Comparatively literature and general literature are both important fields of literature research, but their goals and research methods are different. The main purpose of comparison literature is to compare the literary phenomena of different cultures, different countries, and different historical periods to explore the differences and similarities between literature, so as to deeply understand the essence of literature and the historical development process. The research methods of the comparison literature mainly include the collection of the comparison literature materials and the analysis of the comparison literature. Overall literature was to study the overall phenomenon and development trend of literature, including the types, theme, style, techniques, etc. of literary works, as well as the reflection and influence of literature on society, politics, economy, etc. The research methods of general literature mainly include the analysis of literary works and general literary evaluation. Therefore, although both of them are important fields of literature research, their purposes and research methods are different.
