A greedy man went to the street to buy shoes, thinking to pick a cheaper one.

Unexpectedly, the shopkeeper said:

"My shoes here are free, you can wear them as you like, but there is one condition, that is, you can't talk for three days."

Great! The greedy ghost thought it was a good deal, so he picked a pair of shoes worth 500 yuan and went home quietly.

His wife asked him how much it cost, but he didn't say a word. She asked again and again, but he still didn't say anything.

His family was anxious and went to ask a doctor. The doctor asked him, but he also gritted his teeth and didn't say anything. The doctor panicked and thought it was a strange disease that could not be cured. His wife was scared.

After three days, the shoemaker came to his house and talked to his wife for a while.

Then he went into the house alone and said to the greedy ghost: "The time is up, you can talk." After that, he left.

The greedy ghost told his wife about this matter, and said to his wife with a beaming face, "Great, just don't talk for three days. I got a pair of shoes for nothing, 500 yuan."

The wife glared at him and said, "What? The shoemaker just said he could cure the mute and took a thousand yuan!"
