Master students generally have no requirements for publishing papers after graduation, and it is relatively smooth to go out for cooperation. Doctoral students will be in trouble if they go out. Many schools not only require doctoral students to be the first author, but also require their schools to be the first unit when publishing papers. Some teams even require doctoral supervisors to be communication authors. In addition, when evaluating the achievements of scientific researchers, many units often only admit articles that "the first author and the first signatory are their own units" or (and) "the first signatory of the communication author is their own units".
