Red Classics, a post-Cultural Revolution vocabulary, contains memories of the Cultural Revolution connected with reality. Originally (1980), it was used to refer to the model operas that appeared during the Cultural Revolution. Later (after 1990' s), people driven by nostalgia generally refer to the typical works created under the guidance of Mao Zedong's Speech at the Yan 'an Forum on Literature and Art (1942), which reflect the social and political movement under the leadership of the Communist Party of China and the life of ordinary workers, peasants and soldiers. The works in different periods are titled with the same title, which shows that they have some internal identity in basic ideas, value orientation (social ideal, moral inheritance), creative paradigm, aesthetic style and so on.
