Who knows the joke of speaking of the devil?

This is a historical saying:

When Li Jue and Guo Si were at war, Emperor Xian of Han once escaped from danger. However, after Li Guo joined forces, he continued to pursue Emperor Xian of Han Dynasty. It was suggested that Cao Cao could be rescued by actively suppressing the Qingzhou Yellow Scarf Army. However, before the messenger came out, the allies had been killed. Seeing that there was no way out, Xia Houdun was ordered by Cao Cao to lead the army to "protect" and achieved success. After that, the founding Coalition was defeated and Cao Cao was sealed. Therefore, there is a saying called "Speak of the devil and he will arrive".

This is a related joke:

A grave robber accidentally entered a huge grave. He finally came to an old coffin. After observation, he found that the tomb belonged to Cao Cao.

The grave robber said, "I really made a fortune this time. This tomb is actually Cao Cao's! "

Who knows that the voice just fell, and he was slapped on the shoulder by a person. He was surprised and asked warily, "Who?" The man behind him replied in a hoarse voice, "Cao Cao!" " "

Damn it, speak of the devil and he will come!
