Once upon a time, a man from a country called Zheng wanted to buy a pair of shoes. But he didn't know what size he wore. So he measured his feet with a stick as a size and then he went to a market in town.
In the market, the shoe keeper took out a pair of new shoes and asked the man to try them on. However, the man found he left the stick at home. So he said, "I'm sorry, I forgot to bring the size here! I'll go home to get it back. "The shoe keeper said"Your feet are with you, you can try on the shoes with them, are your feet not better than the size? " "No, the size is right, I believe it. "answered the man. Then he came out of the market and went back home.
After he got the stick, the man hurried to the market again. But the market was over.
