Introduction to the Imperial Palace: The Imperial Palace is a courtyard composed of three-plexed houses. At the beginning of the establishment of the Puppet Manchukuo, this was the place where Baoxi, the acting government official of the "ruling government", and Hu Siyai, the secretary-general of the "ruling government", worked. After the implementation of the "imperial system", the former "Minister of the Imperial Palace" Shen Ruilin and the subsequent "Minister of the Imperial Palace" Xiqia worked here.
