Qiao Zhou Faxun 譙周法訓 "Legal instructions by Qiao Zhou", shortly called Faxun 法訓), was a Confucian treatise written during the Jin period 晉 (265-420) by Qiao Zhou 譙周 (199-270), courtesy name Yunnan 允南. Qiao also wrote a commentary on the Confucian Analects, Lunyu zhu 論語注. Both texts are only preserved in fragments, while Zhou's memorial Chouguolun 仇國論 "About inimical states" has completely survived.
The imperial bibliographies in the official dynastic histories Suishu 隋書, Jiutangshu 舊唐書 and Xintangshu 新唐書, and the encyclopaedia Yilin 意林 say that the Faxun had a length of 8 juan.
The Qing-period 清 (1644-1911) scholar Ma Guohan 馬國翰 (1794-1857) collected all fragments of the Faxun. They are to be found in his series Yuhanshanfang jiyi shu 玉函山房輯佚書.
