Zhang Zhongjing Temple is located in the Cai E Middle Road. Zhang Zhongjing (about 150-219 A.D.), a famous doctor in the Eastern Han Dynasty, was honored by medical specialists after the Song Dynasty as Medical Sage. In the Ming and Qing Dynasties, a Memorial Temple to the Medical Sage was built in his hometown Nanyang, Henan Province to commemorate his accomplishments. His book Treatise on Exogenous Febrile and Miscellaneous Diseases laid a foundation for the development of clinical medicine in China.
