I have bought a ticket from Yinchuan to Beijing on the 21st, and now I want to change it to one day earlier, how to do it

Whether your ticket can be changed depends on your ticket change policy, you can see it on the order, you can change it yourself, and there is a certain fee.

If you can't change the ticket, you have to refund the ticket and buy it again.

If you bought the ticket through the Ctrip client, you can find the ticket in the order, click to open it, and there is a change in it, just follow the prompts to complete the operation. <br/>However, there may be a high handling fee for ticket changes. Before changing your booking, you should carefully review the relevant fees, and then consider whether it is worth changing for yourself.
