1. Gone with the world is a master. Mainly freedom of thought, lack of central authority, such as the contention of a hundred schools of thought in the Spring and Autumn Period and the Warring States Period, literati and celebrities in the Wei, Jin, Southern and Northern Dynasties (especially when the imperial power in the Eastern Jin and Southern Dynasties was weak and the gentry was strong), and the Republic of China era.

People who first came into contact with western learning naturally became the first people and made great contributions.
