華佗
Historical sources say that Hua Tuo rarely practiced moxibustion and acupuncture. The first mentioning of acupuncture in Chinese literature appeared in the "Huangdi neijing". Acupuncture needles made of gold were found in the tomb of the Han King Liu Sheng (d. 113 BCE). Some stone-carved depictions of acupuncture date to the Eastern Han Era (25–220 CE). Hua Tuo also wrote about the allegedly life-prolonging exercises of calisthenics. In the 2nd-century-BCE medical texts excavated from the Mawangdui, illustrated diagrams of calisthenic positions are accompanied by descriptive titles and captions. Vivienne Lo writes that the modern physical exercises of taijiquan and qigong are derived from Han-era calisthenics.
