What is the relationship between patriarchal clan system and the origin of Confucianism?

The patriarchal clan system in China feudal society was linked by the blood relationship of clans and combined with the state system.

Judging from the "three cardinal guides", the main content of hierarchical relationship involves the field of "the monarch is the minister", while the content of patriarchal clan system mainly revolves around "the father is the son" and "the husband is the wife". This is actually maintaining the feudal ethical relationship centered on patriarchy and husband power. According to the traditional etiquette system, Confucianism believes that "the foundation of the world is in the country, and the foundation of the country is at home", so it is convinced that home and country are interlinked. To promote "home" to the height of governing the country and the world, it is necessary to embody this patriarchal ethical relationship in legislation.
