Cao Ren in the Book
Still in the romance of the Three Kingdoms, this task is really unlucky, it is simply a 250. For example, when he joined Jin Suozhen eight times in a row, he was caught, and then he failed. For example, when going to attack Zhuge Liang, Zhuge Liang attacked with fire, and he failed again. For example, after Chibi, I confronted Zhou Yu and won this time, but it was Cao Cao who won.
What this literary image describes to us is a cunning man, stupid and cunning anyway.
A real Coss.
So in fact, Coss in history is famous and can only be regarded as a model in the camp of Cao Wei.
Why do you say that? For example, Xelloss once wrote a letter to educate Cao Zhang. He said that a general should follow Cao Ren's example, which is quite high.
And his military achievements. When attacking Xuzhou, he led the army to attack other counties. After the battle of Guandu, he led the army to recover lost ground and defeated Liu Bei. Facing Guan Yu's attack, he never surrendered.
Fiction and reality
In fact, we should not dwell too much on this issue, because The Romance of the Three Kingdoms is only a novel after all, but it has had a great influence on our audience through this long-term spread, so we naturally regard it as a real official history.
Then if you have a correct view of history, you won't believe these things. So it is not important to say that this deviation is not a deviation. It is important to see your understanding of history and this interest.
If we have a correct view of history, treat history correctly and don't completely believe what the book says, then this problem will not exist.
