Introduction to Longtangjiang Waterfall: Surrounded by cliffs on three sides, the canyon is deep and narrow. The mountain stream cascades down from the cliff with a drop of more than 20 meters. It falls straight to the bottom of the pool, like a white rope hanging down, and the sound is like thunder. It is beautiful and spectacular. The large pool at the bottom of the waterfall is unfathomably deep, quiet and blue, and filled with fish. It is a very attractive landscape wonder.
