Legendary Physician of High Antiquity — Jiudaiji

Jiudaiji was a medical master of high antiquity. In the Huangdi Neijing Suwen · Yi Jing Bian Qi Lun (Basic Questions of the Yellow Emperor's Inner Canon: Treatise on Shifting Essence and Transforming Qi), when Qibo was answering questions posed by the Yellow Emperor, he pointed out: “The inspection of the complexion and the pulse — these were treasured by the Supreme Sovereigns (the rulers of high antiquity) and transmitted by the former teachers. In high antiquity, Jiudaiji was commissioned to regulate the complexion and the pulse in order to communicate with the divine intelligence. He integrated them with the principles of metal, wood, water, earth, and fire; with the four seasons, the eight winds, and the six directions — never departing from their regular patterns, yet observing their changes and mutual transformations, in order to perceive their subtleties and to grasp their essentials. If one wishes to know the essentials, they lie precisely in the inspection of the complexion and the pulse.” The Ming dynasty scholar Xu Chunfu, in his Gujin Yi Tong (Comprehensive Medical Survey, Ancient and Modern), held that: “Jiudaiji was a contemporary of the Yellow Emperor and the teacher of Qibo. Qibo engaged in question-and-answer discourse with him, and this was recorded as the Neijing.”
