In 202 BC, the long-lasting Chu-Han dispute ended with the suicide of Xiang Yu, the King of Western Chu, at the Wujiang River. When the news reached the tent of Liu Bang, the King of Han, Liu Bang was not at all surprised by the death of Xiang Yu, the old enemy who had once driven him to desperation. On the contrary, he could not believe the news reported by Fan Kuai. It was not until the soldiers presented Xiang Yu's body, which had been cut into eight pieces, to the tent that Liu Bang finally let go of the grievances that had been pent up in his heart for a long time. The death of Xiang Yu, the old enemy, brought unprecedented loneliness to Liu Bang, the King of Han. Facing Xiang Yu's body, Liu Bang even asked: What was this for? Was it the world? Women? Or the "entry agreement"? Han Xin, who had made outstanding contributions in destroying Western Chu and defeating Xiang Yu, had the same complex psychology as Liu Bang. At this time, in Han Xin's heart, where he would go after the war became an indelible shadow lingering in his heart. After years of fighting east and west, both the country and the people hope to bid farewell to the nightmare of devastation and live a peaceful and prosperous life. With the support of the princes, Liu Bang, under the recommendation of "the country cannot be without a monarch for a day", built an altar and proclaimed himself emperor, changed the country's name to Han Dynasty, established the capital in Xiapi, crowned the queen, established the prince, ascended the throne, and became the first emperor of the Han Dynasty. "When the birds are gone, the good bows are hidden; when the cunning rabbits are dead, the running dogs are cooked." Zhang Liang, who knew the emperor's mind well, resigned from the center of power after Liu Bang proclaimed himself emperor of the Han Dynasty, lived in seclusion in the mountains and forests, and devoted himself to practicing Taoism. Han Xin also planned to retire from the past, but the flash of the King of Han's "magnanimity and love for talents" made Han Xin stay. However, Han Xin didn't know that the person who made the King of Han Liu Bang most worried was himself. Just when Han Xin had illusions, Liu Bang "changed" Han Xin to the King of Chu, and took away Han Xin's military power as a general in the name of eliminating the remaining forces of Xiang Yu. Liu Bang stabilized his regime step by step, and Han Xin returned to his fiefdom with the title of "King of Chu". He stayed at home and drank all day. But despite this, Liu Bang still had a grudge against Han Xin. At this time, the news that Han Xin secretly hid Xiang Yu's favorite general Zhongli Mei gave Liu Bang an excuse to deal with Han Xin. Liu Bang originally planned to take down Han Xin by visiting Chendi and summoning various princes at Yunmeng Lake. Unexpectedly, Zhongli Mei thanked Han Xin with his death after hearing the news, and asked Han Xin to meet Liu Bang with his head. Zhongli Mei's head did not dispel Liu Bang's precautions against Han Xin. On the contrary, it gave Liu Bang the opportunity to demote Han Xin to Huaiyin Hou. From the King of Qi to the King of Chu, from the King of Chu to the Marquis of Huaiyin, Liu Bang was more relieved to prevent Han Xin than to put Han Xin to death directly. When General Chen, who was stationed in the western frontier, led his troops to rebel, Liu Bang asked Han Xin to go to war with him, but Han Xin declined due to illness, and Han Xin brought disaster upon himself. When Liu Bang was conquering Chen?, Lü Zhi killed Han Xin in Weiyang Palace. When Liu Bang quelled the rebellion and returned victoriously, on the way back to Chang'an, Liu Bang suddenly decided to take a detour to Pei County, where he drank and chatted with his fellow villagers, and sang his last song "The wind rises and the clouds fly, I return to my hometown with my power over the world..."
