What do you mean by social security and no social security?

What we usually call social security is comprehensive urban insurance, including five types of insurance:

Namely, endowment insurance, medical insurance, unemployment insurance, maternity insurance and industrial injury insurance.

Both the work insurance company and maternity insurance are paid by the company. Pension, medical care and unemployment insurance are paid by companies and individuals in proportion, so generally we will deduct the "three gold" when calculating wages, which means these three insurance benefits. The so-called "four gold" refers to these three insurances+housing accumulation fund.

Medical insurance, one of the five types of social insurance, is what people usually call medical insurance.

Under normal circumstances, urban comprehensive insurance cannot be paid in installments. But there are also special circumstances, sometimes only one or a few are sent. In some areas, there will be other types of insurance without uniform standards to replace urban comprehensive insurance, such as small town comprehensive insurance, rural comprehensive insurance, migrant workers comprehensive insurance and so on. These types of insurance are also called social security in some areas, but compared with urban comprehensive insurance, the protection is very low, which can basically be said to be retirement insurance. Therefore, it is best to ask what insurance the unit pays first. Is it real social security or fool's "social security"?
