The Yingde Cave Glass Channel is built of glass. Only the two ends and the plank pillar stand on the rock, and the other parts are hanging above the cliff. The position of the plank is incredibly high. On the top of the head, you can see the steep stone walls on the cliffs. Under the feet, you can see the water flow at the bottom of the cliff. Overlooking the entire hole, you can also see the many odd rocks in the cave, and this is a thrilling and exciting experience.
