Introduction to Xiwu Tiecheng: Zhaolingyan is located to the west of the Five Peaks. The cliff is more than 100 meters high, more than 400 meters long, and the widest section is more than 100 meters. It runs east-west, squatting and entangled, with steep north and south sides. There are many strange rocks and pines on the rock ridge, which are scattered and strange. Looking up from the bottom of the rock, it looks like an insurmountable iron city, so it is called Xiwu Iron City; looking from the Jungfraujoch, it looks like a whale floating in the sea; looking from a distance from Puyang City, it looks like a horse flying in the sky, also known as Tianma Peak.
