In ancient China, which was more important, father and son, monarch and minister, and seniority?

For example, the emperor's empresses and concubines, when meeting their parents, can't be experts, and must accept their parents' courtesy.

The "Three Cardinal Principles" means that "the monarch is the minister's guide, the father is the son's guide, and the husband is the wife's guide", which requires that the minister, son and wife must absolutely obey the monarch, father and husband, and also requires the monarch, father and husband to set an example for the minister, son and wife. It reflects a special moral relationship between monarch and minister, father and son and husband and wife in feudal society.
