I paid social security for one month before. Can I cancel my account and open an account again now?

At present, there is no national social security network. As long as you are not in a jurisdiction, you can re-open an account, but an ID card can only be insured once in the same jurisdiction. Social security accounts in different regions can be merged and must be merged, otherwise the social security paid in front will be paid in vain.
