The Great Wall is located in the Huairou District. It is a rare part of the Great Wall. In the northwest, there are common scenic spots such as "Buffalo Corner", "Arrow Buckle" and "Eagle Flying Back". The potential is steep and undulating, such as the dragon flying. Under the beacon tower at the height is a narrow wall, swaying down the road that has been going down the mountain, and farther away is the Beijing city where Pingyao is safe and unguarded. The blue lake is Yanqi Lake.
