Is there a two-part allegorical saying: seven senses and six noes?

AARON Li, Jilin

There used to be such a joke:

The rich man's son learned from the teacher, one by one, and learned nothing The rich man asked the teacher with great concern, "How is my child studying?" The teacher thought about it, how to say it? Say you're learning well? That's not the case at all. You said you didn't learn well, didn't you? I'm afraid the rich will get angry. Later, the teacher came up with a foolproof saying: "Your child knows six things from seven things." The rich man was very happy when he heard this. He got six out of seven points, which was very good. As we all know, the teacher means: I don't know anything.

What does "nothing" mean? It's simple. I don't understand metaphors at all. This idiom does not come from this joke, but from another source:

Yin is a famous tyrant in history. He abused his power, which put the country in jeopardy. At that time, many people dared not remonstrate with Zhou Wang, sighing secretly. Zhou Wang's uncle Beagan thinks he is his uncle. If he is persuaded, he will regret it. Therefore, he boldly and fully recommended it, and suggested that Zhou Wang practice kindness and kindness and turn over a new leaf. Unexpectedly, instead of listening, Zhou Wang became angry from embarrassment. He killed Beagan and had a laparotomy to see how long Beagan's heart was.

Confucius heard this and said angrily, "If you master it, you will not die." Confucius meant that Zhou Wang knew nothing about seven things. If one thing works, Beagan won't die.

"I don't know anything" is still widely used in people's lives, such as "I really don't know anything about this problem." "She knows nothing about computer technology."
