Can you make up for a low social security base?

The contribution base of social security is determined according to the average salary of employees in the previous year, and after making contributions in accordance with the regulations, you can not make retroactive contributions. Generally speaking, retroactive payment of social insurance premiums is allowed only if the following three conditions are met: there is a labor relationship with the insured unit; the legal retirement age has not been reached; and there are unpaid fees that should be paid.
