Lie Yukou is considered the author of the Daoist book "Liezi", which uses his honorific name Liezi (列子; Lièzĭ; Lieh-tzu; "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").
