Being influenced by the 1917 Russian October Revolution, ''La Jeunesse'' also began to promote Marxism and its philosophy. From September 1920, ''La Jeunesse'' became a propaganda tool of the Communist Party of China. It was shut down in 1926. In the early days, ''La Jeunesse'' had influenced thousands of Chinese youngsters including many leaders of the Chinese Communist Party.
