I paid social security for eight years, and now I don't have it. What will happen?

Of course, as long as the social security contributions are accumulated to 15 years by retirement. Intermittent does not affect, but the payment period is less, and the pension will be less then. Even if it is not 15 years in the end, it can be paid in one lump sum or returned to social security.

If you want to make up, you can pay it in one lump sum when you retire. The amount of payment is related to the local social security base of the year, depending on the situation in your city.

Best wishes.
