Chen Zhou taught arithmetic and taught him arithmetic for several days.
For those relatively quick methods, teach them completely. Chen Zhou will give them a large number of example questions, go back and slowly work on the questions, and then collect them and explain them in a few days.
Xun Ji and Xun Yun have a certain foundation in mathematics. They have studied "Nine Chapters of Arithmetic" and it is relatively easy to get started. After getting the examples, they have not come to class for the past few days.
Only Xun Qiao is here, and she also wants to publish a book for Chen Zhou. Recently, she has been studying various mathematical knowledge with Chen Zhou.
Cao Shan and the others did not object to Xun Qiao's arrival, and even welcomed Xun Qiao to stay with her husband. They were quite satisfied with Xun Qiao.
Xun Qiao blushed easily when facing Chen Zhou.
But seeing Chen Zhou being so serious while she was having random thoughts, she felt very inappropriate, so she could only calm down slowly and continue writing this textbook.
Chen Zhou discovered that Xun Qiao was promised to help him, but in the end, he still needed to figure out many things. But it didn't matter. Thinking that modern mathematical knowledge would soon be spread in the Three Kingdoms era, he felt full of accomplishment. .
At this time, the Six Arts of the Gentleman also included mathematics. Most of Confucianism had not been led astray, and mathematics still had the opportunity to spread.
Chen Zhou didn't know whether he would be led astray in the future.
But as long as it is modified well in the Three Kingdoms, it should be able to be passed down later.
"Qiao'er, I noticed that you blush easily. Is it too cold? Can I have someone bring in another heater?" Chen Zhou said and looked at Xun Qiao.
At this time, Xun Qiao was still blushing and her cheeks were slightly hot. When she heard Chen Zhou's words again, she couldn't help but exclaimed and reached out to touch her cheeks. This was not because she was blushing from the cold.
But it was really hot.
"No... no need!"
Xun Qiao had the nerve to ask why he was blushing, and shook his head: "I'm not cold at all."
"Is not It Cold?"
Chen Zhou stretched out his hand and probed Xun Qiao's forehead.
Such an intimate gesture made Xun Qiao stiffen, and then she felt secretly happy. However, thinking about it again, it seemed a bit unethical. In short, all kinds of thoughts appeared in her mind.
Xun Qiao couldn't hold back his wild thoughts at this moment.
"It doesn't look like a fever either."
Since he wasn't red from the cold, Chen Zhou thought he might have a fever.
However, although the temperature on Xun Qiao's forehead increased slightly, it was not yet at the level of a fever.
"I am okay."
Xun Qiao lowered his head and gently pinched the corners of his clothes with both hands.
For a moment I didn’t know what to do.
Just when Chen Zhou was still asking what should be done, Cao Ang came and said that the shop was ready.
"Qiao'er, let's go out and take a look."
Chen Zhou said.
Xun Qiao nodded briskly and followed Chen Zhou to the market in Xudu.
The shop prepared by Cao Ang is in the best location in the market. The books have been delivered long ago, and the shop is decorated similarly.
Although it is still very cold outside, inside the city, there is a city wall that blocks part of the wind, so the wind and snow are not very strong. Now the wind and snow have stopped again, and it is no longer snowing.
On the street, you can also see people responsible for clearing snow.
Clear the snow to make it easier for pedestrians, vehicles and horses to pass.
When Chen Zhou and the others came out of the carriage, they could feel the coldness coming over them.
"Is it cold?"
Chen Zhou glanced at Xun Qiao, who was shaking slightly. He took off his cloak and handed it to Xun Qiao to put on.
When Xun Qiao saw this, his cheeks turned redder and he whispered: "Sir, how can this... be possible?"
Chen Zhou put his hands on her body and said, "You're welcome in front of me."
Xun Qiao could feel the warmth left by Chen Zhou from the thick cloak, as well as the strong manly breath, and felt that he was about to fall.
Just when she was about to say something, she saw Chen Zhou following Cao Ang into the shop.
Chen Zhou quickly looked at the store and said: "The layout does not need to be too complicated. Next, let's send out a message and tell everyone in Xudu City that there are books available here. If the poor families and ordinary people who come here can let us distinguish their identities, they will all You can give them a book for free, and they can choose whatever book it is.”
Anyway, printing books now doesn’t cost much.
If you really don’t have any money, you can still ask Captain Mojin to dig for it. Captain Mojin has been idle for a while and needs to get busy again.
"good!"
Cao Ang knew what to do.
With the Cao family's status in Xudu, it was very easy to spread the news here. Within half an hour, several scholars from poor families came to ask about the situation.
When they saw the paper books printed by the Cao family, they exclaimed that this kind of book was so useful.
But Chen Zhou had a rule that each of them could only choose one book. Those poor scholars each picked a book, took it and left. They really didn't need to pay.
"Thank you, eldest son!"
They all faced Cao Ang and bowed deeply.
Because Cao Cao selflessly provided food when there was a shortage of food before, the Cao family's reputation in Yingchuan was very good.
Now Cao Ang also gives away books for free, instantly gaining favor in front of the poor family.
Those scholars from poor families took the initiative to help Cao Ang with publicity after they returned. As soon as these people left, other people came one after another. Most of them were scholars from poor families, and of course some were scribes from aristocratic families.
People from aristocratic families mainly heard that books are sold here, and poor families and ordinary people can get them for free.
Aristocratic families with heirloom poems and books were disdainful of receiving them for free. They just heard that these books were very special and came to take a look at the fun.
Those poor families and ordinary people who do not have poems and books passed down from their families have a thirst for books.
Anyone who wants to read is eager to get books.
This shop quickly became busy.
They saw that the books Cao Ang sold were not bamboo slips, but light paper books, which directly refreshed their understanding of books. Shouts of surprise continued to come from the store.
Even scholars from aristocratic families cannot help but buy one or two copies here at a high price when they see paper books.
Chen Zhou and Xun Qiao stood outside the door, looking at the bustle inside and listening to the exclamations. Chen Zhou had expected this and didn't think it was anything.
However, when Xun Qiao saw this, he fell in love with Chen Zhou.
Xun Qiao admired Chen Zhou's resourcefulness and ability.
"Wat it!"
At this time, Cao Cao heard the news and came.
"Lord!"
Chen Zhou and Xun Qiao said at the same time.
Cao Cao looked at Xun Qiao, who was following Chen Zhou like a little tail, and his mind became active. He felt that he had to chat with Xun Yu if he found time, and said: "I heard that you are selling books here, help me fight back. Come and take a look at those sarcastic comments."
Recently, Mi Heng has set the pace so high that throughout Yingchuan, scribes from aristocratic families who are not part of Cao Cao's faction are constantly mocking Cao Cao's Imperial College.
Even Cao Cao felt very unhappy after hearing this. He almost couldn't hold it back and was about to kill someone.
However, he heard from Cao Ang that Chen Zhou had a way to fight back. Cao Cao's unhappiness disappeared immediately. He thought that if Chen Zhou was going to fight back, those mocking families would soon be slapped in the face.
