"Professor Huang, your question is too simple. You can tell the weight after weighing it."

An audience member stood up and replied to Huang Yifan.

"Haha, this classmate, the ancient title is not as developed as modern. The three kingdoms period has recorded the title, with a maximum weight of only 250 kilograms. The adult elephant is usually 4-7 tons, and even larger than ten tons. Although the elephant presented by Sun Quan to Cao Cao did not say how big it is, it must not be small. Not to mention more than ten tons, there must be a few tons. And elephants weighing a few tons cannot be measured by scales."

Only then did everyone in the audience realize this denial.

Yes, that was in ancient times, and during the Three Kingdoms period, when productivity was not very developed.

During the Three Kingdoms period, you wanted to weigh dozens of tons of things at once, which was basically impossible.

Then, someone stood up and replied, saying that he had killed the elephant and then called it piece by piece.

Of course, although this stupid method is feasible, who dares to kill the elephant sent by Sun Quan?

After a while, everyone shook their heads: "Professor Huang, your problem is too difficult."

“It’s indeed a bit difficult.”

Huang Yifan nodded: "At the beginning, I didn't expect any good idea. However, I didn't expect that Cao Chong, who was only 5 years old a thousand years ago, thought of it."

Looking at the scene of everyone in the audience who didn't believe it, Huang Yifan smiled and said, "I know you may not want to believe it, so I will announce the answer."

While saying that Huang Yifan turned on the computer screen. At this time, there was an elephant painted on the screen, and several ancient people were also painted standing in front of the elephant.

"This painting is the scene that was called an elephant at that time. The ministers had no choice. At this time, Cao Chong walked to his father Cao Cao and said, "Father, I have a solution." Cao Cao asked, Cao Chong, none of us adults can do it. What can you, a child, have a solution? Cao Chong then said, we can drive the elephant to the boat and make scratches on the water where the water is missing. Then drive the elephant off the boat and move it to the boat with real objects..."

PPT demonstrates the whole process of Cao Chong calling the elephant, but when everyone in the audience saw this scene, they were shocked again.

"Using buoyancy, Cao Chong perfectly solved the problem of elephant weight. Therefore, to calculate the weight of the elephant, we just need to weigh these physical objects one by one and add them."

Huang Yifan finally announced the answer: "This story is called Cao Chong's Elephant."

Applause appeared again.

"Wonderful."

"sharp."

"I used to think that Professor Huang was too tricky to not talk about Kong Rong. Now I think this Cao Chong is more interesting."

"Yes, yes, Cao Chong, who is only 5 years old, is as smart as an adult. His intelligence is even more powerful than his brother Cao Zhi."

"But, it's not right. Professor Huang, I seem to remember you said in the last class that Cao Cao liked Cao Zhi very much at that time, so why did he like Cao Chong the most? If he liked Cao Chong the most, he should consider making Cao Chong the crown prince. How could he have the idea of ​​making Cao Zhi the crown prince?"

Because they were two brothers, Cao Zhi had just finished the lecture in the last class, and the audience still remembered it freshly. When it came to Cao Chong, some listeners stood up and asked Huang Yifan and said.

“This question is a good question.”

Huang Yifan nodded and said, "This is what I am about to say."

"Cao Chong, a genius, showed amazing wisdom at the age of 5, and was no less than adults, and even more powerful than adults in some aspects. Therefore, Cao Cao liked Cao Chong the most, and he also had the idea of ​​making Cao Chong the crown prince. However, there are unexpected situations in the world, and people have good fortune and good fortune. Cao Chong unfortunately fell seriously ill at the age of 13..."

With a clang, everyone in the audience secretly shouted, and then, when they heard the word "death" and the crowd were completely stunned.

"It's dead!"

"Damn, no."

"God is jealous of talent, it is really jealous of talent."

Many people couldn't believe it.

"Sister."

"What a good genius. I thought he was waiting for him to reach the peak of his life, but I didn't expect that he would die."

"Yes. Cao Zhi was the same last time. He thought Cao Zhi was a powerful figure. Unexpectedly, he was deposed by Cao Cao in the end. However, it cannot be blamed for Cao Cao. Cao Zhi is so literary. He thought it would be great to be favored by talent and betray him. However, Cao Chong did not make any mistakes. However, God actually accepted him."

Many people whispered.

"Sometimes history is like this helplessness, just like our life. Cao Chong's death has a great blow to Cao Cao. After Cao Chong's death, Cao Pi came to comfort Cao Cao. Cao Cao looked at Cao Pi and said sadly, "This is my misfortune, but it is your great blessing." After that, Cao Cao shed tears. He also hired Cao Chong, the dead daughter of Zhen's family, to bury him with him, and posthumously gave him the official seal and ribbon of the cavalry commander, and ordered Cao Cong, the son of Cao Ju, to be the descendant of Cao Chong."

At this point, the second lesson of Baijia Forum has ended.

...

"Kong Rong gave the pear."

"Cao Chong is called an elephant."

Watching Huang Yifan's second episode of TV on the Hundred Schools Forum, Zhou Binglin, professor of the History Department of Yan University, cursed: "It's a mess, what are you talking about."

Zhou Binglin cannot verify whether there is any story about "Kong Rong's Pear" and "Cao Chong's Elephant" in history. He is an expert in the history department, so he naturally knows that you cannot verify such gossip stories at all. If you really want to verify, there will be a lot of non-existent in history, but we have always believed that there is something that exists. This is a contradiction in history. For example, people have always believed that Qu Zi died after jumping into the river, but according to research, Qu Zi is likely not jumping into the river. If you insist on telling it, it is actually not necessary.

Therefore, you cannot say that he changes history randomly. Moreover, what Huang Yifan is studying is not historical events, but historical figures. Research and verification can be carried out at any time, location, and what happened. But as long as you explain the character clearly, it is successful, and there is no random change or change. Besides, when anyone interprets a character, he will add his own evaluation and his own opinion. It is normal for a historical figure to have different performances in the eyes of different people.

Kong Rong and Cao Chong are both very smart and characterful in history. If we interpret them from the perspective of characters alone, Huang Yifan's lectures are undoubtedly extremely exciting. At least, even Zhou Binglin, who is not interested in Huang Yifan, admitted that Huang Yifan's interpretation suddenly made him remember to share Kong Rong and Cao Chong.

Especially the two stories Kong Rong and Cao Chong called each other, whether true or false, these two extremely classic stories will inevitably influence countless people in future generations. Maybe some schools will use these two stories to educate students soon.

However, he was a little unhappy when he asked Zhou Binglin to admit that Huang Yifan was powerful.

I have to think of a solution.

Although Zhou Binglin did not dare to question Huang Yifan openly, it was not impossible to secretly stumbling Huang Yifan.

After careful consideration, Zhou Binglin thought of a solution.

"My misfortune, yours."

Seeing Huang Yifan finally explaining what Cao Chong said, Zhou Binglin nodded: "The next class should be Cao Pi, and only Cao Pi inherited Cao Cao's position and became the founding emperor of Wei."

Zhou Binglin is a professor of history. Although the Three Kingdoms is not the one he studied most, he still has some understanding of the history of the Three Kingdoms. After just analyzing it, he guessed who Huang Yifan should talk about in the third lesson.
