Poor Ghost Up and Down 2000

"Oh, my face was scarred by a sharp weapon in my early years, and my face is terrifying. That's why I always wear a bamboo hat, so as not to scare others."

She didn't intend to let Cao Cao see her face. Although she was very helpless, she had to say that this face was indeed inconvenient.

After all, if she wants to stay here for a while, it is better not to let others see her face, otherwise a person who is not old will always make people think differently.

"Hahaha." Cao Cao said with a smile: "Sir, what kind of person is he treating Cao? How can Cao judge a person by appearance?"

"But since it's inconvenient for you, sir, please be at ease."

Cao Cao no longer delved into this matter, turned his hands away, took a deep breath, and grinned: "Today is really a pleasure, let's have a drink."

"Come here, sir, and drink three hundred cups with Cao, you and I won't go home until we're drunk!"

After speaking, he laughed and walked out, regardless of whether the three hundred cups could be drunk or not.

Gu Nan stood in the hall, looked at Cao Cao's back, and smiled.

Would you rather call Qing Shi notorious and be regarded as a hero of the whole life?

A hero in troubled times should be like this.

Thinking of leaving slowly in the hall.

Among Nanyang.

In a thatched cottage, a young man in white was sitting in front of an old man who looked to be half a hundred.

The old man had gray hair on his temples and was wearing an earth-colored blouse. He looked like an ordinary old farmer, but the young man in front of him was respectful.

The old man looked around the boy's study, and said with a smile: "Young friend Zhuge, this place is clean."

The young man in white robes sitting in front of the old man saluted and said.

"It's just a shabby room, Mr. Hui laughed."

"Whether it's a shabby room or not, how can it be told by others?"

The old man touched his beard and smiled, his voice was a little hoarse, but his attitude was easy-going.

While speaking, his eyes fell on a painting hanging on the wall of the room, which depicted landscapes, fields and four people.

His eyes fell on the eyes of the old man in the painting, revealing a bit of surprise.

"Little friend Zhuge, is this what you drew?"

The young man in white followed the old man's gaze to the painting on the wall behind him, looked at the painting with a slight smile on his face, and nodded.

"It's just a landscape."

"It looks like a landscape, but what is painted is a person."

After all, the old man was old, so he saw the look of the young man, took a sip of the tea in front of him, and looked at the landscape painting that the young man said.

"My little friend's work is beyond the ordinary, and it can be handed down to the world. I saw my little friend's obsession with Shuofang girl before, and I was worried about my little friend's obsession. Now it seems that I am worrying too much."

The boy in white looked at a person in the painting, a little lost in thought.

"Shuofang girl is a scene I have never seen before, and the only thing I can paint is the people in this farmhouse."

"It's best if you can figure it out."

The old man put down the teacup and took out a piece of paper from his arms.

"Regardless of other matters, I don't know about the knowledge of Gewu mentioned in the letter sent by my little friend last time. After studying for a long time, I still haven't been able to understand it. I only got a little. It's really amazing , This time I came here to ask boldly, how did this little friend Gewu know?"

Chapter 299: So we must have a scientific spirit

The knowledge of Gewu, it is not that the old man has never heard of the term Gewu before, and the word Gewu is found in the Book of Rites.

"Book of Rites·University" records: To know is to investigate things, and then to know things.

It is said that if a person wants to cultivate Qi Zhiping and bright virtue in the world, "investigating things" is the foundation of merit and the beginning of "the way of great learning". Improper "investigation of things" means "knowledge" is unclear;

However, few people have clarified the meaning of the term Gewu. Many academic theories have their own explanations for the term Gewu in ancient times. They talk about it separately, and there is no unified statement.

Even he himself is a little confused about what is to study things and what is to know.

And what is the income?All are unknown.

However, in the letter sent by little friend Zhuge in front of me recently, there is a completely unheard-of explanation for Gewuyi.

It is the principle of investigating things as studying things.

The idea is to correct people's behavior in order to explore the truth of things.

After explaining the term Gewu, Zhuge Xiaoyou also raised several questions in his letter, what is air pressure, what is friction, and what is heat transfer.

He had never heard of these words at all, and the phenomenon mentioned in the letter, which was used to explain it, also surprised him.

One is to pour water into the furnace and burn it, and when the water is boiling hot, the furnace cover will move.

No one touches it, so what force makes the furnace cover move, it is said to be air pressure, the power of Qi.

But what is air pressure, and how can we see the power of air?

The two are to merge the two books by pages, and the pages overlap each other, and the books cannot be opened as much as possible.

He tried it himself, but the pages of the book overlapped, and the thin paper was so heavy that he couldn't pull it apart for some reason.

The force in this is called frictional force, and he can't explain what this force is.

The third is that the bottom of the cooking utensil is burned in the fire, and then the mouth of the utensil can gradually feel hot when the hand touches it.

If the fire burns at the bottom, why the upper part will also be hot? This is called heat transfer, and it is another incomprehensible vocabulary.

Some of these three questions are what we see every day and are used to, but no one has ever corrected their reasons.After thinking about it, I found out that I didn't know the root cause.

Some whimsical ideas make people surprised and puzzled.

The principles of the three things make people confused, but they all faintly make people feel that there is a root of the law, and if you can get it, you can get the truth of things, the way of the university.

After reading the letter, the old man has been thinking all day long.

It's not staring at the boiling teapot in a daze to explore strength.

There "tear the book" and observe the cookware for friction and heat transfer.
