Wu Guang
In 209 BCE, Chen Sheng and Wu Guang started the anti-Qin Dazexiang Uprising. The magistrate of Pei County considered joining the rebellion, and – on the advice of Xiao He and Cao Shen – invited Liu's group to the county to support him; the invitation was transmitted by Fan Kuai, Liu's his brother-in-law. However, the magistrate changed his mind and rescinded the offer; he also ordered Xiao and Cao to be killed lest they open the gates for Liu, but they escaped and joined Liu. On Xiao's advice, Liu secured the aid of commoners from the county beide Pei through written appeals delivered by arrows fired across the border. Peasants responded by killing the Pei County magistrate and welcoming Liu's return. Liu became known as the self-styled "Duke of Pei" ().
