It elaborates on strategic and philosophic thinking which have been applied widely to various fields, such as military, politics, economy, etc. Its author, Sun Wu, summed up the experience of wars in the Spring and Autumn Period, showing a series of universal laws of military. At last, he put forward an integrated system of military theory. The book is divided into thirteen chapters, and each chapter has a topic. For example, the chapter titled The Strategic Attack tells us how to attack enemies. Sun Wu advocated that we should achieve the biggest success at a possibly minimum cost, and even sometimes made it without war. He pointed out that there were four ways to win a war:the best was political strategy, the second diplomacy, the third force, and the worst attacking a city.
