What if social security is not the only thing?

If you work in a foreign country, you can apply when you leave. After registering with the local social security department, you can transfer it in different places after paying social security in your hometown, and now you can transfer it across provinces.

2. Local social security is not unique.

In the past, workers' medical insurance can be paid at the same time as rural cooperative insurance, and workers' endowment insurance can be paid at the same time as the new rural insurance. This is because the system is not networked and the information is blocked. Now that the social security system is networked, the data can be queried in real time, and it is impossible to pay two social security at the same time.

3. What about the previous one?

Those who have paid the old-age insurance twice before may apply for a renewal and a suspension. You can apply for a refund if you stop the money paid by individuals in that social security account. If you paid two medical insurance in the past, it has been cleared by system comparison. It's just two insurances. I'm going to choose one, and the other one will be terminated.
