Super subway passing through the center of the earth

　　In the movie "Total Memories", a 13,000-kilometer-long "fall road" passes through the center of the earth. Passengers can get on the train and reach the other end of the earth in 17 minutes. This is really a shocking idea. You know, it takes 22 hours for a plane to fly to the other end of the earth, because it flies an arc along the sphere, and "falling into the road" is a model of shortcuts. In fact, falling into the road does not violate any existing laws of physics. Of course, there are countless engineering problems waiting for scientists to solve in order to be truly realized.

　　Suppose the "fall road" is really built, and you jump in from an entrance, what will happen? It depends on which two places on the earth's surface are connected by the "fall road". If it is the north and south poles, gravity will accelerate you continuously, and in just 13 minutes, you will enter the center of the earth at a speed of 35,000 kilometers per hour. At the center of the earth, you will be in a state of weightlessness as an astronaut in space, because at this time you receive equal pull from all directions of the earth. Once you cross the center of the earth, your speed will slow down until you reach the other end of the earth steadily. The whole process only takes 37 minutes.

　　Why should it be emphasized that it is the "fall road" connecting the north and south poles? This is because the "falling road" connecting other locations will be affected by the Coriolis effect. The earth keeps spinning. After you jump off the "falling road", you will soon hit the wall of the "falling road" because of the rotation of the earth. Of course, it is easy to overcome this, as in the movie "Total Recall", using additional power to offset the Coriolis effect.

Wormholes connecting distant galaxies

The earth leaves its orbit in science fiction movies

Cross the interstellar through a wormhole

　　In the movie "Interstellar Crossing", passing through the wormhole enables the protagonist Cooper and others to reach a distant and unfamiliar galaxy in a very short time.

　　So what is a wormhole? Why does it have such a wonderful effect? In 1935, physicists Einstein and Nathan Rosen proposed a concept of a channel connecting two black holes-the Einstein-Rosen bridge, based on general relativity.

　　In 1955, when American physicist John Wheeler was studying the mathematical model of Einstein-Rosen Bridge, he proved that it is possible to connect two different regions in the universe. Wheeler believes that the Einstein-Rosen Bridge is not like a bridge, but more like a hole left by a bug biting through an apple. An ant has two choices from one end of the apple to the other. One is to crawl around the curved surface of the apple, and the other is to bite through the apple and drill through. Obviously the latter is harder but faster. Imagine that in a higher latitude space, if the three-dimensional space-time we are in is curved like an apple peel, then the "wormhole" passing through the high-dimensional space entity will inevitably allow us to move faster in the three-dimensional space. Between the two points in, the term "wormhole" that has swept the world was born.

　　In 1987, Kip Thorne, a theoretical physicist at the California Institute of Technology, together with two of his graduate students, proved that a wormhole can be opened, but it requires enough material with negative energy. What is negative energy? Quantum fluctuations in vacuum have energy. If the energy of a substance is lower than the energy of quantum fluctuations in the surrounding space, it is said that the substance has negative energy.

　　Unfortunately, the negative energy created in this way is too insignificant to be used to keep the wormhole open. In fact, maintaining the opening of a wormhole requires a huge amount of negative energy, the total amount of which is almost equal to the total energy released by an ordinary star in a year. So far, wormholes are still beautiful legends written on paper.

The planet is the spacecraft

　　In the sci-fi movie "The Wandering Earth", when the sun suddenly ages and helium flashes may occur at any time, mankind is united and decided to use the entire earth as a spacecraft to escape to Proxima. You know, whether it is to stop the rotation of the earth, leave its original orbit, or let the earth fly out of the solar system, the strongest power is needed.

　　Under the leadership of the coalition government, mankind made every effort to build more than 10,000 planetary engines on the Eurasian continent, and built dozens of more powerful steering engines on the equator. The energy of these 11-kilometer-high, 20-30-kilometer-diameter engines comes from "refusion." The "refusion" here means that under extreme high temperature and pressure, heavy elements can also undergo nuclear fusion.

　　The most abundant elements in the earth's crust are oxygen and silicon, accounting for 49% and 26%, respectively. With the refusion technology, humans can throw the dug out stones into the engine into energy, and use energy to push the earth. Each planetary engine produces 150 trillion tons of thrust, and more than 10,000 planetary engines are enough to propel the earth to the third cosmic speed in about 5 years-16.7 km/s, which is the lowest speed from the sun's gravity.

　　The mass-energy conversion efficiency of refusion is extremely high, and the output energy is huge, but the earth is really too big and heavy. The most optimistic estimate is that for the earth to reach the third cosmic speed, billions of tons of stone must be burned, which is equivalent to digging 40 meters of the world's ground as fuel. When the 2500-year voyage is over, how much of the earth will be left when it enters Proxima’s orbit?

　　Although judging from the current technical conditions, "falling road", "wormhole", and "planetary spacecraft" are all bold imaginations in science fiction movies, which cannot be truly realized. But in the future, with the advancement of science and technology, they may also become a reality. You know, no one believed that humans could make aircraft that are much heavier than air.

 　　The 2020 Nobel Prize in Physics was awarded to three scientists who have made important contributions to the study of black holes. Soon after this, new research findings on black holes appeared in the journal of Science. Scientists discovered that the "small universe" formed during the expansion of the universe was likely to give birth to the most primitive black holes.

　　This series of research was completed by several members of the Kavli Institute of Physics and Mathematics of the University of Tokyo (Kavli IPMU).

　　Dark matter is regarded as the main component of the universe. The gravitational wave signals that people observe and the super-large black holes found in the Milky Way or other galaxies may all originate from dark matter. Before the birth of primordial stars and galaxies, black holes formed in the early universe, and these primordial black holes are likely to be important components of dark matter.

　　In order to study primordial black holes, particle physicists, cosmologists and astronomers from Kavli IPMU formed a research team to start with the early evolution of the universe and find conditions conducive to the formation of black holes.

　　According to the theory of cosmic expansion, during the rapid expansion of the universe, early galaxies and star clusters began to evolve. At the same time, many "small universes" emerged. These vacuum bubbles are likely to be different from the existence of our existing universe. It will collapse, but the huge energy released by the relatively small volume is likely to lead to the production of black holes.

　　For a small universe with a larger volume, if its size is at a certain critical value, according to the theory of relativity, the small universe can be observed from two angles: inside and outside. If it is inside, the observer can see it as an expanding universe, if it is outside, the observer can see it as a black hole. Regardless of the angle, researchers can regard the small universe as the embryonic form of a black hole, which hides the basic structure of multiple universes behind the event horizon.

　　The event horizon is a kind of boundary. What happens inside the horizon cannot affect the outside of the horizon. The periphery of the black hole is the event horizon. The escape speed here is faster than the speed of light, so any object (even light) cannot escape.

　　Previously, the research team had introduced candidate events for primitive black hole observations in journals. In the scientific journal, the research team described a new possibility for the formation of primitive black holes.

　　The research team used the Pleiades Cluster Telescope in Hawaii and its second-generation Hyper Suprime-Cam (HSC) to show the observation data in multiple small universe scenes. If a primordial black hole passes through a stellar galaxy and reaches a star in the line of sight of a telescope, the black hole's gravity will bend the light and make the star brighter than usual in a short period of time. According to the duration of the star's brightening, the mass of the black hole can be measured. With the help of HSC, human beings have the ability to observe hundreds of millions of stars at the same time, so as to "cast a wide net" to find those primitive black holes that are passing through the galaxy.

　　At present, the research team is launching a new round of observations and expanding the scope of the search to further verify relevant conclusions.

　　The research team also showed the HSC observation data, some of which coincide with the rudiments of heavy black holes and supermassive black holes observed by LIGO.

　　A series of numerical studies have shown that if it can be determined that the HSC observation object is the main source of dark matter, then further optical surveys and research can provide more evidence for the formation of primitive black holes.

 　　As the world's population continues to increase, so does the demand for meat. However, the growth rate of pigs, cattle, sheep and other animals is far behind the needs of humans, and some diseases also make meat production unstable. Is it really difficult to eat meat in the future? With the development of science and technology, the emergence of artificial meat may solve this problem. There are two types of artificial meat: one is plant artificial meat, which is mainly made from soy protein; the other is animal artificial meat made from animal stem cells.

What is plant artificial meat made of

　　Strictly speaking, plant-based artificial meat is not real meat, but a food made of plant protein. Under normal circumstances, the main components of plant artificial meat are plant protein, pigments, stabilizers, preservatives, water, oils, and flavoring agents. Among them, the first three raw materials have the most obvious influence on the appearance, taste and nutrition of plant artificial meat. At present, a variety of minced and muscular plant-based artificial meats have been developed. The artificial meat currently available on the market is basically plant-based artificial meat.

▲ Artificial plant meatloaf

　　Plant artificial meat is "meat" made by imitating the shape and taste of meat. One of the reasons why people like to eat meat is because there is a special substance (heme) in meat. When this substance is heated, it will activate internal reactions to produce chemical substances. This chemical substance is the source of meat flavor, so As long as there is such a substance in plant artificial meat, the success is half. Scientists have discovered that there is this special substance in soybeans, protein is extracted from other beans, color is extracted from vegetables, and fat is extracted from nuts. Putting these substances together can make plant-based artificial meat. .

The development process of animal artificial meat

　　Animal artificial meat is truly derived from animals, and its production process is: first extract a small piece of meat from a living animal, and this piece of meat contains stem cells. Then this piece of muscle tissue is filtered and separated into muscle stem cells and fat cells. Next, place the required muscle stem cells in a petri dish, and put a nutrient solution in the petri dish. The nutrient solution provides the muscle stem cells with necessary nutrients, such as amino acids, vitamins, carbohydrates, etc., so that the cells feel that they are still there. In living tissues, instead of being separated out, so that cells can continue to replicate. One muscle stem cell can be cultivated into trillions of muscle cells. These cells gradually grow into viscous muscle tubules. When they increase, they will form a ribbon. At the same time, they will continue to expand and stretch to resemble meat silk. These cultivated meats are almost the same as real meat in terms of organization and structure, and can be said to be real artificial meat. And in the cultivation process of artificial meat, you can also choose which fat to let into it, making it more conducive to human health, such as adding omega-3 unsaturated fatty acids that have the effect of protecting the heart.

　　When people hear that the cells of animal artificial meat are differentiated from stem cells, they worry that it is genetically modified food. In fact, no genetic engineering is required to cultivate animal artificial meat, so it is not a genetically modified product, but real meat. Scientists believe that this kind of artificial meat is safe to eat, chemical additives are cultivated from natural nutrients, and viscous powder and coloring agents are strictly in accordance with food process standards. Because scientists eradicate any diseases that may occur in livestock, animal artificial meat is even safer than real animal meat.

　　In fact, animal artificial meat is nothing new. Someone proposed this idea as early as the end of the 20th century. It did not become a reality until 2013. The inventor was Mark Post of Maastricht University in the Netherlands. In 2013, Mark creatively invented the first artificial beef pie in the laboratory. Mark used muscle stem cells to cultivate 20,000 small muscle fibers and knead them together, and finally made a "beef patties."

　　Speaking of Mark's development of artificial meat, it can be described as ups and downs. As early as 2005, Mark had the idea of ​​developing artificial animal meat, and the Dutch government provided academic funding for Mark’s whimsy. But 4 years later, Mark has not yet developed it, and the Dutch government cancelled its funding. Unwilling Mark embarked on the road of independent research and development, but, after all, biologists are not super rich, and the project has been stranded several times due to lack of money. It wasn't until 2011 that luck came again when the family foundation of Google boss Sergey Brin noticed this new project and injected follow-up research funds into Mark. Two years later, under the gaze of 200 people, Mark showed everyone his research results-a beef burger costing as much as 250,000 euros, and he was called "the first person to breed meat."

What are the advantages of artificial meat

　　From the current point of view, the advantages of artificial meat are relatively obvious.

　　1. greener

　　traditional animal husbandry requires a lot of resources, such as an important source of feed, land, water, livestock methane is also a greenhouse gas. Compared with traditional animal husbandry, the production of artificial meat saves 87% of water resources and 96% of land resources, reduces 89% of greenhouse gas emissions, and is more conducive to the future development of the earth and mankind.

　　2. nutrients can effectively control the artificial meat

　　for the traditional meat reared it in a way that we can not effectively control the quality and nutritional content of meat, can only passively accept. The advantage of artificial meat is that it can effectively mix various nutrients, which can ensure that the produced artificial meat has a healthier nutritional composition and ratio.

　　3. be less slaughtered many animals

　　around the world over one billion animals are slaughtered to satisfy the appetites of more than 70 million people each week. Compared with traditional animal husbandry, which requires a long breeding period, artificial meat can be produced in large quantities in a short time. Once artificial meat becomes popular, humans can breed less and slaughter many animals less.

　　4. healthier

　　excessive intake of red meat (cattle, sheep, pork, etc.) are considered to pose health risks. According to the recommendations of nutritionists, one person should not consume too much red meat every week. In contrast, plant-based artificial meat has the advantages of being delicious, not fat, zero antibiotics, and zero cholesterol.

　　5. satisfy vegetarians, dieters and animal protection requirements of

　　global vegetarians, dieters and conservationists are many. The appearance of artificial meat is a huge boon for them. The emergence of plant-based artificial meat enables them not only to adhere to their own principles, but also to take in the necessary nutrients, and to taste the taste of meat.

What are the problems with artificial meat

　　Additives 1. Plant Nutrition and artificial meat

　　meat nutrition primarily protein and fat, protein is essential nutrients, there are 22 kinds of amino acids alone, 8 of the body is neither synthesized, required from food Obtain. But meat happens to have these 8 kinds of amino acids. Therefore, humans eat meat not only to wrap the belly and taste, but also to supplement the nutrients needed by the human body. However, the currently developed plant-based artificial meat has relatively simple nutrition compared with real meat, and cannot meet the nutritional needs of the human body. Plant artificial meat contains more additives such as pigments and flavoring agents in the production process. The safety of the use of various new additives in the production and processing cannot be ignored. It is necessary to conduct a systematic and scientific safety assessment of the new components added in the production.

　　2. psychological problems

　　even able to do a perfect taste, adequate nutrition, consumers still have to cross the psychological barrier. According to a foreign survey, 80% of people are unwilling to eat artificial meat in the laboratory, worrying about long-term hidden risks. Chinese consumers' awareness of artificial meat also needs to be improved. According to a survey data in 2019, 80.8% of the respondents said that they would not buy artificial meat mooncakes. They all want natural and pure food.

　　At present, the artificial meat promoted in the market is mainly plant artificial meat, and the cultivation of animal artificial meat is still in the experimental stage, and there are no animal artificial meat varieties officially on the market. So far, there are no mature conditions for the large-scale production of animal artificial meat, and there is still a long way to go.

 Company value is delivered through products

　　How to display the value of a company has always been a problem that companies must solve. Valueless companies cannot survive. In what way is a valuable company to deliver value is a very difficult problem to choose. It happens that products can play a role in it.

　　To study the success of a company, many people start from the corporate strategy, but I prefer to start from the product. When determining the price of a product, many companies fail to understand that the product itself does not reflect the price, but instead reflects the company's value pursuit. If we only understand the market from the product price, it can only lead to the dilemma of competition in the market. This is also a common problem for Chinese companies.

　　Only by starting from the company's pursuit of value and delivering the company's value through products can customers and the company establish a value choice relationship. Once such a relationship of value choice is established, the company can return to the customer's pursuit of value and make contributions.

　　Xiaomi mobile phones are a good case. Xiaomi has created a high-quality smartphone specifically for enthusiast-level mobile phone controls. The founder Lei Jun said when he talked about why he made Xiaomi mobile phones, as far as the current development trend is concerned, China is the world of mobile Internet in the future. Smartphones and applications will carry most of the needs of users, although in the past many years, a lot of money has been spent on mobile phones. , From Nokia, Motorola, Samsung, to the current iPhone, there are many unsatisfactory places such as poor signal and disconnection during the day. As a senior mobile phone enthusiast, I know that only a high degree of software and hardware combination can produce good results and have the ability to enhance the user experience of the mobile Internet. Based on this idea and ideal, another group of entrepreneurial partners with passion and dreams contributed to the driving force behind making Xiaomi mobile phones.

Connecting employees to products inspires real vitality

　　How to stimulate the vitality of employees is a fundamental issue that companies pay attention to. People think about this issue from different angles. More companies choose incentive mechanisms, corporate culture construction, and create a new organizational environment.

　　I agree that these efforts are all necessary, but instead of achieving these efforts, the vitality of employees is stimulated, and even more difficult is that the vitality stimulated can only be maintained for a period of time. After a period of time, the employees will show up again. The original state cannot be changed. But in fact, observing a dynamic company, you will find an exciting phenomenon: vitality comes from the interaction between employees and products. For example, the following companies.

　　3M,

　　which is considered to be a dynamic company, employees talked about the development of new products, each employee is proud to be able to innovative products, the result is the company from top to bottom are constantly releasing enthusiasm.

　　Southwest Airlines

　　This small airline, in simple and plain cabin to create a happy and enjoy the journey, for 20 consecutive years of sustained growth and profitability, more importantly, to create customer acceptance of new aviation mode. Every employee is a representative of Southwest Airlines' service products, and every employee truly feels the happiness brought about by happiness, thus inspiring the power of every employee to bring happiness to customers, and making the product a value link that connects individuals and teams.

　　Sea fishing

　　sea fishing experience shows that employees feel good has a remarkable significance. Haidilao starts with the food, clothing, housing and transportation of employees and provides them with good services. These measures make employees feel special treatment, and because of such treatment, they feel the company's respect and cherishment for them, and they have developed a sense of pride and mastery in their hearts. Once this feeling becomes the consensus of employees, it will play a huge role. Haidilao gives employees the feeling that the company cares about their employees, and this feeling has also created the employees' caring for customers.

The product carries the "spirit"

　　Today's consumption is no longer purely material consumption. What people need is to satisfy spiritual pursuits through consumption. The emergence of many high-spirited products and services on the market is sufficient to illustrate this phenomenon. Observing the market, it is not difficult to find that successful products must resonate with customers. Consumers must achieve value recognition through product consumption. The most common approach is to provide spiritual pleasure beyond function.

　　The Danish futurist Rolf Jensen believes: "We can say that 1999 was a critical point, when Europe and the United States began to clearly discover that the information age will not continue. In other words, humans We are about to enter a new era—an era dominated by stories. We will transition from emphasizing information to pursuing imagination!"

　　He cited the egg story to illustrate this point. In 1990, almost all Danes bought eggs produced on industrialized farms, and only a few chose eggs from natural farms. After all, the price of eggs produced naturally was twice that of "industrial" eggs. By 1999, half of the eggs in Danish supermarkets came from free-range chickens. The product is the same, the taste is the same, and even the laboratory can't find the difference between the two. Customers desire the romance of nature, rural feelings and animal welfare, and they would rather pay for it. It can be seen that "we now choose products that contain touching stories." His conclusion is that "when we shop, we actually look for stories, friendship, care, lifestyle, and character in the product. We are buying affection."

　　If a product can’t adhere to people’s imagination and yearning, the product will not survive. Maybe we can interpret it with a series of concepts such as "emotion", "spirit" and "dream", but all of these describe a The fundamental fact is that it is a product with a soul, not a simple function and structure.

　　The products people consume are no longer the products themselves, but the emotions and expectations of consumers themselves. Consumers reflect their thoughts, expectations and even dreams on the products, hoping to use the products to sustenance, feel and even vent themselves.

 　　A harsh cell phone ringing rang, and Phil felt inexplicably uneasy. He subconsciously took out his mobile phone from his pocket and glanced at the caller ID, it was an unfamiliar number.

　　"Hello." He answered the phone.

　　A sullen and distorted growl came from the other end of the phone, "Your wife is in our hands."

　　"Sorry, what did you say?"

　　"You listened to me. Her life or death is up to you."

　　Phil Gang I wanted to speak, but the other party continued.

　　"Raise $1 million in cash by midnight tomorrow night. Don't mark it. I'll call again and tell you what to do next."

　　"Who are you?" Phil asked.

　　"It's not important. We have your wife in our hands. You just need to know this."

　　Phil sighed. "Are you kidding? Who the hell are you?"

　　"No kidding. One million dollars." "The other party paused, then said, "Don't call the police. If I see a police car within a mile of your house, she will die."

　　"What if I refuse to pay?"

　　"Don't play with me ." Tricks, sir. Hurry up and raise money, or you will be at your own risk."

　　"Listen, you idiot," Phil said, "I won't give you a dime, no cents."

　　"You..."

　　did not wait for the other party. After speaking, Phil rushed to say: "Now it's your turn to listen to me. I won't pay the ransom. Do as I say, and let my wife go before midnight tonight, otherwise I will take out double The money takes your dog’s life. Your accomplices are willing to let them kill their mothers for 2 million."

　　"You don't know what you are talking about. Your wife is very dangerous now."

　　Phil smiled and said, "I don't think so. You can't succeed. I hope you understand this." He glanced at his watch. "My wife must be sent home before midnight tonight. Don't whisper anymore. Otherwise, I will Spending 2 million will kill you. Are you willing to take a gamble?"

　　"Listen, man, I'm talking about a deal with you—"

　　"Me too, friend. Don't you think that 2 million will let you right away? Are your accomplices backwatering? Actually, I can buy them with 1 million, and your life is worthless." There

　　was a silence.

　　Phil changed his ear to listen to the phone, and sat down, waiting for the answer from the other party.

　　"Now I'm going to hang up. I hope you don't live far enough to get her home before 12 o'clock." Phil glanced at his watch again and continued, "It's 6 o'clock now. Have a good time. "

　　He hung up the phone, put the phone in his pocket, then got up from the sofa, stretched his waist, and walked into the kitchen. His wife Maggie was busy taking the roast out of the oven inside.

　　"Oh, here you are," she said, "I'm about to call you to eat." She put the barbecue on the table and asked casually, "Who called?"

　　Phil picked up the knife and cut off a slice. Thin slices of grilled meat, placed on a plate, said lightly: "The number is wrong."

 I found myself missing my mom and dad quickly, as well as our cat, and our sloping field full of small rocks. But I dare not say what I miss in my heart. I cried at night, but when I thought of the words "man", my tears stopped immediately.

My master didn't have much words, only a pair of sharp eyes, which looked at me instead of a thousand words. I often use these eyes to guess what he is going to say. Once, I felt that there was such a plea in his eyes: "Call me godfather." I yelled softly. He got a little closer to me and touched the back of my head with his hand, exactly the same as Dad's actions.

The time it takes to get acquainted with the master and get close is the same as the time it takes to get close to the cat. It treats me exactly the same as the master. After the master stroked my head, it jumped into my arms and rubbed my chin. When I was alone with it, I asked in a low voice: "Goddad led you to catch fish, right?"

My nose is always inseparable from the fragrant fishy smell. The most remarkable thing about the master here is the tempting fish sauce. It is made of fish, it is fish. It can be said that you can eat fish every day in the master's place. This is an amazing fact that a mountain person would never dream of. I forcefully suppressed the surprise in my heart, and observed and enjoyed it casually.

The little stone house of the master looks short and short, because it lies a large part of the ground; if it enters inside, it will feel tall and bright. It was connected to the shed outside by a small door, and a tunnel made of stones—it was almost a lovely little labyrinth. There are large and small altars and pots in the tunnel, which contain all kinds of delicious things. There are many sundries hanging in the shed, such as pepper bunches, garlic bunches, bunches of herbs, and some leather ropes and cloth strips. Sheds and tunnels can also be entered from the outside, but you have to remove cover such as firewood to find the entrance.

A light green jar was filled with fragrant fish sauce, and the cat squatted on it as if guarding it.

The master also has a piece of land, but it is very small, only the size of two kang noodles. But this small piece of land is extremely fertile, and the master has made it extremely fine. There is no stone in the ground, and there are no larger clods. Vegetables are planted in the fields, including leeks and eggplants, as well as peppers, cabbage and beans. There are still a few melons near Shiyan, and the melons are about to be ripe. The master led me to work in the fields, weeding and loosening the soil. The smell of the melon became stronger and stronger, and the master smiled and picked it up to share with me. We sat side by side on the weir, eating melons. I have been in the hut for a long time, and for the first time I saw the smile on his face.

After staying for more than a week, I discovered that the master had another piece of land. It was on a hillside farther away. It was made up of small pieces just like ours. Sweet potatoes and corn are grown here. Although they are not as refined as the small vegetable garden below, they are much better than ours. The crops here are not short of water, which is a miracle.

Everything depends on that well. Next to a climbing cypress, there is a well platform with a potter's wheel installed on it. I looked down from the well and found that there was a bark of water, which clearly reflected my shadow.

Before it was cold, there was more work in and out of the hut. What did the master do and what I did, he just did it and hardly said anything. Together with him, I harvested the grain from the ground, picked the red hot peppers, put some sweet potatoes in the tunnel, and cut the rest into strips for drying. We chopped some pieces of wood and piled them into a "Tic Tac Toe". After the sweet potatoes are steamed, they are cut into strips and dried, then mixed with fine river sand and fried into sweet potatoes in a pot. This approach is exactly the same as ours. In addition to sweet potatoes, there are fried peanuts and fried beans. The fragrant smell is all over the house, making me happy all day long.

After all the things are done, winter has not yet come. The master stood in front of the hut and looked at the sky to the south, and tied the corners of his pants with a piece of hemp rope. He picked up a basket and looked at me. I knew he was going to take me out. We were one after another, and the cat followed at the back.

Coming out of the valley, heading east and south, turning into a deep valley. Here are some fallen trees and dead reeds. White sand is exposed where there is no grass, which reminds me of Shaheji. The master stopped in front of some fallen trees, then carefully stepped on one of them, motioning me to follow.

It turned out that there were a few puddles at one end of it, the water surface was not big, and grass mustaches covered all around. I remember seeing such potholes and water before. They are all accumulated when there is a lot of water in the summer, and they are too late to dry up. But there are more puddles and puddles, and the color of the water is darker. The master made a gesture to silence me, and then squatted down on the edge of a pit. He tapped a branch on the water a few times, and the grass's whiskers on the water's edge moved slightly. He handed the basket in my hand and rolled up his sleeves. The cat followed, its head moved up and down, its eyes fixed on the owner's hand, and then at the grass beard.

Then something happened that I couldn't understand, and it happened under my nose.

The master just squatted quietly, watching, without saying a word. Suddenly, the five fingers of his right hand were pinched together, and the grass beard was inserted into the "swish"... There was a jump and flutter in the water, and a big two-stranded fish was dragged out, and the master's fingers were stuck on the gills of the fish. The fish's tail slapped fiercely...I couldn't help exclaiming, the cat was terrified by me.

There was the big fish in the basket, and we walked back. My heart is beating, I must open my mouth to gasp. I walked behind the master and followed closely. I secretly admired: It's amazing! What a master! Dad, you are not mistaken at all, he is the King of Fish! Seeing that he didn't take any effort, he caught a big two-stranded fish out of the water as soon as he stretched out his hand...

Along the way, I thought of the green water in the place where I went to school. How many fish should there be in such a big piece of water! Then there are the puddles and potholes that my dad and I have seen before, and how many fish should be hidden! Finally, I thought of a question that was in front of me: what would the master do with this fish?

I dare not say anything, just wait to see and see what he does with this big fish.

Back in the house, the cat slowly walked around the big basket of fish. All cats walk slowly like this when they are happiest. Some people thought it would jump at that time. It was wrong. When it was the most proud and happiest, it always paced and sniffed so unhurriedly. The master cut the fish apart, washed it, removed the scales, and cleaned it up in a blink of an eye, then spread the sauce and sprinkle with salt and pepper. I sneezed a lot because I was so close.

The oil in the pot was ready, the fish poured in, and the cat yelled with me. We can't stand such a big smell, oil and all kinds of weird fragrances. The master ignored us, he just used a wooden shovel to quickly flip, slap, and then add water. The lid of the pot was closed, and white gas spurted out.

I couldn't stay aside, only to look and smell a little further away. My nose can't stand it. I was forced into a corner by the smell of this big fish and the various smells made by the master, where I opened my mouth in surprise. I dare say that there will never be a man like a master in the entire mountain, who will do this like a big fish.

The pot continued to spray white gas. The master set a table with chopsticks and a steaming pot on the small table next to him. I was surprised again because I smelled the smell of wine. I gritted my teeth and kept silent.

The master greeted me and the cat to the small table. He put fish and soup in a large bowl, and added fish and soup to the bowls for me and the cat. Unlike the cat, the master and I both have a cup with dark brown old wine poured in it. Hot wine, I have never drank it before. This fish is too big. The master ate, the cat ate, and I ate too.

I have tasted this wonderful taste for the first time. I pursed my mouth, ate meat, drank soup, and inhaled. The master asked me to drink, so I took a sip. This is a strange smell. After drinking a small cup, my heart is hot and very happy.

"Child, should have made such a meal for you!" The corner of the master's eyes was a little moist.

I whispered: "Master, godfather..."

This is the most remarkable thing that happened in the little stone house before the winter. I am very happy here, so I miss my father and mother even more.

This is how winter comes. In the winter in the mountains, the people outside are unimaginable. People in the mountains have been busy for a year, mainly to survive the winter. Heavy snow, north wind, and roars like monsters came from the mountains in the middle of the night. These add up to frighten us in the mountains.

But in the master's cabin, everything is not terrible. The kang is always hot. I lie on it and listen to all kinds of sounds outside. I think back and forth about some things. Sometimes I feel like I'm dreaming. I fell asleep somehow, and the dream really appeared. There are various scenes in dreams, some make people happy, some make people sad. In the dream, my father came holding my mother's hand, standing in front of me and looking at me, I put my hand behind me. I smiled and suddenly raised my hand behind my back, with a big fish jumping around in my hand. I also had this dream: the master became a big eagle, and I flew and flew on his back, flying to the middle of a big water that I had never seen before.

There are almost always fish and water in the dream.

When the wind gets louder at night, I will involuntarily snuggle up to the master, and he will pat my back to comfort me. When I had a nightmare, I got into his arms tightly, and he held me all the time. I yelled in my dream: "Dad, daddy..." To my right is goddad, and to my left is a cat. I woke up from a dream and hugged the cat, its four claws against my chest and stomach. I kissed its forehead, it licked my arm.

The winter in the small stone house is better at night than during the day.

 When it comes to genital itching, everyone first thinks of vulvovaginitis. But in fact, in addition to vaginitis, vulvar pruritus involves many types of vulvar diseases, such as folliculitis and eczema. What I want to introduce to you today is a common gynecological disease that can cause genital itching-lichen sclerosus of the vulva. Because it is often accompanied by changes and degeneration of the skin and mucous membranes of the vulva, it was also called vulvar leukoplakia, sclerosing atrophy of the vulva, and vulvar dystrophy.

Histopathology is the gold standard for diagnosis

It is generally believed that the age of onset of vulvar lichen sclerosus has two peaks, the most common in postmenopausal women (mean age 52.6 years), followed by prepubertal girls (mean age 7.6 years). At present, the etiology and pathogenesis of the disease are still unclear, and may be related to immunity, heredity, endocrine and metabolism. In addition, oxidation, local irritation, infection, abnormal cell proliferation and balance, cell and blood vessel damage, changes in human epidermal growth factor, lack of trace elements, and psychological factors may also be related to the onset of the disease.

The most common symptom of the disease is intractable itching, which usually occurs at night. In severe cases, it can affect daily life and sleep. Other accompanying symptoms may include vulvar pain, dysuria, dysuria, sexual dysfunction, pain during sexual intercourse and bowel movements. Nearly 10% of patients can be completely asymptomatic, usually discovered by accident or by a doctor during a gynecological examination.

The skin lesions of vulvar lichen sclerosus mainly involve the labia, clitoris foreskin, perineal body and perianal skin, mostly symmetrically distributed, and usually do not involve the hair growth area of ​​the labia majora. The skin of the vulvar lesion area is fragile, mostly manifested as purpura, erosion and chapped. If the lesion is not treated in time for a long time, it can cause invagination of the vulvar structure, loss of the labia minora and clitoral foreskin or front and back joint adhesions, which will eventually lead to the vaginal opening or (and ) Anal stenosis.

Doctors can initially diagnose the disease based on symptoms and physical examination, but the diagnosis usually requires a histological biopsy of the vulva. Special reminder that under the following circumstances, a vulvar skin biopsy should be performed to rule out vulvar intraepithelial neoplasia and malignant tumors:

1. Intractable hyperkeratosis, persistent ulcers, erosions and erythema, new verrucous or papillary lesions, thickened skin and suspected tumor-like or malignant lesions.

2. According to the standard treatment effect is not good.

3. Combined with cervical or vaginal intraepithelial neoplasia.

4. Unexplained pigmentation or decline.

Topical topical corticosteroids as first-line treatment

Except for some prepubertal patients who may be relieved naturally, most patients with vulvar lichen sclerosus require active intervention and treatment. Because the disease is easy to diagnose and difficult to treat, and early diagnosis and early diagnosis can improve the long-term prognosis, it is emphasized that even if there are no symptoms, treatment should be given to delay the progression of the disease and improve the long-term prognosis.

At present, the domestic academic circles (including obstetrics and gynecology and dermatology) have not yet unified the understanding of this disease, and there are great regional differences in treatment options. On the whole, for the treatment of this disease, we must first pay attention to lifestyle changes, including:

1. Choose loose and breathable cotton underwear, and don't wear airtight chemical fiber underwear to avoid moisture and friction of the vulva;

2. Keep the skin of the vulva clean and dry;

3. Disable irritating drugs, detergents or soaps to clean the vulva;

4. Light diet, avoid tobacco and alcohol, and do not eat spicy, irritating or allergic foods;

5. Avoid scratching;

6. Apply petroleum jelly, cod liver oil, vitamin E and other moisturizing creams to keep the skin moisturized.

Secondly, drug therapy can be carried out on the basis of non-drug therapy, including local topical drugs and systemic drugs.

Glucocorticoid is its first-line treatment, 0.05% clobetasol propionate ointment is the first choice. Topical glucocorticoids are divided into two stages: induction therapy and maintenance therapy: choose 0.05% clobetasol propionate ointment in the induction therapy stage, once a day for 4 weeks, then once every other day for 4 weeks, and finally every week 2 times, lasting 4 weeks, 3 months in total. Maintenance treatment stage, once a week, lasts for life. If symptoms or signs recur as the frequency of medication decreases, the frequency of medication needs to be re-adjusted and increased. After the clinical symptoms are relieved, the dosage will be gradually reduced to maintain.

0.1% tacrolimus cream and 1% pimecrolimus can be used as second-line treatment drugs. Most literature reports that the symptom improvement rate of such preparations is about 34%, and the lesion clearance rate is about 24%. Long-term oral use of tacrolimus has the risk of inducing lymphoreticular endothelial cell tumors and vulvar cancer. Therefore, the US Food and Drug Administration (FDA) recommends continuous use for no more than 2 years. Topical 0.1% tacrolimus cream is used for treatment, and the recommended duration is limited to 16 to 24 weeks.

The effective rate of drug treatment is about 80%, most of which can only improve symptoms but cannot be cured, and long-term medication is required.

For patients with obvious symptoms of nervousness, itching and insomnia, the use of systemic sedative, sleeping and anti-allergic drugs under the guidance of a doctor can also have a certain relief effect. In the past, topical progesterone, testosterone propionate, estrogen, oral retinoic acid or photosensitizer treatments that have been widely used in the past are not recommended for routine use due to lack of evidence of clinical benefit.

Patients can also choose physical treatments such as fractional laser, photodynamic, and focused ultrasound under the evaluation of doctors. If medication or physical therapy is ineffective, or the disease is at risk of malignant transformation, surgical treatment is required. Surgical methods include resection of local lesions of the vulva, simple vulvectomy or vulvar adhesion lysis. Surgical resection alone cannot achieve the goal of radical cure. Generally, drug treatment is still required after surgery.

Finally, I remind everyone that lichen sclerosus of the vulva is a chronic progressive disease, and the prolonged course of the disease can cause anatomical changes, dysfunction and even malignant changes in the vulva. For this reason, long-term follow-up is extremely important. The follow-up time is generally 3, 6, and 12 months after treatment, and then every 6 to 12 months. Patients should pay attention to avoid local mechanical damage in daily care, such as not wearing tights or hard seat. In addition, because urine can induce and aggravate the condition, it is necessary to avoid skin contact with urine as much as possible, wipe it dry after urination, and use moisturizing cream before and after urination or swimming to maintain skin moisturization.

 We asked young Indians why they lied to be vegetarians? Last year, when the Indian Burger King’s new menu quickly became popular because it offered burgers with a unit price of about 50 to 70 rupees, Shiluti found that she was also eager to enjoy a chicken burger that met her budget and taste. "When I was in graduate school a year ago, I didn't have any hesitation before ordering burgers or fried chicken nuggets," she said. She asked not to reveal her last name because she did not want her peers to discover the moral dilemma she faced with food.

Before people are vegetarian, eat meat secretly

Recently, this 22-year-old from the outskirts of Mathura, a city in northern India, came to the metropolis of Mumbai to work in fashion design. "But nowadays, whenever I interact with my peers, I worry that I will be rejected (because of eating meat), because they all seem to lead a very ecologically conscious life," Shiluti said: "But by socializing By showing my vegan diet in the media, I not only found a social foothold in the company, but also felt that this lifestyle has made me recognized and appreciated, which I have never experienced before."

"However, after spending nearly half a year with friends in my new social circle, I realized that many people are pretending to be a vegetarian lifestyle. I know interns and artists who pretend to be (vegetarian) every day. I have met A health columnist, she writes about her vegetarian lifestyle for a famous magazine, but she often eats meat in reality." Nowadays, Shiluti avoids ordering meat when dining with friends or colleagues, "but on weekends. When I was alone in the apartment, a large portion of grilled chicken and curry fried shrimp were my favorites."

Pretending to be a vegetarian has been around for a long time

The global enthusiasm for plant-based diets and more and more studies emphasizing the benefits of vegetarianism on human health and animal welfare have largely promoted the vegetarian revolution in big cities in India. India is often hailed as the vegetarian capital of the world, but contrary to this popular belief, social and psychological complexity points to the other side.

“Only about 20% of Indians are vegetarians, which is far below the percentage implied by common sayings or stereotypes,” an anthropologist Natrayan and economist Jacobs published in 2018 widely spread. Wrote in his research paper. They said: "Although it is no longer so popular in Indian cities to view this from a holy perspective, the act of eating chicken (or any other kind of meat) highlights the long-standing struggle between secular and religious: this can clearly become An action to resist religious conservatism and weaken the rule of the caste system."

The study also shows that the custom of pretending to be vegetarian can be traced back to previous generations; the paper records that “people try to say less about the fact that they eat meat, especially beef, and exaggerate their vegetarian behavior”, and “more Many men do not eat at home, and they are less likely to be morally condemned than women.” The author urged people to participate in investigations on whether they lied about food options on social networking sites, and explain the reasons behind the lies. Thirty-one people answered anonymously, saying that they did so to avoid conflicts in the value system, to maintain their status in society, or to avoid being expelled from their religious groups.

"Green Guilt" and Free Choice

Such hypocritical routines can also be observed in the United Kingdom and other countries. A survey found that more than 6 million British people admitted to pretending to be vegetarians. At the same time, India is entering an era of "performance environmentalism" in which social and cultural trends draw people's attention to issues such as climate change and force them to consider the impact of their actions. This allows more people to use white lies to deal with their inner "green guilt" instead of participating in a greater movement aimed at bringing real change.

"We live in a world where words such as'global warming,' carbon footprint,'pollution and' extinction can be seen everywhere," said Bavan, who has 36,000 followers on Youtube and calls himself a "vegetarian traveler": "I lie Call it a vegan because people definitely want to see more content with vegetarianism as the core from me, which is very attractive on social media."

However, in addition to social recognition and "green guilt" in India, there are some social and psychological forces that seem to drive people to be dishonest, and these forces are playing a greater role. The dietary norms contained in Indian religious culture have given birth to a new generation of "fake vegetarians"-when they are with their family and even friends, they indulge in vegetarianism or vegetarianism prescribed by their religion, but When they are alone, they are addicted to meat eating again.

Abinaf, 23, grew up in a conservative Hindu family in Mumbai. He and his sister have been told since childhood that cruelty to animals is an unholy cruel act driven by consumerism. This way of life is instilled in them, not out of their own choice. Soon after he started working out in college, he didn't want to live a vegetarian life anymore. "I started eating chicken rolls when I was 20, and I was convinced that I needed animal protein to maintain my hard training," he said. "Then I expanded to milk, eggs and occasionally eat sausages on pizza." He has been to his parents for many years. Lie: "I don't think there is any problem with this. I want to experience everything I want, and then adapt to a culture that makes me feel truly in line with my values."

Kumari, a behavioral and cognitive psychologist at the Institute of Human Behavior and Joint Science in India, believes that the rise of pretending to be vegetarian is a rebellion against Indian conservatism. “Young people connect with a vast world of ideas and experiences through social media. Opening up and exploring different cultures is the key to developing a secular personality,” she said. “At the same time, speak up for individuals and stand up for things that are contrary to religious beliefs. It is regarded as disrespect and ridicule of the social system. This is the primary reason why many people decide to hide their choice or lie to their families."

 Bomber jacket

　　Many fashion items appeared during the war, and they are still the “darlings” of designers. Such as a bomber jacket.

　　It originated from the heavy-duty flying leather jacket used by the US Air Force to protect against wind and warmth during World War I. It was designed specifically for the cold, non-enclosed cockpits of US fighter jets at that time.

　　The color of bomber jackets tends to be black, military green or leather original colors. The lining is usually made of eye-catching orange satin, so that in the event of a dangerous emergency landing, the pilot can turn the jacket over and ask for help.

　　Although this design no longer has practical functions, it has been retained due to its bright color contrast.

　　In the movie "This Killer Is Not So Cold", the little girl Matilda wears a classic bomber jacket.

Windbreaker

　　The windbreaker also appeared during the "World War I".

　　The trenches are wet and muddy all year round, and water often accumulates in the rainy season.

　　The two main military uniforms at the time were woolen coats and raincoats. The former is not waterproof and will become very heavy when wet; the latter is waterproof, but its rubbery texture makes it very unpleasant.

　　The windbreaker came into being.

　　Now, the windbreaker has become a clothing that everyone can wear on various occasions, and has gradually evolved into a fashion element.

tie

　　During the Roman Empire, when husbands went to fight on the front lines, their wives would prepare a scarf for them to hang around their necks for them to bandage and stop the bleeding during the war.

　　Later, in order to distinguish between soldiers and companies, scarves of different colors were used, and ties came into being.

　　Like corsets and skirts, ties show people's gender characteristics and symbolize a sense of rational responsibility. This was exactly what men were pursuing at that time.

Horn button coat

　　The horn button coat originated in Belgium. With its thick fabric and windproof and wear-resistant characteristics, it was listed as a must-have item by the Royal Navy during the "World War I".

　　Of course, to talk about the iconic "character" of the horn button coat, one has to mention a movie-"Paddington Bear". From 1958 to the present, Paddington bears have been wearing the iconic blue horn button coat.

　　Because the British Field Marshal Montgomery particularly likes to wear this kind of coat, it also has a name called "Montgomery Coat".

　　Until now, horn button coats are still popular in all countries, whether it is Japanese TV dramas, Korean TV dramas, British TV dramas, or American TV dramas, the horn button coats are indispensable.

Ivy style

　　School uniforms first originated in Europe, but at that time they were still called uniforms.

　　The Ivy League has not only cultivated promising young people, but also cultivated a dressing trend called Ivy Style.

　　Most of them use plain shirts or sweaters as the base, casual suits or baseball uniforms as the exterior, and pair them with jeans or slacks. This is a business-oriented but student-like outfit.

　　Ishizu Kensuke promoted this "Ivy style" to the world.

　　During a trip to Princeton University, he discovered the magic of these East Coast student costumes. So he named this style the Ivy style. In his opinion, Japanese men at the time had a great prejudice against fashion, and his own brand urgently needed to launch a new product line for young people, so that young men could change their views.

　　The popularity of the ivy style in Japan is almost synchronized with that of the United States. In the manga "Fantastic Boy" serialized by Osamu Tezuka since 1961, Saburo Onishi has already put on an ivy-style costume.

　　Originally used as clothing for campus culture and sports leagues, under the admiration of Japan, it has unexpectedly become one of the current fashion elements.

Martin boots

　　The appearance rate is very high, and the unisex Martin boots are made by a doctor named Martin.

　　He accidentally broke his foot while skiing in the Alps. In the process of rehabilitation, in order to make his walking easier, Dr. Martin and his friends designed this kind of rough-looking but very comfortable boots.

　　It was Peter Townsend of The Who that brought Martin boots into the public eye.

　　He has an extreme paranoia about the way of wearing Martin boots—wrap the laces around the grooves of the soles and then wrap them around the calves, and roll the trousers to the calves, exposing the position of the laces.

Pete Townsend performed on stage wearing "Martin boots"

　　This way of wearing has aroused the resonance of young people who are keen on punk culture, and they have imitated this way of wearing. Martin boots have also changed from the original health shoes to one of the single products with the highest matching rate on the street.

　　Color bracelet

　　bracelet is today commonly used accessories, but its origin may we all think, from hippies. Hippies are young people who rebelled against social customs and politics in Western countries in the 1960s.

　　They have no declarations or leading figures, but use demonstrations and protests to express their opposition to nationalism and the Vietnam War.

　　They promote non-traditional religious culture and criticize the values ​​of the middle class in Western countries.

　　Because of the influence of religious culture, hippies wore rosary beads and became vegetarian. Their clothing influenced the local people's aesthetics. Gradually, everyone began to learn how to wear colorful bracelets. This style has also been used for reference by designers in major shows. Now, bracelets have become daily accessories.

Garter socks

　　This lady's personalized item was one of the must-haves for European men in the 17th century.

　　At that time, men liked to wear stockings, but because the socks would slide down, they would use a few straps to fix their shorts and stockings together, and garter stockings came into being.

　　After the 19th century, men began to wear long trousers. Although garter stockings fell out of favor among men, they have become a favorite of women.

　　In movies, more and more sexy actresses wear garter stockings, making them synonymous with sexiness.

Tuxedo

　　For formal occasions, a tuxedo is generally a standard for gentlemen.

　　The front of the dress is flush with the abdomen, and the back is to the knee joint.

　　The tuxedo originated in England and evolved from the cavalry uniform in the 18th century.

　　At that time, when the cavalry was riding a horse, the front and hem of the long clothes were rolled up, pinned to reveal the colorful lining, which looked very beautiful, which made other arms to follow suit.

　　In the middle of the 18th century, civilians and officials put on this short-cut cavalry costume, and the tuxedo was born and became popular in Britain and its colonies.

　　By the end of the 18th century, tuxedo had become a popular fashion in Europe and America.

　　This style has been imitated by gentlemen in many countries, and tuxedos have gradually become clothing for attending high-end occasions.

 　　D is an American friend of mine who can speak 4 foreign languages ​​and travels the world throughout his life. He is 86 years old this year. He used to be the coach of an Olympic sport and also brought out a world champion. He worked until he was 84 years old before he retired completely. He has a long and brilliant career. Although, he himself does not think so.

　　In terms of age, D is considered a healthy old man, he can walk without hindrance and can still drive. He has a generous pension. Before the epidemic, he can visit relatives and friends, listen to operas, watch movies, and go out of restaurants. Moreover, D's spiritual life is rich and profound. He loves reading, thinking, and has profound knowledge in literature, history and philosophy. But he thinks he has no contribution to mankind.

　　Now, he lives in a nursing home with fairly good conditions. He lives in a one-bedroom and two-living house, accompanied by a cat, and takes care of his daily diet and all kinds of chores.

　　Perhaps many people think that D's life is successful and happy, but D is very depressed mentally.

　　He suffers from severe insomnia and can only sleep for three to four hours for several days. He often has nightmares, can't sleep at night, and has bad energy during the day, and his diet and activities are affected. He also suffers from severe depression. He often stares at the wall motionlessly for several hours, not knowing the meaning of life, and often has suicidal thoughts.

　　In the past month, I had many in-depth conversations with him. I found that most of D’s pain is related to this specific age group and has a universality beyond culture. Longevity is the desire of many people. However, even for people like D, old age is not so easy. It is worth paying attention to children and carers who care about the mental health and happiness of the elderly. As Atu Gwende, author of "The Best Farewell," said, old age is a series of loss and decline.

　　D’s wife has been dead for many years. Five years ago, his proud son died of cancer. A person who lives longer than his partner and children will inevitably suffer the pain of bereavement. His wife suffered from Alzheimer's disease in his later years. In the last few years, D had to send her to a nursing home because she could not take care of it. Since her death, D often feels that he has not fulfilled his responsibilities, and guilt and regret haunt him like a poisonous snake. Especially recently, he feels memory decline, often forgetting things, thinking that he might also become a patient with Alzheimer's disease, and his wife's state before the end of life, he feels panicked and anxious.

　　Although the conditions of the nursing home are good, D has never accepted the life here. Like many elderly people, he feels that he is "waiting for death" when he arrives in a nursing home. This place is full of elderly people sitting in wheelchairs, and people die every month, and the atmosphere is depressing. He refuses to think that he belongs here, keeps a distance from those around him, and has not made a friend for many years.

　　Despair and sense of meaninglessness clouded D's mind. He felt that he had no contribution to society. He was a little excited only when he talked about his previous career, but, he said, it was just passing by. Someone continues to do his work, and others do well, or even better. He lamented that once he died, no one would remember him within two months.

　　As Catherine Mannix, the author of "Farewell" and a British palliative medicine expert who accompanied thousands of dead, said, fear of being forgotten is a universal anxiety at the end of life, and it is natural to want to leave a legacy. . Martin Seligman, the founder of positive psychology, discovered that depression is related to negativity and helplessness. Taking action and doing constructive and meaningful things can help resist emptiness, boredom, and get rid of depression.

　　Fortunately, sympathetic, non-judgmental listening creates a safe space. After D confided his distress and anxiety, he realized that some of the problems he faced could only accept, and some could only let go. He ate three meals a day on time, increased exercise and social interaction, set a schedule for work and rest, and learned to meditate. I re-evaluated my past experience with an objective eye, seeing my own success, and forgiving and accepting my own shortcomings.

　　D decided to create and record the history, anecdotes and insights of the sport he participated in for more than half a century. This idea excites him.

 On a midsummer night, let yourself travel through time and space, return to the forest of ancient Greece, transform into a light firefly, use the flickering light to guide the elves, and start a fantasy journey. This is not an illusory dream that is divorced from reality, but a visual feast of the "Midsummer Night's Dream" that the world-renowned Royal Shakespeare Company will bring to audiences around the world from March 12th.

This new play called "Dream", inspired by Shakespeare's classic play "A Midsummer Night's Dream", moved the story from the theater stage closed due to the new crown epidemic to a virtual platform supported by the Internet, and brought virtual reality to the same level. Technology is used in the background narration of Shakespeare's classic plays. The audience can not only wander in the virtual Midsummer Night Forest, but also interact with the actors in real time and influence the development of the plot.

Even the imaginative Shakespeare himself, I am afraid that the handed down classics he created can be presented by posterity in this way.

"Brave New World"

The Royal Shakespeare Company has received special financial support from the "British National Research and Innovation", and has cooperated with the Manchester International Arts Festival, the London Philharmonic Orchestra, the world's leading virtual reality technology company "Marshmallow Laser Monster" and the famous online The game company "Epic Games" has worked hand in hand to push the "immersive theater", an innovative form of expression that completely breaks the boundaries between the stage and the audience, allows the audience to participate in the plot and becomes a part of the story, to new limits.

The play brings together outstanding talents in stage performance, music, video and game production, and scientific research. They use their respective expertise to use immersive live performances through multiple platforms, using virtual reality (VR), augmented reality (AR), and hybrids. High-tech technologies such as MR, bring a brand new and upgraded experience to the audience. As an interdisciplinary experiment of the "Future Audience Group" in the UK, the audience not only breaks through the geographical limitations of watching dramas, instead of passively watching, but actively participating in the development of the plot and becoming a part of the entire drama.

The seven actors in the studio use movement to control the avatars in the play. At the beginning of the show, an actor invited the audience from reality to the virtual midsummer night forest; under the densely clouded dusk, the audience instantly turned into fireflies in the forest, shining and gathering with little glimmers, lighting up the midsummer night The forest, and the avatars controlled by the actor at this time, such as Elf Parker, spider webs, and moths, follow the guidance of these fireflies, constantly shuttle through the forest, and experience the need to save the forest in the storm and break the spell before dawn Fantasy journey.

The role of fireflies the audience assumes is very important. They not only participate in the performance, but also guide the virtual characters forward. The fireflies played by different audiences have different choices for the direction of travel, which causes Parker the elf and other virtual characters in the play to have different trajectories and directions of travel.

The music recorded in advance by the London Philharmonic Orchestra is combined with Gestrument, the most breakthrough interactive music tool. The virtual characters will produce different musical effects in different directions and trajectories, which makes this experimental play bring audiences A dual interaction of vision and hearing.

It can be said that this 50-minute online performance is a shared experience between the online audience and the seven actors who play Parker and other roles. Each performance of "Dream" is a unique performance due to the participation and guidance of different audiences.

Global online audiences can choose to watch the performance for free, or they can choose to purchase a special ticket of £10 to participate in the above-mentioned interaction with the actors. Such experiential audiences can also enter the theater in person to watch a play, learn about the background of the story and how to interact with the actors in the virtual "theater hall" before the opening, participate in the performance during the performance and directly influence the actors at key moments in the play In the world, after the performance, you can also meet with the actors and learn about the backstage story of the theater.

In 2016, in the live stage of Shakespeare's classic play "The Tempest", high-tech was used for the first time to bring virtual characters onto the stage. This time, these technologies are fully blooming in the experimental drama "Dream". In this regard, the excitement of Gregory Doran, the artistic director of the Royal Shakespeare Company, is beyond words. He said, “This is a new interpretation and imagination of Shakespeare’s classics in the 21st century. It has given us a new context of imagination. It’s really extraordinary! I want to quote a sentence from the play-this will be a brave new one. world."

"The show must continue"

After the spread of the new crown virus worldwide in 2020, the stage for live performances has been forced to close. With the continuous recurrence of the epidemic in the West, theatrical stage performances have encountered unprecedented survival dilemmas.

At the recent Oxford University Business School Entrepreneur Global Online Forum, there was a seminar entitled "Performance Must Continue", focusing on the difficult live stage performing arts industry.

There are three major theaters in the UK that enjoy special royal funding. The directors of two of the theaters are Lisa Burger, executive director of the National Theatre of England, and Catherine Mallyon, executive director of the Royal Shakespeare Company. Participated in this seminar as a special guest.

About 70% of the employees in the British drama industry are freelancers. Lisa Berg is worried that once the epidemic is over, these people may not all return to the industry. This kind of brain drain will undoubtedly be a huge blow to the drama industry.

Even if live theater performances can be reopened in the future, the social distancing measures required to control the virus will result in a sharp drop in the number of live audiences. This has to make the theater an economic account: Will live performances requiring social distancing measures Can’t make ends meet because the box office revenue cannot make up for the cost of the performance? Catherine Malion mentioned that the business model of the entire industry needs to be rethinked and defined. This is not only an innovation in story content and production technology, but also a new thinking and breakthrough in the business model.

High-tech methods are having a huge impact on theatrical performances. In the early days, high-tech was regarded as an unpopular "other" by the theater industry. However, as time went by, more and more theater stages took the initiative to incorporate high-tech into stage performances and related industries.

The new crown epidemic has accelerated this reshaping process. During the epidemic, the British theater industry began various cooperation with high-tech industries. Some theaters use advanced high-definition video technology to record live performances of dramas and broadcast them on TV and online platforms; some theaters use online platforms to interact with audiences. For example, in the interpretation of Arthur Conan Doyle’s classic "Holmes" series, the audience who enters the online platform will play the role of jurors, which will affect the development of the plot and become a part of the whole drama; while some theaters pay tribute to the classics, for example, Drama actors used the online platform to read Shakespeare's sonnets live online, comforting everyone who felt lonely during the epidemic lockdown.

One of the most influential attempts is the "National Theatre at Home" online program launched by the British National Theatre. According to statistics, during the four months from the start of the free program in April 2020 to the end of July of that year, a total of national theater performances including Shakespeare’s "Twelfth Night" and Charlotte Bronte’s "Jane 16 classic plays, including Love and Tennessee Williams’ Streetcar Named Desire, have been viewed more than 15 million times by 9 million families in 173 countries.

However, the popularization of theatrical arts and the economic benefits of theatrical institutions must be balanced. The free "National Theater at Home" online program cannot be sustained for a long time only with some symbolic fundraising. Therefore, after the show’s global success, the National Theatre of the United Kingdom launched the "National Theatre at Home" online theater for paid users, ensuring that users can not only move the theater back home, but also watch the theater’s new plays and exclusive behind-the-scenes monthly story.

Catherine Malion mentioned at the seminar that live stage performances will never return to the single form of the past. Instant performances and productions based on immersive performances, as well as diversified mixed expressions, give more The audience brings a new experience, which is the industry trend she sees. Many practitioners in the theater industry are becoming more and more calm about the subversion and redefinition of the theater industry by high technology.

Gregory Doran, the artistic director of the Royal Shakespeare Company, believes that online performance cannot replace the theater itself, but high-tech has brought more possibilities to the theater stage. “Online audiences can influence the performance and plot development of actors no matter where they are. This is very exciting. But this cannot replace the live stage performances where the audience and the actors are in the same space, but only provide another possibility. Sex." He said, "Shakespeare is the best storyteller. It is a great experience to have the opportunity to use Shakespeare's plays to explore the possibility of future theater performances!

The Principality of Monaco (Principauté de Monaco), referred to as Monaco (Monaco). Speaking of this country, perhaps the first person to come to mind is the majestic Princess Grace Kelly (Grace Kelly). Some people often confuse it with Morocco, a North African country.

The Palaisprincier de Monaco (Palaisprincier de Monaco), built in the 13th century, is located on the edge of a cliff and is the seat of the Monaco government. Princess Grace, who brought glory and legend to Monaco, once lived here. Today's Royal Palace of Monaco is half of the royal family's private residences and offices, and the other half is a museum. I have seen the magnificent palace buildings of other European countries. The pale yellow palace of Monaco does not feel luxurious and magnificent, because the palace with its unique location was originally a military fortress and served for military purposes until the 17th century. The forts cast in the Louis XIV period are displayed around the Palace Square, which seems to be a silent account of history. Standing on the northeast side of the square, you can enjoy the scenery of Monte Carlo Port. Every day at 11:55 noon, there is a changing of guard ceremony in the square. The guards with focused and serious expressions performed a series of ritual actions in an orderly manner in the marches played by the band, accompanied by the rhythmic slogans of the captain of the guards. This is one of the items that tourists love to watch when visiting Monaco.

The luxurious Grand Casino of Monte Carlo

As one of the four largest casinos in the world, the Casino de Monte-carlo (Casino de Monte-carlo) is a landmark of the Principality of Monaco. It has a history of more than 100 years. Louis Charles Garnier), the world-famous Opéra de Paris (Opéra de Paris, also known as Opéra Garnier) is also his work. The "trench" of Monaco can be seen here. The whole building is extremely luxurious like a palace, beautiful reliefs and portraits are scattered in various game halls, gorgeous and bright crystal lights make the hall bright as daylight, and every corner is meticulously carved. A dazzling array of luxury shops, luxury hotels, top hotel clubs...the luxury cars at the entrance of the casino are also a dazzling sight. In this situation, the cognition of "wealthy" has been completely refreshed. If you don't have the arrogance and confidence to spend a lot of money, think twice carefully before going to the gambling game. According to local laws in Monaco, nationals are prohibited from entering Monte Carlo for gambling, but tourists are welcome. Ordinary tourists over 21 years of age can buy tickets to enter the casino, but they must dress neatly, and they need to wear formal attire at night.

The world-famous Oceanographic Museum of Monaco

The Monaco Oceanographic Museum (Musée Océanographique de Monaco), opened in 1910, is the world's first oceanographic museum. The museum with the back of the mountain facing the sea, the front of the gate and above the lintel are carved with images of mermaid princesses, sea gods, sea animals and turtles. From decoration to arrangement, every scene touches the heart to remind people of the wonderful ocean world. The Oceanographic Museum benefited from the founder of the sea, Prince Albert I of Monaco, who used the large amount of income derived from the franchise to open a casino for marine scientific research. The prince devoted most of his life to marine research, and was therefore known as the founder of marine science. The museum and the basement have 5 floors. It has the richest marine collection in the world. There are more than 6000 kinds of marine life for visitors to enjoy, from the aquarium to the series of natural history exhibits, from the shark hall to the turtle island on the panoramic terrace. This rich museum provides the world with a unique opportunity to learn how to recognize, love and protect the ocean. This unique experience not only satisfies tourists' curiosity about the mysterious ocean, but also the rich ocean knowledge that draws people's attention to the issue of the ocean. The protection of natural ecological creatures is closely related to each of us. The individual is a drop of water in the ocean, and the ocean is made up of every drop of water.

The "Pearl in F1 Crown" Monaco Circuit

Circute de Monaco (Circute de Monaco), also known as Monte Carlo. I think racing fans should already be familiar with this track, which enjoys the reputation of "the crown jewel of F1". This street-shaped circuit, which is surrounded by Monte Carlo and Condamin districts, is one of the four most famous circuits in the world. It is as famous as Indianapolis in the United States, Le Mans in France and Newburgh Green in Germany. Monte Carlo is also the shortest track in F1, and is especially famous for having the slowest corners and a tunnel in F1. Because of its combination with the street, the track is very narrow and the difficulty is the most difficult in the world. Driver Nelson Piquet once said: “Driving an F1 car on the Monte Carlo circuit is as difficult as driving a helicopter in the living room. A small mistake may cause the car to crash into the guardrail and stop work early.” In this way, winning at the most challenging circuit in Monte Carlo is also a strong proof of the skills of the racers. On this short track, countless brilliance and legends have been born. What is committed to moving forward in the limited is the eternal desire to transcend life.

 　　Does anyone around you use branded phones such as Duowei and Tianyu?

　　At the beginning of May, a familiar "bargaining" was underway in a live broadcast room with 25 million fans.

　　"Go!" In the voice of the staff requesting the link, the "manufacturer representative" from Duowei X7 was anxious, and firmly said that he couldn't do it, constantly emphasizing the manufacturer's leading pricing power.

　　"Did I make 500 yuan for you (the manufacturer)?" The anchor countered the "manufacturer representative" in a higher tone, refusing to increase the subsidy to 1,000 yuan.

　　The helpless "manufacturer representative" finally "gave up" and agreed to provide a subsidy of 500 yuan, and the price dropped "in place".

　　In this live broadcast room watched by 200,000 people, after some bargaining of "you come and go", the atmosphere was set off to the climax, and the appetite of the audience was dampened. The anchor immediately revealed the final price: "Double A 5G mobile phone, 1499 yuan, you can’t get it anywhere.” In the

　　fast-hand live broadcast, the “bargaining” plot is old-fashioned, and sales prove that this “performance” still works, even if it’s placed in a “ "Overdue" on the mobile phone brand for many years.

　　According to the data provided by Feigua platform, in the past 30 days, in addition to Duowei, the anchor has sold 5 non-mainstream mobile phone brands such as Tianyu, Coolpad, and ZTE. The Duowei brand has the most live broadcasts, with a total of 9 live broadcasts. Product, X7 this model is exposed the most.

470 million yuan in 30 days

　　Some mobile phone brands that have been popular in the era of feature phones have not completely disappeared, and even launched 5G models following the trend.

　　Compared with the first-tier mobile phone brands, they have no celebrity endorsements, no large-scale new product launches, and it is difficult to see the mainstream supermarkets, but they have found a new living space in the live broadcast room of the anchor.

　　"What is the equivalent of a 5G mobile phone? It is equivalent to 10 times that of a 4G mobile phone."

　　"An 8-core (processor) mobile phone, let me tell you, usually we are on a high-speed (driving) 2 runways, (will) traffic jam. 8 Runway, I feel comfortable walking.”

　　Such as the comparison of 10x speed and the analogy of “high-speed track”, it can be seen that the anchor has spent a lot of time in promoting this phone. The “manufacturer representative” and the live broadcast staff, Take turns in battle. In the live broadcast room measured in seconds, it took more than half an hour to introduce a product alone.

　　The effect is immediate. According to Feigua data, in a live broadcast, the estimated sales volume of Dove X7 is as high as 12,000 units, and the estimated sales amount is about 17 million yuan. According to incomplete statistics, in the past month, Dove 7X has broadcast live 8 times, with a total estimated sales of over 95 million yuan. With the addition of the four brands of Candy, Tianyu, Coolpad, and ZTE, the estimated sales of mobile phones that the anchor carries are more than 470 million yuan.

　　In the fierce competition in the smartphone market, these brands are in a very awkward position. Compared with other brands and counterfeit brands, their origins are "regular", but they are far inferior to major manufacturers in terms of R&D and capital investment. Most of them "imitate" the appearance of mainstream brands. On the road of design and naming, we are struggling to survive.

　　"It's not a miscellaneous brand, it has a little popularity. It used to be very popular, just like a celebrity. Some people still know it when going out." Li Sheng, the owner of a mobile phone offline store in Zhongshan City for more than 10 years, told "21CBR" Reporter, the main market of Coolpad and other brands has been put overseas.

　　Offline, non-mainstream mobile phone brands such as Duowei and Tianyu are almost hard to see. Their main channels are online sales.

　　At present, the brand effect of offline sales channels is relatively strong. Because of after-sales and other factors, few dealers sell mobile phones of non-mainstream brands. The mobile phone store where Li Sheng is located mainly sells mainstream brands such as OPPO, vivo, and Apple.

　　The current hot live broadcast e-commerce has become the best channel for these outdated mobile phone brands to create a new sales miracle.

Secret good business

　　Relevant data shows that the current scale of online live broadcast users in my country has reached 617 million, of which e-commerce live broadcast users have reached 388 million.

　　According to data from KPMG and Ali Research Institute, it is estimated that the total scale of live e-commerce in 2021 will be close to 2 trillion yuan (1995 billion yuan). In addition, Guosheng Securities predicts that the industry market size can grow to 6 trillion yuan in 2025.

　　As the fast hand of the leading live broadcast e-commerce platform, bet on "private domain traffic", that is, the platform anchor's own traffic. These Kuaishou anchors with tens of millions of fans can also reap huge sales by relying on their followers.

　　Kuaishou official data shows that last year, the penetration rate of private domain traffic remained above 70%. On average, each user spent more than 20 minutes on the follow page, accounting for about a quarter of the overall consumption time. This kind of private domain penetration rate and consumption time contributed more than 70% of the interaction and comments between videos and live broadcasts, more than 80% of the revenue from live broadcasts, and more than 70% of e-commerce GMV.

　　The platform characteristics of private domain traffic have created Kuaishou's "trusted e-commerce". However, in a closed environment dominated by anchors and loyal fans, fan users are also susceptible to be confused and difficult to distinguish.

　　Especially the “sinking market” users on the Kuaishou platform are not very proficient in e-commerce routines. According to the "2020 Kuaishou E-commerce Ecological Report", the second-tier and below consumer groups account for 87% of orders.

　　These user groups have contributed to the rapid growth of sales for big anchors and big platforms. The Kuaishou financial report shows that the total e-commerce transactions in the first quarter of 2021 increased by 219.8% year-on-year to 118.6 billion yuan; the revenue of other services (including e-commerce) was 1.2 billion yuan, an increase of 589.1% year-on-year. The

　　live broadcast e-commerce ecosystem is prosperous and directly Drive the rapid growth of platform advertising revenue. In the first quarter, online marketing services revenue was 8.6 billion yuan, a year-on-year increase of 161.5%, and accounted for more than 50% of total revenue for the first time.

　　Kuaishou CEO Su Hua once said that about 20% of advertising revenue comes from two advertising products, Xiaodiantong and Fan Toutiao. And these two products are mainly aimed at anchors and merchants with goods. Therefore, for e-commerce anchors, Kuaishou has launched various policy support.

　　According to the observation of a reporter from "21CBR", the total sales of these fast-hand anchors, which cost nearly 1,000 yuan, once ranked first in the entire platform.

　　The reason why the anchor is working hard to sell out-of-the-box mobile phones is that the benefits are far greater than the brand products.

　　The dealer sells a 2,000-yuan branded mobile phone, and gets a share of only 200 yuan. Selling non-mainstream mobile phone brands has higher profits. A mobile phone priced at 1,499 yuan may only cost a few hundred yuan.

　　The low commission for branded mobile phones is based on the manufacturer's performance upgrades and celebrity endorsements to create influence, which makes users more aware and easier to sell.

　　According to the report data released by the market research organization Canalys, in the first quarter of 2021, mainstream mobile phones such as vivo, OPPO, and Huawei accounted for 89% of the market share, while other brands shared only 11% of the remaining market share. The first quarter shipments were 980 Million units.

　　Outside the blockade of mainstream brands, how do outdated mobile phone brands capture the old iron in the live broadcast room? In addition to consuming the fame of the past and playing the card of affection, the killer is the so-called "low price", and the service with a vain reputation.

　　Take Dove X7 as an example. It’s hard to see the relevant page introduction on Dove’s official website. In Dove’s Tmall flagship store, the price of this product is 4999 yuan, and the monthly sales order is 1.

　　In a mobile phone franchise store on the JD platform, Dove X7 is also priced at 4,999 yuan, with one product evaluation. This shop mainly sells Duowei and candy, which is almost the same as the mobile phone products that the above-mentioned anchor has recently promoted. The product introduction page shows that its time to market is October 2020, the sales cycle is more than half a year, and the intention of product inventory clearance is obvious.

Many sales routines

　　"As soon as I get home, I will get a mobile phone for three or four thousand dollars. Today, I will let you take it down at 1499... It (the manufacturer) has been squeezed by us and has no profit. Even if it is picked up today

　　, it will be picked up." The mobile phone displayed the sales page of the e-commerce platform, and proved to the old iron: it is "really" worth three or four thousand yuan, and we beat the price down. In fact, the role of these display shops is more like a "childcare".

　　This is also a tacit routine. Li Sheng said that some dealers will open a store on JD.com and mark a high price as a reference price. Then use the brand influence of JD.com and Taobao to convince consumers who are not familiar with e-commerce. Look, these platforms (actually third-party stores that no one cares about) sell for such high prices. I sell them cheaply. The so-called "cheaper" supply.

　　The candy phone M40Pro, which looks exactly like Huawei's flagship model, also operates in the same way.

　　On April 17th, an anchor broadcasted this product live. The price of the live broadcast room was 959 yuan, and the store price was 4999 yuan. On April 24, a user left a message at the Taobao store selling the product, saying that "a mobile phone less than 1,000 yuan". The "21CBR" reporter found from the historical price website that the lowest historical price of the candy M40pro was only 789 yuan, which was even nearly 200 yuan lower than the price in the live broadcast room.

Smartphone shipments and annual growth rate in mainland China

　　Paradoxically, whether it is the official Tmall candy store or this specialty store, the price will increase when they sell it by appointment. The anchor will not tell the "family" in the live broadcast room that the displayed price is after the price increase.

　　Someone replied below the review, and the price of the product suddenly rose to 4,000 yuan. "Because of the long (live) live show." Another netizen explained in the comment area.

　　However, Lao Tie, who is not familiar with e-commerce platforms such as Taobao and Pinduoduo, finds it difficult to know such a routine. The information they obtained is that the price of the same product in the live broadcast room is lower than that of Taobao and JD.com.

　　As of press time, the price of Dove X7 and candy phone M40Pro on these platforms is still 4999 yuan. In order to prevent consumers from "seeing through" the routine, this price is likely to last for a while.

　　"You placed an order in our live broadcast room. If you go home, you won’t be worth two or three thousand dollars. You will return it to me." The anchor vowed to return the goods without any reason within 15 days. At the same time, he emphasized the "three-year national warranty". Like returns without reason, they are all special "extra value" services provided by the anchor.

　　Fans may have not considered after paying for the low price. These outdated mobile phone brands have few offline sales outlets, and after-sales and repair shops are even rarer.

　　The reporter of "21CBR" inquired about the two mobile phone products Duowei and Candies promoted by the anchor. The after-sales service phone number on the official website of Duowei mobile phone can be connected, but no one answered; the after-sales customer service number starting with 400 marked on the official website of Candy mobile phone, Shown as a blank number.

　　Even if the manufacturer has the ability to guarantee the quality, according to consumers' usage habits, the life cycle of a mobile phone is usually less than three years. The so-called three-year guarantee is more like a blank check for users.

　　"Warranty, he said, 10 years are okay. The premise of implementing the warranty is that you need to use it for that long. Now a mobile phone is mostly used for less than three years. He said that this number is just to attract attention and has no implementation significance."

　　Even the mobile phone product itself has problems. According to the evaluation video of the digital blogger "Science and Technology Xiaoxin", he bought a Dove mobile phone in the live broadcast room of the broadcaster. After checking the mobile phone's network license, he found that the Dove mobile phone was inconsistent with the registered model on the website of the Ministry of Industry and Information Technology. To put it bluntly, it is "a copycat machine."

　　The report released by the Black Cat complaint shows that in the live e-commerce consumer complaints in 2020, false publicity has become the main cause of complaints, and the number of complaints involved far exceeds other complaints.

　　Regarding the chaos in the live broadcast industry, the policy level is also increasing supervision. The "Administrative Measures for Web Live Marketing (Trial)" stated that live broadcast room operators and live broadcast marketers must not "publish false or misleading information, deceive or mislead users; marketing counterfeit and shoddy, infringing intellectual property rights or not complying with the protection of personal, Commodities subject to property safety requirements".
