cannot. Only full-price tickets may be refunded and changed for free, and discounted tickets are generally charged. There are instructions on the fees for refunds and changes when buying tickets.

Hello, now that the epidemic protection period has passed, not all air tickets can be rebooked. If you can rebook, you can log in to the Ctrip client again, click on the lower right corner - My - All Orders to enter the air ticket order, and then click [ Refund and Rebooking Policy] Check whether your ticket can be rebooked and the fees incurred. After confirming that it is acceptable, click "Change" to operate. <br/>If it can help you, please click the green "Accept", thank you.

Tickets purchased before January 28 (not included) can be refunded or changed free of charge, otherwise a refund or rescheduling fee will be charged in accordance with the general rules, unless it is an involuntary refund due to flight cancellation.
