Introduction to Qingyu Gorge: Qingyu Gorge, commonly known as Dongmen Lane, is the only way to climb White Rock and enter the cave. There are thousands of walls cut into the gorge on both sides. Between the cliffs, a stone alleyway only two meters wide and about three to four hundred meters high goes up through the cliffs, with stone steps in the middle. When tourists climb the steep stone steps and look up at the sky, only a curved blue line is left, so it is also called "a line of sky".
