After the resignation of the original unit, what should the social security bought by the new company do in different places?

I personally know that social security is calculated on the basis of accumulated years. At present, as long as it is a province, it should not be a big problem.

It's just that the rules of medical insurance are harsh.

Of course, if you are really worried about this, you have to go to the local social security bureau and medical insurance bureau to learn about the relevant policies and see if there is any real impact. If there is, there may be some remedies that may relieve your worries.
