Last time I went, the address provided by the service staff was inaccurate, so I walked a long way.
When you get out of Shuangqiao subway station, go south, cross the road (be sure to follow the road) and walk 300 meters west. The signboard of the light box is not very bright, so you can only see the distance when you walk to the door.
Indoor machinery and the like are relatively new and the venue is not bad.
The only problem is that it's a little expensive.
