China Shiyou University is very strict in blind examination of graduate thesis. According to the relevant information, the graduate thesis submitted by China Petroleum University has to go through three strict checks. The first one is strictly checked by the tutor, the second one is strictly checked by the Education Commission, and the third one is strictly checked by the graduate school. China Shiyou University will put an end to counterfeiting, and will deal with it seriously if it is found to be forged, altered or pieced together. So the review is very strict.
