Chapter 77 Teachings of Later Generations
Chao Chao looked at him running away and asked worriedly, "Is Brother Yuanyuan angry?"
"No, I'll see him again later, he will definitely be smiling."
He Zheyan said, holding Chao Chao's hand and walking out, "Let's go to the study."
Chao Chao nodded obediently and walked a few steps. After thinking for a while, she asked in a low voice, "Cousin, car, did you assemble the car?"
He Zheyan smiled and patted her head, and whispered, "Chao Chao is really smart, but just pretend you don't know and don't expose him, otherwise your brother Yuanyuan will lose face."
Chao Chao nodded vigorously, "I know, I won't tell him, so he will be very happy."
He Zheyan looked at the little girl with a gentle look, and felt uncomfortable when he saw her pursed lips seriously. How could his smart, cute and sensible sister have to meet those inhuman dogs?
When he finds Shangliu Village, he will definitely teach those people a lesson.
As the two were talking, they slowly walked up to the third floor.
He Zheyan has his own study here. Although it is not as big as his grandfather's, it also covers a wide range of books. Yuanyuan is young and temporarily shares a study with him. At this moment, he is already sitting in the study, pretending to read a book.
When he saw the two people coming in, he immediately snorted. But the next moment, he still moved aside with his books, giving up half of his small table for Chao Chao to share.
He Zheyan saw it and smiled.
Chaochao didn't see it, she was very nervous at the moment.
When she saw the bookshelves on three walls after entering the room, her breath stopped, especially when she saw that they were filled with books. She was even afraid to move around, for fear that if she moved too much, she would accidentally break something in the study.
Therefore, she almost walked by holding He Zheyan's hand.
Even when He Zheyan pressed her shoulders and forced her to sit on a small chair, she was still very reserved.
He Zheyan walked over to the small bookshelf and looked through it, found a digital picture book that Yuanyuan had used before, then took a blank notebook and a few pens, and sat down cross-legged at the small table next to Chao Chao.
"Chao Chao, let's start with the simple things and learn numbers first. Chao Chao? Chao Chao? What's wrong with you?"
"No. Nothing." Chao Chao hurriedly shook his head, then nodded, "I suddenly remembered that I need to go wash my hands."
After saying that, he stood up, tiptoed out of the study, and went outside to wash his hands.
He Zheyan, "..."
In fact, there is also a bathroom in the study.
Chaochao had been out for a long time. When He Zheyan was about to doubt whether she didn't want to study, she came back, raised her little hands, and walked to the small desk and sat down again, as if she didn't dare to touch anything else.
Then he took a deep breath and said very solemnly, "I'm fine."
He Zheyan, "..."
He couldn't help but hold his forehead and shook his head with a smile, but he didn't say anything. After knowing Chaochao's experience, he more or less guessed that learning might have been a very rare thing for Chaochao in the past.
In fact, Chao Chao is not the only one who has this mentality. Most of the people in Daqi under the sky think that this is the way it should be.
Not only those poor families who may never touch a book in their entire lives, but even many readers from well-off families feel that washing hands before reading is the most basic requirement.
Seeing Chaochao coming back after washing his hands, they nodded seriously.
However, after Chaochao sat down, they couldn't help but stretch their necks to see how they taught.
He Zheyan moved the picture book in front of Chao Chao and said, "Come, let's learn ten numbers first."
He pointed at the picture book and taught Chao Chao to read it, then picked up a pen and wrote down the ten numbers on the notebook.
As he wrote, he said, "These are called Arabic numerals. The ten numbers from zero to nine can all be written with one stroke. Isn't that easier to remember? Let me tell you another interesting thing. These ten numbers, with one stroke added, can all become eight."
As he spoke, he added up all the numbers.
Chao Chao widened his eyes in surprise, "Really? This is amazing."
Although the number eight becomes weird and twisted after some additions, it is indeed eight.
"Chao Chao, do you want to try it yourself?"
He Zheyan gave her the pen. Chao Chao didn't dare to touch the pen at first, but now she couldn't control her curiosity, so she took the pen and carefully drew on the paper.
It took her almost no time to learn the numbers.
Not only her, but all the people of Daqi under the sky were also learning, especially many ordinary people who could not afford to go to school. At this moment, they were almost eagerly following along. Some of the more quick-witted ones were already using tree branches to gesture on the ground.
"This cousin is really good at teaching. I always thought I was pretty dumb, but I didn't expect that in such a short time, I have learned ten numbers."
"Me too, me too. From now on I can be considered a literate person, hehe."
Some people also poured cold water on the idea, saying, "What's the point of learning these numbers? These are characters from later generations, and they are different from ours. Even if you learn them, you won't be able to use them in the future."
"Who said that? Now everyone can see the sky curtain and follow suit. Isn't it the same?"
This made sense. The man had no words to refute, so he could only snort coldly and leave.
There were also many educated people who followed suit. Compared to ordinary people, they already had a basic understanding of reading and writing, so they naturally learned faster. "These numbers are easy to recognize, write, and remember. They are much more convenient than what we have now."
Especially the numbers after ten, which can be completed in two or three strokes and do not take up much space.
Emperor Jingxuan had already written down these numbers on the paper in front of him, but as he looked at them, he couldn't help but frown.
After a while, he sighed and said, "It's true that Arabic numerals are simple and easy to remember, but because of this, they are too easy to be tampered with."
Didn't you see what He Zheyan did just now? All the numbers can become eight.
Chaochao didn't have as many ideas as Emperor Jingxuan, but after she learned the numbers, she went to look at the picture book. As she looked at it, she found that there was a small character at the bottom, which looked very complicated.
She had questions, so she pointed at the word and asked He Zheyan.
The latter explained, "This is a capital number. Doesn't it look difficult?"
Seeing Chao Chao nod, he smiled and said, "Our ancient scholars used this font. Although we use it less now, it is very practical in some important occasions. For example, some certificates and contracts will be written with uppercase numbers after the Arabic numerals to prevent tampering. As long as the Arabic numerals and uppercase fonts are consistent, there will be no problem."
