Xingcheng social security

There are four kinds of social security. I don't know which one you like. We have rural insurance, urban insurance and urban insurance in Shanghai, as well as insurance for foreign employees. Except for foreigners who are insured at the age of 50 and receive old-age subsidies, the rest are 55 years old. You have to pay 15 years to get a pension. If you haven't reached retirement age, you can pay it back.
