In order to consolidate its position, the ruling class developed religious etiquette into a ritual system. The etiquette in this period was mandatory and hierarchical, and the ceremony was branded with class.

For example, Zhou Li, Yi Li and Li Ji in the Zhou Dynasty are the earliest etiquette monographs in China. In the history of more than 2000 years after the Han Dynasty, they have been the classic works of the state in formulating etiquette system, and they are called the Book of Rites.
