Mutianyu Great Wall has a long history and a splendid culture. Located 70 kilometers away from the center of Beijing, it is one of the famous sections of the Great Wall in Beijing and represents the essence of the Ming Dynasty's Great Wall. The construction of Mutianyu Great Wall has an unique style. For instance, Zhengguan Pass with three watchtowers standing together to form a central watchtower, is rare among the Great Wall sections. To the northwest, there are famous Great Wall landscapes known as Arrow Valley, and Eagle Flying Upside Down. The terrain is steep and rugged, with continuous undulations, resembling a soaring dragon. In spring, the mountain is covered with beautiful flowers; in summer, it is lush and accompanied by the sound of flowing water; in autumn, the mountains are adorned with red leaves and abundant fruits; and in winter, it is covered in white snow, presenting a picturesque northern scenery. Mutianyu Great Wall is renowned both domestically and internationally and is praised as an outstanding section of the Great Wall.
