Han Xin
After his demotion, Han Xin knew that Gaozu was beginning to distrust him and had become wary of his talent. Hence, Han Xin claimed to be ill and stayed at home most of the time to reduce Gaozu's suspicions. Around 197 BC, Chen Xi (Marquis of Yangxia) met Han Xin before leaving for Julu, where Han Xin promptly pulled him aside, dismissing all nearby servants. He promised to aid Chen Xi from inside the capital if Chen Xi were to start an uprising against the Han Dynasty. Not long after, Chen Xi rebelled and Gaozu personally led an army to suppress the rebellion, while Han Xin claimed sickness and stayed behind.
