At the end of the Qin Dynasty, under the slogan "The world has suffered from Qin for a long time", the adherents of the six countries rose up in succession. Qin Shihuang's Daqin Empire, which he wanted to pass down from generation to generation, was already in turmoil a few years after his death.

Daqin Empire almost completely lost control of the "new" Qin land, and the six countries that had been destroyed before were re-established. The most powerful one was Xiang Jia of Chu, and his master Xiang Yu was very brave.

In Julu, a miracle was staged and Qin Jun's 400,000 main force was defeated. At this point, I lost the effective strength to clean up the troubled times in the world, so I had to retreat to Qin.

Xiang Yu became famous in World War I and was elected as the anti-Qin leader by the governors of the six countries. Xiang Yu began to embark on the peak of his life, but it was also at this time that Xiang Yu did a very "stupid" thing. He did it, which made people happy, and the governors of various countries cheered in succession, which really solved the headache at that time.

But in the long run, Xiang Yu undoubtedly pushed himself into the abyss of failure. At the end of the Battle of Julu, Qin Jun was not actually wiped out, but more than half of the troops could not bear the unkindness of the King of Qin and surrendered with the Lord.

So at that time, Xiang Yu had prisoners of the same order as his own army, all of whom were human beings who needed to eat. At that time, Xiang Yu even had a headache with the food problem of his own army. Obviously, he could not afford to keep so many prisoners.

But when they were released, Xiang Yu was afraid that after they ran back, they would be rearmed by Qin and continue to fight with themselves. The gain is outweighed by the loss. Plus, the survivors of the six countries took revenge on Qin Jun with great feelings.

Xiang Yu then decided to do one thing at a time, following the example of Qin's famous soldier Bai Qi and killing all the prisoners. This not only solved the problem of food and grass, but also won the hearts of the survivors of the six countries.

But in doing so, Xiang Yu pushed his reputation to the peak at that time, but it also completely offended the people from Guanzhong to Bashu, and Liu Bang, Xiang Yu's later opponent, was obviously much better than him in dealing with such things.

After he entered the Guanzhong area, he signed "Three Chapters of the Contract" with the Guanzhong people, and strictly ordered his soldiers to abide by the military discipline and not to make mistakes that were unfavorable to the Guanzhong people. Later, Chu and Han fought for hegemony, and it was not without reason that Guanzhong people supported Liu Bang.

At that time, Guanzhong was one of the richest areas in the world after hundreds of years of management by Qin State. Coupled with the war at the end of the Qin dynasty, I didn't step on it too much. When Liu Bang entered the customs, most of Qin Jun in the customs chose to surrender directly, so Guanzhong at that time was the best place to preserve productivity at the end of Qin Dynasty.

In addition to fighting bravely, logistics is also indispensable. The miracle of burning one's bridges doesn't happen every day. Xiang Yu lost the hearts and minds of the fertile land in Guanzhong, which is equivalent to losing a large package of logistics, which was picked up by his opponent Liu Bang. This change, Xiang Yu lost.

As for some people, it would be nice if Xiang Yu killed Liu Bang at the "Hongmen Banquet". Obviously, this shows that he did not have a deep understanding of that history. Xiang Yu lost because he lost the "popular support", not because he killed or didn't kill that person. If Liu Bang is killed, Zhang Bang and Li Bang will definitely appear afterwards.
