The master saw Wang Sixian stand up and answer for himself, and there was a bit of approval in his eyes, but when he saw that Wang Sixian had no words when he said this, his face darkened, and he no longer looked at Wang Sixian.

Instead, he looked at the others sitting with expectation and encouragement. Wang Sixian noticed the change in her master's expression, and the smile on her face was a little stiff.

A petite woman stood up and said, "Silk String is only half of what the master said. The Master's last sentence says that people and things are similar, but they are not identical. I think Silk String just said one aspect, Master should have the following. Another man got up and said heartily: "I won't talk nonsense, and then the wooden voice continued." I don't think it's the only way to make up for shortcomings, and if it's not feasible, it's not necessarily impossible. After all, things are dead, and people are created to achieve their goals. And people are alive, and the way of living is different. As for what the Master did not say, the students did not dare to speculate, this is a little opinion of the students. The master smiled and nodded to the man.

Li Yiwan stood in the last row, but she couldn't see the faces of the woman and the man, and secretly said that it was a pity. These classmates are good resources in the future, and they have not had a chance to make friends yet.

The Master motioned for them to sit down. looked at Li Yiwan with a smile again,

"Li Yiwan, what do you think?"

Yiwan felt that the voice was very correct with what the boy had just said. Yiwan just sighed just thinking that the ancients were really smart, we needed to hold water and have a wooden barrel, we needed to go out to have a carriage, and we needed to eat there would be a pot and spices, Yiwan only felt that the wisdom of the ancients seemed to be unable to see the edge, and she would sigh when she was ashamed of her stupidity. ”

"Why does Li Yiwan think she is stupid? I don't see that this girl thinks you're stupid, let alone ashamed of it. The master asked.

Yiwan couldn't figure out why the bucket was round, and why it was getting wider and wider from the bottom to the top. What are the processing procedures required to make the wood for buckets? There must be a difference between the water used and the water used to make the barrel. Li Yiwan humbly asked.

"Bell... Clang... "But it's time to eat after class."

"It's better for Yiwan to find the answer by herself. Other interested students can also take a look, and they can come and chat with Yiwan in the afternoon. Let's disperse. After saying this, the master departed with a smile on his face.

Well? Come and talk to me in the afternoon? Li Yiwan was not calm, and went out with Wang Xiaoshang to find leaves and oranges, so they went to a restaurant to eat at random, and the four of them went to the library pavilion.

Orange and Ye Zi stayed outside to wait, and after Li Yiwan and Wang Xiaoshang went in, they found many classmates in the same class, and they felt that there were about 20 people with a sweep of their eyes.

Of course, they all sat and read books in the 'work' department, and the two of them also hurried to find relevant books and make up for them, after all, few people would pay attention to the barrels.

Xu is the reason why many students are there, and for a while, the library pavilion is almost only in and out of people.

"Bell... Clang... The bell rang, Li Yiwan and Wang Xiaoshang hurriedly put the books back in their places and got up to go to class, and those classmates also rushed to the school together.

It just so happened that the master also happened to arrive at the door, so he stood on the podium and looked at the students who swarmed in, and laughed unconsciously, these students did not have a trace of just waking up, but were full of energy, probably for a person like a teacher, it is the happiest thing to see students come to class in high spirits and listen to the class attentively.

When everyone sat down and looked at him with a look of eagerness, the master smiled, it was good to be young. The master didn't sell Guan Zi either, and said directly: "What else does Yiwan not understand now?" ”

"Yiwan went to the library at noon today, and she benefited a lot, and now she has no doubts." Li Yiwan got up and said generously: "Yiwan only has the emotion of being impressed by the wisdom of her predecessors. ”

"Oh?" The master smiled, "Then let's talk about it." ”

"With the same circumference, the area of the circle is the largest, and the amount of water is the largest. As for why the bottom is narrow and the mouth is wide, it should be that the pressure of the water will be distributed to the vertical plank. As for the water used and the water used to make the wooden barrel, there should be a difference this, Yiwan thinks that the wooden barrel is only used to hold water, as for what the water is used for, it is natural to do whatever you want, it is Yiwan to drill the tip of the horns. Li Yiwan smiled shyly when she said this.

"Hmm. Yiwan, but that's it? The master looked at Li Yiwan with a smile, and Li Yiwan nodded. The master looked around and said, "What do the others have to say?" The man who stood up in the morning stood up and said, "The student thought that what he said this morning was complete, and he was a little complacent. Yiwan's problem today, the student is also confused, I never thought to go to the library at noon today, like Yiwan, I also feel that I have benefited a lot, only to know that the student is a frog at the bottom of the well, it is really ashamed. The man said ashamedly, but his voice was still the same as before, giving people a very sunny feeling.

"Huh?" The Master encouraged him to continue.

"It is too narrow to consider only the length of the plank, but also the diameter, the size of the bottom, the tightness of the hoop, and even the wood itself.

"Hmm." The master nodded in satisfaction, and glanced outside the school without a trace. The man continued: "And on a more concrete point, for example, if two people are at the same height, whoever has a strong background before them will have more nature, just as high as the vertical plate of a wooden barrel, and the one with a large bottom will naturally hold more water. There are many more, and students will not list them all. The man bowed respectfully to his master and sat down.

"No, you are very smart, and you will have your own future in the future. Anyone else want to say something? The master said with a smile.

It turned out that the boy's name was not heard. Li Yiwan said in his heart and remembered the name.

"Master." Wang Zizhe stood up and said: "Today Li Yiwan asked why the barrel is round, so I ordered someone to find materials and made a square one by myself, although it has the shape of a barrel, it is ......" As he spoke, Wang Zizhe took out the wooden barrel in his mouth...... Forehead..... It's like a wooden strip cuboid model without a lid.

Li Yiwan covered her mouth and laughed quietly. Wang Zizhe poured water from the cup into the square bucket again, and motioned to everyone,

"It can't hold water."

"Brother Zizhe has worked hard, Liu Neng is ashamed." Liu Neng stood up and said honestly: "But I have come into contact with these, whether the barrel can hold water or not has nothing to do with Fang Yuan, the wood will expand when it encounters water, and after it has been added, it will not leak if it is finally sealed with oil." ”

"Taught." Wang Zizhe shook his fist at Liu Neng.

"Brother Zizhe is polite." When the master saw this scene, he raised the corners of his mouth happily. Today's old pedant, if he disagrees, he will fight, no one will accept anyone, it is better to be a young man, he knows how to advance and retreat, and he still has the energy to do it, he remembered the time when he was young, and he was like them, eager to learn, hoping that he could stand out.

He laughed a little more often today.

"Master, there is something unknown about Silk String." Wang Sixian stood up and said.

"Speak." The Master nodded in encouragement.

"Siwan just mentioned that when the circumference is the same, the area of the circle is the largest. Silk String is stupid, and I've seen such a statement, but I don't know if this statement is really true? Wang Sixian looked puzzled and said innocently.
