Came here yesterday afternoon and it was packed!
General admission is 30 yuan (roughly $4.60 at the time of this writing). There are some areas where you’ll need to pay extra to get in.
There are temples here, statues, trees, a lake (beautiful view), and a bridge. This is a nice place to take a walk, take pictures, or just sit by the lake, enjoy the scenery, and relax.
I’ll upload more pictures when I get back home :).
