呉県
In 208 BC, the Qin empire faced rebellions that sought to restore the states conquered during the wars of unification. In Wu County, the uprising of Xiang Liang – a commoner and son of a Chu general – installed Xiong Xin as "King Huai II" () of Chu. Liu joined Xiang Liang's uprising. After Xiang Liang was killed at the Battle of Dingtao, Huai II sent Xiang Yu – Xiang Liang's nephew – and minister Song Yi to lead an army to reinforce the Zhao state against the attacking Qin.
