Master's thesis needs blind evaluation and external review, in which blind evaluation belongs to spot check, and external review should be sent to designated counterpart colleges for evaluation by professional teachers. Blind evaluation is the duplicate checking rate of machine review, and external review is the quality of papers reviewed by professional tutors. The master's thesis is still sent to the teacher who submitted it once for review.

Generally, the re-examination will be sent to the original teacher, unless some schools will change other teachers to help pass the re-examination. If there is no school operation, the second trial will generally be sent to the teacher who tried the first trial. Generally, blind evaluation means that the content and topic of the paper can't involve your tutor's name and your name, and it is usually sent to foreign schools for evaluation. The reviewer won't know who this paper belongs to and who is the instructor of this paper, so it's called blind review.
