Among the three countries is Wei Shuwu. According to the advantages and disadvantages of three different countries, as well as their inheritance and interest relations, it is the general trend that the three pillars stand in the Spring and Autumn Period and the Warring States Period. The important factor is the influence of the background of science and technology at that time. It mainly analyzes the follow-up situation caused by Battle of Red Cliffs and Battle of Red Cliffs.

There are several points:

1. Cao Cao's thought of Wei's hegemony, Liu Bei's ambition of prospering the Han Dynasty in Shu, and Sun Quan's family business in Wu.

2. Wei is actually the country with the best chance to unify hegemony. Why do you want to fight Sun Quan in Chibi first instead of Xishu? Before Battle of Red Cliffs, Teng invaded the territory, first pacifying Liang, and then attacking Chibi. The State of Wu was powerful. Cao Cao was afraid of being harassed by the State of Wu in the East when he attacked the West Shu. But at this time, the West was relatively stable, so he decided to fight first and take Jingzhou first. Jingzhou is the middle position between Wei, Shu and Wu.

3. After Battle of Red Cliffs, the morale of Cao and Wei was greatly reduced.
