Táng-period philologist, of Fùchūn 富春 (modern Fuyang, Zhejiang); active in the Shàngyuán era (674–676) of Gāozōng. He produced the standard Táng-period augmentation of Gù Yěwáng’s 顧野王 Yùpiān KR1j0022 — a recension known historically as the Shàngyuánběn 上元本, which substantially enlarged the Liáng Yùpiān’s headword count and was the version most widely transmitted until the Northern-Sòng comprehensive revision of Chén Péngnián 陳彭年 et al. (Dàzhōngxiángfú 6, 1013). Beyond his work on the Yùpiān, no biographical detail survives.
