Which is better, Kaohsiung or Tainan? can only choose one

I think you can go to both places, because it only takes one hour by train from Tainan (Kaohsiung) (slow train), and about half an hour by Ziqiang. <br/>It is recommended to watch lanterns at Lin Department Store/Chikan Tower/Guohua Street/Puji Temple during Lantern Festival in downtown Tainan, walk around and eat delicious food. And these attractions are not too far from Tainan Railway Station, you can walk or take a taxi. <br/>After shopping, you can take the regional train to Qiaotou and visit the Qiaotou Sugar Factory. There are some DIY activities and cycling around the park/meat buns are also delicious. <br/>Afterwards, you can take the train to Kaohsiung, transfer to the MRT and arrive at the Pier-2 Special Zone to see the exhibition, and become a Japanese youth. In the evening, go to Xiziwan to eat delicious food and watch the sunset. <br/>If you really only plan to complete these itineraries in one day, you can go to Tainan in the morning and Kaohsiung in the afternoon, or just play in Kaohsiung, because Kaohsiung has relatively developed public transportation and is suitable for independent travel. If transportation is not a problem, you are welcome to discover Tainan’s delicacies and historical sites! !
