1978, which was in the period of bringing order out of chaos. Due to the need of research work, Mr. Deng wrote a series of articles, reviewing and reflecting on the historical experience of literary heritage research since the May 4th Movement and the founding of New China, including the review and discussion on the inheritance of literary heritage since the May 4th Movement, some problems of literary heritage inheritance since the founding of New China, the May 4th literary revolution and literary tradition, and adhering to the guidance of Marxism-Leninism theory. Improving the research level of ancient literature and other papers have made a practical discussion on the historical experience of inheriting literary heritage since the May 4th Movement, especially since the founding of New China, and put forward many opinions, which played a very good role in bringing order out of chaos in the research field of literary history at that time. But he also has a clear understanding of these papers. He once told graduate students that he knew that Comrade Hu Qiaomu was full of praise for the papers on the inheritance of literary heritage since the founding of New China, and he also heard the praises from senior experts such as Cheng and Wu Diaogong, but he himself thought that those articles had weaknesses in theory. From the late 1980s to the mid-1990s, during his tenure as the president of China Modern Literature Society, Mr. Deng put forward his own views on some major issues in the discipline construction of modern literature, such as "Tradition, Innovation and Academic Democracy —— Speech at the Opening Ceremony of the Fourth National Symposium on Modern Literature", "On the Establishment of Modern Drama Literature Discipline" and "Patriotism in Modern Literature Always Inspires Us", which were produced in the field of modern literature research. Those series of articles, as well as later articles such as A New Theory of Chinese Studies and Chen Duxiu's Extreme, Cultural Debate and Scholars' Evaluation, mainly put forward the following viewpoints: As historical reality shows, since the May 4th New Culture Movement, in the whole revolutionary literature movement, Marxism entered the field of ancient literature research relatively late, and experienced cognitive mistakes in the early stage until 1938. With the publication of Comrade Mao Zedong's Position of the Chinese Productive Party in the National War, Theory of New Democracy and Speech at Yan 'an Forum on Literature and Art, the revolutionary literary and art circles have reached a comprehensive and mature level of understanding of Marxism in inheriting literary heritage. However, since the founding of 1949 New China, due to various reasons (mainly the political influence of "Left"), there has been a wrong deviation from the correct theory and understanding in practice. In view of this historical experience, Mr. Deng believes that the study of China's ancient literature should not only adhere to the guidance of the overall view of Marxism, but also pay attention to learning and absorbing various specific and effective research methods and critical paradigms in the West. This kind of research is not only the interpretation and explanation of the macro or micro literary history phenomenon, but also the sublimation and summary of the theory, thus enriching the existing literary concepts and theories and making contributions to the development of human culture.

Those articles on the subject construction of modern drama literature represent Mr. Deng's views on the subject construction of ancient literature (including modern literature): there are two main signs to measure the prosperity and development of a subject: first, many research works have been produced in the historical development of this subject, among which what people usually call authoritative works have appeared; Second, in the historical development of a discipline, as a synchronous phenomenon of many research works, a group of researchers appeared, among which there should be academic masters. The prosperity and development of a discipline is formed in the process of historical accumulation, and people always use historical accumulation in the pursuit of innovation. Only when innovation and accumulation reach dialectical unity can the discipline of ancient literature develop continuously. Based on this academic viewpoint, Mr. Deng has always offered the course "History, Present Situation and Methods of China Ancient Literature Research" for doctoral students. When he was invited to give lectures in universities all over the country, he always chose "ancient literature research and methodology" as his key topic.
