In June, Xiang Yu had defeated and expelled Peng Yue. When he heard that the Han troops had captured Chenggao again, he led his troops to attack the city of Xingyang fiercely from the west, and captured the leading general Zhou Ke alive. Xiang Yu said to Zhou Ke: Surrender to me, and I will confer the general's rank of Shang Jiangjun on you, and reward you with 30,000 households.
