Introduction to Tianbaozhai: Due to the dangerous terrain of the mountain, it became a must-have place for military strategists to set up camp. According to legend, the Red Eyebrow Army once built a wall on the top of the mountain, which was impregnable. There are still stone mortars and other garrison relics on the mountain. Tianbaozhai is located at the mouth of the canyon, and Longpan Road extends along this mountain.
