Why did ancient people grow their hair?

There are two main reasons for this. The first is that the Filial Piety Classic says that the hair and skin of the body are received by parents and do not dare to damage them, which is the beginning of filial piety. If you damage the body without authorization, it is unfilial; secondly, in ancient times, the punishment for shaving one's hair was called Kun (kun 1 sound) punishment. It is one of the five punishments in ancient China. It is a punishment for shaving all or part of a person's hair. This kind of humiliating punishment was mainly popular in ancient China from Xia, Shang, Zhou and Eastern Han Dynasty.

Kun punishment refers to shaving the prisoner’s hair and beard. Kun punishment is a punishment imposed on the criminal in the form of personal humiliation. The ancients believed that the body, hair and skin were inherited by the parents and they did not dare to destroy them. This was the beginning of filial piety. Also! So being shaved would be a humiliation for him. During the Wei, Jin, Southern and Northern Dynasties, Buddhism was popular; because Buddhists shaved their heads and did not get married, which was a great act of unfilial piety, people at that time called them "Kun people" contemptuously.

Kun punishment originated from the Zhou Dynasty. Those in the royal family who committed palace punishment had their long hair cut off and replaced by palace punishment. By the Qin Dynasty, this nature had been lost and it became a punishment of shaving off the beard and hair of the victim. Growing hair and beards was a normal state for men in ancient China. This type of punishment involves forcibly shaving off the criminal's hair and beard, leaving the criminal in an obviously abnormal state and making him feel pain.

There is a famous story that may be familiar to friends. Once when he was marching, Cao Cao issued an order not to trample on farmland. He wanted to protect the farmers. If someone’s horse trampled on the wheat field, he would be killed. It was a crime of beheading, so Cao Cao's cavalry all dismounted and walked, holding the horse with one hand, using a weapon with the other hand to protect the wheat with a gun or something, and walked carefully. Cao Cao himself did not dismount his horse (one theory is that a pheasant flew out of the ground), but the horse was frightened and jumped into the wheat field. Cao Cao's horse trampled the wheat field. Cao Cao immediately dismounted and called the military judge to ask, what crime should be committed? The military judge said, behead. Cao Cao said, "I'll ask you to execute me." Alas, how is that possible? Anyway, there was this tradition in ancient times. If the punishment is not good enough for the officials, the courtesy is not good enough for the common people, and the law is not imposed on the venerable, how can the commander-in-chief behead him? Cao Cao said that there was no way, so just cut off a piece of hair. He pulled out his sword, cut off a piece of hair and threw it on the ground to show that he had been punished.

So, there are actually more internal factors why people in ancient times had long hair. It does not mean that short hair is not good-looking, or that long hair is good-looking. I guess if the Manchus of the Qing Dynasty had not entered the country, then our long hair would have been There will definitely be a lot of hair tradition left over. Although the way of life and work in modern society makes long hair sometimes very inconvenient, there will definitely be a large number of people who will follow the tradition and keep their long hair, and those men who have long hair will definitely not. It is considered to be fake art, effeminate, etc.

I hope it will be adopted, thank you
