The new democratic revolution refers to the bourgeois democratic revolution led by the proletariat in colonial and semi-colonial countries in the era of imperialism and proletarian revolution. The so-called "new" is the old democratic revolution, which was led by the bourgeoisie in Europe and the United States in the 17th and 18th centuries, aimed at overthrowing the oppression of feudal despotism and establishing the political rule of the bourgeoisie. The May 4th Movement, which broke out in 1949, was a turning point for China to move from the old democratic revolution to the new democratic revolution. The establishment of the the People's Republic of China in 1949 marked the basic victory of China's new democratic revolution. And this work is to celebrate the 100 anniversary of the victory of the new democratic revolution.
