Zhāng Yùqīng 張聿青 (míng Nǎixiū 乃修, zì Yùqīng 聿青; 1844–1905) — late-Qīng Jiāngnán physician, native of Wúxī 無錫 (Jiāngsū), active principally in Shànghǎi from the 1880s onward. He was one of the leading Shànghǎi clinicians of the foreign-concession period and stands at the synthesis of the Sūzhōu warm-disease school (Yè Tiānshì 葉天士, Xuē Shēngbái 薛雪) and the Ménghé 孟河 lineage. His disciples included Dīng Gānrén 丁甘仁 (1865–1926) and Cáo Yǐngfǔ 曹穎甫 (1866–1937), through whom his teaching shaped the Republican-era Shànghǎi medical schools. His KR3ep006 Zhāng Yùqīng yīàn 張聿青醫案 was compiled by his disciples in the years following his death and remains a foundational late-Qīng casebook. He himself reputedly burned his case-files three times, intending to write a systematic theoretical treatise during a hoped-for retirement that he did not live to enjoy.
