Do individuals pay social security to calculate seniority wages?

Legal analysis: length of service is the previous statement. The current standard statement is: the number of years to pay social insurance funds. The social security paid by oneself is also counted as the length of service at retirement. Both the individual's payment of social insurance fund and the unit's payment of social insurance fund are regarded as the years of payment of social insurance fund. In other words, whether in an enterprise or as a freelancer, pension insurance is calculated when you retire.

Legal basis: Article 10 of the Social Insurance Law of People's Republic of China (PRC), employees shall participate in the basic old-age insurance, and the employer and employees shall jointly pay the basic old-age insurance premium. Individual industrial and commercial households without employees, part-time employees who have not participated in the basic old-age insurance in the employer and other flexible employees can participate in the basic old-age insurance, and individuals pay the basic old-age insurance premium. The measures for the endowment insurance of civil servants and staff managed by reference to the Civil Service Law shall be formulated by the State Council.
