The First Half of My Life is an introspective autobiography written by Aisin Giorro Puyi, the last emperor of the Qing Dynasty, in Fushun War Criminals Detention Center. Puyi, as the 12th emperor of the Qing Dynasty and the last emperor of the feudal dynasty in China, ascended the throne at the age of three, legally reigned for three years, and later served as the puppet Manchukuo emperor 13. The First Half of My Life records the process of Puyi's accession to the throne, exile and acceptance of the "transformation" of the new China. It is a memoir, a book of introspection in a specific historical environment. The reason why this name is called is because Puyi wanted to write "My Old Age" in his later years, but unfortunately he didn't get it. All the preserved manuscripts have been compiled into my first half of my life and become my memoirs of my life.
