Sending a paper to blind evaluation will hide the information of the author and tutor. Generally, it will be sent to famous teachers in similar colleges or similar majors for evaluation, and the evaluation teachers will give their opinions, and then the papers will be sent back to the school for evaluation. Usually 3-5 people will be sent to review. Of the five people, if four people agree that the paper is passed and meets the requirements, they can reply, then it is ok. Otherwise, it will be modified again. If the revision fails to meet the specified requirements, the defense or graduation will be postponed.
