After the demise of the Qin Dynasty, Xiang Yu and Liu Bang became the two forces most likely to dominate the whole country. Of course, before Chu Han, Xiang Yu was stronger than Liu Bang in force and strength. Therefore, in every major war, Xiang Yu always defeated Liu Bang, but Liu Bang wanted to be an invincible Xiaoqiang. Although he lost every time, he didn't die, and the Vietnam War became stronger.
In 204 AD, Liu Bang sent troops to attack the altitude. Cao Yu, the general guarding the city of Xiang Yu, first stood by the city gate, but did not take a step in front of it. Seeing this, Liu Bang called an army and shouted at the altitude. Cao Yu, who had a bad temper, couldn't stand the insult of the Han army and went out to fight. As a result, Liu Bang's trap defeated him.
Later, when Xiang Yu came to the altitude support, Liu Bang had occupied the altitude, so both sides occupied a top of Guangwu Mountain. Because the distance between the two mountains is less than 200 steps, there is only one mountain stream in the middle, and both sides can hear the propaganda, so it became the famous "Chu Han Hong Gully" in the history of later generations.
The two sides fought dozens of battles here, big and small, and each won or lost. On the other side of the battlefield, Han Xin has occupied Qi and defeated the Dragon Army that came to support Qi. Xiang Yu felt very uneasy about the defeat of the dragon car and wanted to end the battle as soon as possible, so Xiang Yu came up with an idea. The next morning, Xiang Yu shouted to Liu Bang from the wall: "It has been so long since the world war, and the people have been displaced for so long because of us."
Xiang Yu's words were not only heard by Liu Bang, but also by the soldiers and civilians in the city. If Liu Bang refuses, not only will the morale of the Han army be damaged, but even the Liancheng people will be unstable. However, if you promise to fight Xiang Yu one-on-one, you don't have to fight. This is not a level. What can you do? Later, Liu Bang thought about it and came up with a way. He smiled and shouted to Xiang Yu, "I would rather fight for wisdom than strength." This means that a gentleman's words are useless. Xiang Yu was furious after hearing this, and an arrow hit Liu Bang's hand. But Liu Bang was not only angry, but also smiled and covered his toes and said, "Take my finger." Until then, Liu Bang's Han army took the initiative in an all-round way, and Xiang Yu became weaker and weaker until Wujiang committed suicide.
