^During the Eastern Han Dynasty, Youzhou, as one of 12 prefectures, contained a dozen subordinate commanderies, including the Guangyang Commandery. In 24 AD, Liu Xiu moved Youzhou's prefectural seat from Ji County (in modern-day Tianjin) to the City of Ji (in modern-day Beijing). In 96 AD, the City of Ji served as the seat of both the Guangyang Commandery and Youzhou. The Wei Kingdom reorganized and decentralized the governance of commanderies under Youzhou. Guangyang Commandery became the State of Yan (燕国), which had four counties: Ji County, Changping, Jundu and Guangyang County, and was governed from the City of Ji. Fanyang Commandery was governed from Zhuo County. Yuyang Commandery was govered from Yuyuang (in modern-day Huairou District of Beijing), Shanggu Commandery was governed from Juyong (in modern-day Yanqing County of Beijing).
