Xiang Yu's hometown is Xia Xiang (now south of Suqian 1km, Jiangsu Province, under the abandoned Yellow River embankment of Xuhuai Highway). At the age of 24, Xiang Yu led 8,000 troops to attack from Wuzhong (referring to the old territory of Wu in the Spring and Autumn Period, namely Shanghai, southern Jiangsu and northeastern Jiaxing, Zhejiang Province). At that time, there were not many geographical restrictions, and everyone around them was called Wuzhong, which means that these people were all around Xiang Yu. The land of Wuzhong is also called the land of Jiangdong. It was the local supporters of Xiang Yu who launched this hegemony war.
