Beijing University for Nationalities, Shen Jing Road, Doudian (next to G 107): If you are talking about this address, you can't get there by subway ~ Even if you take the subway Fangshan Line, you have to take the "Zhuozhou 19 Road" to "Qilidian Village" to get there ~
If you are talking about Minzu University of China, take Metro Line 4 and get off at Weigongcun Station and walk south, or take Metro Line 4 or Line 9 and get off at National Library Station and walk north ~
Hope to adopt ~
