Legend goes that there used to be ten violently destructive dragons doing wrong in the world.
About 750 A.D., Lu Dongbin, a famous Taoist priest in the Tang dynasty, suppressed nine dragons and left the tenth, a black dragon, remained in the pool. Hence the name Black Dragon Pool. Came into being in 1394, Black Dragon Pool is divided into two parts by a stone bridge. The color of the water in the south pool is green and the north yellow. Although the water of these two parts meets each other, fish in one pool never visits the other one.
