What is social security? Is it insurance? Where to buy it? Is it an insurance company? What kinds are there?

"Social security" refers to social insurance.

There are mainly five kinds of insurance: endowment insurance, medical insurance, industrial injury insurance, unemployment insurance and maternity insurance.

The management and sales unit is the Social Security Bureau.

The social security that employees participate in is managed by the enterprise, which is social security for employees. There are only two kinds of insurance for freelancers, endowment insurance and medical insurance.

There is a limit to the payment of endowment insurance, which cannot be less than fifteen years. Otherwise you can't retire and enjoy a pension.

Medical insurance payment can't stop halfway, and if it stops, it will lose medical insurance benefits. Only after retirement can you enjoy life for free.
