As we all know, there is a Chu River Han boundary between the two sides of the chess game, also known as the chasm, located on the Guangwu Mountain on the south bank of the Yellow River in present-day Xingyang City, Henan Province. Here, Chu Xiangyu and Han Liu Bang had made an alliance of chasm, so what happened? What about the final outcome?
Han Gao Zu Liu Bang
On that day, Xiang Yu was divided into princes of the world, but soon after they betrayed each other, Liu Bang was also dissatisfied with Xiang Yu's treachery and sealing himself in Shuzhong, and after harvesting the military genius Han Xin, his strength grew rapidly, and Ming Xiu Dao secretly chen cang, defeated the Yong King Zhang Handan and re-entered guanzhong, and fought many victorious battles all the way to the east. Xiang Yu ran east and west, taking care of himself, and Liu Bang seized Xiang Yu's opportunity to conquer the State of Qi and captured Pengcheng, the capital of the State of Chu. However, Xiang Yu quickly returned to Pengcheng and broke out the famous Battle of Pengcheng, defeating the Han army of 560,000 people in 30,000 people, the Han army suffered heavy casualties, Suishui did not flow, and Liu Bang's father and wife were also captured.

After the Battle of Pengcheng, Xiang Yu regained the upper hand, and after Liu Bang reorganized the soldiers and horses sent by Xiao He from Guanzhong, together with Han Xin's army, Chu Han launched a tug-of-war around Xingyang for more than 2 years. But at this time, Han Xin was not idle, leading the army to conquest everywhere, especially to capture the State of Qi, to help Liu Bang earn a large share of the family business, Xiang Yu gradually declined, and he knew that he had lost his way and was helpless, plus Han Xin began to point the spearhead at the State of Chu, so he wanted to make peace with Liu Bang and agreed to divide the world between the two. Liu Bang agreed to Xiang Yu's request, and the two sides were bounded by a chasm, which was about 800 meters wide and 200 meters deep, with Han in the west and Chu in the east. Of course, Liu Bang did not agree in vain, and Xiang Yu soon released Liu Bang's father and Lü Hou. This is the alliance of the chasm, which forms the division between the "Chu River and Han Boundary" on the chessboard.
Chu-Han Divide
Originally, Liu Bang and Xiang Yu both thought that there was nothing wrong in the world, one of them was kind by nature, one was simple and rude, and they also realized their respective dreams, they should wash and sleep, Liu Bang continued to enjoy his beauty and wine, and Xiang Yu and Yu Ji eventually became dependents. However, the development of the general trend of the world to a certain stage is unpopular, and when they are only one step away from dominating the world, how can the people around them let go of this opportunity to make a name for themselves and become kings? After Qin Shi Huang unified China, no matter how the world was divided, all Chinese had an ultimate goal of unifying China.
Therefore, Zhang Liang and Chen Pingren prevented Liu Bang from returning to Guanzhong, urged Liu Bang to break the treaty, and took advantage of Xiang Yu's exhaustion to take his life. Moreover, he persuaded Liu Bang to believe that once the people lived and worked in peace and contentment, and the blood of the Marquis of Jiangong had cooled, it would be difficult to launch a large-scale war, and if Xiang Yu was spared at this time, it would be equivalent to letting the tiger return to the mountain. Liu Bang eventually obeyed the plan of Zhang Liang and others, and spent a year killing Xiang Yu in the siege of Xiaxia.
