It was always a historical disputed case on the hypothesis of Zhang Zhong-jing, a famous doctor in the Eastern Han Dynasty (25 - 220 A.D.), was once the governor of Changsha. Based on large amount of studies on archival materials combining with unearthed relics, it can be fully ascertained that Zhang Zhongjing had been the governor of Changsha with his tenure in the year of Jian'an 7th to 10th or 12th year, ie, from 202 A.D. to 205 or 207. During this period, Zhang insisted to have clinical practice and wrote his Shang Han Za Bing Lun (Treatise on Exogenous Cold and Miscellaneous Diseases), exerting profound influence on later generations. The Zhang-gong ci (memorial ancestral temple for Mr. Zhang) was built in Changsha city in the Qing dynasty to commemorate him and the medical sage Zhang Zhong-jing is recalled and venerated deeply by the people in the city even today.
