This easy-to-understand and well-defined Improvement of Literature provides a new "standard" for the writing of later papers (from the new culture to the present), which is conducive to its standardization. First of all, the level is clear and the arguments are sufficient. The article first summarizes the "eight things", and then discusses the "eight things" in detail by using a large number of arguments at home and abroad. For example, in the article "Don't use the canon", every time he discusses a meaning, he will cite concrete examples, which can be said to be a deep effort, which fully embodies the rigorous attitude of being a scholar in academic research. It is this attitude that leads to the conclusion that "my humble opinion is still unclear, and Comrade China is right to correct it frame by frame." This attitude was criticized by people at that time and later as vagrancy and cowardice. In his reply to Hu Shizhi, Chen Duxiu was also extremely dissatisfied with Hu Shi's attitude of "tolerating dissidents and discussing freely", arguing that "when vernacular Chinese is regarded as authentic literature, its right and wrong are very clear and can not be discussed by opponents". It was Chen Duxiu's resolute attitude that made the literary revolution develop rapidly. In the early days of the literary revolution, this "one size fits all" resolute attitude is necessary, because it is a new thing in itself. However, when we review the history of the Cultural Revolution, we find very similar problems. The Cultural Revolution took an extremely decisive and tough attitude towards the so-called "petty-bourgeois ideology", which was absolutely unacceptable, but the result was completely contrary to the New Culture Movement. The literary revolution advocated by Hu Shi and Chen Duxiu laid the foundation for the prosperity of literature and trained many talents. However, the literary revolution of the Cultural Revolution almost caused the "desolation" of literature and lost a large number of talents. I think Hu Shi's attitude should be more cautious, and literary problems should be solved through discussion. Secondly, the method of evolution. Influenced by Yan Fu's theory of evolution in the early years in Chengzhong School, this paper studies China's new literature from the perspective of evolution, which provides a new method and opens a new horizon for the study of China literature after Wang Guowei.
