Generally speaking, the urban swimming pool in Beitai is the first choice because of its stable passenger flow, many teaching courses, good hydrology and water quality and relatively normal price. The swimming pool in Yuan Hang is bigger than that in Beitai, but the water temperature is not good, especially in winter, and there are not many people. Summer afternoon is ok, after all, it's cool. Tiger Terrace is too far away, Tainan is too expensive, and naturally it is too small.
