It's 201 A. D. There are no elephants in China, but the king gets an elephant as a present. People are very happy to see this big animal. Everyone carefully watches it and has a question: How heavy is it? But they don't know how to weigh（称重）it. No scales in China are big enough to weigh such a big animal.
The king has a six-year-old son called Cao Chong. He says, “Father, I know the way to weigh it.” No one believes the boy. But after he tells people his idea, they all think it is a good one.
“Here's what you do,” says the boy. “Let the elephant stand in a big boat on the water. Draw a line on the side of the boat at the water level（水位）. Then bring it to the bank（河岸）and let the elephant off. Bring a lot of big stones, put the stones on the boat until the boat goes down to the same water level. Then take the stones out of the boat and weigh all the stones. Now you know how much the elephant weighs.”
“Wonderful! Wonderful!” shout the people. Soon everyone in the country knows that the king has a clever son.
