In Jiangxi's Gaoan County there was a young man by the name of Yang Gui. Now Yang Gui was a slim and extremely attractive nineteen-year-old. He was mild in manner, compliant by nature, and never known to refuse sexual advances of any sort.
One summer's day he was bathing in the village pond when a drake flew up at him from the water and bit him on the buttocks. The drake then whacked Yang with his tail and made humping movements over Yang's buttocks. Yang tried to fend off the duck, beating it repeatedly, but the duck persisted. It Wasn't long before Yang had beaten it to death. When he examined the limp body floating in the water, he saw protruding from among the tail feathers a fleshy stalk. Around the stalk the water was murky with some sort of emission.
The locals thought this episode absolutely hilarious, and from then on Yang Gui became known as the Duck's Lover.
