Shunyi Hotel, Shunyi Sports Commission, or some gymnasiums, Kim Green Harbor has Bokang Swimming Pool, or Jinjie has many gymnasiums, but gymnasiums need a fitness card to go. The hotel is cleaner, but the cost is more expensive. It is cheaper to get a card than 80 hours. The water of the Sports Commission is leaking and dirty, but you can swim once every 20 minutes ... for 30 hours. Or there is a water park in Ruilin Bay in Nancai, where there are many water sports and swimming pools. I just went there yesterday. There were few people and the water was relatively clean. I just started my business, so I can go there. I can buy a weekday ticket for 88 yuan online.
