Where is Huairou swimming recommended, online, etc.
Huaibei University of Technology has a swimming pool, and few people have clean water. My friend has been there. After all, it is a national university venue, and the price should be more affordable than Kempinski and Kuangou. However, today, fitness is everywhere, the water is not very clean and there are many children. The only good thing is that you can exercise and swim.
