Get off at No.67, Zhixia Hutong, Beijing West Railway Station, get off at ***6 Station, cross the overpass and walk 200 meters east to Baolong Building on the north side of Wanliuqiao.

Or take Line 9 (Beijing West Railway Station, under Liuliqiao, 2 stops), change to Line 10 (northeast exit of Jijiamiao B, 5 stops), get off and walk 720 meters north to 2-7 18 on the 7th floor of Baolong Building.
