What does it mean to read the tutor's thesis after the postgraduate entrance examination? How many newspapers do you read? Which tutor's thesis should I look at specifically? So many mentors?
First of all, you have to consider the direction you want to learn. Then there are some mentors for you to choose your direction. Choose one you like, remember to contact him and see how the other person's attitude is. After all, some tutors don't want you to say something perfunctory. Contact a tutor who feels more confident. Then I have to read some papers of this teacher to understand his research topic. Of course, if we have enough time and energy, we can look at the papers of other tutors in this direction. After all, the more the better.
