Many years ago, an old man named Mr. Zhu dug（挖） a hole in the field and put 500 yuan in the hole. Then he wrote something on a piece of paper and left it there. It said, "There isn't 500 yuan here." Mr. Zhu's neighbor Mr. Hu saw the paper and dug the hole again and took the money away. And he also wrote something on the paper and left it beside the hole. It said, "Mr. Hu, your neighbor didn't take away your money."
