When was the Puppet Manchuria Period?

The puppet Manchukuo (1932 March1-1945 August 18) was a puppet regime established by Japanese occupation of three northeastern provinces of China. Because the National Government, China and the international community refused to recognize the puppet Manchukuo regime, it was called "puppet Manchukuo" or "puppet Manchukuo". The "capital" is located in Xinjing (now Changchun, Jilin), and the "territory" includes all the three northeastern provinces of China except Kanto Prefecture (now Lushun and Dalian), as well as Chengde City and Qinhuangdao City in Mengdong and Hebei Province.
