Liu was responsible for escorting a group of penal labourers to the construction site of Qin Shi Huang’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 punishment, Liu freed the remaining prisoners, some of whom willingly acknowledged him as their leader and joined him on the run from the law.
