Cixi controlled the late Qing Dynasty for 47 years by "listening to politics behind the curtain", launched three palace coups, and deposed the emperor twice. She reused Han ministers to promote Westernization, but missed the opportunity for reform due to the obstruction of conservative forces; her support of the Boxer Rebellion triggered the Eight-Power Allied Forces to invade China, and she was forced to sign the "Xinchou Treaty". This master of maneuvering struggled to survive among the great powers, using traditional political wisdom to maintain the crumbling empire. His life trajectory reflected the final struggle of the feudal system.
