Zhangren Peak, located in the northwest of Yuhuangding, is shaped like an old man who takes his name on his back. There are several smaller stones nearby that match, so it is also known as "old man and grandson". The stone inscription on the peak has "the first mountain in the world", "Lingxuan Junji", "Zhongtian Independence", "Dongzhu First Ling District", etc., and there are Qianlong's poems and inscriptions: "Zhangren Wuyue from Qingcheng, how to fake the dome. But the world knows this habit, who is commenting on Du Lao."
