The Qiao Zhou Faxun 譙周法訓 "Legal Instructions by Qiao Zhou", shortly called Faxun 法訓), is a Confucian treatise writen by the Jin period 晉 (265-420) scholar Qiao Zhou 譙周, who has also written a commentary to the Confucian Analects, the Lunyu zhu 論語注. Both texts are only preserved in fragments. The imperial bibliographies in the official dynastic histories Suishu 隋書, Jiutangshu 舊唐書 and Xintangshu 新唐書, and the encyclopedia Yilin 意林 say that the Faxun had a length of 8 juan "scrolls". The Qing period 清 (1644-1911) scholar Ma Guohan 馬國翰 has collected all fragments of the Faxun. They are to be found in his collectaneum Yuhanshanfang jiyi shu 玉函山房輯佚書. A supplement to the Faxun written by Huang Yizhou 黃以周 is wholly lost.
