According to recent research, young men and women in clan society must participate in the "Cheng Ding Ceremony" after reaching maturity in order to become full members of the clan commune and enjoy their due rights and fulfill their due obligations. The crowning ceremony (crowning ceremony) of the Zhou Dynasty was changed by this "Chengding ceremony".
When a zhou dynasty aristocratic man was twenty years old, his father presided over the crown ceremony in the Zongmiao Temple. Before the ceremony, the day of shì (the date of the crowning is selected) and the guest (the guest who is crowned is selected). During the ceremony, the guests are crowned three times: first, the cloth crown (zī) is added, indicating that there is a privilege to govern from now on; the second is biàn, which indicates that they will serve in the military from now on; and finally the knighthood is added, indicating that they have the right to participate in the sacrifice from now on. (The crown is made of black linen, the leather is made of white deerskin, and the knighthood is a red-black flat-topped hat, which is worn during sacrifice.) After the guests toasted, they went to see their mother, and the guests took the "word", then went to see their brothers and sisters, and finally wore a top hat and a dress with gifts to see Dr. Guojunqing and Mr. Xiang. After the host toasts the guests and gives gifts, the ceremony is completed.
Noble men can marry their wives after they are twenty years old, and noble women marry at the age of fifteen. The so-called hair tie is to curl the hair in a bun on the top of the head (different from the childhood hairstyle), indicating that the year is "adult" and can get married. Su Wushi, volume 29 of the Anthology of Literature, says: "As husband and wife, there is no doubt about love and affection." "It can be seen that this custom has been passed down for a long time.
