Why did Chen Duxiu put forward the slogan of fame and learning?

Democracy and science are the core slogans of the New Culture Movement.

The background of the new culture movement is

1, the Revolution of 1911 overthrew the feudal monarchy, and democracy became the general trend.

2. The Revolution of 1911 did not completely change the nature of China's semi-colonial and semi-feudal society. The three mountains of feudalism, imperialism and bureaucratic capitalism still weigh on the people of China. To overthrow these three mountains and realize independence completely, democracy becomes an urgent requirement.

3. The direct reason is that the Beiyang warlord government, which usurped the fruits of the Revolution of 1911, set off a countercurrent of "respecting Confucius and restoring the ancients", and it became the voice of the times to remove feudal ignorance and realize democratic science.
