Why does Xidi absorb the essence of China traditional culture like a sponge?

Xidi was founded in the Northern Song Dynasty and developed in the Ming Dynasty. At that time, Zhu and others put forward Neo-Confucianism, and ethics gradually rose and developed. China's cultural atmosphere is respecting Confucius and attaching importance to education, with three cardinal principles and five permanents. Cultural people also pay more attention to inner exploration and discovery. They feel their desires and thoughts and try to control them.
