There is a place in Huangchuan Three Gorges that is as flat as a knife. A huge stone suddenly spews out from the wall, shaped like a dragon head. A waterfall spews out from the dragon head's mouth, hanging straight down in the air, all year round. Longquan Gorge got its name from this. The flying dragon plays with the pearl, and the waterfall falls straight down three thousand feet. It seems like the Milky Way falls from the sky.
