I am engaged in construction in Datang

"One, the Arabic numeral is 1, and the capital letter is 壹. The capital letter was created by our owner and is mainly used in account books to prevent someone from changing the accounts. In life, when we talk about a person or a horse, we are using this 1." On the podium, Zheng Wen took a lime marker and wrote a few ones on the blackboard.

Today we should have talked about the order of addition, subtraction, multiplication and division, as well as several methods of calculation of special numbers.

But the owner said that since there was an honored guest coming to visit today, he had to start with the simplest explanation, otherwise when he explained 100÷(4x5)=?, the honored guest would not understand a single word.

Say it again, and the speed will be faster!

The farmers all know it, so Zheng Wen quickly explained how to calculate 100x99 more quickly.

The dealers in the audience kept nodding their heads. They understood and could apply the knowledge to calculate 100x101.

Li Shimin: "..."

"Ade, I'll test you when we get back."

Wang De: "..."

I have already started asking Feng Sanxi for help.

"What's that writing?"

"It's a blackboard and chalk. We can't produce them now, so I'll prepare one for you to take with you when you leave tomorrow."

The second class is a literacy class, and today we were supposed to talk about the Book of Songs.

Master Yu stood on the podium and said: "Today we will consolidate the phonetic symbols of Chinese characters."

Writing letters and tones on the blackboard, Master Yu pointed to a and said, "Come on, read with me, ah——"

"Ah——" in unison.

"Oh--"

"Oh--"

These people in the village also know how to do it, so Master Yu quickly went through the single vowels, the double vowels...

Started spelling.

Li Shimin: "..."

Why are others Mo Yi Aomiao, but he is Mo Yi Aomao?

"Ade, let me test you when I get back."

Wang De, I’m tired.

"Sister, can all the characters in the world be marked with pinyin so that people who understand pinyin can read them?"

"Of course." The current pronunciation is different from that of later generations. Li Yin added a lot of transpositions that were not found in later generations. If something really couldn't be expressed, she would just use the phonetic symbols.

In an age when 99 percent of the people cannot go to school, it is meaningless to worry about how to preserve elegant music.

"These need to be engraved and printed vigorously, and must be spread ten ways." Li Shimin couldn't wait any longer, he wanted all his people to be able to read.

A few people left without waiting for the night school to end.

Li Shimin suffered a great shock today. He returned to his residence, lit the biogas lamp, and wrote a few words on the rice paper with a brush. He didn't know where to start.

My sister said to take it slow.

Tomorrow I will talk to Xuanling and the others about the swamp pond.

Li Shimin tossed and turned until midnight before he slowly fell asleep.

The children in the village have to start their morning reading at 5:45 am, so the adults in the family also wake up. The village simply rings the gong three times at : am.

If a child is reluctant to get up from bed, the adults will ask someone to beat the gong to stand at the door and beat the gong.

If you stay in bed any longer, the adults will start picking up the broom.

At this time, Li Shimin was already sitting in the court.

He woke up at the hour of Yin and wanted to leave quietly, but when he opened the door, his sister-in-law and Manager Feng were waiting there.

When they arrived at the entrance of the village, Li Shimin was shocked.

The 32 guards he brought with him each had a small package containing five bars of soap, a bar of scented soap, and two taels of tea in a wooden jar. In addition, there was a pound of pineapple cakes, a new snack from the farm, a small jar of pickles, and a roast chicken.

You Qianniu gave ten bars of soap, three of which were scented soaps, and the rest were the same.

Each person was given five big buns and a pot of soy milk, which were said to be for breakfast. If they couldn’t finish the food, they had to take it away and leave it at home when they were hungry.

Wang De’s package was even bigger, half a meter high.

Not to mention Li Shimin, the village had an ox cart pulled over, and the blackboard was on the ox cart, along with a matching blackboard stand.

Li Shimin: "..."

I have been on the throne for so long, and I have always given things to others. This is the first time that I have brought other people's good things into the palace.

"Sister-in-law..." Li Shimin was moved again. The farm was preparing overnight!

"Brother, there is no need for you and me to say more."

"Okay, okay." Li Shimin wiped the tears from his eyes and said, "Sister, I will come again in two days. Please don't despise me."

"How could I dislike you?" Li Yin said, "I'm hoping that you will come to live in the village for a long time. Then life in the village will be more comfortable."

The two groups separated and went about their own business.

Xuanzheng Hall.

"If you have something to report, then stand up. If you don't, then dismiss the court..." Wang De had dark circles under his eyes. He hadn't slept all night. He was learning addition, subtraction, multiplication, division, and Chinese pinyin.

"Duke Liang, Duke Zheng, Duke Song, your majesty invites you." (Fang Xuanling, Wei Zheng, and Xiao Yu. Zhangsun Wuji is currently at home in mourning.)

Su Qing led the three of them towards the side hall.

After entering the room, Li Shimin stood in front of a black board with his back to the three people.

Su Qing brought the person over and then left.

"Your Majesty." After several people saluted, Li Shimin turned around.

"My dear ministers, do you know what this thing is?" Li Shimin pointed at the blackboard and said, "What can we possibly see from this thing?"

"Xuan Ling, please tell me."

Fang Xuanling's heart skipped a beat. There was something not quite right about His Majesty today.

After some consideration, Fang Xuanling said, "This board is as black as ink, about four feet long and three feet wide. It is placed in your majesty's study. It is quite different from other literati's calligraphy. I dare to guess that your majesty is using the ink board to warn yourself. Although the Tang Dynasty is becoming increasingly prosperous and powerful, and the people are living in peace, you must not be greedy for pleasure and stop moving forward because of this."

"Your Majesty is holy."

After Fang Xuanling finished speaking, the other two followed suit and shouted, "Your Majesty is wise."

"Hahaha..." Although he was flattered, Li Shimin was still happy in his heart: "In my eyes, this board is the future of the Tang Dynasty!"

It is not an exaggeration to say that it is the future. According to my sister-in-law, in the future, when teaching and educating people, a blackboard must be installed in the classroom.

"Look, everyone." Li Shimin picked up the chalk in the box and wrote three words on the blackboard -

Fang Xuanling.

Then he wiped it off with a cloth and wrote the names of Wei Zheng and Xiao Yu.

"This, this can actually be written repeatedly? So clear, and without leaving any traces!" Xiao Yu was shocked, and remembered a lot of things in an instant.

Teaching with this board is much more convenient and labor-saving.

Li Shimin was in a good mood and erased the names of the two people: "Wang De, pour tea."

"Your Majesty, I..." Wei Zheng didn't like boiled tea, which was sweet and salty with a lot of things in it. He preferred boiled water to quench his thirst.

Just as I was about to refuse, clear and bright tea was served.

"Xuancheng, try it first." Li Shimin picked up the teacup and smelled it, then took a sip, leaving a lingering fragrance on his lips and teeth: "I guarantee that you will like this new tea."

Wei Zheng picked up the teacup, and the liquid inside looked like light amber.

Taking another sip, the taste is indeed not as complex as usual, and the light fragrance is refreshing.

"Your Majesty, this..." Wei Zheng took a bite and was immediately conquered by the elegant taste in his mouth.

This kind of tea suits his taste!
