What is the significance of patriarchal clan system to China culture?

The patriarchal clan system evolved directly from the patriarchal clan system in primitive society. It establishes and consolidates the position of paternal parents in the clan by stipulating the clan hierarchy, thus ensuring the stability of kingship. The core content of patriarchal clan system is the eldest son inheritance system. That is, the eldest son inherits his father's suzerain status and the illegitimate child is enfeoffed. The emperor's legal heirs, princes and doctors are first and foremost the eldest son. Even if the illegitimate child is older than the eldest son, he cannot be an heir, that is, "it is not virtuous to establish a monarch, and the son is not long." Patriarchal clan system, that is, clan regulations, is a kind of power inheritance system, which determines the succession of the throne in the form of eldest son inheritance system, perfects and consolidates the enfeoffment system, and prevents disputes between nobles because of power inheritance. Under the patriarchal clan system, the concept of hierarchy is very strict, hierarchical and orderly. It takes the blood relationship as the link and the relationship between monarch and minister as the discipline, which ensures the monopoly and privileged position of the nobility in politics and maintains the stability and unity within the aristocratic ruling group. Hereditary system, patriarchal clan system and enfeoffment system together constitute the main body of Xia, Shang and Zhou political system, which has a far-reaching impact on China society.
