The new edition of last emperor Puyi's autobiography - which includes an account of the cover-up surrounding the death of his adulteress empress' baby - hit mainland bookshelves this weekend. The book, an updated version of From Emperor to Citizen, has an additional 160,000 words. It begins with Puyi's imperial family and his early years and ends when he receives an official pardon and settles down in Beijing as an ordinary citizen. He started preparing the book when he was in jail as a war criminal, and there is a tone of remorse for his past as an emperor. In 1960, then premier Zhou Enlai told Puyi the book was valuable as it reflected the Communist Party's success in reforming the last emperor. The book was not published until 1964 after undergoing three drafts. Historians and famous writers, such as Lao She , fine-tuned the book. The 1964 version was translated into a dozen languages and 1.87 million copies were printed. In 2004, publisher Qunzhong Publishing House found the misplaced drafts that are now included in the complete version. In the chapter about Empress Wan Rong , Puyi discloses that her brother, for his own personal benefit, introduced her to a Japanese military officer. She subsequently had an affair with the man. Puyi was oblivious about the adultery until the empress was close to giving birth. The child was thrown into a boiler soon after birth but the empress was left with the impression the baby was being looked after outside the palace. The new version also restores a section on how Puyi lied at the International Military Tribunal for the Far East in 1946 in Tokyo, denying he wrote a letter to a Japanese general asking the latter to help restore him to the monarchy in the early 1930s. The section details the debate between lawyers representing Japanese war criminals and Puyi, and the last emperor's inner thoughts and anxieties. The new version's editor, Meng Xiangrong , said in an article that before publishing the 1964 version, historians had stressed that 'the parts on international relations and war criminals reform policy must be cautiously treated so that the book won't have any possible side effects and can better serve politics'. The new version also includes a section on Puyi's divorce from fourth wife and last concubine Li Yuqin , who in one letter made Puyi feel 'it seems that I have had a wife for the first time in my life'. But, they still parted ways, though she visited him in prison five times. Puyi's rule, which lasted only three years, ended in 1911 when the Qing dynasty was overthrown. But he was enthroned by Japanese invaders in China as a puppet emperor in the early 1930s. After the Communist Party took over power in 1949 he was put in jail until 1959, when he received an amnesty. He died in 1967.
