On May 3 this year, Chang ‘e VI was launched from Wenchang Space Launch Site in China, and was sent into the earth-moon transfer orbit by Long March 5. In 53 days, Chang ‘e-6 successfully landed in the pre-selected landing area of aitken Basin in the South Pole of Moon Back, and achieved the world’s first sampling and take-off of Moon Back, and successfully returned to Earth with lunar soil on June 25th, with a round trip of more than 760,000 kilometers.

　　Behind this success, there are many unknown stories. A series of reports on the science and technology "Chang ‘e" on the Moon explores the scientific and technological forces behind Chang ‘e’s lunar exploration. Today we pay attention to the five-star red flag displayed on the back of the moon for the first time.

　　"Stone Edition" Five-Star Red Flag is made of basalt.

　　The national flag displayed on the back of the moon on Chang ‘e VI has very special requirements for materials. It is made of "stone".

　　In a quarry in Yuxian County, Hebei Province, a kind of stone called basalt is being collected here. The basalt here is one of the oldest, largest and most complete basalt groups in China.

　　Zhu Zhaochun, Head of Xinyuan Basalt Mining in Yuxian County:Basalt hasHigh toughness, corrosion resistance, acid and alkali resistance, high temperature and low temperature resistance.Excellent performance.

　　Zhu Zhaochun knows a lot about the characteristics of basalt, but what he doesn’t know is that,These characteristics of basalt are the materials suitable for the lunar environment that the Chang ‘e-6 lunar flag development team has been looking for.

　　Wang Yunli, a professor at wuhan textile University, a member of the Chang ‘e-6 lunar flag development team:In the environment of the moon, its high and low temperatures are as high as MINUS 150℃ and above zero 150℃. Because the moon has no atmospheric protection, ultraviolet rays will directly shine on objects. Therefore, for the national flag, it puts forward more stringent environmental requirements.

　　In addition to the characteristics that can meet the lunar environment, the research team also found that basalt is similar to the lunar soil in chemical composition.

　　Cao Genyang, a professor at wuhan textile University, a member of the Chang ‘e-6 lunar flag development team:We found that the composition of basalt on the moon is very complicated through the published literature on lunar soil, with 10 to 20 components, the most important of which is silica. We matched and analyzed the stone and found that its data was very close to the composition of the lunar soil. Finally, we chose the basalt mine in Yuxian County, Hebei Province.

　　In this way, the basalt in Yuxian County, Hebei Province was selected as the raw material for making the Chang ‘e VI national flag. These stones, which have existed on the earth for hundreds of millions of years, have embarked on the road to the moon.

　　Tempered stones become ultra-light and ultra-thin fabrics.

　　There is a very important reason why Chang ‘e VI chose the "stone version" national flag to show the back of the moon.Making national flag from basalt is an exploration of in-situ manufacturing of lunar surface..In the future, it is necessary to use local materials to build a lunar base, and to make basalt on the moon into sheet or tubular building materials for lunar surface construction, which will greatly save costs than using materials on the earth.

　　After the raw materials are determined, how to turn stones into cloth and accurately control the weight?It has become a difficult problem that the development team urgently needs to overcome.

　　The national flag on the lunar surface of Chang ‘e VI has the same specifications as the national flag on Chang ‘e V, and its size is 300mm×200mm, which is almost the size of a piece of A4 paper. However, the density of basalt fiber is nearly twice that of Chang ‘e V national flag, which will lead to the heavier "stone version" national flag. Because it will be used in spacecraft, the weight requirement of the national flag on the moon surface is extremely demanding, and it needs to keep the same weight under the same size. The developer calculated that this requires the density of basalt fiber to be 8.8 grams per 1000 meters so as not to be overweight, but how can such fine basalt fiber be produced?

　　Cao Genyang told reporters that the process control, furnace temperature, spinneret state and so on were constantly being debugged, but no matter how to do it, the density index of 10 grams per kilometer became an insurmountable gap in making basalt fibers. After numerous experiments, it is found in a production process that the trapezoidal optimization of the inner cavity structure of the spinneret and the distributed accurate temperature control in the furnace can solve the problem of insufficient characteristics of basalt fibers.

　　In the end, the development team successfully realized the stable mass production of superfine basalt fiber. The weight of the Chang ‘e VI flag they made was only 11.3 grams, which was 0.5 grams lighter than that of the Chang ‘e V flag.

　　Four years of tackling key problems on the back of the moon perfectly presents "China Red"

　　Ultra-fine basalt fiber has been made, and the next challenge comes one after another. "How to color the fiber made of stone" has become another difficult problem for the development team.

　　Different from cloth, the filaments drawn from stone have a particularly smooth surface, and the pigment cannot be firmly attached to the flag surface. The flag is finished, and the color can’t go up. The research team can only try again and again to find a solution.

　　Finally, based on the experience of Chang ‘e V, the research team used the aramid short fiber hairiness on the surface of the fabric to make the binder in the pigment form a similar "rivet" anchoring effect with it, effectively improving the bonding fastness of the paint interface and the color fullness of the national flag pattern, and ensuring the lunar display effect of the national flag.

　　Researchers told reporters,From a silk to a flag, there are at least forty or fifty steps in the middle process.Compared with the eight-year research on the development of Chang ‘e-5 national flag, the research time of Chang ‘e-6 national flag is particularly tight, and the team members have almost no rest days, all of which are to ensure that this national flag can withstand the "tempering".

　　Dr. Sheng Dan, Ph.D., wuhan textile University, member of the Chang ‘e-6 lunar flag development team:There are four mechanical experiments, and there are three steps in environmental experiments, including pre-test and so on, at least 50 steps. Finally, I took a flag and went through a complete experiment from beginning to end, including the final deployment. Later, when I saw the national flag organization unfolding, I felt very cute and proud when I saw the organization unfolding.

　　The lunar flag development team lasted for nearly 4 years and conquered it.Spinning, Weaving and Color Construction of Basalt MicrofiberAnd many other international problems, the "stone version" of high-quality fabric national flag without temperature control protection and independent dynamic display was developed for the first time, which realized the first independent dynamic display of the national flag on the back of the moon in China. Put the "China logo" on the moon again!

　　Prospects can be expected. Aerospace science and technology will weave "fire-proof magic clothes"

　　While the "stone version" of the national flag was being developed,The lunar flag team started the application research of basalt fiber in the fields of heat resistance and flame retardant.. These research results also make basalt more useful.

　　Natural fibers with golden brown luster are drawn from hard basalt. In the production workshop, a large number of basalt crushed stones are thrown into the blast furnace. At the high temperature of 1500℃, the rocks are melted into liquid, and then drawn into filaments that are almost invisible to the naked eye through the rotating shaft. And this fiber contains a total of 400 monofilaments of 500 microns. Touching a single filament of basalt fiber with your hand makes it feel like a hair filament, silky and extremely tough.Clothes made from them are "magic clothes" with fire-proof function..

　　The cloth made of basalt fiber combined with textile processing can be used as fire clothes in special scenes, and can also be made into household items such as fire curtains and fire mattresses in the future. At the same time, basalt fiber has broad application prospects in road construction, composite materials, new energy vehicles and other fields.

　　Wu Minyong, General Manager of Hubei Huierjie New Materials Technology Co., Ltd.:In the field of new energy vehicles, it can be used as a brake pad and a fireproof cloth for battery modules; In the field of aerospace military industry, we use it as an interception network for space launch sites.

On August 1st, the movie "Catch the Doll", with the excellent performances of Shen Teng and Mary, successfully broke through 2.4 billion at the box office, which injected vitality into the recently slightly deserted movie market. The success of this film is largely due to the re-engagement of the golden combination of "Shen Ma+Yan Fei Peng Damo". In the process of constructing the universe of Xihong City, directors Yan Fei and Peng Damo have already proved their strength through goodbye mr. loser and The Richest Man in Xihong City. These works are all from their hands, and they have also won a win-win situation for Mahua FunAge in word of mouth and box office. Back in 2003, Beijing Free Element Film and Television Culture Communication Co., Ltd., the predecessor of Mahua FunAge, was founded by three young people with different backgrounds, including Yu Kai of Chinese Department of Peking University, You Liang Tian of Chinese Opera, and entrepreneur Zhang Chen. At first, they tried to adapt the novel into a TV series, but it failed because of the influence of SARS. Subsequently, You Liang Tian turned to the field of drama, and released his first work, I’ll give you a twist if you want to eat it. Although it was initially challenged by the box office, it finally found its own audience in Haidian Theater with its unique style and word-of-mouth fermentation, and Mahua FunAge became famous.

The addition of actors such as Shen Teng, Allen, Wei Xiang, Song Yang and Du Xiaoyu further enriched the cast of Mahua FunAge, and many of them joined through internal recommendation, forming a stable team foundation. Mary, in particular, attracted the attention of Peng Damo for her outstanding performance in the small theater, and eventually became an indispensable member of Mahua FunAge.

The turning point of Mahua FunAge appeared on the stage of the Spring Festival Evening. The skits written and directed by Yan Fei and Peng Damo, especially the role of "Hao Jian" played by Shen Teng, gradually made the team members familiar to the national audience. Despite the enormous pressure of the Spring Festival Gala, the Mahua FunAge team boarded the Spring Festival Gala for many years with unremitting efforts and unique creativity, which not only enhanced its popularity, but also promoted the development of its members’ personal careers, and Shen Teng became an important figure in China comedy movies.

In 2015, goodbye mr. loser, the first work of Mahua FunAge’s transitional film industry, was a great success, which not only verified the feasibility of adapting drama into film, but also opened a new chapter in Mahua FunAge’s film. Subsequent works, such as The Richest Man in Xihong City, faced with speculation about the change of creative team, but Yan Fei and Peng Damo still insisted on their own creative rhythm and style and continued to introduce popular works.

Looking at the development of Mahua FunAge, from the initial exploration to becoming the backbone of comedy, it is inseparable from the tacit cooperation of the core team and the continuous exploration of comedy art. Whether it’s a stage play or a movie, Mahua FunAge always maintains the pursuit of quality and respect for the audience, and continues to bring laughter to the audience.

Recently, JK Auto officially released the new model JK 009 seven-seat aisle version, priced from 439,000 yuan to 469,000 yuan.

However, some users have reported that the piano paint panel of the center console is prone to fingerprints, which may affect the convenience of daily use. However, overall, these small problems do not affect the overall performance of the 009 on the interior.

Driving texture and technological innovation

The driving quality of the Extreme Krypton 009 has been significantly improved. Its chassis is equipped with a dual-cavity air suspension system, which greatly enhances the smoothness and comfort of the ride. Whether it is a long-distance drive or a city road, the 009 can perform well, providing both a soft ride experience and strong road feel and handling performance in Sport mode.

As a pure electric vehicle, the 009 also upgraded the battery system and adopted the 800V platform, achieving an amazing charging speed from 10% to 80% in 11 minutes. For users who travel frequently for long distances, this is undoubtedly a breakthrough.

High-end configuration and intelligent experience

The 009’s car system has also been upgraded, equipped with dual 8295 chips to ensure the smooth operation of the large screens in the car. The central control screen adopts a narrow-frame OLED screen, and the image quality is clear and delicate, which further enhances the sense of technology in the car. The rear ceiling TV has also been upgraded to a 17-inch OLED screen, allowing passengers to enjoy a better entertainment experience during long-distance journeys.

It is worth mentioning that the seat design of the 009 is also impressive. The whole car is equipped with the Extreme Krypton Eames recliner, which not only provides zero-gravity comfort, but also fully supports the passengers’ legs and ankles. Whether it is a long drive or a short break, the thoughtful design of the seat can bring the ultimate comfort experience.

The release of Krypton 009 has once again refreshed the market standard of luxury MPVs. Whether it is the appearance, interior, or performance and technology, it shows the brand concept of Krypton pursuing the ultimate. This car not only performs well in domestic and commercial scenarios, but also achieves breakthroughs in charging efficiency and driving texture. As Krypton continues to expand the market, its global layout has also made 009 a new choice for users in various countries. In the luxury electric vehicle market, Krypton 009 is undoubtedly a force that cannot be ignored.

When it comes to boron steel, in fact, many people have little understanding, and some people even confuse high-strength steel with boron steel. Some people say that the proportion of boron steel is particularly high, so it is particularly safe, but this is only half true. In layman’s terms, the use of boron steel is a matter of conscience; the use of boron steel is good, and the use of boron steel is ability.

Yesterday, I was chatting with a friend who is in the same industry. He has been driving the luxury Sedan for more than 3 years and told me that he wants to change the car because his wife has just become pregnant and the smell in the car has not dissipated. I am afraid that it will affect the child and need to replace it.

I: "Do you like it?"

Friend: "I want to see the new intermediate"

Me: "Oh, just because it’s more environmentally friendly?"

Friend: "Hey, not all of them. Everyone says it’s safer. I value this more when I have children."

Me: "Tell me where is safer"

Friend: "I knew the first person to invent the seat belt…"

You see, in fact, sometimes industry insiders don’t have much better opinions on a certain issue than ordinary consumers. For example, my friend didn’t know that the invention was actually "."

The most shining labels on the body are undoubtedly "safe" and "environmental protection". Perhaps because such labels are too eye-catching, many people do not realize where the safety lies under such labels. Its safety core may be as simple as its Nordic appearance.

Externally Soft and Inner "Steel": The Profundity of Boron Steel in Body Structure

When it comes to safety, it must be mentioned; when it comes to materials, some people say materials; when it comes to materials, high-strength steel must be the word with the highest appearance rate. Today we will talk about the story behind high-strength steel. Boron steel, one of the best structural steels, is the guest here today.

"Hello everyone, my name is Boron, and my English name is Boron. 0.001% of the earth’s crust is composed of my brothers and sisters."

Boron is a non-metal, its hardness in nature is second only to stone, it is widely used in the production of nuclear reactor control rods, and can also be used in the manufacture of alloys. Boron steel, as the name suggests, is a steel that is mainly alloyed with boron. After adding alloy boron, the steel has very high hardenability, high wear resistance and good fatigue resistance, and is an excellent structural steel.

Like many scientific technologies, boron steel was first used in the military industry, especially in the aerospace industry and submarine manufacturing. With the vigorous development of the manufacturing industry, boron steel has a new "application". As a large-scale industrial product, in addition to high strength, good craftsmanship is also an important factor, that is, the difficulty of steel processing cannot be too high. The appearance of boron steel and heat treatment technology perfectly meets this demand.

You might ask, "How?"

First of all, the strength is very high, and the nominal strength of boron steel after hot forming treatment reaches 1500 MPa, which has good safety performance.

? Secondly, the forming performance is good. The traditional process of manufacturing complex-shaped parts usually requires multiple ordinary steel parts to be welded, while the thermoforming process often requires only one part to solve this problem. The picture below shows the composite diagram of the vehicle B-pillar assembly. The left side is ordinary steel, which requires several parts to be welded. The right side is thermoformed steel, which is integrally stamped and formed, visible to the naked eye.

Combined with these characteristics of boron steel, it is mainly used as structural steel in the industry. The structural strength of boron steel is greatly increased, which improves the anti-extrusion ability, and then protects the life safety of the occupants in the car in the event of a collision. At the same time, boron steel thermoformed parts are also the most valuable lightweight materials at present. Advances in materials and processes make it convenient for people to travel while meeting increasingly stringent safety and emission regulations.

Known for its safety, it naturally excels in the application of boron steel. Its XC90 uses nearly 40% of boron steel, S90 uses 35% of boron steel, and V90 CC and XC60 use 35% and 34% of boron steel, respectively.

Have you learned this knowledge of boron steel?

Of course, you might say that boron steel is so powerful that the more it is used in the car, the safer it is? Let’s continue to look at it.

"Steel" is soft and easy: tell you

How should excellent design be done?

As an important part of the vehicle, it is necessary not only to meet the aesthetic requirements of appearance and vision, but also to meet the requirements of aerodynamics, man-machine performance, and NVH performance. More importantly, it is necessary to protect drivers and passengers against impact.

Generally speaking, people tend to divide the simple into and, which is often not enough when talking about safety. Stephan Ryrberg, senior principal engineer at the Group Security Center, said that a complete collision should be divided into three stages:

The first stage is the energy-absorbing collision of the front structure. This stage generates a specific energy, and we () want the front of the car to absorb as much energy as possible. So sometimes the front of the car looks badly damaged after the collision, but it actually protects us effectively. Of course, the structure must be energy-absorbing and deformed under strict control.

The second stage is the collision of the occupant compartment, that is, the direct collision between the occupant and the restraint system in the vehicle. Seat belts, etc. protect the occupant by absorbing the impact energy to significantly reduce the energy transmitted to the next stage.

The third stage occurs inside the human body, and different organs will collide with each other in the body. If the structure of the vehicle is well designed, the energy transmitted to the second and third collisions will be weakened accordingly, thus reducing the damage to the human body. "

With these insights in mind, let’s talk about what requirements a person who excels in safety should meet.

01

In the investigation of safety accidents, it is shown that the proportion of occupant deaths caused by frontal collisions is the highest, so in the event of a frontal collision, the energy absorption of the front structure has a significant relationship with the deformation of the cockpit. The greater the deformation of the energy absorption zone in a frontal collision, the more the collision energy is absorbed, and the impact force can be avoided as little as possible to the passenger compartment.

This process belongs to the "energy-absorbing collision of the front structure", and in the design, the front should absorb as much energy as possible to reduce the acceleration of the collision.

In the frame is the energy absorption design of the front structure. The material distribution map clearly shows the design idea. The yellow front stringer and the green front do not use ultra-high-strength thermoformed steel. The stringer uses medium-strength steel, and the front uses an aluminum alloy cavity structure with lighter weight and better energy absorption effect.

This design can ensure that the front structure can quickly collapse in the event of a frontal collision, which absorbs kinetic energy, thus ensuring the integrity of the cockpit. It can be seen that it is not blindly pursuing strength, but choosing the most suitable material in the appropriate part to ensure the safety of the passengers in the car as the first consideration.

Words like "soft" and "crashless" are often used to describe a car that is not strong, but in fact, through professional crash tests such as E-NCAP, C-NCAP, IIHS, etc., it can be seen that the collapse energy absorption design can greatly improve crash safety, that is to say, a reasonable "soft" is actually conducive to safety.

02

The second most common death rate in a car accident is a side collision. Since there is no buffer zone on the side, there is only one fan away from the outside world when a collision occurs, so the strength and the frame strength of the occupant compartment become the foundation for protecting the occupants in the car. Common measures include increasing the strength of the interior; increasing the strength of the sidewall components, including increasing the cross-sectional shape and thickness of the B-pillar and C-pillar; increasing the strength of the threshold beam; installing a beam system at the height of the B-pillar; and installing reinforced beams below and under the rear windshield.

We still take the XC90 as an example. The part in the blue box above is the most important crew compartment. Its importance can also be seen from the distribution ratio of ultra-high-strength thermoformed boron steel. The red thermoformed boron steel is almost all distributed in this area.

As the saying goes, "good steel is used on the blade", hot-formed boron steel is uncompromising "good steel", of course, it must also be used on the "blade".

The thermoformed boron steel with the best yield strength is used in the side-B-pillar-C-pillar-middle channel-lower threshold and the foot pedal area in front of the driver and co-pilot, that is to say, when you open it, all the hidden under the door frames are thermoformed steel with a strength of up to 1500Mpa; when you sit in the driver’s seat, the pedal area under your feet, and under your center armrest, all use thermoformed steel with a strength of up to 1500Mpa. The front, rear, and left of the driver are surrounded by thermoformed boron steel, forming a safe cage structure.

The purpose of this approach is to effectively transmit the impact force to the protective beams, columns, floors, roofs, and other components in the event of a collision, so that the impact force is dispersed and absorbed by these components, which greatly improves the anti-collision ability and overall safety. It is not easy to deform in the event of a collision, and better protects the safety of the occupants in the vehicle.

In addition, the linear and coherent force transmission path design can maximize the absorption and dispersion of the impact force throughout, whether it is a frontal collision or a side collision, the impact kinetic energy can be evenly distributed to the skeleton through a coherent force transmission path, reducing the deformation of the internal space as much as possible at the moment of impact.

　　Asian trend diva Jolin Tsai will sing at the Guangzhou Gymnasium on December 13. Hanging rings, twisting, splitting legs, gravity-free yoga gymnastics, pole dancing, ribbon dancing… These dazzling and difficult movements, Jolin Tsai will also show to the fans again without hesitation. How does she maintain enough physical strength to complete these movements? How does she maintain the figure and skin that has made countless girls envy for many years? Recently, the reporter walked into the presidential suite of the China Hotel where Jolin Tsai stayed to reveal the secrets of the future diet for you – a simple diet can also eat a healthy and good figure!

　　Want a balanced diet? Starchy meat is indispensable

　　If you think that Jolin Tsai doesn’t touch meat in order to maintain a good figure, then you are very wrong. She said that balanced nutrition is the most important thing, and you can’t avoid starch and meat because you are afraid of getting fat. "Because if you don’t eat or eat meat, you won’t have the strength!" Jolin Tsai expressed her lovely and practical concept very directly. She eats a certain amount of rice or bread every day to ensure the intake of starch. "Although I don’t eat much, each meal is a small half bowl of rice, but I won’t skip it." She pointed to the seafood pot and a small plate of chicken in front of her to "explain": "I prefer to eat seafood, but this one has no seasoning, and the chicken is to prepare for the concert to raise yourself more strong. The rings, yoga, gymnastics, etc. are all very laborious." She didn’t think it would lead to weight gain. "It’s so hard to prepare for the concert. It’s great that you don’t lose weight after practicing all day!"

　　Tips for the Queen:

　　Girls don’t need to worry too much about the problem that eating meat will make them fat, because the "threat" of general meat to obesity is not as good as oil and various seasonings. "My nutritionist told me that these are all unhealthy things. In fact, the original ecology of food is the healthiest. So these seasonings will not appear in my diet." Cai Yilin usually only drinks water and fruit juice, "Try to avoid touching sugary drinks, it is easier to make people fat."

　　Can’t quit snacking? Fruit can serve as

　　Looking at the food in front of Jolin Tsai, she could tell that her favorite food was fruit: salad, fresh fruit, juice… She always changed ways to make herself eat more fruit, "Vitamin C in fruit can replenish the body’s water, and it is good for health and skin, which is more important for girls." Fruit is well known for its nutrition, but it doesn’t mean that fruit is the staple food? "It won’t get greasy. I already like to eat fruit, and there seems to be no fruit I don’t like. And when I eat it in different ways, it feels different." Speaking of her favorite fruit, Jolin Tsai, who has always been less talkative, opened the box and became a nutrition expert. " She can almost treat fruit as a snack, "the manager next to him also joked.

　　Diva Recommended:

　　Fresh fruit: original taste, experience freshness and original ecology

　　Fruit salad: If you want to eat dessert, you can use it instead

　　Freshly squeezed juice: can quickly absorb nutrients and is healthier than sugary drinks

　　Afraid of being too light? Pure original flavor is not bad either

　　The most common thing on Cai Yilin’s table is green vegetables. She advocates that it is mainly light, so "blanching vegetables with water" has become a must-order dish. "The vegetables blanched with boiling water do not contain oil and salt, and are more’original ‘, and the nutrients in them are relatively intact." Wouldn’t it be hard to swallow without any taste? "At the beginning, I was not used to it. I always felt that my mouth was moving and I didn’t eat anything at all. But later, when I got used to it, I found that the vegetables themselves have their own taste, which is not bad."

　　It’s understandable to blanch vegetables with water, but if the fish and meat are not seasoned… Cai Yilin said with a smile: "Many of my friends find it incredible when they see me eating these food without color and taste, and sometimes they even say with disgust: ‘Hey, what kind of food is this!’, but they don’t know that I really don’t find these light things unpalatable, and I have even fallen in love with such food."

　　Fun Facts About Diva:

　　Jolin Tsai’s manager revealed that once working late, everyone went to a hot pot restaurant to eat Chongqing Mandarin Duck Pot. Everyone ate heartily, but Jolin Tsai sat in the corner, facing a pot of boiled water without tomatoes, green onions and monosodium glutamate, and rinsed vegetables. Everyone thought she was "pitiful", but in fact she was enjoying the original food with relish.

　　One meal a day? Three meals refused hot topic

　　If you think Jolin Tsai eats one meal a day, then you are wrong again. "I must eat three meals a day, even if I don’t eat much, otherwise I will feel as if I am missing something and will have no energy." The manager next to me added, "When the time is up, she must eat it, and sometimes she has to eat supper at night." Isn’t it easier to get fat after eating supper? It turns out that her supper is still "boiling vegetables with water".

　　However, many girls’ favorite cakes, ice cream, potato chips and other hot topic foods are already distant memories of Jolin Tsai. "I don’t seem to have eaten these things for a long time, and the snacks are all replaced by fruit. The cakes and cookies my song ordered for me are all sugar-free." She doesn’t even remember the "last time" she ate ice cream, "It should be a long, long time, and I forgot why. But what impressed me is that I forgot the taste when I ate it, and I thought while eating it: Oh, so this is the taste of ice cream." The surrounding staff smiled and added: "Sometimes we will deliberately’seduce ‘, but she is unmoved. I admire her persistence, after all, these are great temptations for girls. "

　　Diva comments:

　　"If you want to eat healthy and stay in shape, you have to endure some. It’s a big sin to eat a dry-fried steak without oil every now and then!" She believes that girls need to face these "restrictions" with a different mindset and have enough confidence to maintain them. "I actually enjoy the feeling of being in control of my diet and weight, and the control of my body makes me less susceptible to temptation."

　　Should I take supplements? timely need

　　Jolin Tsai worked hard, so naturally she had to add some soup and supplements. "When my mother came to see me, she would bring me some soup or something, but she had to filter some oils and seasonings, and sometimes add some salt if she felt it was too weak. My nutritionist would prepare some healthy recipes for me according to my physique and performance needs." For example, Jolin Tsai has been practicing gymnastics and yoga more recently, which has high requirements for the flexibility of bone hardness. "So now I need to take more calcium tablets to enhance bone quality and avoid injuries during practice or performance." It seems that Jolin Tsai’s professionalism and dedication are also reflected in her diet.

　　Diva Lessons:

　　Some time ago, Jolin Tsai suffered a skin infection due to the seasonal hair removal of her dog, and was even called a "bad face" when she went to the hospital. "In fact, the media is too exaggerated, and the photos are a little exaggerated," said Jolin Tsai. "I was surprised when I saw it myself. The actual situation is not so scary! But after this lesson, I will often eat some nutrients to enhance my immunity, so that my skin and physical fitness will always be in a good condition."

　　China Daily Online, November 25th-Filial piety is a simple word, but it naturally has a temperature. It is a person’s beautiful and gentle initial heart, and it is also the source of strength for thousands of children to repay their parenting. There are countless stories about filial piety worth sharing. Looking back on the past, "Zi Lu Fu Mi", "Lu Ji Huai Ju" and "Huangxiang Fan Pillow" … … These are all ancient children’s actions to interpret what is called "filial piety". Back to the present, there are still many filial sons and daughters in this society. Recently, the story of a filial daughter in Junlian, Yibin, Sichuan Province not only touched the hearts of Chinese people, but also attracted the attention of overseas media.

　　Hong Kong’s South China Morning Post reported that this sensible little girl named Cai Chengcheng is ten years old this year. When she was six years old, her mother, Li Chen, had a sudden cerebral hemorrhage. After waking up from a coma, she lost her memory, and her intelligence was only equivalent to that of a child of several years old. Because Cai Chengcheng’s father has to run a small shop to pay his wife’s medical expenses, he goes out early and returns late every day. And my brother Cai Lingzhi has just entered high school, and the course is tight, so he can’t help his sister share the heavy responsibility of taking care of his mother. The heavy burden fell on Cai Chengcheng’s tender shoulders. Taking care of her mother, teaching her to read, write and speak, supervising her to take medicine, and assisting her to complete physical training for rehabilitation have become the "daily compulsory courses" for this little girl. She has become her mother’s intimate partner, literacy teacher and rehabilitation nurse … …

　　Although the burden of taking care of her mother is heavy, Cai Chengcheng has no complaints. "When I was a child, my mother taught me to read with a literacy card. Now I teach her. I combine the Chinese characters that I taught my mother with my favorite animals and foods to enhance my mother’s interest. " Cai Chengcheng used literacy cards and associative memory to help his mother deepen her memory. When she taught "Apple", she brought an apple to her mother to smell and recognize ‘ Rabbit ’ Word, let mother hold a rabbit. Cai Chengcheng said in an interview with the media.

　　The report pointed out that after four years, under the careful care of Cai Chengcheng, her mother has been able to help look after the shop and do simple work, and her body is gradually recovering. In these four years, although Cai Chengcheng spent a lot of energy to take care of her mother, she still got excellent grades and served as a student cadre in the school, which was deeply loved by everyone. Cai Chengcheng’s deeds of taking good care of her mother spread, and she won honors such as the third filial piety and virtue teenager in Yibin City, the good teenager in the new era in Sichuan Province, and the candidate of "Looking for the most beautiful filial piety teenager in 2018" by the Central Radio and Television General Station.

　　In addition to the South China Morning Post, Singapore’s Straits Times also reported Cai Chengcheng’s deeds, affirming her persistence in taking care of her amnesia mother for four years. Malaysia’s Star also reprinted the report of South China Morning Post, and actively conveyed Cai Chengcheng’s sincere and pure feelings of filial piety.

　　The story of this little girl also attracted the attention of Chinese and foreign netizens, and everyone cheered for her.

　　Some netizens often ask: "I work outside, and I often don’t have enough vegetables. What should I do if I don’t have enough nutrition?" I always feel uncomfortable if I don’t eat vegetables! Is there any food that can replace the nutrition of fresh vegetables? Can taking multivitamin pills replace eating vegetables? "

　　Indeed, many people go to barren hills or deserts, to foreign countries, to frontier areas and to poverty-stricken areas because of work needs, or for reasons such as teaching and helping the poor. These places often do not have enough fresh vegetables to supply. Even if there are vegetables, they are mostly radishes, cabbages and potatoes, especially leafy vegetables lacking dark green.

　　If it’s ten days and a half, that’s fine. Get over it first, and then make it up when you come back. However, if it is a few months, or even a year or two, the lack of vegetables will inevitably affect your health.

　　As we all know, adequate vegetables are very important for supplying vitamin C, folic acid, vitamin B2, vitamin K, potassium, calcium, magnesium, dietary fiber and various antioxidant substances.

　　Ideally, there should be vegetables in the meal, and 300 to 500 grams of vegetables are eaten every day, and this weight does not include the part thrown into the trash can, but the part that is directly imported.

　　In the case of really not eating enough, you can take the following seven remedial measures. Although it can’t completely solve the problem, it can at least reduce some damage to the nutritional balance and make the body get more comprehensive nutritional and health care ingredients.

　　Temporarily supplement multivitamins.

　　If the dose of vitamin supplements is not too large, close to the normal amount of reasonable dietary intake, taking supplements is harmless. All the worries about supplements are in the case of large quantities. The vitamin content of some products is ten times or even dozens of times the daily recommended value, which is not suitable for long-term use.

　　It must be recognized that although these nutrient supplements can prevent vitamin deficiency, they cannot replace all the health functions of vegetables, such as supplying potassium, calcium and magnesium, dietary fiber, antioxidants and other phytochemicals.

　　Prepare some dried vegetables.

　　You can buy some dried vegetables that can rise after soaking in water, take them to your work area, or order them online. Such as dried seaweed (Undaria pinnatifida, kelp, etc.), dried mushrooms, dried mushrooms, dried fungus, dried bamboo shoots, and evergreen (dried vegetables), as a supplement to the lack of vegetables.

　　Dried products are convenient to store and carry, and it is also convenient to cook dishes after soaking. For example, put some soaked fungus and mushrooms in cooking, add some soaked bamboo shoots and mushrooms in stew and chicken, and add some soaked Undaria pinnatifida in soup, all of which are quite delicious.

　　Although there are fewer vitamins after drying, at least a lot of minerals and dietary fiber can be supplemented. Minerals such as potassium, calcium and magnesium can still be preserved after drying. In particular, most dietary fiber can be preserved, which is very helpful to prevent constipation.

　　Substitute potato, sweet potato, yam and other potatoes.

　　Potato is a kind of food between vegetables and staple food. It contains starch, vitamin C, rich potassium, and some antioxidants, and its dietary fiber content is much higher than that of white rice and white flour.

　　If potatoes are used to replace part of white rice and steamed bread, more vitamin C, B vitamins, potassium and dietary fiber can be obtained on the premise of the same total carbohydrate.

　　For people who need to lose weight, we must pay attention to the fact that when eating potatoes, we should not put oil and salt. Instead, we should put them in a rice cooker and steam them with rice, and reduce the amount of white rice and flour while eating potatoes.

　　For people who need to gain weight, adding some potato foods such as potatoes and yam to their daily staple food, such as stewing potatoes into vegetables, is just conducive to gaining weight.

　　Increase the number of daily vegetables

　　In some remote areas, although there are no fresh green leafy vegetables, there are still some storable vegetables such as Chinese cabbage, radish, onion and carrot.

　　Although Chinese cabbage is not as nutritious as green leafy vegetables, it still contains a certain amount of vitamin C, dietary fiber and minerals.

　　As long as you increase your food intake and eat more Chinese cabbage, you can get more nutrients and partially make up for the loss of insufficient varieties. This is the so-called "quantity compensation for insufficient quality". Carrot itself is a good thing. Eating some often can at least prevent vitamin A deficiency.

　　Send bean sprouts and bean sprouts to increase green leafy vegetables.

　　You can use soybeans, black beans, peas, etc. to soak them and eat them yourself to increase the variety of vegetables. Bud sprouts can spread green leaves as long as they see light, which belongs to green leafy vegetables. Common sprout vegetables include radish seedlings, buckwheat seedlings and peanut seedlings. The sprouts taste good and can be fried. Radish seedlings and buckwheat seedlings can also be eaten raw and cold directly.

　　Even if there are only wheat and barley seeds, they can be made into wheat seedlings, then cut off and beaten into juice with their own beater. This is the best "green juice".

　　It would be better if you could bring some seeds of green leafy vegetables such as Chinese cabbage and rape. You can get fresh vegetables by growing your own vegetables.

　　Order canned vegetables online

　　At present, there are many canned vegetables, such as canned tomatoes, canned green beans, canned mushrooms, canned asparagus, canned pickles, canned corn shoots, canned/bagged ketchup, etc., and the price of ordering in boxes is not high.

　　Although canned food loses some vitamin C, it is not zero, and there is no loss of dietary fiber and potassium. It is convenient for storage and transportation, so direct order is enough. Take it out every day and eat a little at every meal, which still plays a big role in supplying nutrition.

　　With all kinds of flower and fruit tea materials that can be soaked in water.

　　Prepare your favorite tea, coffee, dried rose, dried chrysanthemum, dried roselle, dried lemon, etc., and make a drink with hot water. Although the quantity is limited, it can increase the supply of potassium, vitamin C, organic acids and some antioxidant substances.

　　The so-called methods are always more difficult. As long as these methods are used in combination, we can overcome the difficulty of insufficient vegetables, and make our diet life much richer and healthier.

　　Tomorrow, our mobile phone will be screened by Buffett again!

　　At 22:15 Beijing time on May 4th, the annual shareholders’ meeting of Berkshire Hathaway will be held in Omaha, USA. It is estimated that about 30,000 shareholders will attend, and millions of people will watch it online. The most noteworthy issues of this shareholders’ meeting include:

　　Who is Buffett’s successor? — — Bashen is 88 years old and Munger is 95 years old.

　　What about Berkshire’s more than $110 billion in cash? — — Look at the company’s share price of $320,000. Do you still think Maotai is expensive?

　　The repurchase scale will be as high as $100 billion? — — There are not many good companies worth buying, so I have to buy myself.

　　However, for A-share investors, they may be more concerned about this question: What does Buffett think of the China market? Which stocks of A shares meet its stock selection criteria?

　　Which A shares can enter the eyes of the law?

　　There are many criteria for Buffett’s stock selection, but there are clear quantitative criteria. He only said one sentence, that is, the annual return on net assets (ROE) is greater than 20% for 10 consecutive years.

　　The so-called return on equity (ROE) is the ratio of company profits to shareholders’ equity. It represents the investment income of investors, in short, how much money the enterprise can earn for investors.

　　ROE is a measure of a company’s long-term profitability. The higher the ROE, the higher the net profit it earns with the same shareholder capital investment. According to Coca-Cola’s standard, that is, keeping the ROE above 20% for 10 consecutive years, it is the company that Buffett may like.

　　So, which companies in A shares meet Buffett’s standards?

　　Wind data shows that in the 10 years from 2009 to 2019, among the listed companies whose ROE (deduction/dilution) continuously exceeds 20%, there are only five listed companies in A shares, namely Kweichow Moutai, Haitian Weiye, Gree Electric, Yanghe and Chengde Lulu.

　　The average share price increase of these five listed companies in the past 10 years is 690.49%, and the annualized rate of return is 22.97%. The biggest increase is Kweichow Moutai, which rose 12 times in 10 years, followed by Gree Electric, which rose more than 11 times in 10 years.

　　If we relax the ROE standard to 15%, that is, we will keep the ROE above 15% for 10 consecutive years. So, how many companies in A shares meet this standard?

　　Wind data shows that in the 10 years from 2009 to 2019, there were 14 listed companies with ROE (deduction/dilution) exceeding 15% continuously, namely Shuanghui Development, Kweichow Moutai, Haitian Weiye, Hikvision, Gree Electric, Huadong Medicine, Yanghe, Chengde Lulu, Hengrui Pharma, Chongda Technology, dongfeng shares, Fuyao Glass and so on.

　　The average share price increase of these 14 listed companies in the past 10 years is 551.72%, and the annualized rate of return is 20.62%. Among them, Hengrui Pharma, Kweichow Moutai and Gree Electric rose more than 10 times, while Huadong Medicine, Hikvision and Golden Mantis rose more than 5 times.

　　Is Bashen’s strategy unacceptable?

　　In the past 10 years, what is the investment income of Warren Buffett?

　　According to media calculations, if an investor bought a dollar of Berkshire stock 10 years ago, the return today is about $2.4, but if this dollar is invested in the Standard & Poor’s 500 Index Fund, the return today is about $3.2. In other words, in the past 10 years, the income from investing in Berkshire has not been as high as that from investing in the S&P 500 index fund.

　　In 2018, the worst performance of global financial assets in the past 100 years, the "stock god" seems to be unhappy. Suffering from various "thunder" such as Apple’s performance falling short of expectations and Kraft Heinz’s performance changing face, Berkshire lost more than $25 billion in the fourth quarter of 2018, but still earned more than $4 billion in the whole year.

　　But in A-share market, Buffett’s stock picking strategy still seems feasible.

　　In the past decade, 108 A-share stocks have increased more than 5 times, and 29 have increased more than 10 times. The median ROE of these 29 stocks is 14.88%. During this period, the Shanghai Composite Index rose by 24.72%, the Shanghai and Shenzhen 300 Index rose by 50.2%, the CSI 500 Index rose by 74.59%, and the Shenzhen dividend index rose by 132.51%.

　　Obviously, those companies with long-term earning ability and dividend-paying ability can surpass the market if they buy at a reasonable price. However, it should be pointed out that value investment is by no means equal to an ROE index, and the stocks selected according to it are not necessarily suitable investment targets, but only help us find out those good companies more easily.

　　The above data illustrates two problems:

　　First, as Buffett said: "By investing in index funds regularly, an investor who knows nothing can usually beat most professional fund managers." Buffett has recommended index funds for more than ten times.

　　In Buffett’s view, the vast majority of investors rarely invest in index funds, and as a result, their performance in investing in stocks is mostly just mediocre, or even disastrous. There are three main reasons for the loss of investment stocks:

　　1. The cost is too high, investors buy and sell too frequently, or the expenses are too large;

　　2. Investment decisions are made according to gossip or market trends, rather than after careful consideration and quantitative analysis of listed companies;

　　3, blindly chasing up and down, buying or selling at the wrong time.

　　Second, practice has proved that the companies with the strongest earning power in A-shares can bring rich long-term returns to investors.

　　The overall growth level of A-share listed companies is better than the average level of social enterprises. The long-term stock price trend charts of leading enterprises such as Gree Electric, Vanke A, China Merchants Bank, China Ping An and Fuyao Glass are all consistent with the development path of enterprises.

　　The method of value investment has not failed in A-shares. In fact, A-shares will create a good opportunity for value investors to pick up bargains every few years, making it easier for investors to meet good prices. Numerous masters have emphasized that all investment is to find a good industry, a good company and a good price.

　　Finally, Buffett has bought two China stocks so far — — China Petroleum and BYD.

　　In 2003, Buffett bought H shares of China Petroleum at a price of HK$ 1.6, and cleared the position when the share price reached HK$ 13.5 in 2007, with a four-year income of more than 7 times (the reinstatement factor has been considered, the same below). When Buffett bought it, the P/E ratio of China Petroleum was only 5 times, while when China Petroleum was listed on A-share in 2007, the P/E ratio of 48 yuan’s opening price was as high as 63 times.

　　In 2008, Buffett subscribed for 225 million shares of BYD at a price of about HK$ 8 per share. At present, Buffett still holds shares in BYD, and its latest share price is HK$ 53.55, and its income has exceeded five times. When Buffett bought BYD shares, the corresponding P/E ratio was only 10.2 times. At present, its latest P/E ratio is 39.29 times.
