Tianjin social security payment, can it be paid across years?

You paid off your social security after leaving your job. If it has been more than three months, it can't be returned. If the payment does not exceed three months, it can still be paid back, whether it is cross-year or not. Moreover, the payment of social security is cumulative, which can be accumulated with the social security paid before, no matter how long. This regulation is unified, and so is Tianjin.
