Appointed by Han Xin, the commander of the cavalry unit, Guan Ying, led the troops deep into the hinterland of the Chu army alone.

Baby, a native of Suiyang (Shangqiu, Henan), was originally a hawker selling silk fabrics. When Liu Bangxi attacked Yongqiu, Guan Ying joined the rebel army, fought bravely, and made many achievements. When Liu Bang formed the cavalry unit, he promoted Guan Ying to be a middle doctor (commander).

After the establishment of the Han Dynasty, the infant was sealed and waited for. Among the characters in the early Han Dynasty, the infant irrigation was inconspicuous, but the official luck was surprisingly good, and he finally became the prime minister.

Guan Ying participated in two famous incidents, one was to lead the cavalry to pursue Xiang Yu, forcing Wujiang, the overlord of Chu, to kill himself; The other time was a coup d'état with Chen Ping and Zhou Bo to destroy Zhulu and welcome Liu Heng, the emperor of Han Wen.

Therefore, if you are a historical figure, if you want to show your face more in the history books, it depends on whether you can brush up on the sense of presence in key occasions.

Guan Ying led the cavalry troops to fight several victories in Chudi. Xiang Yu sent Xiang Sheng and Xue Gong to lead troops to recover the lost territory in Huaibei. The two sides met near Xiapi, Guan Ying defeated Xiang Sheng, beheaded Xue Gong, and the Han army captured Xiapi. Xiapi is located in Gupi Town, Suining County, Jiangsu Province today, and is close to Pengcheng (Xuzhou), the capital of Chu. The Han army did not stop, captured Pengcheng, and captured the remaining Western Chu Zhu Xiang Tuo.

This is the second and last time that Pengcheng has fallen into the hands of the Han army. Xiang Yu, the overlord of Western Chu, never returned to his capital.

After receiving the news of the fall of Pengcheng, Xiang Yu was in a dilemma. If you want to fight for a while, you can't win, and the supply of grain and grass can't keep up, and even the old nest is occupied by the Han army if you want to retreat. Xiang Yu once again tasted the consequences of Dingdu Pengcheng. Pengcheng is surrounded by plains on all sides, there is no danger to defend, and it is not suitable to be the capital city in the era of cold weapons.

Xiang Yu could only take the initiative to negotiate with Liu Bang. Liu Bang agreed to negotiate and offered to return his parents and wife. The two sides agreed to take the chasm as the boundary, divide the world in the middle, and return to Chu in the east of the chasm, and return to Han in the west of the chasm.

The chasm is an artificial river dug by King Wei Hui during the Warring States Period, which connects the two major river basins of the Yellow River and the Huai River, and connects many major rivers in the East Henan Plain. After several changes, the chasm has long disappeared today, but it is still a golden waterway at the turn of the Qin and Han dynasties. There is a legend that it is inaccurate to confuse the chasm with the Guangwu stream.

The peace treaty was signed, and Chu Fang sent back Liu Bang's parents and wife. Xiang Yu led the hungry and tired Chu army south and retreated in the direction of Yangxia (Taikang, Henan).

Liu Bang planned to return to Guanzhong, but Zhang Liang and Chen Ping did not approve, and they persuaded Liu Bang to say: "If there are two-thirds of the Han king today." The Chu army is short of food, and the veterans of the division are tired, now is a good opportunity to eliminate them, don't raise tigers! ”

Liu Bang listened to their opinions, unilaterally tore up the armistice agreement, and led the army in pursuit.
