[Sun Simiao's voyage to Chu and Shu regions]

During the 4(th)-11(th) years of Zhenguan reign of the Tang Dynasty, Sun Simiao paid a voyage to the regions of Chu (now mostly the Hubei Province) and Shu (now Sichuan Province) for a total of 14 years. In the 4(th) year of Zhenguan, he went to treat the "hydropsy" of Li Gui, the King of Hanyang, hence, the record given as the 9(th) year of Zhenguan by Bei ji qian jin yao fang (Essential Prescriptions for Emergency Worth a Thousand Gold) is not correct. Later, he went to Jiangzhou (now Jiujiang city of Jiangxi Province) to treat Chen Shuping's, the King of Chenxiangdong beriberi due to wind-poisoning. In the 15(th) of July, the 5(th) year of Zhenguan, he himself suffered a swelling pain in his finger when travelling in Shu region, due to a poisonous sting, which was cured by rubbing with the juice from the root and stem of dendelion. In the 7(th) year of Zhenguan, he suffered a facial erysipelas due to over drinking when he was in Neijiang County which was treated by the mayor, Master Li, with various medications to no avail, which was eventually cured by himself. In the 10(th) year of Zhenguan, he treated the Governor of Zizhou Li Wenbo's consuming thirst. He also got a large amount of copper salts in the Counties of Xuanwu and Feiwu nearby. In the 17(th) year of Zhenguan or later, he processed the "Tai yi spiritual powder" in Wei's family of Shu County. After finishing the processing, he returned to Guanzhong (now Shaanxi) at certain period of "August of 17(th) year of Zhenguan", "January of 18(th) year of Zhenguan", or "January of 19(th) year of Zhenguan".
