I want to know: how to get from Xuanwu Gate to Mutianyu Great Wall in Beijing by bus?

1. Take the Mutianyu Great Wall Tourist Bus (leaving on Saturdays, Sundays and holidays) from Xuanwu Gate Terminal of Beijing Tourism Distribution Center (take 1 Station) and get off at Mutianyu Great Wall Terminal. Go back about 170 meters to Mutianyu Great Wall.

2. Take the subway line 2 (outer ring) from Xuanwu Gate Station (Line 2) B 1 entrance (take 8 stops? ) get off at Exit B of Dongzhimen subway station, go straight to Dongzhimen subway station and change to subway 13 (take 4 stops) and get off at Wangjing West Station (13), and walk to Wangjing West Station (15) and change to subway 15 (take 8 stops) to Nanfa.
