沛県
Liu was responsible for escorting a group of penal laborers to the construction site of the First Emperor's mausoleum at Mount Li. During the journey, some prisoners escaped; under Qin law, allowing prisoners to escape was punishable by death. Rather than face justice, Liu freed the remaining prisoners and fled. Liu was joined by some of the grateful ex-prisoners, and he became their leader. They took over an abandoned stronghold on Mount Mangdang. Liu secretly remained in contact with some old friends, including Xiao He and Cao Shen in Pei County.
