"Jingkang Biography" is a chronicle historical document written by Li Gang, an important official in the late Northern Song Dynasty. It has extremely high historical value, especially the first-hand record of the "Jingkang Incident" (the Jin army invaded the Northern Song Dynasty in 1127, and Huizong and Qinzong were captured). "Jingkang's Letters" records in chronological detail the entire process of the court's response to the invasion of Jin soldiers, internal debates, military strategies and political actions from the seventh year of Xuanhe (1125) to the second year of Jingkang (1127). It shows the complex political situation of the Northern Song Dynasty at that time and Li Gang's own political opinions and practices.
Li Gang personally experienced the entire process of the Jingkang Incident, and served as Minister of War, You Cheng, and the envoy who stayed on the four walls of the capital. Therefore, the book not only records major historical events, but also reflects his views on the dispute between peace and war at that time and his attitude of concern for the country and the people. The language of "Jingkang's Letters" is simple and true. It details the Jin soldiers' march south, internal discussions within the court, organizational defense, Li Gang's suggestions and court decisions. It is an important first-hand historical material for understanding the politics and military affairs of the late Northern Song Dynasty.
There are three volumes of the current version (there is also a simplified version with four chapters). Although it is different from the original length, its chronology and true description are still of irreplaceable value for studying the Jingkang Incident, the relationship between Song and Jin Dynasties, and the historical image of Li Gang. For readers who like ancient Chinese history, military history and political history, this book is a rare classic that combines serious historical materials with vivid narrative.
