Xiang Liang
In 209 BC, when Chen Sheng and Wu Guang started the Dazexiang Uprising to overthrow the Qin dynasty, Ying Bu joined rebel leader Wu Rui, his father-in-law, and rallied several thousand men. After the uprising was crushed by the Qin general Zhang Han, Ying Bu led his followers north to attack the Qin left and right flanks and defeated the enemy at Qingbo (清波; southwest of present-day Xincai County, Henan), and then moved east. When Ying Bu learnt that Xiang Liang had amassed a large rebel force in Kuaiji (then still centered on present-day Suzhou, not Shaoxing), he led his own followers to join Xiang Liang too.
