What does high-speed rail stand by mean?

High-speed rail ticket standby is standby ticket purchase, that is, passengers purchase tickets through official website 12306 or mobile phone client. If they don't have tickets for the required trains and seats, they can submit their own ticket purchase requirements according to the date, trains and seats, and the ticket purchase system will automatically arrange online queuing for standby after prepaid tickets.

When there are saleable tickets for the corresponding trains and seats due to refund or change of tickets, the system will automatically cash the tickets and inform the passengers of the purchase results.

Other knowledge of alternate ticket purchase

When the standby order is successfully redeemed, failed and automatically returned, the notification message is pushed through the notification channel selected by the user (SMS, WeChat or Alipay). When a message is pushed, an email notification will be sent (the user's mailbox must be activated).

After successfully paying the advance payment for standby ticket purchase, the system will continue to try to meet the standby demand for you. If there is a ticket that meets the demand, the system will automatically generate a paid order for you. If the advance payment is greater than the actual fare, the system will automatically return the difference fare. If the seat can't meet your needs, the redemption will automatically terminate on the redemption deadline. If the user terminates or the system automatically terminates the standby, the system will automatically refund the advance payment according to the original amount.
