High-speed rail travel information prompts how to change the visa.

High-speed rail travel information suggests that you can change your ticket in the following ways:

1. Online return. For those purchased on 12306 website, you can press the "Refund" or "Change" button; If you buy from other websites, you need to refund or change the ticket first, and then go through the formalities of refund or change the ticket.

2. Offline return. Buyers only need to bring their ID cards to the high-speed railway station Ticket Hall, regardless of whether the tickets have been taken out. It should be noted that offline returns can only be processed once.

I hope the above information can help you solve the problem. Please feel free to let me know if you have any other questions.
