To write a thesis, we should first sort out the main viewpoints in the collected and read monographs and papers, and select the most representative authors from them. When writing your graduation thesis, summarize these main points, and indicate the year when you represent the author and express your opinions. It is also necessary to comment on the shortcomings of domestic and foreign research, that is, what aspects are not involved, whether there is a research gap, or the research is not in-depth, what theoretical problems have not been solved, or what shortcomings exist in research methods, which need further study.
