The Danxia rock wall on the three sides of the Feihong Feihong is surrounded by a nearly 300-degree curved rock corridor. A large waterfall plunges from the top of the 100-meter-high Danxia rock wall, which is spectacular! The wonderful thing about Feihong Feihong is here. The waterfall plunges down from the rock wall and squats above the turtle stone on the ground. Under the sun, it forms a curved rainbow. Beautiful.
