This book uses the Spring and Autumn Overlords with unique charisma as key clues to describe their impact on the Spring and Autumn history and even the changes and integration of Chinese civilization. The experiences or achievements of each of them reflect the major turning points in politics, economy, military, society and thought in the Spring and Autumn Period. The book mainly tells the experiences and achievements of the four overlords Duke Huan of Qi, Duke Xianggang of Song, Duke Wen of Jin, and Duke Mu of Qin, as well as their important influence on the history of the Spring and Autumn Period. When Duke Huan of Qi changed, he respected the king and fought against the barbarians, and the Xia of the Central Plains formed an offensive and defensive alliance; when Duke Xianggong of Song changed, the old war rituals collapsed, and the way of war suddenly became fierce; when Duke Wen of Jin changed, a great power hegemony was established, and new types of politics emerged one after another; when Duke Mu of Qin changed, peripheral countries gradually emerged, and the future Great Qin Empire began to take shape. This book provides a detailed ethnic origin and cultural character analysis of each of the great Spring and Autumn countries. It is based on historical books and supplemented by many cutting-edge academic results and archaeological discoveries, striving to comprehensively and truly present the turbulent Spring and Autumn era.
