Sunzi: The Art of War is the earliest treatise on military science extant in China. With its rich contents, succinct logic and profound thought, it is a vital part of China’s fine traditional culture and also an important contribution to mankind’s history of military science. In the course of editing this book, several innovations are featured: stories of actual battles have been appended to help the readers better grasp the strategic thought in it. It also uses clear and precise modern English constructions to represent this quintessence of the thought of traditional Chinese military culture.
