What should I do if I resign and study social security?

After the party resigns for graduate school, social security can be purchased by itself; If there is no work unit, it cannot be paid by the work unit. China's "Social Insurance Law" stipulates that the employer shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay.
