With the core of "state affairs are family affairs, and the world is the people's hearts", this book shows the alienation of human nature at the peak of power and the survival resilience of the people at the bottom through the thirty-year process of a unified dynasty from prosperity to decline and from chaos to rule. Behind the palace struggle is the dilemma of the system, the end of the party struggle is the devastation of people's livelihood, and the border war reflects the conflict of civilizations and the survival of ethnic groups-all grand historical narratives ultimately end in the struggles and choices of individuals. Sixty years after the founding of the People's Republic of China, the third generation emperor Yongxi reigned for thirty years from Yongxi's 30th year to Yongxi's 60th year. During the thirty years, the structural contradictions that had been covered up by peace broke out in an all-round way. Covering two generations of emperors, three large-scale border wars, and four national natural and man-made disasters.
