Beiyang Government
() Yanqing House as well as several other adjoining buildings were built during the Beiyang Government around 1922. During his time as de facto ruler of the Beiyang Government, Cao Kun used Yanqing House as his workplace while living in nearby Huairen Hall. His wives and concubines lived in several of the adjoining buildings. After Cao Kun was overthrown in 1924, he was imprisoned in Yanqing House for two years.
