From Chiayi to Kaohsiung on February 6, is it difficult to buy a ticket for Taiwan Railway in Chiayi? Can I buy it on the spot? I plan to take Taiwan Express Alishan Line B from Alishan to Chiayi Taiwan Railway Station, and change Taiwan Railway to Kaohsiung. The earliest bus on line b is 9:10, and the journey takes 2.5 hours. If I buy a ticket for Taiwan Railway in Chiayi first, I worry that if I don’t get the earliest bus to go down the mountain, I will be finished. But if you don't buy it in advance, you are afraid that you won't be able to buy the Taiwan Railway ticket on the spot. The 6th also belongs to Taiwan’s Spring Festival travel season. Can anyone with experience answer this question? Appreciate it.
