You Xian Ku

You Xian Ku or Youxian ku (Chinese: 遊仙窟 ; translated as "A Visit to a Fairy Cave", "Cavern of the Disporting Fairies" or "Journey to the Immortals' Grotto") is a Chinese tale from the Tang dynasty, written by Zhang Zhuo (張鷟, also known as Zhang Wencheng 張文成) (658–730).

[3] Zhang Zhuo (Chinese: 張鷟, born 658–730 CE), bestowed the honorary name of Wencheng (文成), was a Tang dynasty jinshi, a former imperial censor (御史), and a native of Luze, Shenzhou (now Shenxian 深縣 county, Hebei province).

You Xian Ku is a story of the author's purported first-hand account visiting Heyuan (now Qinghai province, Xinghai county), passing through Jishi (積石) mountain.

He stayed in the fairy grotto and met two women by chance: Cui Shi Niang (崔十娘) and Wu Sao (五嫂), a widow.

The text is written in a mixture of different styles, including pianwen (parallel prose) and bianwen, and it features rhymes and is leisurely in tone.
