If the train ticket booked on Ctrip is certified on-site, you can get on the train directly or you need to be 2 hours in advance

You can pick up the ticket at any time. Usually, you go to the train station to pick up the ticket and then enter the station, so you don’t have to run back and forth.

Is it a train ticket from the mainland or from Taipei? If it is the former, then the G.D train ticket does not need to print the paper ticket on the spot, and directly swipe the ID card to enter the station. For the T.K train, you need to go to the self-service machine at the train station to swipe the ID card to take out the paper ticket, usually 30 minutes in advance Just get to the train station.

Go early, it's best to go early when traveling.

Tickets can be picked up one day in advance<br/>In fact, go to the station, the self-service ticket machine can pick up tickets at any time, there is no rule to pick up tickets 2 hours or how long in advance<br/>It is the same as the train ticket booked online at 12306. <br/>Welcome to click the green "Accept as best answer", thanks
