Does it matter if social security is paid in different cities?

Legal Analysis: Is it OK for a person to live in different cities? Pay two social insurances at the same time, but you can only enjoy one treatment in the end. Social security paid in overlapping time can be returned in cash when social security is merged. Only one social security can be refunded, the part paid by the individual can be refunded, and the part paid by the unit cannot be refunded. The remaining non-overlapping ones can be moved out of the merger.

Legal basis: Article 12 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employer shall pay the basic old-age insurance premium according to the proportion stipulated by the state and the total wages of its employees, which shall be credited to the basic old-age insurance pooling fund. Employees shall pay the basic old-age insurance premium in accordance with the proportion of wages stipulated by the state and record it in their personal accounts. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employing unit and other flexible employees who have participated in the basic old-age insurance shall pay the basic old-age insurance premiums in accordance with state regulations and record them in the basic old-age insurance pooling fund and individual accounts respectively.
