The Hongmen Banquet was a famous event in Chinese history that occurred in 206 BC. At that time, Liu Bang and Xiang Yu were engaged in a fierce war for control of the country. After Xiang Yu's defeat at the Battle of Gaixia, he was forced to retreat to Hongmen. Liu Bang took the opportunity to send his strategist Lü Bu, Liu Jing, and others to lure Xiang Yu to a banquet where he would be trapped.
