Why can ancient men have long hair but modern men can't be laughed at?

There are two main reasons for this. First, it is filial piety. The body is a skin injury, and parents dare not hurt it. Filial piety begins. It is unfilial to damage the body without authorization; Secondly, in ancient criminal law, shaving hair was called kun 1, which was one of the five punishments in ancient China. Shaving off all or part of hair is a humiliating punishment, which was mainly popular in China from Xia, Shang and Zhou Dynasties to the Eastern Han Dynasty.

Therefore, ancient people's long hair is actually more of an internal factor, not that short hair is not good-looking or long hair is good-looking. I guess if it weren't for the Qing dynasty, our long hair tradition would have left a lot. Although the way of life and work in modern society makes long hair sometimes inconvenient, there are still a large number of people who will follow the tradition of long hair, and those men who have long hair will not be considered as pseudo-art, sissy and so on ~
