On-the-job graduate students (those who study while working generally need a bachelor's degree certificate, and those who don't have a degree certificate can only account for 10% of the admission rate, which is simple to enroll and difficult to graduate, and only have a degree certificate, which is different from the unified master's degree).
Graduate students in the unified examination (most schools do not need a degree certificate, but they must have a diploma. After admission, you can study full-time, complete the degree course and pass the defense, and you can get a diploma and a degree certificate)
