I know there is a swimming pool in the headquarters of Central South University, with two pools, big and small. It's good. It's usually 7 yuan an hour at night. A game lasts about two hours. 15 yuan.

It is the cheapest in the morning, the most expensive in the afternoon and the most expensive at night. Good inside, good water, good companions and good conditions.

Some people teach swimming lessons. Generally, you can learn to swim around 300 yuan, and you can also get a 10 swimming ticket.
