Introduction to Qingliang Gorge: Qingliang Gorge is a natural fissure in the middle of an entire cliff formed by hundreds of millions of years of weathering and water erosion. It is the only passage leading to Baizhang Cliff and the original oak forest. The gorge is about 30 meters high, 2 meters wide at its widest point, and can only be passed by a single person at its narrowest point. The two gorge walls are curved and intertwined, with only a sliver of skylight. The stone steps are steep and narrow, and they are built hanging on the cliff.
