Yi Lüe Zheng Wu Gai Lun(, Introduction of Corrections to Summaries on Medicine) was written around 1545, the 24th year during Emperor Jiajing's reign in the Ming Dynasty, now it has the only copy extant. Some errors and mistakes happened about this book name and its author in some history books and bibliographies: some reference books describe Yi Lüe Zheng Wu Gai Lun and Yi Lüe Zheng Wu (, Corrections to Summaries on Medicine) as two different books, with their own writer Li Xiang and Li Hanyi respectively. In fact, there is only one book, Yi Lüe Zheng Wu Gai Lun and Yi Lüe Zheng Wu is same book. The author is Li Xiang, but Hanyi is his courtesy name that misunderstood as a different person.
《医略正误概论》约成书于明嘉靖二十四年(1545)，现仅存孤本。历代史志书目关于该书名称和作者的著录颇为混乱，有些工具书将《医略正误概论》和《医略正误》立为2个条目，李象、李汉仪亦被分立2条。实际上《医略正误概论》和《医略正误》为同一部书，作者为李象，字汉仪。.
