Zhong Liwei, the general of the Chu army, saw that Han Xin was different from ordinary people, so he promoted Han Xin to Qin Bing and became a Ji doctor for Xiang Yu. Han Xin advised Xiang Yu many times, but Xiang Yu was as blind as a bat, ignorant and scolded Han Xin for not knowing the rules. Han Xin was reprimanded by Xiang Yu many times and left Xiang Yu when he was disheartened. Historically, Han Xinxian followed Xiang Yu, but he was not reused, so Xiang Yu lost the world. Even if Han Xin is reused, Xiang Yu can't get the world, so Xiang Yu has lost the hearts and minds!
With Xiang Yu's character, he won't kill a hero, but he won't give Han an envelope. Xiang Yu is a very confident person. He is not afraid of anyone rebelling. He has the ability to defeat any vassal! Tianqi rebelled against Chu, and Xiang Yu led the troops to kill him. Ying Bu betrayed Chu, and Xiang Yu led the troops to break it! Liu bang once joined forces with the five countries to resist Chu, and Xiang Yu broke it. Xiang Yu's self-confidence made him not kill the hero, because his ability is stronger than all heroes!
Throughout history, emperors who loved to kill heroes were all born in the grass. They feel inferior and insecure. Only by killing heroes can they improve their sense of security and existence. Qin Shihuang, Emperor Guangwu of Han Dynasty, Emperor Wendi of Sui Dynasty, Emperor Taizong, Song Taizu, Kublai Khan and Emperor Kangxi failed to kill the hero. Liu Bang and Zhu Yuanzhang killed the most heroes. Although most of the reasons are very good, the means are still too cruel and the scope is too large.
