The crux of the problem lies in the fact that the general review is conducted by the teachers in our own school. Because it is our own school and the tutors are familiar with it, it may be easier. Blind evaluation is sent to other schools and evaluated by teachers from other schools (maybe teachers from several different schools form evaluation teams), which will definitely be stricter. Some schools may have a good relationship with the submitting schools, and the passing rate will be higher. If you write well, you don't have to worry about these problems. Even if the relationship is not good, the teacher will not be embarrassed to write well. Bad writing depends on luck. In order to ensure the fairness and objectivity of the examination, the blind examination of the master's thesis is to examine all the contents of the thesis, not excerpts, but to hide the identity information about the author, including school information, just to ensure fairness. It should be noted that there seems to be no blind trial now, but all defense papers must be blind, and the blind trial adopts a one-vote veto system. As long as one vote fails, the paper will fail.
