How to deal with it? First, if it's me, if I'm not engaged in the relevant scientific research industry, just a college graduation thesis, and the other party admits plagiarism, then I'll use RMB as compensation. But I think you should still be engaged in related scientific research, or in graduate school. Second, send the relevant evidence of your graduation thesis to the publishing house where the relevant publications of this thesis are published, call the publishing house and think about what you can do now. If you don't work or study, you shouldn't be able to go all the way to find someone who copied your paper, sort out the clues yourself and try to contact the publishing house.
