Cao Cao was in charge of Wei regime and Liu Bei was in charge of Shu and Han regime. At the end of the Eastern Han Dynasty, there was chaos in the world, and Cao Cao, Liu Bei and Sun Quan competed for the world. Zhuge Liang, as a strategist of Liu Bei in Shu and Han Dynasties, gave Liu Bei great help in military, political and economic aspects.
Xiang Yu and Liu Bang are hostile.
Xiang Yu and Liu Bang were the leaders of the peasant uprising army at the end of Qin Dynasty. They became sworn brothers and overthrew the Qin Dynasty together. Later, in the Chu-Han dispute, Xiang Yu was forced by Liu Bang to the Wujiang River and drew his sword and killed himself. Liu Bang defeated Xiang Yu, unified the whole country, and established the Han Dynasty, known as Emperor Gaozu in history.

Liu Bang and Xiang Yu:
At first, Liu Bang was not as powerful as Chu. Whether fighting Qin or Chu, Xiang Yu almost won every battle, but Liu Bang didn't know how to lead the troops to fight. Only one thing helped him turn defeat into victory. What ultimately defeated Xiang Yu was Liu Bang, who was far-sighted, broad-minded, knew how to employ people, reused counselors, listened carefully to their opinions and selected talents.
It was with his hero that he captured the city step by step and expanded his power. Xiang Yu, on the other hand, is violent and conceited and has a strong personality. Most of his soldiers are aristocrats, and they are mediocre, and they are not as good as Liu Bang in strategy. Liu bang survived the hongmen banquet, laying a curse for the future. Chu and Han originally agreed that the two sides would not invade each other.
Unexpectedly, Liu Bang listened to the opinions of Sean and Chen Ping, the ministers, and launched an attack while he was unprepared. He sent troops to attack Xiang Yu's army and surrounded it. Late at night, Xiang Yu heard that all the troops around him sang the local songs of Chu, and he was terrified. He wondered whether the Han army had approached and why there were so many Chu people in the enemy.
So Xiang Yu lost his fighting spirit and drank and sang with his beloved concubine, bringing tears to everyone's eyes and making them sad. Xiang Yu was unwilling to fight, so he led the remaining hundreds of thousands of soldiers to break through the enemy's encirclement and flee to the south. Until Wujiang River, Xiang Yu had no face to see his fellow villagers, so he committed suicide with a knife, and a generation of Chu tyrants disappeared like this.
