Vinaya was introduced into China during the reign of Chia-pin of T'sas Wei Dynasty. After the translation and propagation of several generations, four vinayas and five sastras of the traditional vinaya were established. By T'ang Dynasty, vinaya teachings were completed, and three vinaya schools, i.e. Nan-shan School, Hsiang-bu School, and Tong-ta School were formed. Afterwards, the Hsiang-bu School and the Tong-ta School gradually declined. Only the Nan-shan school, prospered without interruption. This paper investigates the basic context and lineage of the Dharmagupta-vinaya version from the angle of vinaya origin. The emphasis is on vinaya Master Taohsuan's life, learning, integrating different versions, and conglomerating Mahayana and Hinayana vinayas into a new school. This will outline the introduction and evolution of Dharmagupta-vinaya version, the major vinaya thoughts, and the transformation of different vinaya versions and their commentaries.
