Prices there are relatively cheap and the water is clean. I think it's 20 yuan or 25 yuan. You can get a monthly card and an annual card, and you can take a steam bath by the way.
In addition, the swimming pool in the High School Attached to the National People's Congress is also very clean, as long as 15 yuan. In the middle school attached to the National People's Congress.
These two places are not particularly far from Gong Wei Village, with 5 or 6 stops.
If you are closer, you should go to a nearby fitness center, such as Jade Bird or Shahao, but it is also near Zhongguancun, and the distance is actually similar.
