How do foreigners handle social security in different places?

Legal analysis: there are two ways to handle social security in different places. The first one only needs one employer. The employer may pay social insurance to the social insurance department within 30 days of establishing labor relations. The second type is handled as a flexible employee and needs to be registered by itself.

Legal basis: Article 58 of People's Republic of China (PRC) Social Insurance Law. The employing unit shall handle social insurance registration for employees within 30 days from the date of employment. If the social insurance has not been registered, the social insurance agency shall verify the social insurance premium it should pay. Employees-free individual industrial and commercial households who voluntarily participate in social insurance, part-time employees who do not participate in social insurance in the employing unit and other flexible employees shall apply to the social insurance agency for social insurance registration. The state establishes a national unified personal social security number. Personal social security number is a citizen's identity number.
