Northern-Sòng monk-philologist of Jīngyánsì 精嚴寺 (a Liǎngzhè monastery, name elsewhere associated with Jiāxīng and Húzhōu regions). Lay surname, native place, and lifedates not preserved.
His one work is the three-juan Shàoxīng chóngdiāo dàzàng yīn 紹興重雕大藏音 (KR6s0016, C1169) — originally titled by him Jīngyán xīnjí Dàzàng yīn 精嚴新集大藏音 — a Buddhist phonological apparatus organized by Chinese radical, treating difficult and miscopied characters in 174 canonical sutras. Composition spanned over two decades: begun Xīníng 3 (1070), completed Yuányòu 8, 10th month (November 1093). The work was subsequently incorporated into the Sòng Shàoxīng 紹興-era (1131–1162) recutting of the canon, from which the modern title derives. Preface by Liǔ Yù 柳豫 dated Yuányòu 9, 4th month, 5th day = 21 May 1094.
The work is structurally innovative as the first surviving Chinese Buddhist yīnyì with dictionary-style radical organization — anticipating the radical-organization principle that would later become standard in Chinese lexicography. It is also a primary preservation site for fragments of the lost early-Sòng Zhòngjīng yīn 眾經音 of Guō Yí 郭迻.
