How can I take the Yuquan Road subway bus from Beijing Institute of Civil Engineering and Architecture at Exhibition Hall Road 1 Xicheng District, Beijing?

The above answer is too much trouble. You take the subway. Go to the zoo. If you go to Xizhimen. Is to go far. There is also a bus to the zoo. Get out of the subway. I don't know that entrance, but it's Planetarium Street. Then you go along this road. Go to the zoo, FKC. Turn right. Only a few steps away. . It's quite close.
