In 1954 he devoted his practice entirely to acupuncture based on the classical texts: Huangdi Neijing (Suwen, Lingshu) and the Nan Jing. He was a doctor, author, teacher and scholar of the classic texts of Chinese Medicine (acupuncture-moxibustion). Much of his life's work revolved around translating and adding his own commentary to an unmolested Tang Dynasty copy of the Huangdi Neijing (Yellow Emperor's Internal Classic) from an ancient script into the French language.
