People in Datang have been expelled from school

Chapter 1119 Matters of Tian Mu
In the past two years, the rich and powerful have encroached on the fields from time to time, that is, to check Jingyang, if you check other places, there may be twists and turns. The land issue in Datang is a tight rope.

Li Shimin looked down at the formula on the table and frowned, and of course he also wanted to check the land in the world.

However, since the former Sui Dynasty, there have always been cases of dignitaries encroaching on land.

Although the affairs of the DPRK and China are still relatively clear, the problem is still in front of us.

This is a lesion left over from past dynasties.

If you want to get rid of this lesion, you need to take strong medicine.

Li Shimin sighed and said, "Fang Xuanling, do you think I should do it?"

Fang Xuanling said in a low voice: "Your Majesty, the Tang Dynasty has not been established for a hundred years, and I think it is too late."

Li Shimin smiled wryly. For some reason, an idea suddenly flashed in his mind. Li Zheng must have a way.

With a long and exhausted sigh, Li Shimin said in a low voice, "It's getting late, you should go to bed earlier."

Fang Xuanling bowed and saluted, "I will take my leave."

Sitting alone in the Ganlu Hall, Li Shimin looked at the empty night outside the hall and remained silent.

At dawn, the Ministry of Household Affairs began to carry out nervous investigations of the fields.

With the formula given by Li Zhi, the speed of checking the account books of the fields is several times faster.

A group of officials from the household department could even draw inferences based on this formula, multiplying and dividing in just a few hours to complete Jingyang's half-year farm account book. Wei Zheng nodded in satisfaction as he watched the speed in front of him.

At the edge of the fields in Jingyang, Li Zhi also took several officials from the household department to measure the acres of the fields.

Li Zhi took out a roll of coil and said, "This coil is ten feet long in a cycle of ten colors, and you don't need to use such a short measuring ruler to measure it one by one."

The household official took the coil and said, "Is this thing accurate?"

Li Zhi said, "The error won't be too big."

In order to be cautious, the officials of the household department first measured the fields that had already been measured.

Indeed, as Li Zhi said, the thread of this coil has ten colors and the length of each color is one foot.

After confirming that it was correct, the officials of the household department began to measure with this coil.

Tie one end of the coil to a stake, pull the wire back, pull it to the other end of the field, and fix it with another stake.

The lines are straight and parallel to the ridge.

Just count the colors above to get the width of the field in acres.

Most of the fields in Jingyang are paddy fields.

It is also convenient to measure.

It depends on the officials of the Ministry of Household Affairs to calculate the area of ​​​​the field or use the cumbersome method of subtraction and addition.

Li Zhi shook his head and said: "You guys do the calculations like this, when will it be calculated? Has our household department always used such a stupid method to calculate?"

The officials of the household department looked at each other, smiled wryly and didn't know how to answer. In fact, the household department has always used this method to count the acres of land.

"I also ask His Royal Highness King Jin to enlighten me."

Li Zhi sighed and said: "I don't know how you usually do things for the father."

Listening to Li Zhi's scolding, the officials of the household department were unhappy. How old is His Royal Highness Prince Jin?He is only 14 years old this year, and he is not yet an adult.

While writing the formula, Li Zhi said: "In fact, there is a simpler method. First, the length and width of the field must be clear. Multiplying the two is the square area."

Square area?

A group of household bureaucrats were once again confused.

Li Zhi added: "There is a saying in the Nine Chapters of Mathematics that multiplication is called power. The formula for area has already been given to us by predecessors, and you officials in the Ministry of Households don't know this."

"My lack of talent and learning made His Royal Highness Jin laugh."

Li Zhi went on to say: "After we calculate the area, we need to calculate the number of acres of fields. According to the number of acres of fields in your household department, we should add three and then add three, square three, and then divide by the value of one mu, which is the number of acres of fields. According to fifteen acres One hectare of land, the field we measured just now, totals two hectares."

After Li Zhi finished speaking, several household officials stared at the formula and remained silent.

The officials of the household department still have some understanding of arithmetic.

On weekdays, it is not enough to calculate taxes and salaries.

It's just that Li Zhi's formula was a little stunned for a while. Such a complicated algorithm in ordinary times is much simpler after Li Zheng's formula.

Looking at himself, and then at Li Zheng, there was an inexplicable feeling that half his life had been wasted.

Li Zhi said: "If you have any questions, you can come to the academy to find me, or you can find other senior students. If you think about it, such a simple question should not be difficult for you."

The officials of the household department still smiled awkwardly.

Wei Zheng, who was resting at noon, came to the stables and saw Li Zheng sitting leisurely under the shade of a tree drinking tea.

Seeing Wei Zheng coming, Li Zheng said, "Duke Zheng is done with his work?"

Wei Zheng sat down at the side and said, "I checked your road repairs back then, but now I haven't found any clues."

Li Zheng said: "It is actually an advertising effect for us that Zheng Guogong checked our road construction. I hope Zheng Guogong will continue to investigate."

Wei Zheng said, "You think the old man helped you instead."

Poured a cup of tea for Wei Zheng, Li Zheng said with a smile: "I don't have much good tea before tomorrow, Zheng Guogong has a sip?"

Wei Zheng picked up the teacup and took a sip of hot tea, still looking at Li Zheng, "The old man doesn't sound right."

Li Zheng said: "Duke Zheng, do you know? How is your reputation outside?"

Wei Zheng sneered, "This old man never cared about his reputation."

Li Zheng said: "It doesn't matter whether you care about your reputation or not, but your reputation outside is that you are honest and upright, a loyal minister who dares to speak out, and you are a stubborn old man who doesn't care about oil and salt."

After hearing these words, Wei Zheng frowned.

Li Zheng said again: "I would like to thank Zheng Guogong even more. The counties and counties where we built the road were our resistance, but Zheng Guogong couldn't find any problems, but it made our road construction faster and unimpeded."

I was in a good mood at first, because I wanted to thank Li Zheng for his help because of the investigation of Tian Mu.

Now Wei Zheng has no mood to thank him at all.

Li Zheng drank a sip of hot tea comfortably and said, "The weather is very nice today, isn't it, Zheng Guogong."

Wei Zheng looked at Li Zheng and said, "Are you using this old man?"

Li Zheng said with emotion: "Zheng Guogong's words are wrong."

Wei Zheng said coldly, "Why not?"

Li Zheng shook his head and sighed: "First of all, Zheng Guogong also understands that road construction is beneficial to the country and the people, right?"

After thinking about it for a while, Wei Zheng said, "I think there are pros and cons to this old man. Large-scale conquest of people's strength is something that needs to be cautious. It is time for the Tang Dynasty to recuperate. It is really inappropriate for you to start large-scale construction at this time."

Li Zheng said: "I didn't force people to recruit labor, and I gave enough wages. All labor is voluntary."
