Why did Cao Cao's counselor's IQ drop in Battle of Red Cliffs?

Battle of Red Cliffs's core link is "fire attack", but if you want to succeed with "fire attack", you must have Dongfeng to help you. According to the position of Cao Jun and Sun Liu's allied forces at that time, Zhou Yu had to rely on the southeast wind to burn Cao Cao.

However, Battle of Red Cliffs occurs in the dead of winter. According to common sense, there is a high probability of northwest wind blowing this season, but it is almost impossible to hang southeast wind. It was with this basic judgment that Cao Caocai was not afraid of Zhou Yu's fire attack, followed the advice and connected all the warships together.

Unfortunately, Cao Cao's luck is really not very good. He never imagined that the southeast wind would really blow in the middle of winter. Some people say that Zhuge Liang can blow the southeast wind because he built an altar. In fact, this statement is unfounded.

Let's talk about why the IQ of Cao Cao's counselors is offline, because they may really have no experience in judging the weather. With geographical advantages, Wu Dong had a deep understanding of the weather at that time, so he could judge that the weather in the next few days was in an abnormal state, and Zhou Yu did make full use of it.

Although Cao Cao had many advisers, they didn't know about the weather, but they just judged according to common sense, so they made mistakes.

In addition, most of Cao Cao's soldiers are northerners and are not familiar with the water and soil in the south. They get seasick and sick when they are on the boat, and they lose their combat effectiveness, and their brains may not turn fast.

In this case, we have encountered this abnormal weather again. Cao Cao has no advantages in weather, geography, people and so on, and Battle of Red Cliffs's failure is inevitable.
