What do you mean by laughing hair and feet? (classical Chinese)

After thinking for a long time, I felt ridiculous and couldn't help laughing.

The Chu people are called old tigers and worms, while the Gusu people are called old mice and worms. Yu Changzhou went to Loudong on business, stayed at the post office, put out the candle and went to bed. Suddenly the dishes rang. When I asked this question, Tong Yan replied, "old bug". Yu Chu's people were surprised and said, "Is there such a beast in the city?" "It's not any other animal, it's a mouse," said the child. Yu Yue said, "What's the name of the mouse?" The children say that the customs of Wu are passed down from mouth to mouth. ? Ha ha! The mouse took the name of the old bug, which surprised Yu and made him want to go. He thought about it and smiled. However, today, many people pretend to be vulgar.
