Ying Bu
Upon reaching Xiayi (下邑; east of present-day Dangshan County, Anhui), which was guarded by his brother-in-law, Liu Bang reorganised his troops for a retreat. When he arrived at Yu (虞; present-day Yucheng County, Henan), he sent a messenger to meet Ying Bu, the King of Jiujiang, and persuade Ying Bu to support him. Ying Bu agreed to join Liu Bang and rebelled against Xiang Yu. Upon learning about it, Xiang Yu sent Long Ju to attack Ying Bu.
