Can I pay social security in two places at the same time?

Workers can pay social security in two places at the same time, but only one of them can be reimbursed. The social insurance law stipulates that employers and workers shall pay jointly according to the provisions of the state. Employees who are not employed by the employer can pay social insurance premiums directly to the social insurance premium collection agency, but can only pay basic medical insurance premiums and basic old-age insurance premiums.
