Zhang Han, who had been stubbornly resisting, finally committed suicide in defeat, and Liu Bang completely relieved his worries; Contact Peng Yue to disturb the rear of Chu; Send Han Xin to open up the northern battlefield, attack Wei and capture Wei Wang Leopard, break the dynasty, destroy Zhao and kill Chen Yu. Xiang Yu launched a counteroffensive and besieged Xingyang, and the situation was very critical. Liu Bang used Chen Ping's trick to make Xiang Yu suspect Fan Zeng, and he didn't use his tactics to force Fan Zeng to return to his hometown in anger. Liu Bang sent Ji Xin to pretend to be himself to go to the Chu army to surrender and take the opportunity to escape from Xingyang. Xiang Ji stepped up the siege of Xingyang and captured Chenggao.

In order to alleviate the pressure of the Chu army on Xingyang, Liu Bang led the army through Wuguan, Wan, and Ye, trying to lure Xiang Ji south. In order to cooperate with the actions of the Han army, Han Xin also led the army to the north bank of the Yellow River at this time to support Xingyang. Peng Yue is attacking Xiapi.

Soon, Han Xin annihilated the Qi-Chu coalition army in the Battle of Weishui, completed the strategic detour of the flank of Chu, and sent Guan Ying to lead an army straight to Pengcheng. Xiang Ji suffered from the enemy on his back, and the soldiers were exhausted, so he made an alliance with the Han Dynasty, taking the chasm as the boundary, dividing the world in the middle, returning to Chu in the east and Han in the west. Xiang led the troops back to the east.

The Battle of Qixia was the last major battle of the Chu-Han War, in which about 100,000 people of Xiang Yu's Chu army were completely annihilated, and Liu Bang established the Han Dynasty after his victory.

After the peace treaty, Peng Yue conquered more than 20 cities next to Changyi, seized more than 100,000 grains, and used them as military rations for the Han army, and Liu Bang took advantage of Xiang Yu's retreat to lead the Han army to launch a pursuit of Xiang Yu in Yangxia to lead the Chu army, capture the Chu general Zhou General and 5,000 Chu troops, Liu Bang to Guling, ordered Liu Jia to cross the Huai River, capture Shouchun, and send people to rebel against the Chu State Sima Zhou Yin.

After the victory of the Han army in the battle of Chenxia, Xiang Yu was already at an absolute disadvantage. Pengcheng had been captured by Guan Ying, cutting off his retreat and unable to return to his hometown in Jiangdong, Liu Bang had sent Yingbu and Liu Jia to capture Shouchun, and Xiang Yu's great Sima Zhou Yin rebelled in Shu, making it impossible for Xiang Yu to retreat from this route to Jiangdong.

Xiang Yu was forced to retreat to the city.

The Chu army suffered a decisive defeat in the Battle of Qixia, but still had fierce resistance. Liu Bangnai designed the Han soldiers to learn to sing the Jiangdong Chu folk song, it was night, there were Chu songs on all sides, and the Chu army from Xiang Yu and below thought that the Han had exhausted the Chu land, and the morale collapsed. Xiang Yu led 800 horsemen to break through to the south at night, and after crossing the Huaishui, there were only more than 100 horsemen left around him. The Han army did not discover that Xiang Yu had escaped until dawn, and the Han general Guan Ying led 5,000 horsemen to chase and kill. The Chu army got lost for a time and was caught up in Dongcheng. After several conflicts, there were only 26 people left around Xiang Yu, and the chief of Wujiang suggested that he go to Jiangdong, but Xiang Yu consciously raised troops and had 8,000 Jiangdong children to follow, and today he returned alone, without the face to see Jiangdong's fathers and elders, and did not want to cross the river.
