich, so that I can be happy and feel at ease … …

　　Today, in Wendeng, more than 3,000 farmers have planted American ginseng, and tens of thousands of employees have changed their lives and embarked on the road of getting rich by relying on American ginseng. Wendeng American ginseng has also grown from the earliest simple cultivation to more than 20 deep processing enterprises, and the added value of the industry has increased by more than 50%. Now Kouzili Village is ecologically livable and prosperous, and the appearance of the village has been greatly improved. During the May Day period, Wang Wenshui will also speed up preparations for the American ginseng deep processing workshop to be put into use in June.

　　Wang Wenshui, Secretary of the Party Branch of Kouzili Village, Zhangjiachan Town, Wendeng District, Weihai City, Shandong Province:To be an industry, I think it is worthwhile for people to do one thing well in this life. My goal is to "push the car without falling down". As long as I have a breath, I will continue to fight for American ginseng.

　　Cctv newsA MV-22 Osprey transport plane of the US military crashed into the sea in the waters near Australia, and 23 people were rescued. Three people were declared dead after missing. In Okinawa, where the "Osprey" often flies overhead in Japan, this news has increased the anxiety and opposition of the local people.

Okinawa local people marched.

　　On the 8th, Esaki Tetsuma, Japan’s new Minister for Okinawa and Northern Territory Affairs, said in a rare way that the Japan-US Status Agreement, which stipulated the legal status of US troops stationed in Japan, "must be slightly revised".

　　At the press conference, Jiang Qi stressed, "Even if it takes more time, the government should fully understand the feelings of Okinawa residents. What it should say to the United States should be said."

　　However, as for the Japan-US Status Agreement, he said that "I am a layman" and did not talk about the specific direction of revision.

　　Japan and the United States signed the "Japan-US Status Agreement" in 1960, which stipulated that when civilian and military personnel employed in the US military base in Japan caused accidents or committed crimes while performing official duties, the US military stationed in Japan enjoyed priority jurisdiction, which was essentially equivalent to giving this group judicial immunity.

　　Whenever US military personnel commit crimes in Okinawa or an accident occurs in US military aircraft, the Japanese people’s call for amending the Japan-US Status Agreement is even louder.

　　However, under the pressure of the United States, the Japanese government has been holding a negative attitude towards amending the Japan-US Status Agreement for many years.

　　As the newly appointed Minister of Okinawa Affairs in the cabinet reshuffle on the 3rd of this month, Jiang Qi offered to amend the Japan-US Status Agreement, which was even called "rare" by the Japanese media. However, it is not clear whether Jiang Qi’s statement reflects the overall policy of Abe’s government.

　　However, an Osprey still took off and landed from the Futenma base in Okinawa on the 7th — — The Japanese media believe that the US military has demonstrated the de facto "refusal posture".

　　On the 8th, Nicholson, the highest commander of the US military stationed in Okinawa, even told Tomokawa Shengwu, the deputy governor of Okinawa Prefecture, who came to protest, "‘ Osprey ’ Flying around the world is the policy of the US military, which explicitly rejected the Japanese request for grounding.

Symptoms of generator belt being too tight and too loose

Too tight: 1. The belt is stuck and needs more horsepower to turn; 2. It will lead to large radial load of motor shaft and easy fatigue; 3, affecting the service life of the belt; 4. It is easy to damage the engine bearing.

Too loose: 1. Slipping phenomenon and abnormal sound; 2. The premature wear of belt will affect the service life of belt; 3, resulting in insufficient charging of the battery by the engine, affecting the service life of the battery; 4. Engine jitter, insufficient power, high fuel consumption and high water temperature may occur.

Precursor of generator belt replacement

1. When the generator belt is running and sent out.

This is because the engine belt is too loose or the installation position is uncertain. If there is sliding noise, it is best to check it in time.

2. The generator belt is cracked, cracked and peeled off.

This is because the installation position is wrong, the stress is uneven or corroded, or because the engine belt has been used for too long and aged and hardened.

3. When the service life of the generator belt is nearly 2 years, or when driving 60,000 kilometers.

Generally, the service life of engine belt is 2 years or 60,000 kilometers. If it exceeds the specified service life, it needs to be replaced. Never wait until it is broken before replacing it. It is easy to be in danger.

What happens when the generator belt breaks?

If the generator belt breaks when the car is running, the car may lose power instantly. If the safety distance of the vehicles behind is insufficient, traffic accidents will easily occur, especially on the expressway.

Therefore, it is necessary to regularly check the engine belt, generator belt, water pump belt, air conditioning compressor belt, timing belt and other parts of the car to ensure that all parts of the car work in good working condition.

　　In less than four years, from "returning to the market value of 100 billion" to "don’t be ST", investors’ confidence and expectations for Yonghui Supermarket (601933.SH), a former white horse, are constantly lowering.　

　　"A dime for a year", "A hundred-year loom" and "Fujian will lose forever", Yonghui Supermarket investors expressed their helplessness in the stock bar. The company’s current market value is higher than 100 billion in 2020, and it has been halved.　

　　At the same time, there is also performance under pressure. According to the latest performance forecast, in 2021 and 2022, Yonghui Supermarket may have a total loss of about 6.6 billion yuan.　

　　In recent years, Yonghui Supermarket has also taken a number of measures to turn the situation around, including repeated buybacks in the stock market and the introduction of JD.COM veterans in the management. Judging from the effect, the effect of stimulating stock prices and improving performance is not obvious.　

　　How to get to Yonghui Supermarket in the future? Can the company promise to make a profit in 2023? This is a problem that many investors are paying attention to now.　

　　The market value dropped from 100 billion to 30 billion.　

　　Looking back at the market value performance of Yonghui Supermarket in the last four years, it can be described as peaks and valleys.

　　Judging from the stock price trend, at the beginning of 2020, Yonghui Supermarket’s share price was still around 7 yuan, and it went down all the way after reaching the stage peak of 11.2 yuan in April. As of the close of February 9, 2023, the total market value of the company was only 32.3 billion yuan.　

　　In order to stabilize the stock price and give investors confidence, Yonghui Supermarket started a big repurchase when the market value continued to decline.　

　　In October 2020, Yonghui Supermarket issued a repurchase plan, indicating that it intends to repurchase the company’s shares with its own funds of no more than 2.7 billion yuan. By May 2021, the company had actually repurchased 390 million shares, accounting for 4.13% of the total share capital, and the total amount of funds used was 2.7 billion yuan, which was cancelled in September of the same year.　

　　In August, 2022, Yonghui Supermarket issued a repurchase plan again, and planned to repurchase no more than 150 million shares with its own funds of 400 million to 700 million yuan. As of January 30, 2023, the company has repurchased 95.64 million shares, and the total amount of funds paid is about 298 million yuan.　

　　At the same time, the executives of Yonghui Supermarket are also increasing their shares. From February 2021 to November 2021, Zhang Xuansong, the chairman of the company, and his concerted action, Xishirun Herun Series Fund, increased their holdings by 184 million shares, accounting for 2.03% of the company’s total share capital.　

　　Wu Lefeng, secretary of the board of directors of Yonghui Supermarket, also increased his holding of 68,800 shares in May 2022, accounting for 0.00076% of the total share capital. According to the average price of 4.36 yuan/share, the total amount of funds spent is about 300,000 yuan. According to the 2021 annual report, Wu Lefeng earned an annual salary of 660,000 yuan. According to the current share price, if Wu Lefeng still holds it, the book floating loss will exceed 18%.　

　　However, while Zhang Xuansong and concerted action increased their holdings, their personal shareholding ratio was decreasing. According to the financial report, in the third quarter of 2020 -2022, Zhang Xuansong’s personal shareholding ratio has dropped from 14.79% to 9.72%, with a cumulative reduction of more than 500 million shares. By the third quarter of 2022, 355 million shares of Zhang Xuansong were pledged, accounting for 40% of the shareholding ratio.　

　　Huge performance losses, tight capital chain　

　　The market value of Yonghui Supermarket continues to fall, which is not unrelated to its declining performance.　

　　Yonghui Supermarket was listed at the end of 2010. By 2019, the company’s revenue has increased to 84.9 billion yuan with an annual growth rate of 15%-24%. However, since 2020, the company’s revenue growth rate began to decline. From 2020 to the third quarter of 2022, this indicator dropped from 9.8% to 1.53%, and the positive growth of 1.53% was achieved on the negative growth base in 2021.　

　　The performance of net profit is also not optimistic. According to the performance forecast, Yonghui Supermarket is expected to lose 2.7 billion yuan in 2022, which is smaller than the loss of 3.9 billion yuan in 2021, but the loss is still huge.　

　　Regarding the reasons for the loss, Yonghui Supermarket said in the performance forecast that first, due to the COVID-19 epidemic, more stores were closed; Second, the transaction price of the company’s financial assets in the secondary market dropped significantly in 2022, and the annual loss of fair value change was 640 million yuan; Third, the company invested about 700 million yuan in science and technology throughout the year, and the online business sales lost 440 million yuan.　

　　The financial assets of Yonghui Supermarket are mainly equity investments such as Karman Topco L.P and Arowana.　

　　In the third quarter of 2022, Yonghui Supermarket sold its shares in Arowana, with a loss of 115 million yuan (before tax); So far, the cumulative investment income of Arowana investment target is 173 million yuan (before tax).　

　　As for Karman Topco L.P., according to the 2022 performance forecast, the fair value of Karman Top Co L.P decreased by 524 million yuan compared with the beginning of the year. The company conducts impairment test on some long-term assets and makes provision for impairment. According to preliminary calculation, the company is expected to accrue long-term equity investment and other long-term assets impairment of about 600 million yuan.　

　　On the whole, however, most of the company’s losses in 2022 were caused by the epidemic and poor investment in financial assets. Although the online business suffered losses, it lost 400 million yuan compared with the previous year, and its sales increased by 21% year-on-year. The company’s operating fundamentals are improving. Li Songfeng, CEO of the company who has been in office for less than two years, has also said that he will strive to achieve profitability in 2023.　

　　According to the information, Li Songfeng joined Yonghui Supermarket in 2021 and was hired by the company with a high salary. According to the 2021 annual report, his annual salary was 3.96 million yuan, much higher than other senior managers.　

　　According to the announcement, Li Songfeng was deeply involved in the transformation of JD.COM’s mobile Internet, the construction of China and Taiwan, and the external empowerment of technology. He was selected into the JD.COM JD Pilot Future Leader Program and has 20 years of technical and management experience. After joining the company, Li Songfeng will be responsible for the technology strategy and digital transformation strategy of Yonghui Supermarket.　

　　Li Songfeng’s profound experience in the field of interconnection technology is his confidence in calling for profitability in 2023. But judging from other financial indicators of the company, profit is not only a slogan, but also an imminent pressure.　

　　In the third quarter of 2022, the asset-liability ratio of Yonghui Supermarket reached 84%, and the monetary fund in its account was 8.1 billion yuan, while the short-term loans, accounts payable and non-current liabilities due within one year during the period totaled 18.1 billion yuan, which is far from being covered by the company’s current monetary fund. If it fails to make profits, the company may face greater pressure and risks in the capital chain.　

　　Tik Tok’s US delegations joined the melee strongly.　

　　Yonghui Supermarket suffered losses in 2021, which was related to the large-scale expansion of online supermarkets and community group purchases, including Meituan Youxuan, Dingdong Shopping, Pupu Supermarket, Duoduo Shopping, Orange Heart Youxuan, Tik Tok Mall, etc. The low-price strategy of such retail channels had a great impact on the operation of traditional supermarkets.　

　　According to the research data of soochow securities, the fresh products of community group buying platform are 25%~30% cheaper than supermarkets on average, and the standard daily necessities are about 20% cheaper on average. The common people are very sensitive to the price of daily consumer goods. Such a large price gap reduces the flow of people in supermarkets and puts pressure on retail prices.　

　　In addition to the price advantage, the market share of traditional supermarkets is gradually being eroded.　

　　According to the China Instant Retail Development Report 2022 released by China Chain Store & Franchise Association in November last year, more than 90% of users prefer to spend online to meet their daily needs.　

　　The report also mentioned that people in the industry generally predict that the compound growth rate of the instant retail market will be around 50% in the next few years. It is estimated that by the end of 2026, the relevant market size of the instant retail industry will exceed 1 trillion yuan.　

　　As a traditional retailer, super leader. The current performance of Yonghui Supermarket also reflects the plight of traditional supermarkets. In recent years, news about the closure and declining performance of traditional supermarkets such as Carrefour, Wal-Mart and RT Mart has frequently appeared in the media.　

　　Based on market changes, in order to get rid of this situation, shortly after Li Songfeng took office, Yonghui Supermarket put forward the goal of building an omni-channel digital retail platform based on fresh food and taking customers as the center in 2021, and upgraded its organizational structure to be more flat, flexible and young, which is also its new ten-year strategy for the future.　

　　Judging from the performance of the online channel of the 2022 annual performance forecast, the strategy of "Science and Technology Yonghui" has achieved results, but compared with other platforms, there is still much room for improvement.　

　　For example, in terms of service, in July, 2021, Yonghui Supermarket WeChat applet "YH Yonghui life+"illegally charged 1 yuan packaging fees without the consent of consumers, and its affiliated companies were fined by Shanghai State Administration for Market Regulation for a total of 40,000 yuan, which quickly reached the top of the hot search and triggered discussion.　

　　In August of the same year, Yonghui Supermarket issued an apology statement, saying that it attached great importance to the issue of "1 yuan packaging fee charged by Yonghui Life applet", saying that it had urgently optimized the commodity packaging service and charging rules. After rectification, the online platform of Yonghui Supermarket has been changed to be charged, that is, the order can only be placed successfully after 1 yuan’s fee has been paid. In terms of delivery timeliness, Yonghui Supermarket takes one hour.　

　　Based on these two items, online platforms such as Meituan Shopping, Dingdong Shopping and Pupu do not charge packaging fees. In addition, in terms of delivery timeliness, these platforms take half an hour.　

　　According to iResearch’s Research Report on User Insight of C-End Platform in the Same City, 62.8% of users can accept the delivery time within 30 minutes to 50 minutes, and more than 18% of users hope to receive the goods within 30 minutes of placing an order. It has become an important label on instant retailing.　

　　In this respect, Yonghui Supermarket is still a long way from users’ hopes. In order to win the online battle, Li Songfeng still faces one huge challenge after another. (Jordan) (produced by Thinking Finance)

　　Original title: Is Esther Yu scolded like this in South Korea? Hanwang: Can this ordinary girl be popular?

　　Author: Xia Dada

　　Good afternoon, students ~

　　Have you seen Esther Yu and Vin’s new play A Little Forest for Two recently? Many netizens said that they would be sweetened by Esther Yu!

　　Professor Gao Leng × Fashion Little online celebrity’s setting is earthy and sweet, which seems to be easy to decompress, and the sugar content of the two people is particularly excessive when interacting!

　　I have to say, Esther Yu really killed the male killer, and this time the modeling in the play is also very eye-catching.

　　Plus just finished freesia tactic, Esther Yu recently but harvested a lot of affection!

　　But later, as soon as I went online, I found that many netizens spit out Esther Yu’s "ordinary girl", her voice was ugly, and she was not suitable for being a big woman.

　　But one thing, I personally like Esther Yu’s lovely looks next door. She looks comfortable and has no sense of distance, just like a little sweetheart ~

　　So what if the appearance is not exquisite enough? It doesn’t hinder becoming a male god harvester at all!

　　Speaking of which, in fact, Seven is also like this, and its appearance is not outstanding, but Haoran Liu, Song Weilong and Allen who have worked together … no matter how old they are, they have a sense of cp in the same box!

　　Andy, too, from Li Xian to Cheng Yi, which one was not knocked on by everyone?

　　The question is, their face value is not very top-notch in the entertainment circle, but why can they hold the bg banner steady?

　　In fact, if you look closely, you will find that their looks have something in common, which is a very popular "pig looks" in the past two years.

　　At first glance, the "pig line" doesn’t look good, but in fact, as long as you find the right way to become beautiful, it can still be exquisite and beautiful!

　　Speaking of which, I thought that I wrote an issue of "Animal Department Appearance" to you last year, and many students said that they wanted to see the second issue, so let’s arrange "Animal Department Appearance 2.0" today!

　　You can take a look at the following content and see which one is more consistent with your appearance, so that you can overtake in the corner and become beautiful ~

　　First of all, let’s talk about the appearance of the pig line mentioned at the beginning. The facial bones of this appearance are not strong, and the face lines are very round.

　　Moreover, the appearance of the pig is generally short in the lower half of the face, with a low eye position and a full sense of youthfulness (who can see that Seven is already 30+? )

　　On the front, the nose is fleshy, and some of them are slightly turned out, just like the pig’s nose.

　　None of the above hardware seems to be superior? But in fact, with the overall appearance characteristics, it is the standard sweet girl face!

　　However, under these hardware, we have to find the right idea of beauty, in order to turn the seemingly earthy characteristics into exquisite and attractive ones ~

　　Because the pig line looks dull, if you want to strengthen the exquisiteness, you can create some [acute angles].

　　In the five senses, if there are some sharp and angular details, such as sharp corners of the eyes, corners of the mouth and chin, it can give people a delicate sense of detail.

　　Full face operation is not easy for makeup white, so I suggest you start with eyeliner, because eyeliner painting is really the most obvious place. Today I will teach you a very simple method:

　　▶1.用手指轻轻扯住眼尾，让眼线能更好的操作👇🏻

　　▶2.用眼线胶笔在眼尾轻轻拖出来，不用太长，就是个很粗糙的线👇🏻

　　▶3.再拿一把扁平的斜向刷，把线条拉出来👇🏻

　　▶4.想看起来更自然的话，可以用扁头刷沾取深色眼影，在眼线上方慢慢往前晕染👇🏻

　　脸平的猪系长相，可以靠加深山根的阴影来缩短眉间距，来打造明艳感。

　　①先找到眉峰，然后顺着肌肉走向画出眉尾。

　　②用棕色的染眉膏轻刷眉毛，注意：不要下太重手碰到眉毛底部的皮肤，不然会蹭出蜡笔小新眉！

　　主要轻轻带过眉毛让颜色更柔和即可，因为粗眉实在不适合深色，会显得愣👌

　　之后就是通过“C字形”的阴影去缩短眉间距，记得这个“C”的弧度尽量大一些，让山根的存在感更强。

　　④鼻子的侧影稍微带过就好，鼻头这里打一个圈，让鼻尖显得更翘，还能让五官显得更加集中～

　　猪系长相的眼妆，在眼影方面不是很重要，太浓的眼影显得很没有精神。

　　比起眼影，灵动的睫毛才是增加精致灵动的关键，看我扒到了虞书欣眼睫毛教程！

　　Her method is to match a fishtail hair with a fairy hair, using these three models of Anji Cat:

　　Stick a row of 12mm fishtails first, so we don’t have to stick them so closely, leaving a little space for fairy hair.

　　‍

　　After that, stick fairy hair in the gap, about 4 hairs are enough, which can naturally deepen the three-dimensional sense and naturally enlarge your eyes.

　　Finally, add lower eyelashes, and you can get360-degree three-dimensional big eyes without dead ends with 4 eyelashes ~

　　The appearance of the deer is also very hot in the past two years, and it is as smart and playful as the deer.

　　The most obvious feature of this appearance is that it has big clear eyes as round as a deer, and the lying silkworm is also obvious.

　　Deer girls’ faces have a stronger sense of outline, and their faces are thinner and longer, mostly oval faces, and their facial lines are also very smooth.

　　Because the deer is full of wild breath, if it is placed on the appearance of the deer, it is thick hair. Thick, black wild eyebrows have a lot of hair.

　　It’s like an elf coming out of the forest, smelling the grass in the forest ~

　　These natural advantages in hardware determine that the appearance of deer is not suitable for over-modification, and maintaining natural beauty is the right solution.

　　So, try to avoid heavy makeup and smoky makeup that cover the original fresh aura of deer.

　　We must give full play to the advantages of the deer’s appearance, and the center of gravity of the whole face is on the eyebrows with strong presence.

　　Deer’s eyes are round at first. Compared with fox’s eyes, they emphasize height rather than length. So we can increase the height of our eyes and make them more round by lying silkworm.

　　When drawing a lying silkworm, sink the center and fold the sides.

　　This will visually increase the height of the eyes and make them look round.

　　Lip color can be weakened, and using milk tea color and milk apricot lipstick to create a clear and wild feeling is much more natural than big red lips.

　　Because deer looks have their own forest temperament, a strong sense of hair is the key to creating a sense of atmosphere.

　　Compared with short hair, deer looks more suitable for long hair, and it is better to have black hair with a little curl.

　　Even if it is dyed, try to choose dark hair. Like dark brown, dark brown and dark coffee are all good colors, which can improve temperament.

　　Students with straight hair can use an air cushion comb before going out, and their hair will look much better.

　　Of course, curly hair is ok, but the curl doesn’t have to be at the same height, which will make you look carefully dressed.

　　The most natural thing is lazy curls. Here is a method that a disabled party must learn: tie your hair into three braids, on the left and right sides and above.

　　Roll the splint outward and inward, then loosen the curling iron, slide to the bottom and roll it all up. The latter two are the same.

　　If you want to say the cutest and most tender appearance, it must be the rabbit tie face of off the charts who kills men!

　　Rabbit is a classmate with looks, and his skin is as white and tender as a rabbit.

　　This appearance, facial features are small, round almond eyes are not very big, but very bright and smart ~

　　Their lower court is short, and what they generally have is a short chin+a small cherry mouth, as well as cheek meat with a slightly bulging jaw, which is exactly the same as that of a rabbit.

　　To say the most distinctive place, it should be a slight convex mouth. When you don’t laugh, two rabbit teeth are looming, and when you smile, it is very soft and cute ~

　　For students who have a slight convex mouth and are troubled by inner double and fleshy face, it is very suitable to master the idea of becoming beautiful in rabbit beauty.

　　At first glance, the appearance of rabbits will have a low stereoscopic degree and a lot of white space on their faces, but it is not suitable for fleshy faces if they are over-repaired.

　　Therefore, we can focus on creating a lying silkworm and a full risorius to neutralize the blank feeling of the face.

　　Lying silkworm mentioned above, so let’s focus on how risorius stands out.

　　When it comes to rabbits, everyone’s impression is pink and tender, and the overall tone of the rabbit makeup is mainly pink and orange.

　　To highlight risorius, use a high-gloss blush. Brightness is generally light-colored milk powder and purple. Low lightness is generally close to skin color, such as apricot orange, cinnamon, orange brown. ….

　　If you can’t tell the difference, you can adjust the photo to black and white mode, and the low brightness is obviously more gray.

　　High-brightness blush is swept horizontally in the face, so pay attention to the range.

　　You can also try to dip in the warm brown tone to repair the capacity, draw a horizontal line from the base of the nose to the cheek, and then smudge it.

　　You can also try dipping it so that risorius can lift it visually, and the whole person looks even younger.

　　You can also try today’s animal face 2.0 dry goods. Have you found out which type you are?

How is your pure electric car experience in the cold winter?

The discount on battery life may not be the worst thing. Recently, more than a dozen Tesla owners in Canada have reported that even the air conditioner can’t be used in winter. Not only is the car frozen at a discount, but people are also frozen with a snot and tears.

Moreover, the basic things that can’t be heated in winter are heat pump air conditioners.

This is very strange. The high-efficiency and energy-saving advantages of heat pump air conditioners have not been brought into play, but they cannot be heated, which has attracted the doubts of some Canadian car owners and attracted the attention of Tesla’s R&D team. Musk said that this is a high priority for Tesla.

But even weirder, Musk said that the failure of heat pump air conditioner turned out to be a software problem, which can be completed by firmware update. Perhaps many people have never heard of it, and air conditioners still need OTA. However, after understanding the structure and working principle of Tesla heat pump air conditioner, we can find that this set of hardware can realize 12 different functions, and all the functions are controlled by software.

Therefore, the problem of Tesla heat pump air conditioning may really be a software problem.

So, how amazing is Tesla’s heat pump air conditioner? Why can’t refrigeration occur under extremely cold conditions? Can the industry solve this problem? After reading the patent of Tesla heat pump air conditioner and having a conversation with the Weiling engineer of Midea, the car found the answer to the question.

This month, countries in the northern hemisphere ushered in the coldest time since winter, and electric vehicles also entered the worst stage of the year.

Recently, Tesla owners in Canada reported that they were driving in an extremely cold environment and the heat pump air conditioner could not be used.

Twitter user @TSelvig said that when traveling that day, the temperature had dropped to-40 C. In this extremely cold weather, when he was driving Tesla Model Y, the heat pump air conditioner could not be used. After trying to restart the vehicle and call Tesla customer service, this problem still cannot be solved, and the owner is a few hours’ drive from the nearest service center, so it is impossible to drive without air conditioning.

In the end, the family switched to a fuel car.

Another Model Y owner @paateach has a richer experience. His Model Y has no warm air for two consecutive winters.

He tweeted that he lived in Saskatchewan, southern Canada, and in February last year, he encountered the situation that the heat pump air conditioner could not be used, and there was no warm air for a whole month. Later, Tesla replaced a group of super manifolds for him, and the heat pump air conditioner could be used at that time. However, by this winter, when the temperature dropped to -30℃, he once again encountered the situation that the heat pump air conditioner could not be used.

At that time, he photographed the prompt on the car screen: the cockpit climate control system needs maintenance, and the heating and cooling systems will be restricted or unusable.

Two car owners questioned Tesla: Why did Tesla’s heat pump air conditioner fail in extremely cold weather? Tesla has been repaired several times, why is the maintenance plan still invalid?

Some car owners even said that after this winter, they hope to sell their Tesla in exchange for a fuel car, at least there will be no air conditioning and heating failure.

Angie Dean, chairman of Tesla Owner’s Club in Alberta, Canada, said: "In Alberta and Saskatchewan, Canada, more than a dozen Tesla owners have experienced the problem that heat pump air conditioners cannot be used."

Just last week, the owner community Drive Tesla Canada tweeted @ Musk, asking him to comment on the heat pump problem. Musk replied to the tweet within 5 minutes, saying that maintaining the heat pump air conditioner has a very high priority. After 40 minutes, Musk said that the new firmware of heat pump air conditioner has been introduced to users.

It is quite curious that why the failure of heat pump air conditioner can be repaired by firmware update? In addition, after the firmware update is completed, there is still feedback from the owner that heating cannot be done. Is the firmware update useful?

In a patent document published by Tesla in 2019, the structure and operation mode of the heat pump air conditioning system were demonstrated. At the beginning of 2020, with the mass production of Model Y, this patent was also transformed into the mass production application of Tesla.

If you open the front case of Tesla, you can see the heat pump air conditioner and many pipes and harnesses. In fact, this is just the tip of the iceberg of the heat pump system. From the patent drawing, Tesla’s heat pump air conditioner has 11 main components, and is responsible for the thermal cycle of the whole vehicle, which can lead to different parts of the vehicle such as cockpit, battery pack and motor.

These main components are compressor, cabin condenser, cabin evaporator, battery system cooling device, cabin blower, motor liquid-cooled condenser, storage battery, three-way compressor air outlet, low-voltage electric cabin heater (PTC), recirculating air conditioner and heating.

Among the 11 main components, Tesla did not directly cancel the traditional PTC heating, but still equipped with a low-voltage PTC heating. However, due to the lack of power, this PTC heating device can not directly heat the cabin, but provides auxiliary heating when the heat pump system is insufficient.

Surprisingly, Tesla’s hardware can realize 12 different working modes, which are completed by different software scheduling.

Among these 12 working modes, there are only three modes in which heat pump participates. Heat pump participation in heating can be divided into pure heat pump mode and mixed heating mode. When the heat pump efficiency is high, the pure heat pump mode is activated, and when the efficiency is low, the mixed heating mode is activated. The heat pump can be mixed with PTC heating and can also be added to the evaporator for heating together.

In addition, the cabin and battery system can be heated simply by using the compressor and evaporator. In addition, the in-vehicle thermal circulation system can also realize the functions of cabin defogging, defrosting, dehumidification and so on.

A conclusion can be drawn here: it is indeed feasible to fix the problem of heat pump air conditioning through firmware update.

When there is nothing wrong with the hardware of the heat pump air conditioning system, the adjustment of the heat pump air conditioning system can be realized by adjusting the software scheduling in different environments.

As far as the heat pump system is concerned, there is a strong relationship between the efficiency of heating the cabin and the efficiency of the heat pump. Because the working principle of heat pump air conditioning is to exchange heat energy inside and outside the car.

Through the evaporator, the refrigerant can absorb heat from the external environment, and after the refrigerant in the car is liquefied, it releases heat, so that it can heat the cabin.

However, if the temperature of the external environment is lower, it is more difficult for the refrigerant to obtain heat from the external environment, which leads to the low heating efficiency of heat pump air conditioning in extremely cold environment.

Tesla also knows this obvious problem, so it adds auxiliary heating devices in addition to heat pump air conditioning.

Tesla drew a chart in the patent, which can explain the efficiency of heat pump air conditioning at different temperatures. The efficiency coefficient of heat pump air conditioning is expressed by COP(Coefficient of Performance). When COP=1, it means that the consumed electric energy is equal to the generated heat energy. When COP>1, the heat pump air conditioner is in the high efficiency area, which means that it can get more heat energy by consuming less electric energy.

As can be seen from Tesla’s chart, when the ambient temperature and battery temperature are lower than -20℃ at the same time, the efficiency of heat pump air conditioning will be very low, which is also considered as extremely cold temperature by Tesla, and there is no solution below this temperature. But at this time, just heat the battery, the COP value will increase, and the heating system can be used normally.

When COP=1, the heat pump air conditioner does not work and relies on evaporation to achieve heating. When COP≥1, the heat pump air conditioner will participate in heating, and the temperature needs to be above -10℃.

The second conclusion can be drawn here: if the weather outside is extremely cold, even if the firmware of the heat pump air conditioner is updated, the heating effect will still be poor. The solution is to heat the battery, or preheat it before going out.

However, under the tweet that Musk replied to the updated firmware, there are still many users who feedback that the vehicle still cannot heat.

Then, there is probably a hardware problem.

Tesla owner @paateach said on Twitter that his Tesla Model Y has been replaced with two super manifolds, including the sensor of heat pump air conditioner, expansion valve and refrigerant pipeline. The heating system can be used temporarily, but I am very worried that it may be damaged again.

Twitter user Tesla owner revealed the research and development story of heat pump air conditioner online. Recently, Tesla’s engineers in California and Alaska are testing heat pump air conditioners. The test results show that Tesla’s heat pump air conditioners can work normally below -30℃ because the heat pump air conditioners have two refrigerant cycles.

At the same time, engineers also found the problem: in extremely cold weather, the cover plate of the front air inlet will be frozen and damaged, which will lead to the inhalation of cold air during driving. Because the cold air temperature is too low, the sensor will report an error to the system after sensing it. At this time, the compressor will stop working and the heating will stop.

In order to solve this problem quickly, Tesla may start the compressor by software, temporarily avoiding the heating failure in extremely cold weather. But to solve this problem completely, Tesla may need to update some hardware later.

For the automotive industry, heat pump air conditioning is still a new thing, and Tesla Model Y was mass-produced in early 2020. Prior to this, pure electric vehicles generally used PTC to heat the interior of the car. But even under ideal conditions, the COP of PTC is 1. Low efficiency leads to very large electricity consumption for PTC heating, which further becomes a major factor affecting the battery life of electric vehicles in winter.

The efficient performance of heat pump air conditioning has attracted the attention of electric vehicle companies. In 2021, all new pure electric vehicles were basically upgraded from PTC heating to heat pump air conditioning. However, due to the limitation of refrigerant, when the temperature is below -10℃, the efficiency of heat pump will be greatly reduced. At this time, it is necessary to rely on PTC heating to heat vehicles.

For example, Tucki P5 is equipped with a heat pump air conditioner to achieve efficient heating, but it is also equipped with PTC. When the temperature is lower than -10℃, the vehicle will start PTC heating to heat the interior.

It can be said that Tucki P5 has solved the shortcomings of heat pump air conditioning to some extent, but it has not been completely solved.

Weiling, another new auto parts manufacturer, has solved the heating problem in extremely cold weather. Speaking of Weiling, maybe many friends in the automobile circle are no strangers. Weiling is a subsidiary of Midea Group, a domestic appliance head enterprise.

Last year, several auto parts announced by Weiling included automotive heat pump air conditioners.

At present, R134a(CH2FCF3, tetrafluoroethane) is usually used as the refrigerant for heat pump air conditioning, but when the outside temperature is low, the heating capacity is obviously attenuated. Therefore, there are explorations of mixed refrigerants in the industry, but the performance cannot be significantly improved.

The engineers of Weiling parts found another way, using carbon dioxide as refrigerant, and the heating efficiency was obviously improved at extremely cold temperatures.

Weiling’s rotary CO2 electric compressor can achieve a heating efficiency of COP=2 at -30℃. At the same time, the noise is low during operation and the overall design is lighter.

Engineer Weiling introduced that in extremely cold weather, users don’t need to "cover the quilt" to drive. At the same time, compared with traditional heat pump air conditioners, the heat pump with carbon dioxide as refrigerant can increase the cruising range of vehicles by up to 20%.

The CO2 electric compressor alone has 220 domestic invention patents and 14 international invention patents, and has completely independent intellectual property rights. At the same time, CO2, as a common greenhouse gas, is collected and used as a refrigerant, which also contributes to "carbon neutrality".

Last year, the heat pump air conditioning products of Midea Group Weiling components have been installed on pure electric brand vehicles such as Tucki and Weilai, which has become a microcosm of the rapid transformation of domestic component enterprises to electrification.

In 2020, Tesla put the heat pump air conditioner into a pure electric vehicle, which led the electric vehicle industry to take another step towards high efficiency. In just one year, by 2021, heat pump air conditioning has become the standard of high-end electric vehicles.

Obviously, the technology that will not be used in the era of fuel vehicles may be a huge innovation in the era of electric vehicles. In today’s increasingly fierce global competition for electric vehicles, there is still huge room for innovation in the field of electric vehicles.
