I paid medical insurance in Licheng District, Quanzhou City. Can I pay it back in Luojiang District now?

You can pay medical insurance across regions.

If you choose to pay the medical insurance payment period in one lump sum, the payment rate shall be based on 60% of the local social wage at the time of payment, and the sum of the payment ratio of the employer and the employee shall be supplemented to the specified payment period in one lump sum.
