Its capital was Gaoping (高平, modern Guyuan, Ningxia).
[1] In late Western Han period, the commandery administered 21 counties: Gaoping (高平), Fulei (復累), Anbi (安俾), Fuyi (撫夷), Chaona (朝那), Jingyang (涇陽), Linjing (臨涇), Lu (鹵), Wushi (烏氏), Yinmi (陰密), Anding (安定), Candu (參讀), Sanshui (三水), Yinpan (陰槃), Anwu (安武), Zuli (祖厲), Yuande (爰得), Xuanjuan (眴卷), Pengyang (彭陽), Chunyin (鶉陰) and Yuezhidao (月支道).
[2] The Eastern Han census in 140 AD, however, documented a population of only 29,060 (6,094 households), and the number of counties had reduced to 8.
[3] Due to attacks by the Qiang people, the commandery's administration was relocated to Youfufeng from 111 to 129.
[4] In 280 AD, the commandery had 7 counties, with a total population of 5,500 households.
