Introduction to Jade Dragon Playing Waterfall: There are pools and waterfalls in Silong River, which flow continuously. Some of the pools in the gorge are dark green and unfathomably deep, some are clear and you can see the fine scales of swimming fish, some are as wide as several feet, and some are as narrow as only one foot. Some of the waterfalls in the gorge fall from the cliff, like the Milky Way hanging from the sky, some fall from the top of the canyon, and flow rapidly; some are as wide as tens of meters, like a curtain, and some are as narrow as a foot, like a thin line.
