In late Western Han dynasty, its territory included 17 counties and marquessates, namely Ye (掖), Chui (腄), Pingdu (平度), Huang (黃), Linqu (臨朐), Qucheng (曲成), Muping (牟平), Dongmu (東牟), Zang (脏), Yuli (育犁), Changyang (昌陽), Buye (不夜), Dangli (當利), Luxiang (盧鄉), Yangle (陽樂), Yangshi (陽石), and Xuxiang (徐鄉).
[1] In 140 AD during Eastern Han, the number of counties and marquessates was 13, including Huang, Muping, Jian (惤), Qucheng, Ye, Dangli, Dongmu, Changyang, Luxiang, Gelu (葛盧), Changguang (長廣), Qianzou (黔陬), and Buqi (不其), the last three of which were formerly part of Langya Commandery.
During the Jian'an Era of early 3rd century, Qianzou was transferred to the newly established Chengyang Commandery.
[4] In Sui and Tang dynasties, Donglai Commandery became the alternative name of Lai Prefecture.
In 742, the commandery's reduced territory covered 4 counties: Ye, Changyang, Jimo and Jiaoshui (膠水, formerly Changguang).
