There are many advantages to publishing sci papers, but there is no uniform requirement. Some key universities require graduate students to submit articles in sci journals, while others encourage students to publish sci papers, and have established reward mechanisms. Maybe a paper will be awarded 30,000 to 50,000, or some other awards.
There are also some schools that do not force students to publish sci papers. The specific requirements are as follows: Postgraduates must publish one or three papers during their graduate studies, which is a requirement for students' academic level.
