After teaching in colleges and universities, I review my own graduate thesis and that of other schools every year. It is estimated that in the past six or seven years, I have reviewed about one or two hundred graduate papers, and on average, about 20 to 30 papers pass each year.

In order to simplify this problem, I divided the review papers into two categories. One is our school's papers, which are nominally blind reading, but in fact we can always find each other's information. The other kind is foreign school papers, which are really blind trials. Because I don't know each other, it's natural to fight decisively and mercilessly.
