Abstract
Chen Du-xiu, a leading thinker and revolutionist in modern China, is the person who showed an ideological upheaval from liberalism to socialism. He called for personal freedom and the values of the individual, but when he came upon a national crisis and the Russian Revolution succeeded, he converted to socialism. In the process, he combined democracy with ethnicity to lay the foundation for Chinese social democracy. As one of representative thinkers of modern China, he changed his position for Chinese people and Chinese society, and it soon formed the basis of modern Chinese socialism, emphasizing the right to the survival of the people and people's democracy.
