The son of a medicine farmer in the mid-Ming Dynasty, under the background of "the mature official medical system" and "the boom of folk medical skills", grew from a rural boy familiar with herbal medicine to the judge in charge of the imperial hospital. In the process of integrating folk prescriptions and classical medical theory and breaking through class barriers, he understood that "physicians are not only inheritors of skills, but also practitioners who practice medicine and protect people's livelihood", completing the growth and transformation from "observers of nature" to "pioneers of medical ethics".
