The Han Dynasty inherited the thirty-six prefectures of the Qin Dynasty, which governed hundreds of counties. Later, after several adjustments, by the time of Emperor Xiaoping, there were a total of one hundred and three prefectures and one thousand five hundred and eighty-seven counties, towns, roads, and marquisates in the whole country. After Emperor Guangwu restored the dynasty, it was found that there were too many officials and the work was too heavy, so he ordered the merging of some counties and towns, reducing ten prefectures and more than four hundred counties, towns, roads, and marquisates. During the reign of Emperor Ming, one prefecture was added, Emperor Zhang added two prefectures, Emperor He added three more, and Emperor An had some subsidiary states manage some counties and towns separately, also separating some of the previously merged counties. By the time of Emperor Xiaoshun, there were a total of one hundred and five prefectures, one thousand one hundred and eighty counties, towns, roads, and marquisates, with a total of nine hundred sixty-nine thousand eight hundred thirty households and a population of four million nine hundred fifteen thousand two hundred twenty.

In conclusion, since the establishment of the Han Dynasty, administrative divisions have undergone continuous adjustments, alternating between mergers and separations, eventually forming the pattern of the Xiaoshun Emperor period.

Original text from "Book of Han, Volume on Geography": Zan commented: "After the reign of Zhongan, the government was fragmented; the marquis stepped down, leaving the people without a consistent leader. Titles were changed, and the fiefs were separated, causing disputes. There were some reductions and increases, which were mostly consistent with previous reports."
