In the Tendai Reio Hondenshu (天台靈應圖本傳集), a work alleged to Tenkyo Daishi Saicho (最澄, 766-822) of Japan, there is a piece titled “You-tiantaishan-fu (遊天台山賦)”, which consists of “You-tiantaishan-fu”by Sunchuo ( 孫綽, 314? 371?), and two-line commentary inserted among the former. This piece, as this article is to prove, can be regarded as quotation from the oldest version of the Wenxuan annotated by Lishan (李善) . This discovery is not only to provide a precious resource for the research of Wenxuan that has a long and excellent tradition in Chinese literature studies, but also to stress the importance of the Tendai Reio Hondenshu in order to direct the attention of Buddhist researchers to the present collection.
