The story of Battle of Red Cliffs is 50 words.

Main content: In 208 AD, Cao Cao led a great army to attack Wu, and Wu and Shu jointly fought against Cao Cao. Because Wei Jun was not good at water warfare, Kong Ming and Zhou Yu decided to attack by fire. For a pretence, Pang Tong defected to Cao Cao and suggested that Wei Jun ships be tied together with chains to resist the wind and waves; Zhou Yu pretended to be Huang Gai, and Huang Gai pretended to fall to Wei; Kong Ming speculated that the east wind was coming. Huang Gai took dozens of boats to Wei, all of which were firewood.

Wei Jun arrived, Huang Gai lit firewood, and the fire reached Wei Jun by wind. Wei Jun's unfamiliar water boats were connected again, causing numerous casualties. Wei Jun escaped.

Battle of Red Cliffs, extended information, refers to the battle in which Sun Quan and Liu Bei defeated Cao Cao's army in Chibi of the Yangtze River (now northwest of chibi city, Hubei Province) in the 13th year of Jian 'an (2008). This is one of the most famous battles in China's history, and it is the most famous one among the "three major battles" in the Three Kingdoms period.

It is also the first large-scale battle in the Yangtze River basin in China history, which indicates that China's military and political center is no longer limited to the Yellow River basin. Finally, Sun and Liu joined forces to attack with fire, and Cao Cao returned to the north. Sun and Liu each took a part of Jingzhou, which laid the foundation for the tripartite confrontation among the three countries.

Battle of Red Cliffs's failure made Cao Cao lose the possibility of unifying the whole country in a short time, while Sun and Liu started the development of their respective forces through Battle of Red Cliffs's victory. After Liu Bei borrowed Jingzhou from Sun Quan, his strength grew rapidly and he made a profit. Sun Quan led the army to attack Hefei many times, which was unfavorable in several wars.

After returning to the north, Cao Cao spent five years recuperating and pacifying Guanzhong before conquering Sun Quan on a large scale. This battle formed the embryonic form of the third part of the world.
