Dí Rénjié 狄仁傑 (630–700), zì Huáiyīng 懷英, Táng official and chief minister under Wǔ Zétiān 武則天, posthumously enfeoffed as Liánggōng 梁公 (Lord of Liáng), hence the title Dí Liánggōng 狄梁公. Famed as an upright magistrate and judge, he also figures in medical-historical anecdote — referenced in the preface to Huīhòu fāng KR3ed151 — for an acupuncture cure performed (according to legend) on the son of a wealthy household, and his refusal of the offered thousand-gold fee; the episode is cited as an exemplum of judgement-of-character and the principled disinterestedness of the physician-statesman.
