Pu Songling in Qing Dynasty was a master of allegory, who wrote that ghosts and gods were superior, greedy and cruel. Because of his lack of talent, he taught private schools in the countryside to make a living.

At that time, in Zichuan County, Shandong Province, the hometown of Pu Laohan's son, there was an official named Wang. His family has a large group of lackeys, including a one-eyed housekeeper named Jin Biao, who is embarrassed and often bares his teeth at the poor.

This guy is evil, but he prefers dancing and writing to show elegance. It is said that Pu Songling's poems are outstanding, so he invited someone to his house and asked for a gift of "four musts".

Pu Songling, whose love and hate are distinct, wrote four sentences with a smile:

A pointed head and a flat head with only one eye.

One-eyed only gets clothes, at the disposal of his master.

This limerick cursing Jin Biao is another mystery. Can you guess what it is?

Answer: "needle".
