Introduction to Qinren Tunnel: Located at the end of Shaoren Stream, it is 153 meters long, has an arc-shaped vault, straight vertical walls, and can be viewed from both sides. The spring water in the cave never dries up all year round, and the wind blows away the smoke. The north entrance faces steep cliffs and winding stone paths. From the south entrance, you can see the towering peaks, lush and ancient colors.
