I paid two old-age insurances and want to return one. How can I return it?

Legal analysis: two social insurances can be combined. For overlapping parts, some local regulations can be combined, but it cannot exceed 300% of the local payment base, and some local regulations can only choose the one that pays the most.

Legal basis: Article 39 of the Labor Contract Law of People's Republic of China (PRC), if a laborer establishes labor relations with other employers at the same time, which has a serious impact on the completion of the work tasks of the unit, or if the employer refuses to make corrections after being put forward by the employer, the employer may terminate the labor contract.
