Introduction to Qiantiao Mountain: The mountain to the north of Leida Shigou is fractured. The vertical joints of the rocks are very clear, and the layers of rocks stand parallel, so it is called Qiantiao Mountain. The cliffs are thousands of feet high, and they are cut into the air like knives and axes, standing at the mouth of the four rivers. Visitors here can't help but sigh at the uncanny craftsmanship of nature.
