What is a theory of governing the country advocated by Confucianism?

Because Emperor Wu of the Han Dynasty advocated Confucianism, he mainly adopted the Confucian idea of "filial piety", and both Han Dynasties advocated "filial piety governing the world". This theory of governing the country later developed into the theory of "loyal ministers seeking filial sons", which looked at governing the country from the perspective of moral character and being a man.

"University" said that "everyone knows everything, people are sincere, honest and upright, upright and self-cultivation, self-cultivation and self-cultivation, self-cultivation and self-cultivation, self-cultivation and governing the country, and governing the country and leveling the world." The meaning of man lies in doing his duty. This is the central idea of Confucianism and later Neo-Confucianism.
