What kind of cultural etiquette was the rite of passage in ancient China?

The most important feature of China's rite of passage in the pre-Qin period is the change of costumes, among which the crown and ornaments on the head are the most special, so the rite of passage is called "crown ceremony" for men and "gift ceremony" for women. In the pre-Qin period, the age of adult ceremony for men was set at 20 years old, while for women, it was decided by whether to allow marriage. Those who are allowed to get married get gifts at the age of 15, otherwise they will get gifts at the age of 20. The way to hold it is to hold it personally, and the location is chosen in the holy place of the ancestral temple. The date needs to be determined by divination. On the day of the ceremony, the host must invite relatives and friends to watch the ceremony.
