Late-Qīng physician of Lánzhōu 蘭州 (Gānsù), son of 朱序東 Zhū Xùdōng and the second-generation head of the Lánzhōu Zhūshì hereditary medical lineage. Locally famous as the Zhū sānyé 朱三爺 (“Mr. Zhū Three”) because of his pre-eminence in the small Lánzhōu medical community of his time. Documented by his grandson Zhū Tàiyán 朱太岩 in the 1991 preface to KR3er113 Yīxué xīnwù zázhèng yàoyì: famed for the painstaking pulse-diagnosis (taking the pulse repeatedly to ensure accuracy), prudent prescription, attention to dosage even by fraction-cents, and willingness to attend emergency calls at any hour. Supplemented his father Zhū Xùdōng’s eyebrow-notes on Chéng Guópéng’s Yīxué xīnwù (1732). A Liángzhōu jiàoyú Sūn Shòushān 孫壽山 plaque inscribed Dānxī pǐnwàng 丹溪品望 (“Dān-xī-level reputation”) hung in the family’s southern hall in his honour. Not in CBDB.
