Early- to mid-Qīng Buddhist monk active at the Shígǔshān 石鼓山 (Héngyáng, Húnán) Chán xuǎnfóchǎng 選佛場. Lifedates unrecorded. Per the preface to his sole extant work, Jīngāng jīng yǎngǔ 金剛經演古 (KR6c0083, X25 no. 495), the work was undertaken in the summer of jǐyǒu 己酉 (most plausibly Kāngxī 8 = 1669, given his probable monastic generation) when he and fellow monks were studying together at Shígǔshān; he found Zōngmì’s Zuǎnyào “concise but obscure” and Zǐxuán’s Kāndìngjì “detailed but unmemorable,” and so combined the two with his own editorial pruning into the present yǎngǔ (“expounding the ancient”) synthesis.
