Ji Xin was a general under Liu Bang of Han Gaozu, in 204 BC, The Chu King Xiang Yu led the Chu army to attack Xingyang occupied by Liu Bang, the Chu army besieged Xingyang for a month, because there was not much grain in the city, the Han generals were also very tired, xingyang city could not be defended immediately, which made Liu Bang very anxious.
At this time, Ji Xin found Liu Bang and said that he could protect the King of Han from escaping, and Ji Xin's strategy was to first send a surrender letter to Xiang Yu, saying that Liu Bang, the king of Han, would go out of the East Gate of Xingyang to surrender at night, and Ji Xin himself went out of the East Gate to pretend to be Liu Bang to surrender, so that Liu Bang could escape from the West Gate of Xingyang, and Liu Bang obeyed Ji Xin's plan.
In the evening, Ji Xin rode out of the East Gate with Liu Bang's car and blocked his face with his sleeve, at this time Liu Bang, the King of Han, escaped from the West Gate, and Xiang Yu was furious when he saw Ji Xin, but Xiang Yu saw that Ji Xin was very loyal and wanted to surrender Ji Xin, Ji Xin Ning died and did not surrender, and finally Xiang Yu burned Ji Xin to death. It can be said that without Ji Xin's loyal protector, Liu Bang might not have established the Han Dynasty.
After Liu Bang defeated Xiang Yu and established the Han Dynasty, in order to commemorate the merits of Ji Xin, he gave Ji Xin's hometown the title of An Han. Later dynasties have posthumously honored Ji Xin.
