What is the second half of Speak of the devil? Why is it rarely mentioned?

Wouldn't it be funny to miss it yourself? This sentence is seldom mentioned because it is ironic.

The original words of this sentence are "Speak of the devil and he will come. It's not fun to miss it yourself. "This sentence is about Cao Cao who ate Lu Bu's defeat and then fled.

However, Lu Bu chased after him. Finally, after Cao Cao put on his makeup, he made a gesture in front, and Lu Bu rode behind. Surprisingly, he didn't recognize it as Cao Cao.

Therefore, in history, because Lu Bu did not see through Cao Cao's tricks, Lu Bu paid an irreparable price in the future: he was killed by Cao Cao when he got off pi.

This: it's funny to miss face to face. More ironically, sometimes a person's success is also due to accidental factors.

For example, in the battle of Feishui in history, Qin was not a failure without the talent and tactics of generals. It was only an accidental factor that led to the retreat and eventually led to the death of Chi. Isn't this ending ridiculous? It's a pity.
