McKinsey & Company has an interview question: Are there more gates at the entrance of the subway, or more gates at the exit? Theoretically, as many people come in as there are people going out of a subway station, there should be the same number of turnstiles. But the reality is that there are many gates for export. why? 　　On the one hand, you can regard the subway station as a closed space, and the speed of evacuation is definitely more important than the speed of entry. Because evacuation is directly about safety, access is only about efficiency. Safety takes priority over efficiency. 　　There is another reason: the flow of people at the entrance comes one after another, just fluctuating smoothly. But the flow of people at the exit, as a car arrives at the station, is a surge, and the flow of people will increase in an instant, so there should be more exit gates. 　　This is the continuous revision of the theoretical world by the real world. I think there must be the same num...

 　　There are a large number of bacteria living in the human intestinal tract, and the total number can reach more than 10 times the total number of human cells. Most of them are normal members of the gut environment, the "good bacteria". However, the intestinal tract is sometimes infected by pathogenic bacteria, causing various symptoms such as abdominal pain, diarrhea, and blood in the stool. These pathogenic bacteria are "bad bacteria". So what is the relationship between "good bacteria" and "bad bacteria"? 　　The intestinal tract is also an "ecosystem" 　　In fact, the relationship between "good bacteria" and "bad bacteria" is not static, and in some circumstances, normal members of the intestinal tract can also cause disease. In other words, "good bacteria" may also become "bad bacteria" under certain conditions. In short, the relationship between gut flora and the human body is very complex. An ...

　　Over the past ten years, I have interviewed many people, and found that many people can't write resumes, and they will be rejected before the interview. 　　It is not difficult to say, there is only one key point: think that you are not waiting for the other party to judge, but use your resume to give the other party a reason to interview you. 　　First of all, the "personal profile" should not list a bunch of basic information such as work skills and educational experience. The opening chapter should be high-energy: why choose you and not others? You can directly write what core advantages you have compared with your peers. For example, you have written many official account articles with 100,000+ views, and you are particularly good at following hot spots; another example, your advantage is strong empathy, especially insight into the emotions of audiences, users, and Party A. 　　Secondly, "self-evaluation" such as "eager to learn" and "able to endu...

 　　The two international news at the beginning and end of October are really tragic: 　　On an ordinary Saturday night on October 1, a serious stampede occurred after a fierce ball game at the Kanjuruhan Stadium in Malang, East Java, Indonesia The incident caused 135 deaths and about 580 injuries; on the evening of October 29, a stampede occurred at the Halloween celebration in Itaewon, Seoul, South Korea, resulting in 156 deaths and 157 injuries, at least 30 of whom were seriously injured. 　　If the stampede in Itaewon is a bit of a "natural disaster": the narrow ramp, the excess crowd that has just lifted the epidemic restrictions, and the crowds caused by the delay in news, then the stampede on the flat court in Indonesia is more It is more inclined to "man-made disasters"-extremely angry fans, police who violated regulations, and mistakes in evacuation settings... 　　Looking back at the stadium riots in Indonesia that caused heavy casualties, we will find that even ...

 Then one of the following days Opula gave an explanation of the whole complicated matter which, besides being clearly understandable, was so contrary to all my beliefs and knowledge that it took me a long time to come to my senses, at least as much as it takes to organize one's thoughts. My mistress was visiting bullock colonies being built and allowed me to accompany her. In the flickering, green light, a whole row of Babel towers under construction swayed precariously - the work of masses of stubbornly and tirelessly working bulls of the Capillaria headquarters of its new suburb : individually-105- each of them is being made a sky-scraping ladder, so many attempts of a single thought to reach the surface of the sea at the bottom of which these unhappy worms work, fight and perish, forgetting again that they can never reach their goal. We also went inside one of the towers: my mistress expertly looked around and declared that this building, from the point of view of the oihás , w...

 　　The sound of "bang" is a good childhood memory of many born in the 70s and 80s. 　　I saw the master popcorn seller put the baked "black gourd" into a sack and step on it. Then, with an astonishing "bang", a burst of white mist rose, and the golden corn kernels turned into fragrant popcorn. 　　Corn has opened the golden childhood of Chinese people. It is so commonplace that corn, one of the four major staple foods in my country, is actually a fresh "back wave" on the Chinese dinner table. 　　A generation behind waves pushes forward waves. Corn is already one of the most widely planted crops in the world, with an overall output of about 1.134 billion tons in more than 170 countries and regions around the world. In China alone, the total corn consumption in 2021 will be about 290 million tons. 　　In the live broadcast room of the big V "Oriental Selection", a corn is 6 yuan, and 120,000 corns are sold in 10 minutes, which has attracted wide...

 　　One of the more common pains in interpersonal relationships is that the other party does not understand them, so they feel wronged and angry. 　　Some people are eager to meet someone who can understand themselves. Their idea is: I don't require the other party to have a house or a car, I just hope to meet someone who understands me. This is said as if understanding you is easier than owning a house and a car. 　　I have read a beautiful article called "It would be great if you understood me", which wrote: 　　Everyone has a blind spot, which 　　they cannot get out of, and 　　others cannot break into. 　　I put deep secrets there. 　　You don't understand me, I don't blame you. 　　It feels like a mistake for others not to understand you, even to the point of "I don't blame you". This article was very popular at the time, because it expressed the real needs of many people: If you understand me, it would be great. 　　To be understood is the deepest expectation of...

 　　After reading the preface to Feng Zikai's painting collection written by Venerable Xia Mian, I was very interested in the details of Master Hongyi's life. The mage lived in a small hotel, and Xia Shi knew it was very refreshing, but the mage seriously argued like a child, "there are not many bedbugs, but two or three." The new ones are about the same. The radishes and cabbage that I eat are almost like "changing color and making a feast"; if the vegetables are too salty, I feel good, "Salty also tastes salty." There is nothing bad in the world. Master Xia said with emotion: "I almost shed tears of joy and shame when I saw the amazing expression of him solemnly picking up a piece of radish with his chopsticks." He was 　　deeply touched. Don't look down on things, and be full of affection for everything around you. The countryside used to be more like a natural life, the treasure of the poor, and the practice of the rich. The mage is ...

 　　Eyes are "windows to the soul". I don't need to say much about the exquisiteness and complexity of this organ. 　　However, in this article, I want to complain: the human eye is actually not well designed. The lens is easily deformed, which makes us nearsighted or farsighted, let alone. Even eyes with perfect vision have one major defect - the blind spot. What are blind spots? 　　A blind spot is an area of ​​vision that is almost in front of us, but which we "blind" to see. 　　There is a simple way to know where your blind spot is: close one eye and look at a word on a piece of paper with the other. Move the word left and right, when it disappears, it means it has moved into your blind spot; if you move it again, it reappears, it means it has moved out of your blind spot. 　　Why do we leave such a "dead angle" in our field of vision? To understand this, one needs to know how the eye works. Think of our eyes as a room with only one small window. In the ro...

 　　Ma Long once made a coffin with his own hands, and spent a month with it day and night. 　　During the day, he sat and worked inside, surrounded by red hijabs, red lanterns, and "human tissue" that had just been painted. At night, he propped up a retractable bed and slept in the ancestral hall next door—the room was not big, but there was a Bodhisattva. 　　This house is one of Ma Long's works. As a secret room designer, he has personally created Chinese-style secret rooms, dark-style European-style castles, and mutants who have experienced nuclear radiation. It is normal for Malone to be active in a room with a weird atmosphere, and he even has to think about how to make this atmosphere stronger. 　　When he just graduated from architecture four years ago, Ma Long spent every day on the construction site and in the office, living a repetitive life. At that time, he did not expect that one day, he would leave the wind and sun on the construction site, walk into a small room,...
