     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. The thief 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.

     The two thieves wanted to make it clear whether they had been found or not the night before. The next day

they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing

in their fields. The rein (缰绳) broke and the woman came home for a rope. She saw two 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. The woman showed the

sweet potatoes to the man and said,"How they look like the two of last night." The man said,"I asked you to

fetch a rope, why don't you hurry for it?" The two thieves ran away very quickly without their sweet potatoes.
