Foreigners have been studying Chinese hard for ten years, but they can't understand the meaning of the word "meaning"

This is a joke, but it is enough to prove that China culture is really profound. After studying Chinese hard for ten years, foreigners went to China to take the Chinese exam. The question is as follows: Please explain what each "meaning" in the following sentences means. When A Dai gave the leader a red envelope, the conversation between them was very interesting. Leader: "What do you mean?" A Dai: "It doesn't mean anything, it means something." Leader: "You are not interesting enough." A Dai: "Nothing, nothing." Leader: "You are really interesting." A Dai: "Actually, there is no other meaning." Leader: "Then I am embarrassed." A Dai: "Sorry." Results: The foreigner was at a loss, handed in a blank sheet of paper and returned to China. . .
