Yuán-dynasty Buddhist lay scholar (DILA: 否, “not a monk”), native of Sìmíng 四明 (Níngbō). Lifedates not preserved. His own colophon to Jīngāng shū kēshì 金剛疏科釋 (KR6c0054) is dated Zhìyuán jiǎwǔ 至元甲午 = 1294 (the last year of Khubilai Khan’s Zhìyuán reign), and identifies him as a 大居士 (“great householder,” lay donor) attached to the Nánhú 南湖 Tiāntái community at Níngbō under the master Kěmíng 可明. Two extant works: Jīngāng shū kēshì (KR6c0054), an interleaved restatement of Tiāntái Zhìyǐ’s Jīngāng bānruò shū; and the Fǎhuá jīng kēzhù 法華經科註 in 8 juan (X31 no. 606). Both works embody the late-Sòng / Yuán Tiāntái lay-scholarly genre of jiāng shū rù jīng 將疏入經 — interleaving received commentaries with the sūtra root-text for ease of study.
