Introduction to Changchunxuan: Changchunxuan was built in the early period of the Puppet Manchukuo period. It was first a four-square and five-square boudoir. In July 1937, Puyi's father Zaifeng lived here when he went to Manchukuo to congratulate Puyi on his title of "Emperor". It later became Tan Yuling's main activity place. After Tan Yuling's death, she was laid to rest here.
