Jin dynasty (266–420)
Lodged administrative divisions

The Eastern Jin court established three levels of administrative divisions which served as strongholds for the qiaoren: the qiaozhou (僑州, 'province'), qiaojun (僑郡, 'commandery'), and qiaoxian (僑縣, the lodged county), these lodged administrative divisions were merely nominal without possessing actual domain, or rather, they were local government in exile; what could scarcely be denied was their significance in Jin's legitimacy for the northern territory as somewhat an announcement. Furthermore, it was also an action done to appease the refugees' homesickness, which was evoking their desire to reacquire what had been lost.

During the rule of Emperor Yuan, Emperor Ming, and Emperor Cheng, the lodged administrative divisions were concentrated in the area south of the Huai River and the Lower Yangtze Plain. At first there was the lodged Langya Commandery within lodged Fei County in Jiankang, but when it began is not exactly known. Then the lodged Huaide County was also established in Jiankang, around 320. According to the Book of Song:

晉永嘉大亂，幽、冀、青、並、兗州及徐州之淮北流民，相率過淮，亦有過江在晉陵郡界者……又徙流民之在淮南者于晉陵諸縣，其徙過江南及留在江北者，並立僑郡縣以司牧之。徐、兗二州或治江北，江北又僑立幽、冀、青、並四州……(After Disaster of Yongjia, the refugees from You, Ji, Qing, Bing, Yan and Xu provinces came across the Huai River, some even came across the Yangtze River and stayed in Jinling Commandery... The lodged administrative divisions were established to govern them. The seats of Xu and Yan provinces perhaps were moved to the area north of the Yangtze River, where the lodged You, Ji, Qing, Bing provinces were established.)

The lodged Pei, Qinghe, Xiapi, Dongguang, Pingchang, Jiyin, Puyang, Guangping, Taishan, Jiyang, and Lu commanderies were established when Emperor Ming ruled. The rebellions and invasions occurring in Jianghuai area led to more refugees switching to settle in the south of the Yangtze River, where the lodged Huainan Commandery was established afterwards.

However, carrying these out was more complex than the policy was formulated. Several actual counties were under the jurisdiction of the lodged commanderies.

A few lodged administrative divisions are still retained in China nowadays. For instance, Dangtu County was originally located in the area of Bengbu, however, the lodged Dangtu County was established in where it is now, and the latter replaced the former, inheriting its place name.
