The story of Chinese characters

Once upon a time, there was a dude who was lazy and didn't study hard. When I grow up, I often make jokes because of typos.

One day, his wife said she wanted to eat loquat. He took out a piece of paper from the table and wrote some words on it. After writing, he asked the servant to buy loquat. His wife took the newspaper and read it. She burst out laughing. It turned out that it said "buy five catties of pipa". Five words were wrongly written, and the word "loquat" was wrongly written as "pipa". After watching it, his wife wrote a song in the back.

Loquat is not this kind of pipa,

It's only my poor education.

If the pipa can bear fruit,

The city is full of flutes and drums.

The guy blushed when he read his wife's poem. "Loquat" and "Pipa" have the same pronunciation, and both pronounce pípa, which is homophonic. But "loquat" is a kind of fruit, and "pipa" is a stringed instrument, with completely different meanings and writing methods.
