From Qin to early Han dynasty, parts of Langya were separated to form three new commanderies, Jiaodong, Chengyang and Jiaoxi.
[4] In 41 AD, the territory was converted to a kingdom/principality and granted to Liu Jing (劉京), son of the Emperor Guangwu.
[5] In 140, Langya administered 13 counties, namely Kaiyang (開陽), Dongwu (東武), Langya (琅邪), Dongguan (東莞), Xihai (西海), Zhu (諸), Ju (莒), Dong'an (東安), Yangdu (陽都), Linyi (臨沂), Jiqiu (即丘), Zeng (繒), and Gumu (姑幕).
[6] In 198, four counties (Ju, Gumu, Zhu, Dongwu) were transferred to the reestablished Chengyang Commandery.
In 742, the commandery's territory covered 5 counties: Linyi, Fei, Cheng (丞), Yishui (沂水) and Xintai (新泰).
