 Ranka (legend)

Lanke or Lankeshan (爛柯(山), Lànkē(shan), Lan-k'o (Shan); "(The Mountain of) the Rotten Axe Handle" in English), is a Chinese legend which has been compared to that of Rip Van Winkle, although it predates it by at least 1000 years.The exact date of origin of the legend is unknown, but it has literary antecedents from the 5th century AD, and the "rotten axe handle" plot element was certainly present by an early 6th-century version.
