Is there a roller skating rink near Xizhimen, Beijing? And a swimming pool. Just asking. Accusation. It is better to have been there recently. thank you

Either it's the moon altar or there's nothing else except these two.

If you swim, there is a twelve-constellation gym in Chegongzhuang North Street, which has a swimming pool, but it is a bit dirty. Personally, I think so . There should be a swimming place near Jiaotong University.
