Introduction to Ajiao Valley: Ajiao Valley is adjacent to Sangbu Valley and is divided into big Ajiao Valley and small Ajiao Valley. The famous "Eighteen Crossing Rivers" in the ditch has unique scenery and is extremely dangerous, forming the Ajiao Valley. The Jiaogou Grand Canyon has three stone gates that are the most dangerous in the valley. The beautiful Ajiao River twists and turns. After passing through the three stone gates, it rushes out of the canyon and merges into the Tao River, the Yellow River, and even the sea.
