However, any academic or graduation thesis always carries out its own research on the basis of others' research, and it is impossible to make a thesis entirely on its own imagination. If you don't seriously study the current situation of your thesis research problems and don't understand the main academic viewpoints and research results, your thesis itself is very empty or not research results. Since it is a paper made on the basis of other people's research, there will naturally be many books and papers you know about other people's research results as a reference.
