Lie Yukou (Chinese: 列圄寇/列禦寇; pinyin: Liè Yǔkòu; Wade–Giles: Lieh Yü-k'ou; fl. ca. 400 BCE) is considered the author of the Daoist book *Liezi*, which uses his honorific name Liezi (Chinese: 列子; pinyin: Lièzĭ; Wade–Giles: Lieh-tzu; literally: 'Master Lie'). The second Chinese character in Yukou is written kou 寇 "bandit; enemy"; the first is written yu 圄 "imprison", yu 禦 "resist; ward off", or occasionally yu 御 "drive (carriage); ride (horse); control" (the Zhuangzi claims Liezi could yufeng 御風 "ride the wind"). Lie Yukou was born in the State of Zheng, near today's Zhengzhou, Henan Province. **Source**: [Lie Yukou](https://en.wikipedia.org/wiki/Lie_Yukou) on Wikipedia.
