Water glass joke phrase

Cao Yunjin said that, right? I think so, too. It means that Jing Li is a slow-witted person. Something like this.

Cao Yunjin is studying crosstalk at his home in Degang Guo. They are discussing luggage in the room. At this moment, the door rang. Cao Yunjin answered the phone. Jing Li is there, with a cup in his hand. (Because Jing Li and Degang Guo are upstairs and downstairs)

Cao: Uncle, what are you doing?

Li: Nothing. Where is your master?

Cao: In the house. Master, my uncle wants to see you. (Degang Guo comes out)

Li: Brother Shi, can I have a glass of water?

K: OK. What kind of water do you want?

Li: Any water will do.

Guo: Gold, for your uncle.

Jing Li took the water and left. I came back later.

Li: Brother Shi, please give me another glass of water.

Guo: Gold, you pour it. Why are you so thirsty? Is it enough?

Li: That's enough.

Took the water and left. I came back later.

Li: Brother Shi, you have to pour me a glass of water.

Guo: No, what's the matter with you? Cup after cup, can't you order more at a time? What's going on here?

Li: Well, smoking in bed and lighting a cup, the flames are boiling. Look at your back burning.

Guo: How can I not burn you?

Note: All Degang Guo's words come from Cao Yunjin.

I hope this is the joke you want.
