The "aperture" in "knowing nothing": its original meaning is a hole, which refers to the metaphor of the heart orifice, which means the key to things.

There was once such a joke:

The son of a wealthy family studied with a teacher, but he never learned anything. The rich man was very concerned and asked the teacher: "How is my child studying?" The teacher thought about it over and over again, how to say it? It is not the case at all to say that he is studying well. He said he didn't learn well, but he was afraid that the rich man would be angry. Later, the teacher came up with a perfect explanation: "Your child's seven orifices are open to six." The rich man was very happy when he heard that, all seven orifices were open to six, which was very good. Little did he know that the teacher meant: he knew nothing.

The meaning of "knowing nothing" is very simple, and it is a metaphor for not understanding at all. This idiom does not come from a joke, but from another source:

King Zhou of Yin was a famous tyrant in history. His excessive sexual behavior has put the country in danger. At that time, many people did not dare to advise King Zhou and sighed secretly. King Zhou's uncle Bigan thought that he was his uncle. If he tried to persuade him, he would definitely repent. So he boldly recommended him with all his strength, urging King Zhou to practice good deeds and be benevolent, and to correct his evil ways. Unexpectedly, King Zhou became angry after hearing this. He killed Bigan and performed a dissection to examine Bigan's heart, hoping to see how Bigan's heart grew.

Confucius heard about the incident and said angrily: "If his orifices are clear, he will never die." Confucius meant that King Zhou didn't understand any of his seven orifices. If there was someone who knew everything, Bigan wouldn't have died.

Nowadays, "know nothing" is still widely used by people in life, such as "I really know nothing about this question." "She knows nothing about computer technology."
