How to translate "People have heard of it" in "Castle in the Sky"? What does each word mean?

The dialogue in the castle in the air is as follows:

The fool replied: "I don't want to live in a second-story house, but you can first build the top house for me."

When When people heard this, they laughed strangely and said: "How can one not build the first house and get the best!"

Translated into modern Chinese: This stupid rich man stubbornly said: " I just don’t want the second floor below, you must build the top floor for me!” When the others heard this, they all laughed at him. So the word "has" here is a pronoun, specifically referring to the ridiculous thing of "not wanting the first layer but only the second layer". Shiren means the people of that time, and hearing is very simple, it means hearing.
