As a modern literary figure,Guo Mo-ruo published a series of articles explaining Chinese literary before and after the national form debate from 1939 to 1942.Scrolling through its many concepts in a special histor-ical context,it reflects its aesthetic adherence to the May Fourth literary tradition,and has an intellectual complex that inherits the new literary tradition of the May Fourth movement;At the same time,he advocates using the dis-cussion of"ethnic forms"to absorb the strengths of folk and foreign forms,breaking through the tense relationship between"Europeanization"and"nationalization",and achieving the nationalization and popularization of literature and art through the reform of literary forms.This concept is very different from the absolute theory of"folk forms"and stands out in the complex debate on"ethnic forms".In short,Guo Mo-ruo's literary and artistic ideas have objectivity and foresight,which not only pointed out the direction for anti Japanese literature,but also provided a broad perspective for the development of modern Chinese literature.
