Wu Qian (1689~1848), courtesy name Liu Ji, was a native of She County, Anhui. He was a renowned physician during the reigns of Emperor Yongzheng and Emperor Qianlong of the Qing Dynasty and once served as the Right Court Judge of the Taiyiyuan.

As an imperial physician, Wu Qian often attended to the emperor. In the early spring of February in the fifth year of Qianlong's reign (1740), Emperor Qianlong contracted a common cold. Wu Qian, Chen Zhijing, and other imperial physicians "carefully treated him with diligence, and the effect was very rapid," leading to the emperor's quick recovery. As a result, Wu Qian and others were rewarded. During his service in the palace, Wu Qian received such favors multiple times. Emperor Gaozong (Qianlong) held him in high regard, once telling his close ministers, "Wu Qian excels in both character and learning, unlike ordinary physicians. You should respect him."

In the fourth year of Qianlong's reign (1739), Emperor Qianlong ordered the compilation of medical texts, appointing Wu Qian and Liu Yuduo as chief editors. As a chief editor, Wu Qian made significant contributions to the completion of the *Yizong Jinjian*. Wu Qian believed that medical classics and various medical texts from past dynasties suffered from issues such as "obscure language, transcription errors, being broad but not precise, or being miscellaneous and inconsistent." He proposed that these should be "corrected and annotated, distinguishing the merits and flaws of various schools."

Wu Qian revered the theories of Zhang Zhongjing. While compiling the *Yizong Jinjian*, he referenced the works of over 20 medical scholars who studied the *Treatise on Cold Damage Diseases* and the *Synopsis of the Golden Chamber* before the Qianlong era. He annotated the original texts of these two classics line by line, compiling the annotations and interpretations of various scholars into the *Revised Complete Works of Zhang Zhongjing: Annotations on the Treatise on Cold Damage Diseases* in 17 volumes and the *Revised Complete Works of Zhang Zhongjing: Annotations on the Synopsis of the Golden Chamber* in 8 volumes, placing them at the forefront of the *Yizong Jinjian*.
