Is water curtain cave, Hongyadong, the red cliff dripping green?

No, Didi Cui means the degree of green, as if falling into the water, so Hongyan Didi Cui is a demonstration scene, not water curtain cave. Hongyadong, formerly known as Hongyamen, is one of the gates of ancient Shu. It is located in Cangbai Road, Jiefang North Road, Yuzhong District, Chongqing, and the riverside area where the Yangtze River and Jialing River meet.
