Sima Qian recorded that "Xia" is the name of a tribe headed by "Xia Hou" and composed of twelve clans: Youhu, Younan, Zhuan, Tongcheng, Bao, Fei, Qi, Gui, Xin, Ming and Zhuan. After the establishment of the Xia Dynasty, the tribe was named Guo. Xia Dynasty was built on the ruins of primitive social system.

Xia Dynasty was built on the ruins of primitive social system. In the process of the gradual disintegration of the primitive tribal system, the patriarchal clan system has become a destructive force, because the hereditary kingship and hereditary nobility of the hereditary country have gradually developed on the basis of the patriarchal clan system.
