Explain the characteristics of Xia, Shang and Zhou political systems with historical facts

The hereditary system of the throne was implemented in Xia and Shang Dynasties, which replaced the abdication system in primitive society. It is said that Yu Xia's prestige rose after the success of flood control, and he became a sage in the eyes of the people, so he inherited Shun Di's rights and became the highest political leader. Before Yu, the transfer of political rights was usually realized by abdication. After Yu's death, Qi, Yu's son, inherited Yu's position, and his political rights evolved from "passing on saints" to "passing on children", thus starting the system of "ruling the world".

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 Dynasty politics is the close combination of theocracy and kingship, and all political affairs of Shang Dynasty were decided by divination. It also dominates national politics through this means. The time of implementing the enfeoffment system in the Western Zhou Dynasty began in the Zhou Wuwang period.
