Abstract: “Writing carrying doctrine”,“poems expressing wills” and “poems endowed with feeling” were key concepts in Chinese classical literary criticism.“Writing carrying doctrine” emphasized unconditional subsidiary to doctrine,“poems expressing wills” emphasized the expression of subjective feelings,while “poems endowed with feeling” was an inclusive concept.The writers during the May 4th movement chose the concept of “poems expressing wills” historically under the dual consideration of social enlightenment and establishment of modern literature.They carried on a two-way criticism on the concept of “Writing carrying doctrine” and “poems endowed with feeling”,while paradoxically hovering in between them.The writers began differentiation in two directions after the May 4th movement,one was the personalized color of “will” faded to “doctrine”;one was the social responsibility of “will” subsided gradually to “feeling”.The differentiation was inevitable when the concept of modern literature gradually diversified and the discipline of modern literature developed.

Key words: &ldquo, Writing carrying doctrine&rdquo, &ldquo, poems expressing wills&rdquo, &ldquo, poems endowed with feeling&rdquo, the concept of modern literature
