However, the Romance of the Three Kingdoms is not history. In real history, Zhuge Liang probably never met Zhou Yu, or he may have met him. There is no record in the history books that the two are their own masters and there is no other relationship.
In 208 AD, Cao Cao went south to Jingzhou, Liu Biao died, Liu Cong surrendered, and Liu Bangnan fled. Lu Su asked Sun Quan to inquire about Jingzhou. When Lu Su arrived in Jingzhou, Liu Bei was defeated by Cao Cao in Changbanpo and fled to Xiakou (now Jiangxia, Wuhan), so Lu Su met Liu Bei in Xiakou and had a talk with Liu Bei about how to plan for the future, and the two sides established an alliance.
Zhuge Liang took refuge in Liu Bei for only a year. In order to persuade Sun Quan to form an alliance with Liu Bei and realize the alliance with Sun Quan in Longzhong, he and Lu Su went to Chaisang (now Jiujiang, Jiangxi) to meet Sun Quan. So Zhuge Liang talked with Sun Quan, and Zhuge Liang answered questions and agreed to Zhuge Liang's alliance request. However, Zhou Yu was not stationed in Chaisang at this time, but in Poyang.
After Zhuge Liang joined Sun Quan, he immediately rushed to Xiakou to return Liu Bei. At this time, Sun Quan was not sure, and he was worried about whether he could defeat Cao Cao militarily. So Lu Su suggested that Sun Quan ask Zhou Yu to ask him. Later, Zhou Yu came to Chaisang from Poyang and advised Sun Quan not to surrender, but to fight Cao Cao, which finally strengthened Sun Quan's determination to resist Cao Cao.
Later, Sun Quan allocated 30,000 soldiers to Zhou Yu, and Zhou Yu led these 30,000 people to set off from Chaisang and go up the Yangtze River to fight against Cao Cao. Because starting from Chaisang and going up the Yangtze River, you must pass through Xiakou, Liu Bei's defense zone, so Liu Bei will meet Zhou Yu at Xiakou, and after the two sides meet, they will continue to move westward. Then Sun and Liu joined forces in Chibi, then defeated Cao Cao, continued westward to Jiangling (now Jingzhou, Hubei Province) city, and then.
Judging from the strategy of Liu Bei Group, when Zhou Yu was fighting against the Confederate army, Liu Bei only showed his face and led the army south to attack the four counties in Jingnan, because this was Zhuge Liang's suggestion to Liu Bei before the war. At the same time, after Liu Bei captured the four counties in Jingnan, Zhuge Liang was responsible for collecting taxes from the four counties to give up military assets. Zhuge Liang probably didn't take part in Battle of Red Cliffs, but went to Jingnan in advance to make war arrangements. Of course, this is just speculation.
Because there is no record in the history books that Liu Bei and Zhuge Liang participated in Battle of Red Cliffs, it feels like Zhou Yu fought a battle alone, but Liu Bei, Guan Yu and Zhang Fei all participated in the recorded battle of Nanjun, but Zhuge Liang did not. At that time, Zhuge Liang was regarded as Liu Bei's counselor, who was in charge of logistics after making suggestions for Liu Bei, while Guan Yu, Zhang Fei and Liu Bei were in charge of fighting ahead.
Therefore, Zhuge Liang, who is in charge of logistics, has nothing to do with Zhou Yu who fought in the front line. Of course, it has nothing to do with this. They may or may not have seen it, but it is definitely not the battle of wits in the romance of the Three Kingdoms. In addition, Zhou Yu in history is not a stingy person, but a handsome guy who is tolerant, generous, handsome and both civil and military. Zhuge Liang in history is not as ingenious as in The Romance of the Three Kingdoms, but he is one of the greatest figures in the history of the Three Kingdoms.
