The day after Li Gang and Yan Shigu were about to take punctuation, Xia Hongsheng called Yan Shigu again and told him that he wanted him to start teaching punctuation and sentence breaking in the Hongwen Pavilion, and had reached an agreement with Kong Yingda that Guozijian would also send students to listen to the lecture and learn the method of punctuation and sentence breaking, and bring it back to Guozijian and then teach it to Guozijian students, and first promote this method from Guozijian in Hongwen Hall to try, and then promote it to various Taoist museums.

"Master Yan, if you really want all students to master this punctuation and sentence breaking method, there is only one way, that is, to include it in the requirements of the imperial examination. Xia Hongsheng didn't have much feeling about letting him teach these students punctuation, these things began to be learned and contacted in the first grade of primary school in the later world, and the Chinese that Xia Hongsheng himself learned in the later world was a teaching language, not a problem. Moreover, who else in this academy knows more about punctuation and sentence breaking than him, so he is not surprised that Yan Shigu let Xia Hongsheng come to accept it. Compared with this, he is more worried that this method cannot be implemented locally, especially in addition to the official schools of various provinces, those students in private schools and even self-study, their number is larger, if there is no hard requirement, so that they have to master this method, then it is likely that this method is like the ancient "Mandarin" - official dialect, there is no way to completely promote the whole country.

Yan Shigu nodded: "This old man is provincial, but this is not an overnight thing, nor can it be completed by an order, which involves many aspects, this is the current book, it needs to be marked with punctuation, and then published in the world, this problem alone, how difficult it is." It's not too difficult to edit and add punctuation, it can be done for dozens of years, just print...... These things have their own old men to worry about, Jingshi doesn't care, just leave the Hongwen Pavilion and the students of Guozijian to the church, and leave the rest to us old men to have a headache! You can rest assured, the matter of punctuation marks and sentence breaks involves tens of thousands of readers, and it is also related to the inheritance of literature and Taoism, which is a thousand-year plan, and the old man will definitely make him! ”

Hearing Yan Shigu say this, Xia Hongsheng didn't ask anything more, as long as they could clearly understand the importance of punctuation and sentence breaking, then it would be fine. These bigwigs are more adapted to Datang's rules than themselves, and they know how to accomplish this under Datang's rules.

Yan Shigu explained a few words to Xia Hongsheng, then gave Xia Hongsheng a leave and asked him to go back and prepare well, and when the people from the Guozijian came the next day, they would start talking.

Xia Hongsheng actually doesn't need to prepare, he is too familiar with these things, and he can't be more proficient in how to talk about them, and he can even recall the smooth punctuation marks, so there is nothing to prepare for in this regard, but if you want to make the class intuitive and easy to understand, some other things must be prepared. Xia Hongsheng was still a little worried before, just standing there in such empty words, he might not be able to explain clearly, he had a day to spare, but he could try to make the necessary things.

In fact, it is not a very valuable thing, it is nothing more than a blackboard and chalk, although these two things are not valuable, but they are absolutely indispensable things for education. As the saying goes, it is better to draw and write a thousand words, some things are not transparent to say, draw a picture on the blackboard, write a write, for example, intuitive and clear, students will be easy to understand. Moreover, it is written on the blackboard, and students can see that it is definitely much better to memorize while reading and listening to the explanation, which is definitely much better than listening with only two ears.

The blackboard is easy to say, but you can't get it complicated, and it's still okay to make a simple blackboard. Find a carpenter to make two legs, and put a wooden board on top of it, and the wooden board is painted with black lacquer, although the effect is not as good as that of later generations, but it can still write things, and this is it. As for chalk, Xia Hongsheng was a little confused. At the earliest, chalk appeared in Europe, and it is said that it was written with lime mixed with a little water, made into a block, but adding water to lime will not heat up and corrode people? And even if it is done, the lumpy lime block hurts your hands, and it is easy to scatter when you write, which is inconvenient.

However, we are human beings, we are flexible people with intelligence and understanding, and the spirit of all things comes, and this little problem is difficult for us.

If you can't write white characters on a black background, you can change it to black characters on a white background!

Isn't it okay to brush out the white ash directly, make the blackboard into a whiteboard, and then cut the charcoal into strips to replace chalk for writing, and use it temporarily? In the future, who will figure out what ingredients are added to the chalk, and then it will be good to reform, and generally leave some opportunities for future generations, right?

Xia Hongsheng persuaded himself like this, so he hurriedly went back and called Qi Yong and a few people to come, and ran straight to the West Market.

When I arrived in the West Market, I found a carpenter and explained my intention, how easy this wooden frame is, even the materials are ready-made, and the outline of the blackboard is typed out according to what Xia Hongsheng said. It's a pity that there is no white ash in the carpenter's place, so he can't brush it up. At this time, the benefits of being a nobleman were reflected, Xia Hongsheng just said, and there was a personal soldier who knew where there was white ash, so he took two people to carry it and went to find it. Xia Hongsheng instructed the other two soldiers to buy charcoal, and after buying it, they all went back and cut it into strips one finger long and two fingers thick, and the charcoal was also soft and crispy, not durable, and not thick. And the two soldiers took the order. Xia Hongsheng took Qi Yong with him, sighing that it was really easy for nobles to do things, and went home and waited.

When lunch was ready, the soldiers came back, carrying a white-gray blackboard in their hands, and the other two each carried a bag of charcoal.

After an afternoon of exposure to the sun, the white ash was completely dry, Xia Hongsheng tried it, and it was very conspicuous to write, and the goal was achieved. As for wanting to wipe it off, wipe it directly with a damp cloth, the charcoal is not written on it for a long time, and it can be wiped off, and the white ash is dry, it's fine.

The preparations were done, and in the early morning of the next day, several pro-soldiers carried the blackboard, and Qi Yong carried the sharpened carbon strips on their backs to the Hongwen Pavilion.

A group of students came around, not knowing what Xia Hongsheng put under the shade of the tree, and they didn't know what they were used for. At the end of the morning class, Xia Hongsheng walked out of the school room, and saw Yan Shigu and Li Gang looking around the blackboard, and raised their hands to knock, very curious.

Xia Hongsheng walked over and saluted the two, Yan Shigu waved his hand and said, "Hehe, Master Li and the old man have time today, so let's take a look at how you teach other students." The students of Guozijian will arrive later, and Jingshi is fully prepared? And the rest assured lecture is that the old man and others are next to him. ”

Xia Hongsheng was relieved, this was because Yan Shigu and Li Gang were worried that the students would not be convinced that he would come to teach, so they came to give him a town in person. So Xia Hongsheng saluted again and thanked: "The student thanked Master Yan and Master Li!" The students are well prepared, please rest assured that Master Yan and Mr. Li are assured. ”

Yan Shigu stroked his beard and nodded, then asked with a smile, "Jingshi, I heard that you got this thing?" What is it, and what is it for? ”

Xia Hongsheng gave a respectful salute and replied: "Back to Master Yan, yesterday Master Yan ordered students to teach the method of punctuation and sentence breaking today, and the students pondered, these things are inevitably vague only from the mouth, and it is far better to write them on paper intuitively and clearly, but if you look at the paper and write, so many students can't take care of it, and not everyone can see it." So yesterday, when Master Yan asked the students to prepare, the students went to find a craftsman to make this thing, this whiteboard is equivalent to paper, and the students use carbon strips instead of pens to write on it, so that the things explained are intuitively presented on the whiteboard, so that all students can see it, and it is easier to understand when learning. ”

After speaking, Xia Hongsheng took out a carbon strip from the package hanging on the leg of the whiteboard, and then raised his hand to write a line of words on the whiteboard: Minke, make it; No, let it be known. …… All with punctuation marks at a glance.

"This thing...... If it is a teaching aid, it will be very beneficial for lecturing! Li Gang and Yan Shigu glanced at each other in surprise and said. They all saw the surprise in each other's eyes, both of them were people who had been teaching and educating people for most of their lives, Xia Hongsheng wrote this, and immediately saw the wonderful use of these two things.

"Jingshi, half a day's work, in order to facilitate the teaching of punctuation and sentence breaking, you came up with such a teaching aid?" Yan Shigu looked at the whiteboard in surprise, and then looked at Xia Hongsheng: "It is said that there are seven exquisite hearts in the world, could it be that you can't do it?" With this kind of teaching aid, no matter what else is taught, wouldn't it be possible to use it and let the students see it directly?! ”

"Students feel that it is difficult to understand just by speaking, and it is far better to understand it at a glance than to write. This thing is very simple to make, the cost is also small, it is very suitable for teaching in the school, just find a carpenter to see. Xia Hongsheng replied: "This whiteboard, students want to stay in the library so that the gentlemen can teach, I don't know if it can be?" ”

"Very good!" Li Gang stroked his beard and smiled, and Yan Shigu also smiled and nodded approvingly to Xia Hongsheng.

Yan Shigu and Li Gang tried to write on the whiteboard a few times, and felt that this kind of teaching aid should be of great use, and immediately decided to equip it in the Hongwen Hall in the next few days. As he spoke, he saw the guards of the Hongwen Pavilion in front of him leading a group of people dressed as scholars to come over, and the students of Guozijian arrived.

Xia Hongsheng's first class after crossing over to the Tang Dynasty is about to start. Thinking about it like this, I'm really a little excited!
