(Reporter Yang Chuanzhi, Correspondent Wang Yanjie) "The elephant is tall and big, with a body like a wall and legs like four pillars", it is really a giant! In ancient times, people could only use one scale to weigh it, so how heavy is an elephant? How can we weigh the elephant?

　 (Reporter Yang Chuanzhi Correspondent Wang Yanjie) "The elephant is tall and big, with a body like a wall and legs like four pillars", it is really a giant! In ancient times, people could only use one scale to weigh it, so how heavy is an elephant? How can we weigh the elephant? At that time, everyone racked their brains and couldn't think of any good idea, but Cao Cao's son Cao Chong had a clue of inspiration to come up with a clever trick. So, how did Cao Chong weigh the weight of an elephant step by step? Let’s take a look at the comic strips of “Cao Chong and others”.

Step 1: Catch the elephant on board the ship

First drive the elephant to a large ship to see how much the hull sinks.

Step 2 Make a mark on the boat

Just follow the water surface and draw a line on the strings of the boat.

Step 3: Load the stone

Then drive the elephant ashore, load the stone on the boat, and load it until the boat sinks to the point where the line is lined.

Step 4: Touch the stone

Then, weigh the stone on the ship. The more heavy the stone, the more heavy the elephant is.

　　The students drew awesomely, and every step was clear and clear.

Cao Chong was only 7 years old at that time, and he was about the same age as his classmates. Because Cao Chong is smart, good at observing, he likes to think about problems, so he came up with a good way to call an elephant. As long as students are like Cao Chong, they observe more, think more, and use their brains, they will become smarter and smarter, and finally become "Cao Chong" to solve problems in study and life.
