Ruiyuan Liaison Office is an organization providing education and training services, mainly providing various training courses for primary and secondary school students, including Chinese, mathematics, English, physics, chemistry and other disciplines. As far as I know, Ruiyuan Liaison Office does not provide refund service.
When signing up for the course jointly organized by Ruiyuan, you need to read the terms of the contract carefully, understand the refund policy, and specify the refund terms when signing the contract. If you need to refund the fee, it is recommended to contact Ruiyuan Liaison Office in time and handle it according to its prescribed procedures and requirements.
