It's best to quote some, at least ten places, and write some enlightening and helpful references when listing documents, including more than 30 undergraduate, more than 60 master, and more than 0/00 doctoral thesis/kloc. It is best to have some foreign documents. Many teachers will know how to write when they look at the references, so the reference part is very important and needs to be taken seriously. In addition, it is best to refer to master's and doctoral dissertations and core journals. I hope the answer is helpful to you, and I wish you a smooth graduation.
