I am engaged in construction in Datang

"This is a systematic measurement system! And it can be converted into each other!" Li Shimin was envious. If this set of units became popular, the people would have a deeper sense of identity with the Tang Dynasty.

Perhaps this set of units will be used for hundreds or thousands of years to come.

Look at the ambiguous and frequently changing units nowadays. In the words of my stepsister, it is not conducive to experiments and research.

Li Shimin was also aware of this. During the Qin and Han dynasties, the volume of one liter was only about one-third of what it is now, and the volume of one foot has changed even more, from about 24 centimeters during the Three Kingdoms period to 30.7 centimeters now.

If a farming book is published in the future and says that the ditch should be dug two feet deep, would that be 50 centimeters or 60 centimeters?

"Brother, there's no need to rush. We can just take it slow." Li Yin said.

"All the good things in the village use this set of measurement units. If others want to use, learn, or buy them, they must learn it. Gradually, everyone will discover the benefits of accurate measurement and will spread it spontaneously."

"What my sister said is right." Li Shimin sighed. How could my sister, who was only in her teens, know so many things?

The more I thought about it, the more amazing it seemed: "Sister, you know so much..."

Li Yin smiled faintly, her eyes revealing a divine light that showed she was calm in the face of adversity: "Brother, have you ever heard of a story called "The Pillow Trick"? "

"There was a Taoist priest named Lu Weng... Sheng was stunned for a long time, then thanked him and said, "You know everything about the ways of honor and disgrace, the fortunes of poverty and success, the principles of gain and loss, and the feelings of life and death. This is why you are trying to stop me from wanting to learn. How dare I not accept your teachings! He bowed twice and left."

Li Yin drank some tea to moisten her throat and changed the characters and time of the story.

Li Shimin and the other two were still immersed in the story.

"Brother, the people in the book got a jade pillow but it was all just a dream. I have been in chaos and stupidity for thirteen years since I was born. My soul went to a foreign land to practice. Now I have just woken up from the dream."

At this point, Li Yin began to feel uncomfortable. She woke up, and Aong left with peace of mind.

Fortunately, she came, otherwise Aung would not be able to leave in peace.

Not many people in the manor knew that she was mentally retarded, only Xiaochun and four other maids who had taken care of her all year round. Grandfather was afraid at that time, so he left a lot of guarantees for her.

"Hiss——" Li Shimin took a breath of cold air.

He had always believed in ghosts and gods, and always thought that those natural disasters were God's punishment for his usurpation of the throne. But now he met a strange person like Li Yin.

"Sister-in-law!" Li Shimin's eyes reddened and he held Li Yin's hands.

"You, you are sent by God."

I am right!

You all say that I was wrong, but if I was wrong, why would God let my sister come here?

Li Yin also took the opportunity to hold Li Shimin's hands tightly, looking excited.

"Brother!"

"Stepsister!"

Wang De: "..."

Feng Sanxi: “…”

That's enough, you two.

Then the two glanced at each other and wiped the non-existent tears from the corners of their eyes.

The warm atmosphere quickly cooled down with Xiaochun's arrival.

It was getting dark and time for lunch in the village canteen.

"Brother, it's getting late. Why don't you stay at the farm tonight and leave tomorrow morning?"

"That's good." Li Shimin was just about to take a look at what the night school at the women's farm was like.

"Wang De, go and ask someone to go back and pass on the message."

"Manager Ade, please wait a moment." Wang De was about to go out to call someone when Feng Sanxi ran over with a few people.

"Zhuangzi has prepared some food. I didn't know that there were brothers on duty outside before. Now I know. We can't let them go hungry. Let's go together."

"Ah, Master Li is so thoughtful." Wang De sighed repeatedly, look at him!

We don't want to leave!

Feng Sanxi brought four attendants with him, one of whom carried two large baskets covered with cotton cloth, and another carried a covered wooden barrel.

I don’t know how many people are hiding out there, so it’s always better to be prepared.

The six people walked out of the manor. Wang De didn't hide anything at this time. The things in the manor are more powerful than those in the palace. Others don't guard against us, so why should we guard against them!

His Majesty has acknowledged her as his sister!

Wang De called out the people who were hiding, a total of thirty-two people.

The Right Captain, who had received the order, was about to ride back to the palace, but Feng Sanxi forced him to eat three large meat buns, two vegetarian buns and a pot of soy milk.

"Chicken buns. There are so many of them in the village. It would be a pity not to eat them."

"Thank you." You Qianniu felt warm in his heart and clasped his fists.

Feng Sanxi finished speaking and then said to the remaining guards, "There are too many buns to eat at the farm. You guys can eat the meat ones first. They are hot. Leave the vegetarian ones for roasting when you get hungry in the middle of the night. There are two soups, one sweet and one salty. There are plenty at the farm. When you are done, send someone to get them at the farm."

The buns in the village would get cold by the middle of the night, so whoever wanted to eat them had to heat them up themselves.

The remaining 31 people on duty were happy. They thought they would have to eat dry biscuits tonight, but they ended up having big meat buns and hot soup!

The village provides bowls and chopsticks. You can't give people food without providing them with bowls and chopsticks. That would be disrespectful.

"It's mutton soup! There's mutton and mutton offal, with vermicelli and kelp." A guard scooped out something from the bowl and picked up a piece of kelp: "What is this? Why haven't I seen it before?" (Kombu is different from kelp. Kelp is not available at this time, but most people now regard konbu as a type of kelp, so it is collectively called kelp)

"That's called Qian Zhang." Xiao Yang took a look and said, "That was invented by our owner!" (There are records of Qian Zhang in the Tang Dynasty, called Yupi, but it is not the same as the thick Qian Zhang we have now, and it was not widely circulated in the Tang Dynasty)

"Little brother, Qian Zhang is delicious. Do you sell Liuweizhai?" Everyone knows that Liuweizhai is run by a woman.

"Sell. It's hard to store thousands of them. We made a small amount. They were sold out as soon as the West Market opened."

"We'll buy some to try later."

Wang De, Feng Sanxi and others put down their food and returned to the village.

After everyone has finished eating, just put the food at the entrance of the village and someone from the village will come to collect it.

Over there, Li Yin took Li Shimin to wash his hands. She gave Li Shimin a new piece of osmanthus-scented soap, a new towel, and glycerin.

"Sister, what is this called? It smells good and washes hands clean. Can it be used to wash your face? And this hand wipe, can it be used to wipe your face?" Li Shimin imitated the people in the farm and first wet his hands with water, then applied soap, rubbed them back and forth to create bubbles, then rinsed them with water, wiped them clean with a towel, and finally applied glycerin.

It's so exquisite! Even more exquisite than when he was in the palace.

"This is called soap. It can be used to wash your face, but it has more uses." Li Yin wiped her hands and applied glycerin: "If someone is injured and there is no alcohol on hand, they can wash with soapy water first. Soapy water can also kill bacteria, induce vomiting, reduce swelling, and relieve itching... Soap does not have the fragrance of soap. It has a stronger smell and a fishy taste. It is used to wash clothes in the village."

Li Yin handed Li Shimin a piece of soap: "The uses and effects of both are actually the same. Glycerin is used to wipe hands, and it can also be used to wipe the face, mainly to prevent skin cracking and frostbite."

The two of them walked and talked, and sat at the dining table, this time it was a small table for four.

We also ate buns and drank mutton soup.

"Sister, is it difficult to teach adults to read?" Li Shimin had another idea. If everyone in the Tang Dynasty could read and write, who would care about the aristocratic families?

"It's neither difficult nor not difficult. It depends on what method is used." The current Mandarin is the elegant pronunciation popular among high-ranking officials and nobles during the Qin and Han dynasties. The elegant pronunciation of the Tang Dynasty retained some Hakka and Chaozhou dialects, and also integrated the pronunciation of Luoyang.

Each subsequent dynasty has been changing. It sounds good, but it is very chaotic. It is not easy to unify when it is chaotic.

It doesn’t matter how the dialect changes, but how can the official language keep changing?

We haven't learned it yet, and it's going to change again. Then we might as well not learn it. You send an official who doesn't understand the dialect. We can listen if we want to, and say we don't understand if we don't want to.

Now people praise people by saying "Sao", but in the Song Dynasty a few hundred years later people would praise people by saying "Zhong", which is the official language! (Don't worry about the ancient titles. In fact, the emperor didn't call himself "Zhen" in spoken language. "Zhen" was written in written language, including "I", "Wu", "Gu", "An", "We", etc. So there is no need to worry about the names of things, such as kelp and seaweed. In the following text, we will just use the ones that are easy to say, so I won't explain them.)

Li Shimin was curious and couldn't wait to check out the so-called night school.

The night school in Zhuangshang starts at 7:00 p.m. and lasts until 3:45 p.m., with a 15-minute break in between.

Those who are studious will consolidate their knowledge when they go back home before falling asleep.

The next day the teacher will test you on what you learned yesterday. It’s a monthly test. If you learn well, you can take on more important positions. The pressure on adults is also great!

Li Shimin suddenly felt that the adults living in the women's farm were not so happy.
