西汉武帝末年,太常始辖陵县,这标志着“太常郡”的出现,由于太常所辖陵县的数目不断增加,所以“太常郡”的辖地也在增加,而其边界亦随之变化。由于诸陵县呈点块分布,所以“太常郡”的辖地从未有连为一体。从地理分布上来看,诸陵县散布于三辅内,而在行政上却隶属于太常。汉元帝永光年间,废除陵县制度,“太常郡”随之消失。 In the last years of the Western Han Dynasty, Emperor Wu of the Han Dynasty was too often under the jurisdiction of Ling County, which marked the emergence of “too often County”. Due to the ever-increasing number of Lingxian County, the jurisdiction of “too often County” is also increasing , While its borders have also changed. As a result of the distribution of Zhu Ling County block, so “too often county” jurisdiction has never been connected. From the geographical point of view, Zhu Lingxian scattered in the three supplements, but administratively but under the common. Hanyuan Emperor Yongguang years, the abolition of Lingxian system, “too often County ” disappear.
