The study on the lineage of Hui yuan has been unvalued in the studies of Chinese buddhist history. Actually, Fashen, the disciple of Huiyuan, writes the Huayan Jingshu (31 volumes). Kuaiji Shenxiu, the disciple of Fashen, writes the Huayan Jingshu (30 volumes) and Miaoli Yuanchengguan (3 volumes). However, there’re still some problems unsolved, such as whether Fashen is the disciple of Huiyuan, or whether the Huayan Jingshu and Miaoli Yuanchengguan are the works of Kuaiji Shenxiu. This paper attempts to solve these problems, and demonstrates the lineage of Huiyuan’s attention on the interpretation of the Avataṃsaka Sūtra at the same time.
