Who can help find the official list of Xia, Shang and Zhou? ask sb. to do sth.

The Xia dynasty lacked exact written records, and the official list no longer existed.

In Shang Dynasty, there were officials such as Xiang (in charge of politics), Qing Dynasty (in charge of military affairs) and Bu (in charge of sacrifice and divination) in the central government, and officials such as Hou and Bo in the local government.

Zhou's political system is characterized by the combination of enfeoffment system and patriarchal clan system, that is, the system of "emperor-vassal-QingDafu-scholar".
