title: [Life story and works of a doctor in the Ming Dynasty---NI Weide].
abstract: NI Weide, a Ming Dynasty doctor, was rich in knowledge and experience as early as in his childhood. He dipped into all subjects and believed that a Confucianist should also have medical knowledge. He was well trained by family education and became a doctor. After studying Huimin Heji Jvfang at the beginning, he thought current diseases were not in accordance with decoctions recorded in ancient books. He started studying from LIU Wansu, LI Dongyuan and ZHANG Congzheng and became a general practitioner who was especially good at ophthalmology. Among the three famous doctors, he admired LI Dongyuan most and had revised Dongyuan Shixiaofang (9 volumes, compiled by LUO Tianyi) which was published and passed on through generations.
