Pu Yi, the last emperor of the "famous" in history, is well known to people but not because he has the military merits of Qinhuang and Hanwu, nor because he has the political achievements of Kangxi and Qianlong. At the age of three, he began to ascend to the throne until 1912, and in the middle three times he became the emperor and eventually became a citizen. Throughout the history of Chinas emperor system for more than two thousand years, most emperors only took one emperors position in their lifetime, but only the last generation. The emperor Pu Yi did not bother to make three emperors one after another. It can be said that it is the only three emperors in Chinese history. Coming to Changchun, I walked into the Puppet Manchurian Museum and explored the past and present life of the last emperor's tragedy along the trajectory of history.
