His principal medical work, the Bǐhuā yījìng 筆花醫鏡 (KR3er009, composed c. 1824 during his Guǎngdōng official career, first prefaced for print by Zhōng Chénglù 鍾承露 in 1834), is a four-juǎn didactic handbook of internal medicine, gynaecology, and pediatrics organised under the zàngfǔ viscera-and-bowels framework with characteristic jūnchén drug-classification tables. The work became a standard text in late-Qīng / Republican-period folk and apprentice-physician training; it was repeatedly reprinted through the Tóngzhì and Guāngxù eras.
