From xidan street I will go to great wall - mutianyu on dec 24 , how I get the place

It is suggested to take local subway line 1 at Xidan Metro Station to Jianguomen, where transfer to line 2 to Dongzhimen Station. Nearby you can find bus No. 916 or 916快 (express line) to Huairou Bus Station first, get off at Qingchun Lu Beikou, Huairou Bei Dajie or the terminus and then hire a mini-bus to Mutianyu.
