Ctrip's booking has never been reminded by SMS.

1 1 to 7: 00 the next day, the online ticketing system of the whole railway will not sell tickets to the outside world. Ctrip obtains ticket information from the railway online ticketing system. Even if Ctrip receives the money after 1 1 in the afternoon, the ticket will not be issued until after 7: 00 the next day. Therefore, at 7 o'clock the next morning, there will definitely be no text message about successful ticket purchase. During this period, the train station (and some sales outlets) are still selling tickets, and the tight tickets may be sold out during this period.
