Personal social security into employee social security.

The full name of social security is social insurance, including endowment insurance, medical insurance, work injury insurance, maternity insurance and unemployment insurance. If it is your company's endowment insurance, for example, when you are on the job, you only pay part of your personal account and the unit pays part of your overall account. If it is converted into life insurance, it will be paid by the individual. As long as you work in any unit, the money in the overall account can be transferred to the current unit and paid by the current unit.
