County Magistrate of Shuhan

Have you read the author yourself? You probably don't have an outline, right?

Emperor Guangwu of the Han Dynasty greatly improved the status of that aristocratic family, not to mention that each aristocratic family had its own private soldiers who would have to shed blood if they wanted to annihilate them. After Emperor Ling of the Han Dynasty resisted the Yellow Turban Army and was unable to suppress it, the court authorized each county to recruit soldiers on its own, which led to the merging of the princes in the later period.
