He used his father’s practice to get medicine from the mountain to his father and he had a keen interest in medicine. When he was young, he took part in the township test and did not pass the examination. He decided to inherit his father’s practice. In practicing medicine, he discovered that the “Materia Medica” edited by the Tang and Song dynasties contained many mistakes, was unclear in classification, and was inaccurate in medicinal properties.
