Taohuayuan (桃花源), the Peach Blossom Spring, is a national scenic area in Taoyuan County on the Yuan River upstream of Changde. Its claim rests on geography: the fisherman in Tao Yuanming's famous fable of 421 CE was 'a man of Wuling', and Wuling is the old name of the Changde region, whose Jin-era commandery matched today's city boundaries — the argument the local scenic authority still makes. The area is known for its peach blossom and river scenery. More than thirty places in China claim the same story, which keeps the argument warm. The fable's idiom, shiwai taoyuan, 'a peach spring beyond this world', long ago became the standard Chinese phrase for an earthly paradise.
In 421 CE Tao Yuanming wrote of a fisherman who found a hidden village through the peach blossom and could never find it again. This is the tale, the Changde valley that claims it, and the idiom the story left behind.
