Does it make sense to "spoil a dutiful son and extend a dutiful son"?

This is meaningless. This sentence is too absolute, ignoring the philosophy contained in it. In fact, the real meaning is only to educate children not to spoil them, not to say that they must beat them. Some people are very rebellious, and the more they fight, the more disobedient they become.

According to my recent understanding of Ma Yuan, contradiction is unity of opposites. Sticks may give birth to filial sons or rebellious sons. The key is to use great art, not too absolute. If you just follow this sentence blindly and ignore what you really want to express, it may cause indelible harm to your child, and what's more, it may cause irreparable mistakes. So everything has two sides, and we can't look at it from one side alone.

Moreover, China's parents always seem to like to talk about this sentence. I don't think parents should overemphasize this sentence, because China people's argumentation thinking is the stronghold of quoting classics, not the logical romance in the West. This is very dangerous. If you are not careful, you will fall into sophistry. However, children are actually eager to get encouragement and praise from people they care about. Blindly criticizing and scolding will make him lose, and then disappointed, and thus more rebellious, and there will be no so-called dutiful son. Only children who know their mistakes and don't change them, but get worse, can play their role properly.

In addition, stick and stick education is no longer applicable to today's era. Bonzi's education is not a filial son, just like those who have been forced to turn over for a long time. Rebellion, depression and inferiority are all negative emotions. This kind of education is based on the backwardness of the times, low knowledge reserve (illiteracy) and humanistic atmosphere. Now emphasize equality. You and your children are on an equal footing, which can reduce the gap between them. You can guide your child in a reasonable way, and you don't have to fight. Children's physical and mental health is closely related to their parents. Children's behavior is subtly influenced by early adult behavior, so I hope everyone must educate children correctly.
