Cao Chong said elephants (allusions)

Cao Chong, also known as Cang Shu, was the youngest son of Cao Cao in Wang Wei during the Three Kingdoms period. He was gifted and quick-thinking, and by the time he was five or six years old, his intelligence was equal to that of an adult.

When Cao Chong was about ten years old, Sun Quan, the king of Wu, once sent someone to send an elephant to Cao Cao. Elephants grow in the jungles of the south, which are rarely seen by northerners. So Cao Cao took his son and officials to watch.

Everyone looked at the monster and talked about it. Everyone wants to know its weight, but where can there be such a big scale?

Cao Cao also wanted to know the weight of the elephant, so he asked the civil and military officials and said:

"Can any of you find a way to call it?"

Minister of civil and military affairs, look at me, I look at you, and there is nothing to do. At this time, Cao Chong walked up to Cao Cao and said, "Father, I have an idea. I call it an elephant."

Cao Cao knew that Cao Chong had always been clever and liked him very much, so he said, "What do you think?"

Cao Chong said: "With a big ship, first put the elephant on the big ship, carve a mark on the draft of the big ship, and then take the elephant ashore. Then put some stones on the boat and let it sink to the original marked depth. Just weigh the stone and you can know the weight of the elephant. "

Hearing this, Cao Cao repeatedly praised and said, "Good! This method is good! "

So Cao Cao immediately asked people to prepare boats and stones. Sure enough, he quickly weighed the elephant.

Later, people used the allusion "Cao Chong is an elephant" to praise those young, intelligent and talented people. (Yaya)
