Which station that I should take if I want to visit Beijing zoo from friendship hotel?

By bus: Walk to Zhongguo Nongye Kexueyuan stop and take bus no. 695, 332, 697 or Special Line 4. Get off at Baishiqiao Dong. Walk east for about 3min to the zoo.

By subway: Walk to Renmin University station to take line 4 to the zoo directly. The zoo right is the name of the drop-off station.
