Ying Bu
In late 205 BC, Xiang Yu defeated Liu Bang at the Battle of Pengcheng and Liu was forced to retreat to Yu (). Liu Bang told his followers, "People like you are not worthy to discuss great plans with me." One of Liu Bang's advisors, Sui He (), asked why, and Liu Bang replied, "Who can help me go to Huainan and persuade (Ying Bu) to betray Chu, and keep Xiang Yu occupied in Qi for several months, then I can easily take control of the empire." Sui He volunteered for the mission and brought 20 escorts to Huainan. Three days after reaching his destination, Sui He had yet to see Ying Bu, so he said to Ying Bu's advisor, "The king refuses to see me because Chu is powerful and Han is weak. This is exactly the reason why I'm here. Why don't you allow me to meet him first? If what I've said is true, then that's what he wishes to hear. If what I've said is false, then me and my 20 men are willing to die in Huainan to prove that your king is against Han and loyal to Chu." The advisor relayed Sui He's message to Ying Bu, and Ying agreed to meet Sui He.
