Pu Tong was a figure in the late Qin and early Han dynasties, who was able to speak eloquently and was a strategist under Han Xin. In the fourth year of Han (203 BC), Han Gaozu's ancestor Liu Bang sent Li Shiqi to persuade him to surrender the State of Qi, the King of Qi had promised to surrender to Liu Bang, at this time Han Xin was trying to attack the State of Qi after pacifying the three kingdoms of Zhao, Dai, and Yan, Han Xin heard that Li Shiqi had persuaded the State of Qi to surrender, and wanted to stop the march, at this time, Pu Tong persuaded Han Xin to continue to attack the State of Qi, and when the King of Qi saw that Han Xin's army was approaching the city, he thought that Li Shiqi was helping Han Xin to deceive him, so he cooked Li Shiqi to death, and the King of Qi himself fled. Han Xin pacified the State of Qi, first declaring himself acting As King of Qi, and later Liu Bang making Han Xin the official King of Qi.
After Han Xin became the queen of Qi, Qu Tong said to Han Xin again: In this situation, who can win the world is up to you Han Xin to decide, helping Liu Bang can make Liu Bang win, helping Xiang Yu can make Xiang Yu win, it is better to let Chu and Han exist, and they are divided into three worlds, standing on their feet. Han Xin did not follow his advice, Han Xin thought that Liu Bang had a deep affection for him, and would never see Li Forgetfulness and betray Liu Bang, and rejected Ku Tong, who then pretended to be crazy and stupid as a wizard.
Later, Han Xin helped Liu Bang defeat Xiang Yu and establish the Han Dynasty, Han Xin began to be jealous of Liu Bang, first from the King of Qi to the King of Chu, and then because of his crime was demoted to the Marquis of Huaiyin, and later someone accused Han Xin of plotting rebellion and was murdered by Lü Hou Xiao Hehe, Han Xin said when he was dying: I really regret not listening to The Words of Pu Tong, so that I was killed by a woman. Because of this sentence, Pu Tong was implicated by Han Xin.
Liu Bang wanted to summon Qu Tong into the palace to kill him, Liu Bang asked Qu Tong why he had instigated Han Xin to rebel before, and Qu Tong said: At that time, I only knew that there was Han Xin, and I didn't know that there was you, at that time, the people in chaos in the world wanted to fight for the world, but they were not capable enough, could you kill all the people who wanted to fight for the world before? Liu Bang felt that what he said was reasonable, so he pardoned Pu Tong.
