1. Persons who have graduated from or obtained a master's degree.

For the management of doctoral students in China, the loose management mode of tutor taking students is adopted. Basically, students attend classes for one year and do papers with their tutors for two years. Because there are not many projects, most doctoral students devote themselves to job hunting after one year of class and practice in various companies to prepare for future work.
