Shanghai social security has been suspended for two months, and the company has not paid it back. What should I do?

If Shanghai social security is suspended for three months, it is ok for you to pay the suspended payment for three months, mainly depending on whether the current company is willing to help you pay it back or whether you are willing to pay it back personally.

If you stop paying for three months and go to work now, you don't want to pay for the first three months, which is a continuous payment.
