character from a story

I read many interesting stories when I was a child. Now I want to talk about a character called Caochong, a very intelligent child from Han Dynasty, the son of the famous warlord Cao Cao. He was renowned as a child prodigy (神童), having the intelligence of an adult at the age of five. He is best known for his ingenious （有独创性的）  method of weighing an elephant using the law of buoyancy  （浮力）.  

Once, Caochong’s father received an elephant as a gift. Caocao was very eager to know the weight of the elephant, so he asked his followers about the way to weigh the elephant, but no one could provide a solution. However, his son Cao Chong replied, ‘Put the elephant to the boat and mark on it the load line; then drive the elephant away and put stones in the boat until it reaches to the same load line; finally, weigh the stone, add the weights together, and you will know the weight of the elephant.’ Hearing about this, CaoCao was pleased. He ordered his men to follow the guidance of Cao Chong, and finally figured out the elephant's weight.

This story just gave me a very deep impression. When I faced difficulties in my childhood, I would remember Caochong. Since he could come out solutions for difficulties problems at such a young age, I believed I should try my best, too.
