Introduction to Jianlong Waterfall: Jianlong Waterfall, also known as Tantou Waterfall, is named after the ancient village of Tantou in the upper reaches. Jianlong Waterfall is open for a limited time every year, just like seeing a dragon in the field (it only appears every spring), hence the name. Jianlong Waterfall falls from the cliff at an altitude of 580 meters to the bottom of a ditch at an altitude of 260 meters. The drop is as high as 320 meters. The maximum flow of the waterfall can reach 3,000 cubic meters per second. It looks like a flying dragon in the clouds, with a powerful voice and a rainbow of energy. Known as "the first waterfall in the Central Plains", it shows a vivid picture of "the mountains are beautiful because of the water, and the water is strong because of the mountains".
