The saying "My uncle will die by having his hair cut off in the first month" originated from the Qing Dynasty.

Since the Qing army entered the customs, the Qing emperor decided to implement a strange hairstyle in order to "pacify the surrounding areas and stay in the Central Plains." He shaved his hair from the front to the top of his head, then shaved the hair around him, leaving only a long braid in the middle. In order to unify the country, especially the ruling ideology, this hairstyle should be widely promoted in the Han Dynasty. The medium of realization is the barber. The Qing government gathered barbers from all over the country and gave each person a sacred flagpole.

Under the high pressure of the Qing Dynasty and the gradually stable rule of the prosperous age, the policy of shaving hair was implemented normally. Some literati and officials no longer shouted "the head can be cut off but the hair cannot be shaved", but instead "don't shave the head in the first month" to express their longing for the previous dynasty.

This statement is said to come from Volume 2 "Customs" of "Ye County Chronicles" published in the 24th edition of the Republic of China:

"I heard that the elders of Zhuxiang talked about the edict of shaving their hair before Qing Qing It was implemented in the first month of the fourth year of Shunzhi, and the Ming Dynasty's system changed. People thought of the old emperor because of the shaved hair, so it was called "remembering the old" for a long time, so it was mistakenly called "dead uncle".

Extended information:

In fact, the saying that "my uncle died after having a haircut in the first month" actually originated from a "misunderstanding." After the Qing Dynasty, the Han people were forced to shave their hair and leave braids. They missed the previous dynasty and were unwilling to do so. They would refuse to shave their hair during the first month of the year to commemorate it, which meant they missed the old dynasty. "Dead Uncle" is a homonym for "missing the past". After people's misinformation, he became the "dead uncle".

According to research, after the Qing Dynasty entered the customs in 1644, the government required all men to have "shahutou", that is, to shave the hair on the forehead and tie a braid at the back of the head. So many people combined compliance with traditional habits with the emotion of missing the Ming Dynasty, and agreed that no one would shave their heads during the first month of the year, and named this action "sijiu", which means "missing the past history." But with the passage of time, word of mouth and rumors, the homophonic pronunciation of "nostalgia" became "dead uncle", and the folk custom has been passed down to this day.

In a certain sense, the core of Chinese culture is a "culture of human relations", which emphasizes kindness to father, filial piety to sons, and respect to brothers, brothers, and friends. This cultural background has caused the original "misunderstanding" to form a powerful strength. With the development of society, people should make choices in inheriting "festival customs". Modern people should keep pace with the times and understand the cultural connotation of the Spring Festival. The Spring Festival has changed from "emphasis on rituals" to "emphasis on culture". Don't let it be because of a "Misunderstanding" affects people's normal lives. It is understood that in some big cities in southern my country, the rule of not getting a haircut during the first month has gradually faded, but in a wider scope of our country, this old "year custom" still exists, and people need to update their concepts.
