The Lüyuan shigui 律苑事規 is a guide book consisting of ten volumes dealing with Vinaya, compiled in the 2nd year of Taiding 泰定 （1325） in the Yuan Dynasty. It is now included in the Zokuzōkyō 続蔵経. Many scholars have researched the Pure Rules for Chan Monasteries （Chanzong qinggui 禅宗清規）, but academic attention has seldom been devoted to the Lüyuan shigui. There is no research on the editions, structure and compilation of the text.
This paper elucidates three points: 1. the existing manuscripts of the Lüyuan shigui, 2. its structure, and 3. its compilation. As a guide book for the Vinaya school in the Yuan Dynasty, the Lüyuan shigui is of tremendous importance for study of the relationship between the Vinaya and Chan schools.
