The number of papers that need to be published in sci varies with the institutions where doctors study. Generally speaking, most institutions require doctors to publish 1-3 sci papers, as long as there are enough papers, they can graduate. But not all PhDs graduate after three sci papers. Other units directly require doctors to send more than 5 sci papers before graduation. Therefore, doctors who have issued 1-3 sci papers are required to graduate. Compared with doctors who have published at least 5 papers, they are happy and have a higher chance of graduation.

It's getting harder and harder to graduate from China. The main reason is that doctoral students are required to publish sci, even exceeding 1 article. For Gamboshi himself, it is not easy to publish an sci, and it is even more difficult to publish many articles. Not to mention adding conditions on the basis of sci, such as how many articles to be published in the first district, how many articles to be published in the second district, and even the number of influencing factors selected for sci publications. These conditions further increase the difficulty of issuing sci. Simply put, if Bo Shi wants to graduate, he must be able to send sci. If you have difficulty in sending sci yourself, seek professional guidance. The sooner you start writing, the more likely you are to graduate.
