Chengyang was originally a commandery in the Qi Kingdom of early Han dynasty.
Throughout the Western Han dynasty, a total of 53 marquessates was created on the territories of Chengyang and added to the neighboring commanderies.
[3] In late Western Han, the kingdom covered only 4 counties: Ju, Yangdu (陽都), Dong'an (東安) and Lü (虑).
[4] Zhang's descendants held the kingdom until Wang Mang's usurpation.
After the restoration of Eastern Han, the kingdom was granted to Liu Zhi (劉祉), a relative of the Emperor Guangwu.
