Confucius said: A gentleman has three precepts. When you are young, your blood energy is not stable, and you should be careful about appearance; when you are strong, your blood energy is strong, and you should be careful about fighting; when you are old, your blood energy has declined, and you should be careful about gaining.

These are familiar to all of us. Confucius divided life into three stages and was very careful with others. When we add age, experience, psychological and physical experience, we will understand the profound meaning of these three sentences. The most important thing to be careful about in youth is sex. If there is excessive greed between men and women, many people's bodies will be destroyed when they are only in their thirties or forties. There are many diseases in middle-aged and elderly people, which are caused by sexual behavior in youth without "preventing oneself from sex." The Chinese have studied the knowledge of "sex" very carefully. This is in terms of medicine. However, it is very pitiful that they have shielded this aspect too much from a moral point of view. On the contrary, this knowledge cannot be developed and the national health is affected. be hindered. As far as I know, in the past, there was almost no teenager in primary and secondary schools who did not commit masturbation. Parents, beware! During the Nazi era in Germany, teenagers wore shorts and tied their hands outside the quilt when sleeping at night. This was about hygiene and for the superiority of the Germanic nation. Although this approach is excessive, it is of great educational benefit. Nowadays, the thinking of the younger generation is that girls are willing to marry rich old people. If their husbands die, they will remarry if they have money anyway; boys are influenced by certain foreign movies and like to fall in love with middle-aged women. This is a general trend and a serious problem. So after understanding the thoughts of young people, we found that there are many problems in our education. As for young men and women in foreign countries, such as the United States, they are very reluctant to get married. They are afraid that they will be responsible after getting married, and it is just for fun, causing social chaos. This is a big problem in human culture, so Confucius said: "The blood is not yet determined, and the guard against sex is sex." When this sentence really comes into play, there are many problems, and special attention must be paid to sexual psychology education.

The most important thing to avoid in the prime of life is fighting. This fighting is also a big problem. It doesn’t just refer to fighting. All spirited competitions are fighting. It is said here that the warning is fighting, which is career competition. You want to hit others at every turn until you can stand up. This mentality is a problem among middle-aged people.

Elderly people should be careful. This problem is quite serious. People who are younger than this age don’t know about it. For example, if a person's personality is quite generous, he should always be vigilant to avoid being unable to do so when he gets old. I have seen many people who were generous and generous when they were young, but when they are old, they are reluctant to spend even a dime, and they are reluctant to let go of their careers. In his early years, he was generous and righteous, but in his later years, he changed his mind and took money as big as the sky. It’s not just money that needs to be avoided. There are many other things going on. There is a novel "The Appearance of Officialdom", which describes an official who became addicted to officialdom. When he was about to die, he was lying on the bed at home and had entered a dying state. At this time, he had only one thought in his heart: he was still an official, and he was still in a state of death. To live up to official addiction. So the two adjutants stood at the door of the room and took out their old names. One adjutant read: "So-and-so officer is coming!" The other adjutant read: "I'm sorry, sir, stop him!" He was satisfied with it. I used to think that this novel was too sarcastic; as I got older, I realized that it was not sarcastic at all, and there were indeed many such people. Some people are very lively when they are doing things, but after retirement, they are worried and annoyed at home. In addition, there was a man who was said to have built a famous building and was already very rich. A general asked him, since he is so rich and so old, why are he still working so hard to make money? The old gentleman replied that it was precisely because he was older that he worked hard to make money. If he stopped making money, he would not have many opportunities. What kind of philosophy of life is this? A friend said that a certain old gentleman was also very rich and specialized in saving U.S. dollars. Before going to bed every day, he must open the safe and take out the U.S. dollars and count them before he could sleep. Reading this kind of story, I feel more and more that the cultivation of "precept" is too important. It is not just for fame and fortune. It will be quite comfortable if you can understand these principles in life and understand them. Otherwise, it will be very painful if you have no spiritual arrangement in your later years. Therefore, Confucius' three precepts in life are worthy of vigilance.
