From 1644, when the Qing army entered the customs, the Qing emperor decided to implement a strange hairstyle that was unprecedented at that time, that is, the standard hairstyle of the Qing people in film and television dramas: shave the hair from the front to the top of the head, and then shave all the hairlines around it, leaving only a middle section and a long big braid.

In order to unify the country, especially the ruling ideology, this hairstyle should be widely promoted among Han people. The medium of implementation is hairdressers, and the Qing government gathered all the barbers in the country and gave everyone a "flagpole" with an imperial edict on it. Subsequently, these barbers walked the streets and took people's hair off one by one with goodwill and goodwill. However, this law was not implemented cleanly at the beginning. After all, there is a saying in the Book of Filial Piety: "If the body is damaged, parents dare not damage it, and filial piety begins." Han people don't shave their heads when they are adults, and both men and women will tie their hair in a bun. Therefore, the haircut order was strongly resisted by the Han people. At that time, the slogan of the Qing dynasty was "keep your hair, keep your hair."

A series of rebellions by the Han people completely angered the rulers of the Manchu dynasty, and the angry Manchu regime began to enforce the order of shaving their heads by means of slaughter-the emperor shunzhi picked a quarrel at random, and at the command, tragedies such as "Yangzhou 10th" and "Jiading 3rd Massacre" appeared one after another, and the symbols on the heads of the Han people, together with their blood, were immediately hoisted to the west by cranes.

As a result, many Han people shouted "Better be a ghost than a shave" earlier. But after all, the neck is not as hard as a steel knife. Finally, most Han people were forced to shave their hair for the sake of their necks. But the resistance didn't stop. Not shaving for the first month was a kind of resistance. Some literati no longer shouted "no shaving", but expressed their thoughts with "no shaving in the first month", which was really "nostalgia" and was misrepresented as "dead uncle" to hide people's eyes and ears.
