Literary theory is far from the other three. I am a student majoring in Chinese language and literature. I have studied literary theory, which is really theoretical, but just look at the catalogue first, circle the topics that can be related to the topic, and then have a general understanding of the theory and determine the topic. Then you can expect to look at the papers related to theoretical knowledge in this designated area and see how people's structure and theoretical knowledge are used in the papers. After this kind of thing, knowledge can be integrated, and then the content inside can easily precipitate.

Or if you have a foreign literature direction, I think you can consider the comparison between Miyazaki Hayao animation and western fairy tales or fables.
