Long ago, a prince(王子)wanted to marry a real princess(公主), so he travelled around the world to find her. But he went back sadly.

    One evening when a big rain came, there was a knock on the door. The old queen opened the door, and found a beautiful girl was standing in front of the gate. Water was running down from her hair and clothes. She said that she was a real princess.

    The old queen asked her to come in. She put a pea(豌豆)on the bed, and then put twenty mattresses(床垫)on it. Then she asked the princess to sleep on this bed．

    The next morning, the queen asked the princess, "Did you spend a good night? "

    "Well," she said. "I didn't close my eyes all night. I felt I was lying on something hard．"

    Now they knew that she was a real princess because she felt the pea through the twenty mattresses. The prince married her, and they lived a happy life together.
