May I ask if the high-speed rail ticket from Taipei to Kaohsiung should be booked in advance online? ! Can I buy it directly at the train station temporarily? ! Thanks

It is recommended to book in advance on holidays. On weekdays, you can go directly to the station and buy tickets. It will not be full on weekdays

If you are going from Taipei to Kaohsiung along the Taiwan Strait and have a tour plan in the middle, it is recommended to buy a 3- or 5-day high-speed rail ticket that is exclusively open to foreign tourists. This seems to have to be purchased on the other party's high-speed rail network (you can buy it on the spot, and my photo was taken after buying the ticket at Taipei Station).

Booking train tickets online in advance is the most convenient, safe, and advantageous. Recommended! It is too uncertain to buy temporarily at the train station
