The story of Cao Cao and Sun Quan, 50 words.

In the 13th year of Jian 'an (208), in the same year, Cao Cao, the prime minister of the Eastern Han Dynasty, fell in Yicheng, while General Zuo and Liu Bei were in Yuzhou. After Cao Cao occupied Jiangling (Nanjun Zhisuo), he wrote to Sun Quan to win Dongwu. Soochow is divided into two factions: the main war faction, headed by Lu Su and Zhou Yu, and the main peace faction, headed by Zhang Zhao. Zhang Zhao was very convincing at that time, but Sun Quan intended to fight Cao Cao. At this time, Lu Su brought Zhuge Liang, Liu Bei's counselor, from Jiangxia, indicating Liu Bei's determination to unite with Sun Cao. Zhou Yu's timely return shows all kinds of disadvantages of Cao Cao, and the war is expected to win. Sun Quan made a decisive decision and decided to take Zhou Yu and Cheng Pu as the commanders of the left and right wings to join hands with Liu Bei against Cao Cao. Zhou Yu defeated Cao Cao with a crowd of 50,000 in Chibi with Huang Gaimou. This is the famous Battle of Red Cliffs in history. After this war, Liu Bei and Zhou Yu pursued to Nanjun again, and Cao Cao had to withdraw to the north, leaving Coss and Huang Xu in Jiangling and sending Le Jin to guard Xiangyang.
