Introduction to Orangutan Valley: Historically, it was the road to climb the main peak of Huashan Mountain. According to legend, King Zhao of Qin, Emperor Wu of Han, and the poet Li Bai all passed through this ditch to climb the mountain. In 1949, when the Eight Warriors of the Chinese People's Liberation Army outsmarted Mount Huashan, they passed through this ditch and climbed to the north peak of Mount Huashan. There are lush trees and beautiful peaks and cliffs in the Orangutan Valley. When you enter the ditch, you can see the whole view of the Huashan Cactus to the west.
