Ying Bu
In late 206 BC, Gong Ao, along with Wu Rui and Ying Bu, received a secret order from Xiang Yu to kill Emperor Yi of Chu (the former King Huai II) while the emperor was on his journey to Chen County (郴縣; present-day Chenzhou, Hunan). During the Chu–Han Contention, although Gong Ao was on Xiang Yu's side, he did not participate in the conflict.
