Why were there so many talents in Peixian County at the end of Qin Dynasty?

Liu Bang won the world, and these talents became "talents". In Sima Qian's words, it is "following". History always focuses on recording successful people. For example, Fan Kuai, a brave husband, is abundant in the world, but not very talented. There are three truly decisive talents of Liu Bang: Xiao He, Sean and Han Xin. Liu bang, however, is a genius without learning and skills.
