Why does 12306 always show that the ticket information has expired when buying tickets?

Network delay, it is also possible that the tickets have been sold out, or there is no payment within 40 minutes after the ticket is released, so it is automatically cancelled.

How to buy tickets:

On the home page 12306, add a ticket entrance and click Enter.

Log in to your personal information. If you don't have an account, there is a quick registration button below the login button. You can register directly with your mobile phone number.

You can see that round-trip query is provided, and round-trip query can be completed at the same time if necessary. You can choose between ordinary tickets and student tickets.

Click on the passenger selection, and you can only buy tickets for up to 5 people at a time.

But pay as soon as possible within the time, otherwise the order will be easily cancelled.

Solution:

Exit and re-query, and new information will appear.

Refresh more, just quit and query again.

Re-order and pay as soon as possible to avoid automatic cancellation without payment within 40 minutes after the ticket is issued.
