     Two thieves came to a house to steal something, they dug a hole in the wall of the house.

     There lived many mice in the house. The woman in the moonlight saw a mouse crawl (爬行) into the

house. "Look! In comes one," she said to the man in the house. He was so frightened that he hurriedly

crawled out of the house and said to the one waiting outside, "She found me when I was just in." But the

thief outside didn't believe him, so he said, "Let us two try to crawl into the house together." At that time

two mice happened to crawl into the house, too. The woman saw the mice and shouted, "In come two,

catch them!" The two thieves were terribly frightened. The man in the house said, "You saw them come

in but where are they? I will catch them tonight." The two thieves started running away at once.

men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the

time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up.
