Opening this epic strategy, you will step into a feast of wisdom that spans time and space. This book takes ancient history as the stage, selects classic strategy stories from the Spring and Autumn Period and the Warring States Period to the Ming and Qing Dynasties, and re-constructs the contingency techniques that changed the direction of history from a modern perspective. Whether it is Sun Wu's battlefield wisdom of "not tired of deceit" or Zhang Yi's diplomatic strategy of "continuous horizontal and vertical defeat"; whether it is Zhuge Liang's "empty city strategy" psychological game, or Liu Bowen's imperial power tactics of "retreating to advance", this book will take you through the fog of history and directly penetrate the essence of the thinking of wise men.
