Yu Dafu, a writer, once watched a movie with his wife. His wife found that he took some money out of the soles of his shoes. His wife was puzzled and asked him why he put the money on the soles of his shoes. He explained that when he started, he was poor and didn't have much money. Now he's a bit famous. He wants to step on money, which has been on his money for many years, and his wife immediately has feelings for him. A writer is a writer, and even the discovery of hiding private money is so specious.
