1. Xiang Yu enfeoffed the world, which is unfair.
Xiang Yu is a hero and a symbol of an era. Qin Shihuang mentioned his ambition and verve during the military parade. Can he replace it? Don't doubt. So what replaced it? Status and power, so how can a person be willing to share the world with others, and others may not be willing to share the country with themselves. Xiang Yu's intentions can be seen from his small bag.
Although xiang yu packet principle is? Divide the king by merit, but this is obviously not the case in practice. Liu Bang is the best example. Out of selfishness, Xiang Yu divided Liu Bang into three counties, Ba, Shu and Hanzhong, which were located in remote areas. Besides Liu Bang, Xiang Yu also assigned Chu Huaiwang to the remote and wild county of Chen. But in contrast, Xiang Yu is another matter. He put nine counties, such as Liang and Chu, which were the most prosperous and wealthy at that time, under his jurisdiction. In short, it was a dictatorial enfeoffment in 206 BC. How can it be fair?
2. The princes rose up and rebelled.
Xiang Yu distributed the rich land to himself and his relatives, and scattered other threats to his existence to remote places. How can princes not oppose this naked ambition? The first to bear the brunt was not Liu Bang, but Tian Rong, an anti-Qin veteran. Later, Liu Bangcai followed suit and formally rebelled. The result of this warlord's opposition may have been expected by Xiang Yu, but it was only a step away after all. Although Liu Bang's fiefs were remote, Bashu and Hanzhong were the most developed agricultural areas and important granaries. And Xiang Yu didn't expect the warlord's rebellion to be so menacing that it eventually swallowed everything up.
