Mid-Qián-lóng-era Qīng physician, regional origin uncertain. Sole securely-attested work is KR3er093 Kuàicán piān 鱠殘篇 (c. 1777), a one-juǎn pharmacological-clinical miscellany that defends a strict zīyīn 滋陰 (yin-supplementing) position against the contemporary vogue for stimulant bǔhuǒ 補火 (fire-supplementing) formulae. Not in CBDB. The text survives in Japanese-imprint recension repatriated through the Hǎiwài huíliú zhōngyī gǔjí cóngshū 海外回流中醫古籍叢書 series.
