Massive (373 hectare) park/garden/theme park nearly halfway to Suzhou, at the very end of Line 17, right next to Diantian Lake. The south gate is about two minutes from the station. Apart from the odd bits of nonsense aesthetic drizzled around, it's got your standard green spaces, squares, long promenades, a bike route, snaking brook-side pathways, paddleboat/canoes for hire on the smaller lake, a go-kart track, etc. More importantly, it's got a sweet aircraft carrier packed with a collection of PLA military hardware on display. It's called the National Defense Education Museum. School-kids visit. 50rmb entry fee for the park itself and then a few areas cost extra on top of that. The aircraft carrier is free. The submarine costs 30rmb to board. Oh there's also a submarine.
