Located in Changchun, the capital city of Jilin Province, the Puppet Manchurian Palace Museum is a palace-relic museum built on the remains of the palace of Aisin Gioro Puyi, the last emperor of the Qing Dynasty (1644-1911), when he served as the puppet emperor of the Manchurian regime. It is one of the three great imperial palaces still existing in China.
Because the regime was established by Japan in a bid to pursue colonial domination in northeast China, it was not recognized by the Chinese government. This was why the word "puppet" was used. [China.org.cn/VCG]
