What’s the story behind words with homophones?

Stories with homophones include:

Story 1: Once upon a time, there was a playboy who was lazy and did not study hard since he was a child. When I grew up, I often made jokes because of typos.

One day his wife said she wanted to eat loquats. He took out a piece of paper from the table and wrote a few words on it. After finishing writing, he called his servant to buy loquats. His wife took the paper, looked at it, and burst into laughter. It turns out that it says "Buy Pipa for five pounds".

Two of the five characters were written incorrectly, and "Loquat" was mistakenly written as "Pipa".

After reading it, his wife wrote a limerick at the back: Loquat is not the pipa, it’s just because of poor literacy back then. If the pipa can bear fruit, all the flutes and drums in the city will be filled with flying flowers. This dandy boy blushed with embarrassment after seeing his wife's poem.

Story 2: "Class Flower" and "Moving Flower". One day after class, the teacher hurriedly walked into the classroom and said, "Here are two people, I want the class beauty."

The students thought it was fun, especially the boys, who were very active. After some twists and turns, they finally selected two beautiful girls. Then the teacher waved: Come on, come with me. The Office of Academic Affairs moves flowers.
