What's the funny joke about teaching chefs to cook?

Xiao Liang is very clever at a young age.

One day, my uncle asked him: Xiao Liang, you are very clever, but do you have any plans to invite me out now?

Xiao Liang thought about it and said to his uncle, I don't have this ability. But if you are outside, I can invite you in.

My uncle didn't believe me, so he quickly went outside and said to Xiao Liang, "Now let's see how you invited me in from outside!" !

Xiao Liang said with a smile, Uncle, I have invited you out of the house!
