What subway lines do i catch to get to Silk market & beijing Zoo Market from the Presidential Hotel?

You can walk to Fuchengmen station to take subway line 2 to Fuxingmen, then take subway line 1 and get off at Yonganli. It is a walking distance from Yonganli to Silk Market. From the hotel to Beijing Zoo market, you can take subway line 2 from Fuchengmen to Xizhimen and then take subway line 4 to Beijing Zoo.
