"Democracy" refers to democratic thought and politics, and "science" refers to the laws and spirit of modern natural science. The bourgeoisie preached democracy and opposed feudal autocracy, pointing the finger at Confucianism, the theoretical pillar of feudal autocracy; Advocate science and oppose feudal superstition and ignorance. This slogan reflects the requirements of China's political and economic development and the urgent needs of the people, which has effectively promoted the development of the New Culture Movement. However, this slogan still belongs to the nature of bourgeois old democracy and has the limitations of its class and times.

Can't save the country

In the later period of the New Culture Movement, Li Dazhao introduced Marxism into China. The May 4th Movement promoted the spread of Marxism, and finally gave birth to the China * * * Producer Party, which led China's new-democratic revolution to victory.
