The blind examiners are all undertaken by peer experts outside the school, and graduate department is responsible for selecting from the expert database.

The external evaluation of papers is also called blind evaluation, which is to send dissertations without the author's name to unknown experts, so the evaluation should be the most objective.

General colleges and universities, especially graduate schools, have relevant regulations on blind examination of papers on a regular basis, and most of them randomly select a certain number of papers for blind examination. The graduation thesis should reflect that the author can accurately grasp the basic professional knowledge he has learned.
