Mid-Qīng Cantonese official and amateur physician of Fèngchéng 鳳城 (= Shùndé 順德, Guǎngzhōu prefecture). Jìnshì of Dàoguāng 30 / 1850; Hànlín shùjíshì 庶吉士 thereafter; later xuéshì in Jiāngxī. As a young man during a 1843 convalescence in Hángzhōu from haemorrhoid trouble, he assembled a collection of 700-plus simple medical formulae from the medical literature; in collaboration with the Rénhé hereditary physician 龔自璋 Gōng Zìzhāng (Yuèchuān 月川) and his own Cantonese family connections, he produced and published the KR3er114 Jiāyòng liángfāng 家用良方 (1851) — one of the most successful 19th-c. Chinese popular household-formulary. Best known by his zì Bóchuí 伯垂.
