Introduction to Waterfall Pearl Listening to the Rain: Not far to the south of the ancient cypress Longpan, there is a row of cliffs. The cliffs are a hundred feet high and appear to be hanging upside down. There is a deep spring below with extremely clear water. The water on the cliff pours down like a waterfall and falls into the spring. It stirs up and down, splashing silver and jade. The sound is like beads, like a mountain rain coming in a hurry, making people feel like listening to fairy music.
