Xiang Bo was a noble of the Chu state of the Seven Warring States, and an uncle of Xiang Yu. His given name was Chan (纏) while his was Bo (伯). Xiang Bo is best known for preventing another nephew of his, Xiang Zhuang, from assassinating Liu Bang (later Emperor Gaozu of Han) at the Feast at Hong Gate. During the Chu–Han Contention (a power struggle between Xiang Yu and Liu Bang), Xiang Bo attempted to reconcile between the two warring factions. After Xiang Yu's eventual defeat and death in 202 BC, Xiang Bo and his family were pardoned by Gaozu and became nobles of the Han Dynasty.
