佛祖統紀 36.8

36.8

The author remarks: The Book of Jin states that Yang Hu knew his previous life was as a son of the Li clan and was able to retrieve the gold ring he used to play with. Now, the statement here that in a previous life he built this monastery refers to the life before his previous life. In the world, the retributions of sin and blessing do not err; how could one not take this as a mirror? That Hu was able to know his previous lives is what Buddhism calls the supernormal knowledge of past lives (pūrvanivāsānusmṛti-jñāna). Hu must have studied Buddhism and attained results, manifesting in bodily form in the world.
