Dài Sīgōng 戴思恭 (zì Yuánlǐ 元禮, often referenced as Dài Yuánlǐ 戴元禮, c. 1324–1405), early-Míng physician and imperial-court medical official. The principal pupil of 朱震亨 Zhū Zhènhēng (Dānxī) in the YuánMíng transition, Dài inherited the full Dānxī-school yīn-supplementation doctrine and was responsible for its early-Míng imperial-medical transmission. Served as imperial physician at the Hóngwǔ 洪武 and Yǒnglè 永樂 courts; the Míngshǐ records his successful treatment of the future Yǒnglè emperor in his youth. The mid-Míng 汪機 Wāng Jī and 王諷 Wáng Fěng 1534 cut of KR3eq026 Tuīqiú shīyì 推求師意 attributes the work to Dài, claiming that Dài alone among Zhū’s pupils míng huì 冥會 (mysteriously-comprehended) the master’s clinical intention rather than merely his words. Modern scholarship treats the attribution as plausible but underdetermined — the Tuīqiú shīyì may represent a longer chain of post-Zhū discipular elaborations of which Dài is the named-but-not-sole author.
