The first time I took the train, I didn't ask anyone ... You have to arrive at the train station, enter the waiting room 40 minutes before the departure (the waiting room of the general train station is on the second floor), and there will be a security check at the door. When the baggage passes the security check, there is a big screen with a lot of train numbers rolling on it, so you can find it by looking at the train numbers on your ticket (be sure to see them clearly). There will be a reminder above that the train of your flight will find the waiting position of your train after waiting in the waiting room number (also look for the train number, don't get the wrong number). Next, wait for the train to arrive at the station for about 5 minutes, and the waiting room will broadcast a reminder to check in. You can follow the instructions to the designated platform (pick up the ticket for investigation), find the carriage of your train (check the ticket on the train), and find your seat number ... Have a nice trip.
