I paid my pension insurance in the provincial social security, if I switch to the municipal social security payment, the deemed contribution still counts!

Counts! The number of years of deemed contributions refers to the number of consecutive years of work calculated in accordance with national regulations before the actual number of years of contributions made by the insured employee. According to the provisions of the State Council's Notice on Deepening the Reform of the Pension Insurance System for Enterprise Employees, before the implementation of the individual contribution system, the employee's consecutive years of service can be regarded as years of contribution. The deemed contribution years can be combined with the actual contribution years to calculate the basic pension insurance benefits. It does not count because of the transfer of the place of social security participation.
