from Beijing Airport (Terminal 2) to Wukesong

Since there is no direct transport, you need a transference. Firstly, you can take Airport Shuttle Bus Line 1 at Gate 13-18 on the 1st Floor, T2 of the airport and then you should get off at Dabeiyao(Guomao) Station. After that, at Guomao MTR Station, you need transfer to subway line 1 which could take you to Wukesong directly.

You can take the airport shuttle bus to reach Xidan and then change to subway line 1 from Xidan to Wukesong Subway Station.
