query: Who killed the last emperor of China?
passage: Puyi
Mao Zedong started the Cultural Revolution in 1966, and the youth militia known as the Red Guards saw Puyi, who symbolised Imperial China, as an easy target. Puyi was placed under protection by the local public security bureau and, although his food rations, salary, and various luxuries, including his sofa and desk, were removed, he was not publicly humiliated as was common at the time. The Red Guards attacked Puyi for his book From Emperor to Citizen because it had been translated into English and French, which displeased the Red Guards and led to copies of the book being burned in the streets.[304] Various members of the Qing family, including Pujie, had their homes raided by the Red Guards, but Zhou Enlai used his influence to protect Puyi and the rest of the Qing from the worst abuses inflicted by the Red Guard.[305] Jin Yuan, the man who had "remodelled" Puyi in the 1950s, fell victim to the Red Guard and became a prisoner in Fushun for several years, while Li Wenda, who had ghostwritten From Emperor to Citizen, spent seven years in solitary confinement.[306] But Puyi had aged and his health began to decline. He died in Beijing of complications arising from kidney cancer and heart disease on 17 October 1967 at the age of 61.[307]
