Joke: Zhang San has a riddle.

Zhang San: Old four, let me tell you a riddle. I think so. I have good cigarettes here.

Yo! Where is China? Say, what riddle?

Zhang San coughed twice: Listen carefully-it's strange to say anything. It's a human relationship between men. Fly away, butt and head together.

Lisi: Hey hey! Cigarettes, cigarettes. The filter left after smoking can be called cigarette butts or cigarette butts. Right?

Zhang San: Haha, good for you. There is another one who says that everything in the world has magical power and he will pay for all the punishments. Immortals love him, and laymen love him like immortals. Guess the guest on this riddle, but if you can't guess, he will punish you. Old four, what is this?

Li Si: Ha ha ha, wine, good wine. Right?

Zhang San: Haha, you are the middleman!
