As early as the primitive clan period, the patriarchal clan system had sprouted, but the formation and appearance of a complete system to maintain aristocratic relations was a matter of the Zhou Dynasty.

Under the patriarchal clan system, "the emperor founded the country, the vassal established the family, the Qing set up a side room, there were two doctors, and the scholar had the son of an official" (Zuo Zhuan was published for two years), forming a systematic and complete system.
