What is the story of "Cao Chong is called an elephant"? How do you call an elephant in Cao Chong?

Cao Chong is the best among many sons of Cao Cao. He was clever since he was a child, but Cao Chong was too clever. Although deeply loved by Cao Cao, he couldn't help stabbing him in the back. He died young and didn't make any achievements. Although Cao Chong died young, the allusion of "Cao Chong is an elephant" has been handed down. Let's take a brief look at the story of "Cao Chong is an elephant".

At the end of the Eastern Han Dynasty, Cao Cao got an elephant, which was enormous. People want to know how much it weighs, but they don't know what to do.

Elephants are so heavy that it is difficult for them to move them to weigh them. A group of people walked around the elephant several times and didn't think of a suitable way. Calling an elephant seems to be a simple matter, but the ancients pondered it for a long time and still couldn't find a way.

But Cao Cao's youngest son is very talented. When he learned that the elephant was thinking hard, everyone laughed. He had a plan in his heart, clapped his hands and began to praise the elephant skillfully.

When he was very young, he first asked for help to drive the elephant to the boat. When the elephant reached the boat, Cao Chong drew a line along the side of the boat that was flush with the water. Next, Cao Chong asked people to get the elephant off the boat, and then put stones into the boat, so the boat sank until the water surface coincided with the line drawn by Cao Chong, and Cao Chong ordered people not to put stones.

When they saw this, they generally understood and applauded Cao Chong's wit. Didn't Cao Chong convert the elephant's weight into the stone's weight by lifting the boat? Elephants are not easy to weigh, but stones are easy to weigh.

Cao Chong is a genius for a child to come up with such a clever idea.
