One day, Cao Cao gets an elephant. He wants to know its weight. But the elephant is so big. Its big body looks like a wall and its ears look like two big fans. Nobody can weigh the elephant.
Cao Cao’s little son, Cao Chong tells Cao Cao he can weigh it. Cao Chong first lets the elephant go onto a boat in the river. He marks the water line on the boat.
Then, Cao Chong lets the elephant come back to the bank. He asks people to put some heavy stones in the boat.
Cao Chong weighs each of the stones. In this way, he weighs the elephant. Cao Cao is very happy. “Your idea is so great! What a clever boy!”
