Introduction to Jiulong Waterfall: Jiulong Waterfall is 123 meters high. Nine dragon body patterns are naturally formed on the stone wall, resembling nine giant dragons, hence its name. If the sun shines brightly, rainbows will appear on the waterfall. When people stand in front of the waterfall, they will be surrounded by rainbows. When people walk, the rainbow will follow them step by step. Such an illusory scene is a wonder in the world.
