At the end of the Eastern Han Dynasty, the world was in chaos and the heroes were fighting. Wei, Shu and Wu rose up one after another and formed a tripartite situation, performing a long historical drama of division and unification. The end of the war among the princes formed three powerful forces: Cao Cao in the north "held the emperor hostage to command the princes", successively annihilated Yuan Shao, Yuan Shu and other forces, unified the Yellow River Basin, and occupied the Central Plains; Liu Bei visited Zhuge Liang three times and got his assistance, and was followed by fierce generals such as Guan Yu and Zhang Fei. Finally, after the "Battle of Chibi", Cao Cao was forced to return to the north, and was able to occupy Yizhou and Jingzhou and other places, and gradually developed and grew; Jiangdong Sun family, starting from Sun Jian, has established a firm foothold with the six counties and 81 counties of Jiangdong as its base, and until Sun Quan, its strength has been increasing. After that, the Three Kingdoms fought layer by layer. First, Sun Quan took advantage of the battle between Guan Yu and Cao's troops to send troops to attack Jingzhou. Guan Yu was defeated and fled to Maicheng, and died at the hands of Sun Quan. Afterwards, Sun Quan established the Wu Kingdom. Liu Bei also succeeded the Han Dynasty and established Shu Han. In order to avenge Guan Yu's murder, Liu Bei personally led an expedition to Jiangdong, but his army was alone and defeated. Liu Bei died of illness in Baidi City and entrusted his son to Zhuge Liang. Soon, Cao Cao died of illness, and his son Cao Pi abolished the Han Dynasty and established himself as the king of Wei. After Liu Bei's death, Zhuge Liang assisted the young master Liu Chan and supported the crisis alone. During this period, Zhuge Liang insisted on joining forces with Wu to fight Cao, and after capturing Meng Huo seven times, he stabilized the rear. He also went to Qishan to attack Wei six times, but all ended in failure. Zhuge Liang also died of illness due to overwork in the army. After his death, Jiang Wei succeeded him and attacked the Central Plains nine times, but also returned without success. The last lord Liu Chan was incompetent, the government was corrupt, and the national strength of Shu Han gradually weakened. The Three Kingdoms era ended with the death of Liu Chan and the surrender of Sun Hao. Since then, the Three Kingdoms belonged to Jin.
