Where is 798? How do I get there by bus from the zoo?
Take the subway ring line from the zoo to Xizhimen (there is no N bus from the zoo to Xizhimen, and it takes 15 minutes to walk), take Dongzhimen, take 955, and you can go directly to the gate of 798. It is Ludong. It's very big, and the galleries and studios are scattered. Take your time.
