Users who need to cancel courses or refund tuition fees after registration can apply for a refund within 15 days after registration, and will not be accepted after 15 days. If users apply for a refund, they need to provide relevant application materials, including ID cards, registration forms, payment records, etc. The refund can only be completed after verification and confirmation.

It should be noted that the refund amount may be different due to factors such as the refund time.
