Ying Bu
One of Ying Bu's favourite concubines fell sick and was sent for medical treatment. The physician who attended to her was a neighbour of a palace official called Ben He (). As Ying Bu's concubine often visited the physician, Ben He used the opportunity to get close to her and offered her expensive gifts, and they had drinks at the physician's house. When the concubine returned home she praised Ben He in front of Ying Bu, saying that Ben He was a warm hearted man. Ying Bu asked her how she knew Ben He, and she told him everything. Ying Bu began to suspect that Ben He was having an affair with his concubine. Ben He became afraid when he heard that Ying Bu suspected him so he feigned illness and remained at home. Ying Bu became more angry and wanted to arrest Ben He. In desperation, Ben He accused Ying Bu of plotting a rebellion and fled to the capital Chang'an. Ying Bu sent his men to pursue Ben He but could not catch up with the latter. Upon reaching Chang'an, Ben He claimed that Ying Bu was showing signs of plotting a rebellion and urged the Han imperial court to send an army to launch a preemptive attack on Ying Bu. Emperor Gaozu discussed with his chancellor Xiao He, and the latter commented, "Ying Bu wouldn't do this. I believe that his enemies are trying to frame him. Please put Ben He under custody first and then send people to investigate Ying Bu." When Ying Bu saw that Ben He had escaped and accused him of plotting a rebellion, he suspected that Ben He had already revealed what he had been secretly planning to do. Besides, the Han imperial court had sent people to investigate, so Ying Bu decided to proceed with his plan. He killed Ben He's family and started a rebellion. When news of Ying Bu's revolt reached Chang'an, Emperor Gaozu pardoned Ben He and appointed him as a general.
