Marshal Chen Yi’s poem “Things will change when they reach the end” is about the issue of moderation. People’s life, all the time, dealing with the degree, such as behavior norms, into and out of the appropriate; for people in the world, the proportion; grasp things, the appropriate. In a sense, a wonderful life is often the result of the appropriate size of the degree of grasp; a gray life is the degree of the fire to grasp the bad results. We might as well observe some daily life. The old ancestors have said, “the people to food for the day”, whether rich or poor, men and women, as long as they live, they have to eat. Eat less, will be hungry; eat more, and will be propped up. Therefore, there is a proverb: “eat seven minutes full, disease will not find”. The so-called “seven portions full”, is to eat moderately. Diet is too poor, yellow muscle thin; eat too well, full of brain fat. Difficult times, eating bran and swallowing vegetables, not to mention meat and vegetables, a little tofu and cabbage even if to improve life, long-term filling of the stomach, people’s faces are vegetable-colored, which is malnutrition. Now the standard of living has improved, some people tonton meat, wine every day, eat and drink, without restraint, “alarm” also sounded, high blood fat, diabetes, fatty liver, etc., a large number of “rich disease” swarmed over, which is over-nutrition. You see, not enough to eat is not good, eat too much is not good. Enough and not enough, too much and not, is the degree. Li Junxia, Department of Gastroenterology, Peking University First Hospital, Beijing, China The ability to live in moderation is not only a health issue, but also reflects the moral concept. As the ancient saying goes, “Wealth and wealth cannot be lusted after, and poverty cannot be shifted”. Whether for the sake of the country or for ourselves, we should be proud of hard work and ashamed of pride and luxury. We often see this phenomenon: those who have a light meal are happy and joyful, those who are dressed in gold and mink fur are in a trance; those who have a simple house and a humble room are happy and harmonious, those who have a luxurious villa are full of sorrow; those who take a step as a car are healthy and healthy, those who take a step as a car are ill and sick. Since the ancient times, the cold family out of filial son, never playboy less great man. The reasoning within is self-explanatory. This is not to say that people should not pursue a rich life, who does not know rich days than poor days? The problem is that the enjoyment should be moderate, more than the degree, it will go the other way. Living a rich life should be scientific, scientific in order to be happy. Ignorance and ignorance, the rich days will also become miserable days. People are social people, always have to communicate with others, always have to talk and do things, which requires more control of the degree. The value of the “qu” is the same as that of the “s”! Do not think aggressive, lazy, three days to fish, two days to sunbathe, can only achieve nothing; competitive, do not understand the way of literature and martial arts, a relaxation, will not work and rest, exhausted body, will only want to speed is not achieved. The goal is too low, a little into that stop, a small fortune is safe, easy to meet, no motivation, inevitably mediocre, can not achieve great things; the goal is too high, daunted by the hope, efforts are difficult to reach, and will lose confidence, it is difficult to achieve the cause. No rules and regulations will be a mess, follow the rules is rigid and mechanical. There are always two sides to the story, life is full of dialectics. The degree of grasp of the degree is a sign of a person’s maturity. Mature, mannerisms have degrees; immature, words and actions out of order. This is the important reason why some people have a smooth sailing, brilliant life, while some people hit the wall, life is difficult.
