Registration & Payment
Registration is considered complete only upon receipt of the full conference fee. A confirmation email will be sent by the organizers upon successful payment.
Please note that the Indico payment system only accepts Visa, MasterCard, and JCB cards issued outside of mainland China. Payments through Indico will be processed in Hong Kong Dollars (HKD). An official payment receipt will be issued and emailed to you as soon as possible by the authorized agency designated by the Local Organizing Committee (LOC).
For participants affiliated with institutions in mainland China, please DO NOT use the Indico payment system to pay your registration fee. Instead, scan the QR code provided at the end of this page to complete the payment using WeChat Pay or Alipay. The amount will be converted to Chinese Yuan (CNY) at a fixed exchange rate of ~0.94. An official fapiao (Chinese tax invoice) will be issued after the payment is received.
If you are unable to complete the payment using either method or encounter any issues, please contact the LOC at lidine2025@ihep.ac.cn.
