How much can Xiamen social security refund after three years?

After three years of insurance, you still do not meet the conditions for receiving a pension, and you must pay the pension 15 years. If you have not paid 15 years by retirement age, you can pay it back to 15 years. If you don't want to return it, you can apply for a refund. The refunded part is 8% of the annual payment base, which is the balance of personal account.
