Introduction to Jinlong Gorge: Jinlong Gorge, located between Tianfengling and Cuiping Peak, has been a natural barrier and a transportation hub throughout the ages. The canyon is deep, with cliffs standing side by side, rocks sandwiching the blue sky, and the narrowest point is less than three feet. During the Northern Wei Dynasty, Emperor Daowu sent tens of thousands of troops to cut through the mountains and dig roads here as a gateway for advancing and retreating from the Central Plains. During the Song Dynasty, Yang Ye and his son defended this place with great danger to resist foreign invasion. In Jinlong Gorge, there is an ancient plank road winding in the middle of the cliff, called "Yun Pavilion".
