Hello, dear ~ I'm glad to answer your question! Doctoral students in school have medical insurance, while doctoral students in school have medical insurance, but there is no old-age insurance. After graduation, whether you are officially employed or engaged in postdoctoral research in postdoctoral mobile stations, you have medical insurance and five insurances and one gold. The state pays you social insurance. 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. Even some people have just been admitted to a doctor's degree and have already worked in an outside company. In this case. As long as you work outside and sign a labor contract, you can pay social security. Full-time doctoral students have medical insurance. The situation of full-time doctoral students is more complicated, some are on-the-job doctoral students, some are leaving the original unit personnel relations and transferring to colleges and universities. On-the-job employees are treated according to the original employees' medical insurance, and full-time employees are treated according to the students' medical insurance. They pay a small amount of fees every year and enjoy appropriate medical insurance benefits.
