What are the three systems of the Western Zhou Dynasty and their internal relations? Xia, Shang and Zhou politics.

The hereditary system of the throne was implemented in Xia and Shang Dynasties, which replaced the abdication system in primitive society. Political rights evolved from "passing on sages" to "passing on descendants", and the system of "ruling the world" began.

The nobles of Shang Dynasty took blood as the link and practiced patriarchal clan system. All clans are political entities.

Another major feature of Shang politics is the close combination of theocracy and kingship. All political affairs in Shang Dynasty were decided by divination, and national affairs were also dominated by this means.
