A merchant’s merchandise were of high quality. Most countries adopt metric system and so his country did. The merchant sold electrical appliances, such as microcomputer, microphone, microprocessor and microwave ovens. Also, he sold a kind of metal, mercury. One day, when he was using a microscope to watch the microbe, a messenger visited him. The messenger was one of his friends. This time he mentioned his son and began to complain, “My son messed up the house everyday. The whole family was at the mercy of his hands.” The merciful merchant showed mercy to the poor father, “Don’t scold him, he was a mere child. He has his merits. Try a new method, maybe he will listen to your words.” The messenger had better mental outlook. There was a merry smile on his face. He told the merchant, ”The restaurant across the street has fish on menu today. Let’s try it. My treat today.”

　　一个商人的商品质量很好。大多数国家采取米制，他的国家也是这样。商人卖一些电器，比如微型计算机，话筒，微处理器和微波炉。而且他还卖一种金属，水银。一天，他正在用一台显微镜观察微生物的时候，一个送信者来拜访他。送信者是他的一位朋友。这次他提及了他的儿子然后开始抱怨：“我的儿子每天把房子弄乱。全家都在他的支配下。”仁慈的商人对这位可怜的父亲表现出了怜悯：“不要责怪他了。他只不过是个孩子。他有他的优点。试试新的方法，没准他会听你的话。”送信者的精神状态好了一些了。愉快的笑容浮现在他的脸上。他告诉商人：“街对面那家餐厅今天菜单上有鱼。让我们去尝一尝。今天我请客。”
