Tang Shen-wei lived around the 11th to 12th centuries, with the courtesy name Shenyuan. Originally from Jinyang, Shuzhou (present-day Chongqing, Sichuan), he was born into a family of physicians with a long tradition and had a deep understanding of classical formulas, gaining fame in his time. During the Yuanyou era (1086-1094), he was invited by the Shu commander Li Duanbo to practice medicine in Chengdu, settling in Huayang (then the southeastern suburbs of Chengdu), thus becoming a Huayang local. Although Tang was plain-spoken and unremarkable in appearance, he was wise, sharp, and highly skilled in medicine, with noble medical ethics. He treated patients regardless of their social status, always answering calls, rain or shine. He never charged scholars for treatment, only asking for secret formulas and records as payment, which endeared him to the scholarly community. Whenever he found a formula or medicine in classical texts, he would record and consult on it, thus accumulating a wealth of pharmacological knowledge. This provided favorable conditions for Tang to compile Jingshi Zhenglei Beiji Bencao, broadening his insights. Between 1082 and 1083, after seeing the draft of the book, the Minister of the Left Pu Chuanzheng wanted to recommend Tang for an official position, but Tang declined, continuing to revise and supplement his materia medica work, which was finalized around 1098. The completed 31-volume work reflected the development level of pharmacology in the Song Dynasty. Tang Shen-wei, with his personal effort, completed such a grand and exquisite pharmacological masterpiece, which, after publication, had a significant impact both domestically and internationally.
