Can't social security and medical insurance be paid in the same city?

You can't. According to China's social insurance system, social security and medical insurance need to be paid in the same city. Social security (including old-age insurance, medical insurance, unemployment insurance, work injury insurance and maternity insurance) is insured as a whole at the place of work or domicile. Social security refers to social insurance, which is a social and economic system that provides income or compensation for people who are unable to work, temporarily unemployed or suffer losses due to health reasons. In China, social security is an important part of the social security system, covering pension insurance, medical insurance, unemployment insurance, industrial injury insurance and maternity insurance.
