In fact, the saying that "my uncle died of a haircut in the first month" actually stems from a "misunderstanding". According to research, 1644, after the Qing Dynasty entered the customs, the government required all men to keep a "casserole head", that is, shave their hair on their foreheads and tie a braid behind their heads.

Therefore, many people, in combination with observing traditional habits and remembering the feelings of the Ming Dynasty, stipulate that everyone should not shave their heads in the first month, and name this action "thinking about the past", which means "remembering the past history". But over time, word of mouth, the homonym of "thinking of the old" became "dead uncle", so there was a folk custom that has been passed down to this day.

Han men have been storing hair since ancient times, "wearing leather clothes and influenced by their parents", and dare not hurt or move. Shaving your head is like killing someone. The punishment of "delivering" is not within the five punishments, but it is also a punishment. Cao Cao of the Three Kingdoms cut his hair and changed his head as proof. This habit has been abolished since the Sui and Tang Dynasties: immature children wear their hair around their necks and shawls; When I am an adult, my hair is always tied in a bun.

At that time, in order to unify the national costumes, the Qing Dynasty forced Han people to imitate Manchu, shave their heads and wear braids. Manchu used to be a hunting tribe. For practical convenience, they drew a straight line from both ends of the frontal angle, and all the hair outside the straight line was shaved off, leaving only the hair on the top of the head braided. Customs have a strong inheritance and will change with time and place. After the Manchus entered the Central Plains, they forced the Han people to shave their hair. "Leave your hair, leave your hair."

The Han people fought to the death in World War I, and many people died. In the end, they were forced to shave their heads, leaving "suncus murinus's tail". In this way, if you don't shave your head in the first month to "miss the old", you will lose the cultural and psychological foundation on which you live, and you will be misinformed as "dead uncle" by homophones. In order to resist the rule of the Qing nobles, the Han people invented the saying of shaving their heads in the first month. If you don't shave your head for a month in the first month, you don't shave your head for a year, in order to remember your ancestors and traditions. In the tradition of China people, uncle is a symbol of justice. It is usually my uncle who presides over the justice of family separation.
