　　On the morning of April 3rd, the first delivery ceremony of Xiaomi SU7 was held in the assembly workshop of Xiaomi Automobile Factory in Yizhuang, Beijing. Lei Jun, founder, chairman and CEO of Xiaomi Group, attended the ceremony and personally delivered the car to the first batch of car owners. The delivery center of 28 cities nationwide also started the first batch of delivery simultaneously.

　　Earlier in the day, Lei Jun also announced in Weibo that starting from today, Xiaomi will officially become a car factory.

　　Lei Jun said at the delivery ceremony that in just a few days, Xiaomi SU7 had more than 100,000 orders, and the number of lock orders had exceeded 40,000.

　　It is understood that Xiaomi Automobile’s after-sales network has set up 58 service centers nationwide. In terms of car owners’ service, Xiaomi Auto has established an "exclusive service butler group" for every car owner in Xiaomi Auto App. The service butler+technical experts respond to users’ needs 7×24 hours, and the service process is transparent and traceable. Car owners can enjoy the one-stop service of ordering, picking up, repairing and delivering cars from the App without leaving home. In case of vehicle failure, in addition to providing online diagnosis service for 7×24 hours, when users meet the needs of simple disassembly, pure software failure, tire repair, etc., mobile service vehicles and road rescue can also respond at any time to protect users from traveling.

　　At the same time, Xiaomi Automobile Factory is arranging production in an orderly manner for existing orders, and accelerating the production process steadily and orderly. Xiaomi Automobile Factory, located in Yizhuang, Beijing, has the characteristics of high automation and intelligence. After the production capacity is full, a brand-new millet SU7 will be off the assembly line every 76 seconds. Xiaomi Automobile Factory integrates advanced intelligent technology with traditional intellectual innovation, and more than 700 robots directly serve the production line, realizing 100% automation of key processes such as large die casting, stamping, body connection, body assembly, painting and final assembly, fully ensuring production capacity, and finely controlling production quality to ensure that every millet SU7 can be delivered to users quickly and with high quality.

　　It is understood that at present, Xiaomi Automobile Factory is making every effort to increase production capacity, and fully mobilizing supply chain partners to fully guarantee supply. With efficient and high-quality operations, it will steadily promote the delivery of existing orders as soon as possible and the orderly handling of future orders to ensure the delivery experience of users.

　　This delivery will be the founding version of Xiaomi SU7. The non-original versions of Xiaomi SU7 and Xiaomi SU7Max start delivery at the end of April, and the Xiaomi SU7Pro start delivery at the end of May.

　　Regarding the issue of delivery, Xiaomi Auto officially replied that the first batch of founding editions totaled 5,000 units. In order to start delivery for car owners as soon as possible, the way of production in advance was adopted, and very strict standards were set in all aspects of the whole delivery process such as production, quality inspection and logistics. The original version of the vehicle will complete all the production and quality inspection processes in the near future, and it is being sent to 29 cities one after another and delivered to users.

　　Xiaomi Automobile said that it is currently in a state of explosive orders, and there are continuous new lock orders every day. Orders will be scheduled and delivered in the chronological order of the final lock.

　　Earlier, a video on the Internet broke the news that the test drive of Xiaomi SU7 found abnormal sound and leakage. In this regard, Xiaomi Automobile replied that after investigation, it was confirmed that the actual situation was: at about 11: 30 am on April 1, the clerk of Xiaomi Automobile Store in Xiamen stopped after a sudden abnormal noise while taking the customer for a test drive, and found that the vehicle was in a stable state and the chassis was normal, so the car was driven back to the store normally; After detailed inspection in the store, it was found that a stone invaded the position of the brake disc, causing abnormal noise; After the stone is taken out, the abnormal sound is eliminated and returned to normal.

　　As for the water marks around the car body, it is due to the recent rain in Xiamen, and the vehicle has traveled through the water accumulation area. It is normal for the car body to leave water marks after parking. After testing, the whole vehicle has no leakage, no leakage point, the kettle liquid level is normal, and there is no relevant liquid level alarm fault light prompt.

　　It is worth mentioning that due to the expected release of Xiaomi Automobile, the share price of Xiaomi Group has continued to rise since March this year. On April 2, Xiaomi Group’s share price rose back to the issue price, reaching a maximum of HK$ 17.34 per share, up 8.97% on that day. On April 3, Xiaomi Group’s share price fell back. As of press time, the intraday share price was HK$ 15.90 per share.

　　The movie "Mars Rescue" describes the plot of the protagonist trying to grow potatoes on Mars. Now, this vision is expected to be completed by China. In 2018, the popular science payload "Lunar Micro-Ecosphere" will land on the lunar surface as a special passenger on Chang ‘e IV, where potato seeds, Arabidopsis seeds and silkworm eggs will be placed. Two kinds of plants will take root and sprout within the 100-day experimental period and produce the first flower on the surface of the moon. Silkworm will also complete the complete life cycle of egg hatching, larval growth and development and cocoon breaking into butterflies.

　　The reporter of Beijing Youth Daily learned that Professor Xie Gengxin, the chief designer of "Lunar Micro-Ecosphere", said that by the end of 2018, the popular science payload will "ride" Chang ‘e IV to the moon, realizing the first biological experiment on the surface of the moon. This biological experiment will be broadcast live to the whole world through a small camera.

　　On June 18th, Xie Gengxin, the chief designer of "Lunar Micro-Ecosphere", was interviewed by Beijing Youth Daily, and introduced in detail the idea and process of this biological experiment, such as planting potatoes on the moon. In Xie Gengxin’s view, although many difficulties need to be overcome, this experiment is of far-reaching significance. It will be the first lunar biological experiment for human beings, which is of great significance to the future survival of human beings on extraterrestrial planets.

　　The first biological experiment on the surface of the moon

　　Beiqing Daily: Why was there such an experimental idea at the beginning?

　　Xie Gengxin: Actually, growing organisms on other planets is an area that many countries are studying. China’s previous exploration has landed on the moon, and this experiment is another innovation in the exploration process.

　　Beiqing Daily: Who is conducting this experiment?

　　Xie Gengxin: This project is a popular science load led by Chongqing University. It has been an experiment for more than two years. In addition to Chongqing University, Hunan University, Beihang University, China Aerospace Science and Technology Group and other universities and enterprises have also participated in it, involving multiple R&D teams with interdisciplinary subjects such as machinery, control, environment, biology, optics and energy. There are more than twenty staff members at the core of the team.

　　Beiqing Daily: What is the "lunar micro-ecosystem"?

　　Xie Gengxin: This is a cylindrical device, with a height of 18 cm and a diameter of 16 cm. It is made of aluminum alloy, and the national flag of China and the signs of Chongqing University and Research Center are affixed on the surface. The weight of the whole popular science load lunar micro-ecosystem is 3 kg, but its cost is more than 10 million yuan, and the camera alone is 600 thousand yuan.

　　Beiqing Daily: Compared with other countries, what is the international position of this exploration?

　　Xie Gengxin: This exploration in our country is the first biological experiment on the moon, which is ahead of the United States, Russian and other countries. This exploration will also prove that among many countries in the world, our country’s space exploration is changing from the previous follow-up to the leading and leading stage.

　　Different from the first flower in outer space opened by NASA space station in the United States last year, our experimental location is 380 thousand kilometers away from the earth, which is much farther than that of the International Space Station, which is more than 300 kilometers away from the ground.

　　Planting with large temperature difference and strong radiation on the moon faces many challenges.

　　Beiqing Daily: What are the difficulties to overcome this time?

　　Xie Gengxin: On the moon, it is 14 consecutive days of daylight and then 14 consecutive days of darkness. The high temperature can reach more than 100 degrees Celsius, and the low temperature drops to more than 100 degrees Celsius below zero.

　　In addition, the ultraviolet rays on the moon have not been filtered, and the survival of animals and plants needs to face harsh environments such as high radiation and microgravity. This is far from the living environment on earth. These are all difficult problems to overcome.

　　Beiqing Daily: What do potatoes, Arabidopsis and silkworms live on?

　　Xie Gengxin: Our "lunar micro-biosphere" is actually simulating the living environment of animals and plants on the earth. The device will contain water and equipped nutrient solution, and the temperature in the jar will be kept between 1℃ and 30℃ through certain technology, and the humidity and nutrients inside will be controlled well.

　　In addition, the photosynthesis of animals and plants is carried out by absorbing the natural light of the moon, and there is no light in the whole device. The light pipe in the "jar" absorbs the natural light on the surface of the moon for photosynthesis, and the released oxygen is absorbed by silkworm eggs, and then the silkworm eggs discharge carbon dioxide and domestic garbage for plant seeds.

　　Beiqing Daily: How can animals and plants carry Chang ‘e to the moon to overcome the overweight problem?

　　Xie Gengxin: A difficult problem in the experiment process is how to fix the seeds and silkworm babies in a "jar" so that they will not be scattered due to overweight and other pressures during launch.

　　We have repeatedly calculated the design and weight of the container, for example, because the soil is too heavy and the utilization efficiency is not high, we chose nutrient solution, and the seeds and silkworm babies have also been fixed under overweight conditions through technology.

　　Potatoes are expected to be a food for human beings to survive in space.

　　Beiqing Daily: Why did you choose potato, Arabidopsis and silkworm?

　　Xie Gengxin: First of all, from the biological conditions, the selected plants and organisms should be relatively resistant to high and low temperatures, and the growth cycle should not be very long. After experiments, these three kinds of animals and plants are relatively qualified.

　　In addition, the choice of potato is also to provide support for the next step of human survival in space. At present, many countries and research institutions in the world regard potato as the main food for human survival in space.

　　Secondly, the choice of animals and plants will also be close to the life of ordinary people and conform to the cultural tradition of China. Potatoes are the most common food, and silkworm babies are cute. There is also a step of breaking cocoons into butterflies in the growth cycle, which has a good moral and symbolizes the progress and innovation of China in space exploration.

　　Beiqing Daily: Is the potato cultivated in the later period expected to become human food?

　　Xie Gengxin: It’s a possibility. We will conduct experiments on the earth at the same time and under the same conditions, and compare and analyze the data of the two. Through experiments, it is possible that the quality and yield of potatoes planted on the moon are relatively high, but this needs further research.

　　Beiqing Daily: Is it possible for humans to survive on the moon in the later period?

　　Xie Gengxin: If plant seeds can germinate, grow and bloom in this environment, silkworm eggs can hatch normally, larvae can grow and develop, and break cocoons into butterflies, which shows to some extent that it is not a dream for human beings to live on the moon.

　　If the experiment is successful, it will provide technical support and lay a foundation for human beings to carry out the survival of extraterrestrial planets. Just as the micro-ecological circle on the moon is infinitely large, theoretically, human beings can also live on the moon.

Forget glugging countless glasses of water or getting your beauty sleep. The secret of looking young is simply to stay out of the sun.
Stop being crazy about drinking water and sleeping beauty sleep. There is actually only one secret to staying young: staying away from the sun.

A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are.
After investigating hundreds of women, a study found that those women who stay away from the sun’s radiation look 20 years younger than their actual age.

However, other supposed rules for a youthful complexion, from drinking lots of water to sleeping well and exercising regularly, failed to hold back the hands of time.
Other universally recognized principles of maintaining youthful appearance, such as drinking more water, sleeping beauty sleep and exercising regularly, can’t stop the ruthless years from leaving marks on the face.

Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a difference, the American Academy of Dermatology’s annual conference will hear today.
The annual meeting of the American Academy of Dermatology will announce this discovery: only by staying away from the sun, or wearing sunscreen when you have to be exposed to the sun, can you resist the years for several rounds.

The intriguing finding comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-worshippers.
This interesting discovery comes from a study of 231 women of all ages. The researchers conducted a questionnaire survey on their living habits, including whether they like to bask in the sun.

When researchers from Massachusetts General Hospital in the US – commissioned by skincare firm Olay – guessed how old the women were, they found those who took care in the sun tended to have aged more slowly.
Subsequently, commissioned by Olay, a skin care company, researchers at Massachusetts General Hospital estimated the age of these women and found that women who took sunscreen measures aged more slowly.

A lucky four had so few wrinkles and age spots, and such a glowing complexion, that they appeared to be a full two decades younger than they really were.
Four of them have almost no wrinkles and age spots, so radiant that they look twenty years younger than their actual age.

Researcher Dr Alexa Kimball, a professor of dermatology, said the popular perception that we drink lots of water to stay healthy is a myth and the body is ‘pretty good’ at judging how much we need.
Researcher Dr. Alex Kimble, a professor of dermatology, said that the popular view that drinking more water can keep you healthy is nonsense, and our bodies can accurately judge the amount of water we need.

Previous research by the British Nutrition Foundation reached a similar conclusion.
Previously, the British Nutrition Association’s research also reached a similar conclusion.

Experts there said: ‘Just drinking water for the sake of drinking water really has no effect on improving the appearance of skin.’
Experts from the association said: "Drinking water for the sake of drinking water really won’t improve the skin."

It isn’t clear why the women who slept well didn’t have younger-looking skin. But it may be that the question they were asked was too narrow and didn’t take into account their long-term sleep patterns.
As for why women with good sleep quality can’t have younger skin, the reason is not clear. However, this may be because the coverage of the questionnaire is too narrow and the long-term sleep patterns of the subjects are not taken into account.

A second study, also by Olay, suggested that low-level day to day exposure to the sun is more ageing that occasional, intense blasts.
The second study initiated by Olay Company shows that frequent exposure to low-intensity sunlight is more likely to make people aging than occasional exposure.

Finally, DNA examination of tiny samples of the women’s skin gave some insight into the damage done by the sun.
Finally, the researchers conducted genetic testing on female skin samples, which gave us a general understanding of the damage caused by sunlight to the skin.

A gene called CDKN2A was more active in facial skin that is exposed to the elements than on samples taken from the buttocks.
The researchers found that the gene named CDKN2A is more active in facial skin exposed to sunlight than hip skin away from sunlight.

This gene was also more active in women who said they loved the sun – and in those who looked older.
The gene is also more active in women who love sunshine-and these women look older.

Dr Kimball said CDKN2A activity is a sign that a cell is ‘tired out’ and urged women should protect their skin year round and not just when on a beach holiday.
Dr. Jin Bo said that the activity of CDKN2A gene means that cells are actually in distress, so she called on women to take skin care measures all year round, instead of waiting for a beach holiday to think about sun protection.

Dr Frauke Neuser, principal scientist at Olay, which has used the research to develop its latest face creams, said: ‘This research gives us a detailed picture of the effect of sun exposure on skin ageing and illustrate the importance of protection on a daily basis.’
Dr. flock Neuhser, the leading scientist of Olay, used these research findings to develop the latest cream. He said: "This study gives us a detailed understanding of the effects of sunlight on skin aging, indicating that daily skin care is very important."

　　CCTV News:In 1990s, American football star O·J· Simpson’s "suspected wife murder case" caused a sensation, which was also called "trial of the century". Although Simpson was acquitted in that year, in 2008, the famous American black sports star was jailed for "kidnapping and armed robbery". On the 1st, after serving nine years in prison, seventy years of age Simpson was released on parole.

　　The Nevada Bureau of Corrections and Rehabilitation confirmed that Simpson left Lovelock prison in northern Nevada at 0: 08 am local time on the 1st after signing the release papers.

　　Although the American media generally predicted that Simpson would be released on parole at the beginning of this month, the Nevada Bureau of Corrections and Rehabilitation released Simpson in the early hours of Sunday, which was somewhat unexpected. This also enabled Simpson to avoid the media when he was released from prison. After he got out of prison, he was picked up by an unidentified friend.

　　Former football star Simpson was jailed for robbery.

　　In 2007, Simpson and others clashed with two sports souvenir sellers in a hotel in Las Vegas, Nevada, trying to snatch thousands of dollars worth of souvenirs with guns — — Simpson claimed that the photos, badges and football souvenirs were his own belongings. After the incident, Simpson was arrested by the police and charged with 12 counts including kidnapping and armed robbery.

　　In 2008, the court sentenced Simpson to 33 years in prison, but he could be released on parole after nine years.

　　In July this year, four members of the Nevada Parole Adjudication Board voted unanimously that Simpson was "unlikely to commit another crime" and agreed to grant him parole.

　　"Trial of the Century" — — Simpson’s "Suspected Wife Killing Case"

　　Simpson was once a star of the National Football League. In June 1994, Simpson’s white ex-wife and boyfriend were found dead in their residence in Los Angeles, and all the evidence showed that Simpson was the biggest suspect — — The case was a sensation, but after a tortuous trial, Simpson was acquitted by a jury in October 1995. This case, known as the "trial of the century", has caused public controversy about the fairness of the American judicial system, highlighting the differences of opinion among different ethnic groups in American society.

We often see such remarks as "anyone who looks good and has a good figure looks good in anything" and "even if he grows up like this, he looks good in a sack". It is generally believed that only those who look good and have a good figure have the right to beauty. This lack of self-confidence in appearance and figure has become a stumbling block for many ordinary people to become beautiful.

In fact, people with good looks and good figure will only take fewer detours and be more beautiful than ordinary people, but they will also face the same problems as us. As long as we take good care of ourselves, it is not impossible to overtake in the corner.

In fact, there are many ways for ordinary people to become beautiful, and there is no need to make a big move, change a hairstyle, find the right style of wearing, enlarge the advantages, etc. This degree of beauty is more suitable for our reference.

Then in this issue, let’s talk aboutHow do ordinary people exert their strength in clothes if they want to be beautiful?Why do people look beautiful casually? Three "fashion rules" that you don’t know are the key. Let’s take a look:

In fact, there is an unbreakable law in both fashion and beauty industry, that isCreate "perfection".

And you will also find that those good-looking looks, makeup, and clothes are also in the public aesthetic. What hairstyle to choose, what makeup to paint, and what to wear are all in the direction of good-looking looks or good proportions.

Based on this law, it is not difficult to understand why we will"proportion"Put it in the first place.

Just like building a house, the proportion is the foundation. Only when the proportion is built, the whole will not collapse. And a good proportion is like a reference. If you build it like this, you won’t make any big mistakes.

So what is a good ratio? How to create a good ratio?

First of all, a good proportion looks comfortable and balanced, and it can be divided into two types: horizontal and vertical.

1. Vertical proportion

Vertically, in the aesthetics of length, we generally recognize that the good proportion is 9 heads and bodies. But this is more difficult for the public, so we will wear it to make it as close as possible.3:7、4:6The balance ratio, as long as your dress ratio is in between, at least it won’t look stretched.

On the contrary, if your clothes are 50-50, no matter how fashionable you dress and how beautiful your colors are, you won’t look good visually:

The vertical proportion is simply the "waist line", which creates a visual sense of legs below the chest. For example, we can use belts, tops, and knots to show the waistline, which not only adjusts the proportion of body shape, but also shows the beauty of dress.

2. Horizontal proportion

Vertical proportion is common, and what we tend to overlook is horizontal proportion.

Horizontal proportion, that is, the contrast between length and width, is also the key for people who want to be tall and thin. We should shorten the horizontal proportion and make the figure look taller. Can be obtained fromtightnessThink in this direction.

① Up and down tightness

A more unified concept is that wearing loose pine is not good-looking. First, there is no proportion. Second, loose clothes are easy to get fat. Even if it is worn in proportion to the length of the upper part, it lacks a sense of beauty visually:

For wearing up and down, if you want to create a balance, then"One loose and one tight"It will be more in line with the public aesthetic. For example, "tight on the top and loose on the bottom", "tight on the top and loose on the bottom", or "loose on the top and tight in the middle", so that the balanced wearing will not appear loose and sloppy.

② Internal and external tightness

By the same token, it will look better to keep the inside and outside wearing loose and tight than in Quan Song.

Clothes that are loose inside and outside are easy to appear procrastination and lack of aesthetic feeling;

For this kind of wear, "tight inside and loose outside" and "loose inside and tight outside" will look better. It should be noted that wearing tight inside and loose outside will be more inclusive to the body shape, which is more suitable for chubby women. The wearing of "loose inside and tight outside" is more suitable for creating a good proportion, and it is more suitable for people with poor proportion, small people or thin people.

The easiest fashion for ordinary people to wear in winter isOverlapping,Although it is very common, it is not easy to wear it well. We have sorted out the following three overlapping ways:

1. Foundation overlapping

The first is the basic overlapping, which is also a way for everyone to get easily. Simple overlapping is "sandwich" wearing, that is, the combination of inside+single item+coat. What we need to know about this combination isSelection of clothesandThe creation of neckline.

There are four main points:

① Choose a thin and close-fitting style for the interior, and it can be pulled flat;

② The exposed neckline should avoid stacking as much as possible, and a single layer is the best;

3 choose a mid-high collar to wear, revealing a little neck part to be slim and beautiful;

4 Exposing the neckline, cuffs and hem will have a more layered feeling.

2. Body shape overlapping

On the basis of overlapping, we need to consider whether the figure is suitable. For example, the upper body is fat, the chest is big, or there is a belly, so at this time we should pay attention to the changes in details.

Upper body fat: the middle layer can be worn with unbuttoned clothes such as thin shirts, and only part of the inner layer can be exposed to make it slim;

Big chest: also choose shirts or V-neck clothing, and create V-neck lines at the neck;

Small belly: the inner belt doesn’t need to be completely inserted into the lower garment, and it will cover the meat more by tucking a corner or using a belt.

In addition, there are two smaller details when using the overlapping technique for slightly fat women:

First, choose dark colors for the interior and light colors for the outside; The second is to put a silk scarf on the neck to expose the edge, which can also play the role of overlapping, which is very suitable for people who are worried that overlapping will make them fat.

3. Advanced overlap

In addition to the basic overlapping, there is another way that overlapping is relatively rare and easy to wear novelty, that is, to choose the overlapping of coats and coats. For example, coat+suit jacket+turtleneck shirt, replacing a light shirt with a suit, can make the dress look more neat and straight.

Or change the suit into jeans and leather clothes, etc. The mix and match of materials and styles can make the dress more interesting. However, this kind of wearing is also very easy to appear bloated, which is not suitable for slightly fat women.

For ordinary people, the simplest and fastest skill to improve clothes is to learn color matching, which is not too complicated. Simple color application can increase the wearing power and fashion sense, for example:

1. Base color+embellishment color

Most people will choose the basic color to wear, and many people may think that wearing it like this can create a simple sense of high-level, but in fact, for ordinary people, wearing it like this will only appear single, boring and ordinary, because the sense of high-level needs temperament and details.

It is easier for ordinary people to master"base color+embellishment color". That is, when the whole body is basic color or monotonous, choose a small area of bright colors for embellishment, which can make the dress look more detailed.

for exampleGray coat+red embellishment,A large area of gray or black will be slightly dull and monotonous, and a little red at this time is the key to improving color and finishing touch.

At the same time, you can also use the technique of mutual echo between small areas to make the wearing look more exquisite. For example, if you choose shoes, bags, hair bands and other accessories with the same color as a single product, the colors will echo each other, and the visual unity and harmony will be very aesthetic.

2. Bright color+Shun color/Black/White

The echo of colors can also be put on the wearing of bright colors. For example, when a dress you choose is bright or you don’t know how to match it better, then choosing a similar color matching can have an extended visual effect and look very beautiful.

Of course, if the color is too bright, the safest way is to choose the basic color white or black, which has the effect of transition and inhibition, so that the color looks less vulgar.

Recently, some netizens asked at the "I Jinshan" WeChat public account of "I Jinshan" in the Jinshan District Rong Media Center, Shanghai, and asked: "Xiaobian, Xiaobian, 48 hours have passed, why hasn’t the community notified notification?"

In this regard, "I Jinshan" replied: "The region management and control investigation is a dynamic adjustment process, and it is not said that it will be automatically unblocked in the community in 48 hours. Only when all personnel in the region control the community have been detected twice within 48 hours, and the resultIt is normal. After the comprehensive research and judgment of the previous epidemic prevention and control department can be issued, the unblocking instruction can be issued. Once the nucleic acid test results in the region are controlled abnormal, the control time will be extended accordingly. "

"I Jinshan" added: "The number of nucleic acid detection has soared in the near future, and the test report time is relatively prolonged, which affects the time and control time. The current situation of the epidemic prevention and control is severe and complicated.The principle of less contact and less gathering "promotes home online office."
