First, Liu Bang's contemporaries led the troops to fight but couldn't beat Xiang Yu and Mao Dun, Han Xin was still a subordinate, and Liu Bei's contemporaries were repeatedly defeated and defeated, and there was a gap in ability. Second, Liu Bang's ability to employ people can be said to be the best among the founding monarchs in history, and there is a big gap in Liu Bei's ability to employ people. The third is that Liu Bang has a stable ruling team, and Liu Bei only had it in the later period. Fourth, Liu Bang was not reckless, Yongya rebelled and surrendered to the marquis, and did not affect the great cause because of personal grievances, Liu Bei avenged his brother, and finally lost the foundation of Ji Han and lost the capital that was not much. Fifth, Liu Bang can bridge his own internal contradictions, and Liu Bei is to subdue the local forces in Shuzhong and emerge immediately. Sixth, Liu Bang did not rely on his ancestors, Liu Bei went around preaching the descendants of King Zhongshan Jing, the son of Emperor Xiaojing, and at the end of the Eastern Han Dynasty, affected by the two disasters of the party and the rebellion of the ten permanent servants, it was difficult for the Han family to get the support of the scholars. Seventh, Liu Bang fought the world, and his name was justified, Xiang Yu killed the righteous emperor, and Xiang Yu was justified in avenging the Lord, and Liu Bei fought the world only with the descendants of the Han family and the so-called edict of the cloth belt It is difficult to get the support of the scholars. Eighth, the personal qualities of the two are very different, when Liu Bang first got into trouble, his ability was average, but he was able to gradually learn lessons from the war and continue to learn Xi, Liu Bei only learned the skin, and did not learn Xi further, and made mistakes again and again for many years.
