Booking train tickets online has shown that the payment is successful, but there is no text message. I wonder if I have to go to the window to get the ticket?

If you buy a bullet train or a high-speed train, you can swipe your ID card to get on the train. If it is another train, you must pick up the ticket. If you don't receive the message, you can write down your order number. In addition, after the reservation is successful, an email will be sent to the mailbox you used when registering. You can see if you have received the mail!
