Black Dragon Pool, located at the southern foot of Longquan Mountain, is about 10 km away from Renshou County, Sichuan Province. It is known as "the largest lake in western Sichuan" with a storage capacity of 360 million cubic meters. On the surface of 236 square kilometers, more than 80 islands are dotted on the water like bonsai. Blue waves are vast and have been listed as provincial-level scenic spots.
Legend has it that a long time ago, a black dragon made waves here, endangering the poor. Later, in the heroic pursuit of the two sisters, the dragon head was cut off and trapped in a layer of rock, and never resurrected to do evil.
