It's my first time to take a train, and I booked the account number of 12306 online. What do you mean I need to check? So you can't book tickets. Oh ~

Now all registered accounts need to be checked at the station counter before they can pass.

If you can't find the tickets booked by others, there are staff in the hall who can ask them.

Different places are different, for example, big cities have high-speed trains, ordinary cars, good tickets, big screen displays after entering the station, or text slogans. Find out what bus you want to take first, and then find out the train number you want to take on the big screen.
