The core of "the way of university" is "nourishing qi to level the world", which is also the core strategy of Confucian way of governing the country. After the Qin Dynasty, emperors of all dynasties respected Confucianism, and "University" set up a ladder for politicians, so "University" became a compulsory subject for emperors of all dynasties.
Extended data:
Confucianism emphasizes that "self-cultivation is the premise of governing people". Therefore, self-cultivation is not only the fundamental purpose of "university" thought, but also the starting point of governing the country and leveling the world. We must improve our moral cultivation to achieve family harmony, social harmony and even world harmony.
It can be said that self-cultivation is an important thought of Ceng Zi, who regards self-cultivation as the basis of realizing benevolent and moral governance. Taking a gentleman as the standard of self-cultivation, he put forward a series of ideas on how to speak, do things, treat people and make friends. "Nourishing qi and calming nerves" is not only a compulsory course for emperors.
Confucianism advocates the positive spirit of being born, and encourages everyone to take self-cultivation, family harmony and world peace as their responsibility. The political ideal of Confucianism, that is, to be upright in front of oneself, cultivate one's morality, govern the country and level the world, can be said to be the essence of China's ancient political culture.
