Mao Zedongs Talks at the Yanan Forum on Literature and Art has an enriched and clear literary meaning generation. From the perspective of utilitarianism that literature shall serve for the political purposes, it emphasizes that the politics is the first standard, so as to use the social effects to reverse the norms, adjust the literary creation, and provide a maneuverable exterior route for the meaning production of revolutionary literature and art. Both the new interpretation of the human nature and the class character, and the dialectical explanation for extolling the good and exposing the problems have set up a most fundamental value dimension and value presentation mechanism for the meaning production of revolutionary literature and art.
