Many years ago, while on a visit to America, a wealthy Chinese businessman was fascinated by a powerful microscope. Looking through its lens to study crystals and the petals of flowers, he was amazed at their beauty and detail. So he decided to purchase one of these devices and take it back to China. He thoroughly enjoyed using it until one day he examined some rice he was planning to eat for dinner. Much to his dismay, he discovered that tiny living creatures were crawling in it. Since he was especially fond of this staple food in his daily diet, he wondered what to do. Finally he concluded that there was only one way out of his dilemma -- he would destroy the instrument that caused him to discover the distasteful fact! So he smashed the microscope to pieces.
