After the fall of the Qin Dynasty, Liu Bang and Xiang Yu fought a big fight for the world, and finally ended in Liu Bang's victory, and Xiang Yu killed himself by the river.
At that time, Liu Bang led the army into the customs, completed the agreement set by King Huai, and the great cause of unifying the world was half completed, and now there was only Xiang Yu, a difficult bone to gnaw.
Xiang Yu also knew that Liu Bang was his greatest enemy, so Fan Zeng, a strategist under his account, wanted to find an opportunity to kill Liu Bang - set up a feast at the Hongmen Gate
However, the news was known by Xiang Yu's uncle, doomed to success, Xiang Bo is a person of great affection, he learned that Xiang Yu had the intention of killing Liu Bang, and quickly ran to Liu Bang's military camp and told his benefactor Zhang Liang.
Zhang Liang dared to be sloppy and told Liu Bang overnight. However, at that time, Liu Bang still had no way to confront Xiang Yu head-on, so he asked Zhang Liang what he should do. Zhang Liang said that the soldiers would come to block, the water would come to cover the ground, and the person who relied on it was Xiang Bo.
On the day of the agreement, Liu Bang took Zhang Liang and Fan Duo to the banquet, and during the banquet, Xiang Yu pretended to summon Xiangzhuang to dance the sword to help him, waiting for the opportunity to kill Liu Bang. Xiang Bo saw Xiang Zhuang's intentions and used his body to cover Liu Bang, and later under the cover of Zhang Liang and Fan Duo, Liu Bang was able to escape from the Chu camp and return to his barracks.
Later, after Xiang Yu's death, Liu Bang gained the world, but he did not embarrass the xiang family, and gave Liu the surname, and Xiang Bo was given the title of Marquis of Sheyang, and died in his later years.
