Why did Han men and Japanese men tie their hair before the Qing Dynasty in ancient China?

"Bundle hair" is a word often seen in ancient etiquette, which generally means that men need to tie up all their hair when they reach a certain age, but many people still cling to the image of half-staying and half-tying in film and television images. Indeed, this hairstyle is beautiful. It is always more upright and solemn, and no half is more popular. But in fact, it was normal for ancient Han people to tie their hair.

After the "shaving" in the early Qing Dynasty, the Han people who would rather die than abandon the traditional hair storage have long since disappeared. However, at the end of the Qing Dynasty, after the invasion of foreign powers, the flag braid of the Manchu Dynasty was also cut off, and the image of China people gradually became short hair today. However, before that, Han people would not easily lose their hair because of the influence of their parents.

Before the Qing Dynasty, Han boys did not tie their hair until they were eight or nine years old, and their hair naturally drooped, which was called "drooping hair"; From the age of eight or nine to fifteen, two knots are tied on each side of the head, which is called the "total angle"; At the age of fifteen, the total angle dissolved and tied into a bundle, but there was no crown; At the age of twenty, the coronation ceremony began. Generally speaking, adult hair needs to be tied up, which is the hair of ancient men.
