Hello, the process of a Chinese public education refund is like this. I need the original agreement you signed at that time, the original receipt and a copy of your ID card, and go to the sub-center where the payment was made at that time for a refund. The original card has not been returned for more than 30 days. If it is more than 30 days, you need to leave a separate bank card. Both refund methods require you to fill out a refund application form at the front desk. General payment is 15-30 working days.
If in doubt, please consult the public education enterprises in China.
