(Burning Red Cliff) Read the part of "Fire Attack" and think about what steps are there in "Fire Attack"? Talk about the reasons for Cao Cao's defeat (burning Chibi)

1. Zhou Yu, Huang Gai, used a bitter plan to cheat and surrender. 2. Pang Tong offered a series of tricks and then attacked Cao Cao's defeat by fire. The reason is that Sun Liu joined forces, Cao Cao's army came from the north, and Marten Han Sui was at work in the rear. There are many soldiers of Cao Cao, but many of them are the original Jingzhou soldiers. The most important thing is that they can't fight water. This is the reason.
