In Chinese folklore, there is a legend that depicts the origins of the black-bone chicken. It is said that the celestial Lu Dongbing (pictured below right, born in 798 A.D.) made pills of immortality on Tiger-nose Peak (below left). Tiger-nose Peak is also known as Two-finger Peak of the Wushan Mountain in Taihe. On the day when the pills of immortality were successfully made, Lu Dongbing invited other celestial beings to the celebration party. When the celestial beings were drinking wine, a pair of wild chickens flew from the forest into the pill-making pool and ate the pills of immortality.
