YikungongⅠ
As one of west six palaces in living zone of Forbidden City, Yikungong is the residential place of the concubines of Ming and Qing dynasties. It was established in 1417, and initially called Wanangong and later on it was finally renamed Yikungong. Yikungong experiences lots of times retoration. Originally it was a double-yard building. The favorite concubine Yifei of Emperor Kangxi lived here for a long time (maybe most of readers never know who she was. I suggest watching Kang Xi Incognito Travel Tale, a popular TV play series).
Scary Hearsay
Historically, west six palaces, including Chuxiugong, Yikungong, Yongshougong, Xianfugong, Changchungong and Taijidian were the residences of concubines of Qing dynasty. Empress Dowager Ci Xi lived in the west six palaces for more than half life. Over there, many unexplainable stories happened and many people died there. As we all know, just some parts of Forbidden City are publicly opened, and most is still in closure.
