Excuse me, how can I get from Beijing West Railway Station to the American Embassy in China (No.55 Anjialou Road)?

Beijing West Railway Station-Anjialou:

Take bus No.673 at the north exit, go to Hujialou North, transfer to bus No.402 or 420, get off at Liangmaqiao East, get off at the first traffic light, and walk east to the American Embassy in China (No.55 Anjialou Road).

Another plan is to take the subway, which is one more time than the previous plan, but the subway time is guaranteed. Take bus No.2 1 or No.320 at the east bus stop of Beikou to the Military Museum, then take the subway No.21to Guo Mao, then take the subway No.2 10 to Liangma Bridge, and the northeast exit goes east to the first traffic light intersection.
