Seeing the person who stood up, Li Shimin immediately smiled. As he expected, the first to discover the mystery was not the resourceful Fang Xuanling, nor the extremely smart Du Ruhui, let alone the scheming eldest grandson Wuji, or Kong Yingda, a generation of education masters, who was also excluded by Li Shimin. In Li Shimin's view, the one who is most likely to be the first to discover the mystery is Wei Zheng.

In fact, it was just as Li Shimin expected. There's a reason for that, ingenuity, let's not talk about this. The point is that only Wei Zheng is the kind of outright humble background. Only he can deeply understand the difficulty of having no money to buy pen, ink, paper and inkstone.

As for Fang Xuanling, Du Ruhui, and the eldest grandson Wuji, although they were not born into famous families, they were all born in wealthy families of official eunuchs, where did they have such an experience.

"Your Majesty, if the minister is not mistaken. This blackboard and chalk are both for teaching purposes. The blackboard replaces paper, chalk replaces pen and ink, and there is no need for an inkstone. Just like His Majesty just now, after writing, you can just erase it and write it again. In this way, except for some articles that must be preserved, there is no need to spend pen, ink, paper and inkstone at all. In this way, a lot of money can be saved, and countless poor children will no longer have to worry about the future. With these two divine objects, countless people who read will be added to my Datang, which is really a blessing for the country and a blessing for the society. ”

At this time, Wei Zheng's face turned red with excitement. He even directly raised the blackboard and chalk to the level of a teaching artifact.

In fact, there is only one key factor restricting Datang education, and that is money. Ordinary people simply don't have money to study. Therefore, there are very few scholars in the world, and most of them are from those clans, and a small number are from official families.

Looking at the current Manchu officials, in addition to those military generals, there are very few people like Wei Zheng who were really born poor, and there are very few of them.

"Haha, I really know that it will definitely be Wei Aiqing who can guess these things first. Wei Aiqing is right, this blackboard and chalk are for teaching. This chalk, of course, is used for writing. In addition, it is very cheap and can be manufactured in large quantities. The little table is for the students. The small blackboard on it is for students to practice words on a regular basis, and after writing, they can erase it and use it again, so that they can save a lot of pen, ink, paper and inkstone. This big blackboard is hung in the center of the school hall and used by Mr. for lessons. In this way, it will be easier for students to understand what Mr. is teaching. Kong Aiqing, you are a master of teaching, I don't know what you think"

After explaining the purpose of the blackboard, Li Shimin immediately asked like Kong Yingda. After all, they are the masters of this aspect, the real authorities.

"Your Majesty, the old minister is ashamed, ashamed. Such a simple prescription was never thought of after decades of teaching. As Master Wei said, it is not an exaggeration to call it a teaching artifact. With these two things, why can't you read and write. ”

This is a matter of plain sight, and anyone who hears it will know how useful the blackboard and chalk are. After Kong Yingda listened, he also sighed.

"Haha, that's the best, well, I still have a novelty here, please take a look."

The blackboard and chalk matter, Li Shimin stopped there. Then, suddenly, he spoke again. Everyone was curious to see what treasure the emperor was going to come up with. However, after a long time, I did not hear the emperor speak, nor did I see the guards bring things up.

Instead, he saw that the emperor actually picked up the chalk thing again, and then began to write on the blackboard again. It's just that the words this time are very different from the words just now, and everyone doesn't know them at all. It was like a ghostly talisman, crooked.

"Dare to ask Your Majesty, please forgive the old minister for being a shallow learner, I don't know what kind of writing Your Majesty has."

Not to mention ordinary people, even Kong Yingda, a master of learning rich and five cars, was also stunned when he saw these things. Then, he asked Li Shimin with a look of shame.

"Ah....... this is pinyin?"

However, there was one person who shouted out loud, and this person was Li Ke. That day at Yaya's place, he had also seen these ghost drawing talismans, and he also knew that this thing was called pinyin. It's just that at that time, he was completely fascinated by the three-character scripture and the hundred family names, and he didn't pay much attention to it. It wasn't until Li Shimin wrote these things again that he remembered them again. However, he couldn't figure out how Li Shimin could also know these things, and he was surprised for a while, and he lost his temper.

"Well, the King of Shu is right, this strange thing is called pinyin."

Li Ke was stunned at first, but he was quickly relieved. Then, he immediately affirmed Li Ke's answer.

"Pinyin?"

This is a word that everyone has never heard of, let alone know what it means. Everyone has a long insight today, first made a magical blackboard and chalk, and now there is a more inexplicable pinyin. Although they all wanted to know what this thing was for, they didn't say anything.

"Well, that's right, this is called pinyin, as for the use. Let me show you all Aiqing."

This thing is the same as the chalk on the blackboard, and it is a bit troublesome to explain, so it is better to demonstrate it directly, and everyone will know it clearly.

Subsequently, Li Shimin wrote down the word "Tang" on the blackboard, and then, as if he thought of something, he wrote down the three words "soup lying hot", and then he actually came to a live demonstration and spelled the pronunciation of a few words in pinyin. These are all things he asked Yaya for advice last night.

"Haha, this pinyin is good, better than that blackboard and chalk. According to this statement, I will not be afraid in the future. I found someone to mark all the books at home with this pinyin, then after I was old, I took out a book casually, and I could read them all, so we didn't also become a rich five cars, no, there are more than five cars of books at home, and ten cars can't be loaded. When the time comes......... Hehe. Well, and the same goes for the little rabbit cubs at home, Lao Tzu personally taught them to read and see what else they could say. ”

After watching Li Shimin's demonstration and listening to the commentary, Cheng Yanjin wanted to laugh out loud. At this moment, his old Cheng Ke was about to raise his eyebrows.

"God bless me Datang, blackboard and chalk can save a lot of money for people who read, so that more students can read, and this pinyin makes reading and reading easier. If you can mark all the books with pinyin, wouldn't it be that you can read all the books if you learn pinyin. Lao Chen implored His Majesty to teach the rest of the pinyin to Lao Chen, and after he returned, Lao Chen immediately set about all the books and marked them with pinyin."

This time, Kong Yingda is a little bit of a point, he has been teaching all year round, and he can understand better than anyone else the wonderful use of this pinyin. So, he immediately said to Li Shimin with excitement on his face.

In fact, after Li Shimin's field test, everyone also generally knows the usefulness of this pinyin. Just like Cheng Yanjin, he immediately thought of going home and marking all the books at home with pinyin.

"Hehe, Kong Aiqing, don't worry, this pinyin, sooner or later, I will teach it all to you. However, now, there is a more important matter to discuss with all Aiqing. Pinyin matters, I will have my own arrangements. ”

In fact, Li Shimin made so many things to serve the last thing. Besides, even if he wants to teach, he can't teach. Just these few pinyin, or Yaya taught him last night.
