What is the second part of Speak of the devil? Why does everyone know, but no one dares to say?

Sometimes when people are joking, they often say this sentence: Speak of the devil. Everyone can say this sentence. I had no idea that there was a second part of this sentence. But because not many people said it at that time, the first half of the sentence was passed down like this. The second part is a household name, but no one dares to say it. So what is the second part?

Dong Zhuo is too overbearing to bully the son of heaven in the palace. Not only ministers can't stand it, but even governors can't stand it. He didn't leave any face for the son of heaven. Too much. So Wang Yun came up with a honey trap and recognized the story of a female official, Diusim, as his adopted daughter. First Lu Bu, then Dong Zhuo, and finally let them kill each other. Later, Lu Bu killed Dong Zhuo, and the palace was completely in chaos. Dong Zhuo's two right-hand men, Guo Si and Li Jue, fought for power. At that time, the court was in chaos. Guo Si and Li Jue found that Xian Di had escaped, so they sent troops after him. At this critical moment, the first minister of Emperor Xian of Han Dynasty recommended Cao Cao's escort. However, before the emissary set out, Xiahou Chun listened to Cao Cao's orders to protect Emperor Han Xian. After that, the phrase "Speak of the devil and he will come" was widely circulated!

When I hit Puyang, I met the most difficult opponent, and Lu Bu happened to be here. To say that Lu Bu is also a character, he defeated Cao Cao and returned to his hometown, but he couldn't be upright. Lu Bu also found him stealing at night, but let Cao Cao suffer a dark loss and get lost in despair. In this way, Cao Cao was still unwilling, thinking of finding another chance to defeat Lu Bu. Lyu3 bu4 worried that he had no chance to vent. How could he easily miss this opportunity? He immediately sent troops to pursue Cao Cao, and even went into battle to pursue him himself. I accidentally lost him on the way, so I caught a man and asked, "Where's Cao Cao?" The man pointed out the direction at random, and Lu Bu ran after him. As a result, Lu Bu missed Cao Cao, so that there was a saying later, "Speak of the devil and miss him face to face. It's really funny."

In Cao Cao's view, the second half of this sentence is actually self-deprecating. Cao Cao still loves face very much. In order to better save his life, no one dared to say at that time. So the first half of the sentence was widely circulated, and no one dared to say the second half.

I hope the above answers can help everyone. If you are satisfied, please accept them. Thank you.
