If you go to Xiasha, the swimming pool of Zhejiang Sci-Tech University is indoor, open to the public and cheap. I don't remember how many people are outside. The student period is 5 10 yuan.

Usually, cars are parked outside the swimming pool at night ... adults, many children.

I won't go swimming now because of opening to the outside world. Sometimes, it's all children, it looks like a swimming class, and the coach is leading the team.

Sometimes old people ... Hey.
