When choosing the topic of the thesis, we should all have done the investigation, and we will find and choose one or two questions to demonstrate, so the theoretical basis of the thesis is the process of proving and explaining the problems. Of course, you need to prepare a lot of materials and useful and real data, and slowly start answering questions. Naturally, I wrote those things that prove the point of the paper, and these things are the theoretical basis of the paper.

However, it should be noted that when proving one's point of view, duplicate checking may draw lessons from many documents, which needs to be clearly marked. Otherwise, it is likely to be marked as plagiarism when checking duplicate. If the repetition rate is too high, we may have to start writing the paper again, which is the result that none of us want to see. I also hope that when you are writing a paper, you should pay attention to the number of citations and reference materials and their marked formats.
