Whether Fuqingzhunuke (Fu Qingzhu's Obstetrics and Gynecology) and other books signed by FU Shan were written by himself or not is always a controversial problem. The content of Fuqingzhunuke is similar to that of Bianzhenglu (Syndrome differentiation record) of CHEN Shi-duo. For some reason, it is also said that the medical work of CHEN Shi-duo was written by FU Shan. However textual research shows that, CHEN Shi-duo had never met Fushan at all, so the medical work of Chen Shi-duo had not come from FU Shan. Some scholars believed that FU Shan concealed his name in his medical work due to his need to struggle against the Qing dynasty., but in fact, FU Shan had never lived incognito in his medical practice., The Fuqingzhunuke was edited with adjusting some sentences on the basis of Bianzhenglu The later copy editions of Fuqingzhunuke actually were supplemented and changed some content, and the author in some copies was altered to another name as well. Distinguishing the fake and genuine of Fuqingzhunuke necessitates making a comparative study of the style of writing through other works of FU Shan to arrive at a reliable conclusion.
