Chapter 663: Good Timing for New Measurement Method

Chapter 664 The timing is right for a new measurement method (second update)

"Get the form, one form per person, and an abacus, and take them to the court to measure the land area."

In Li's village, Li Yi distributed things to 220 students.

Long tape measure, short tape measure, abacus, table book, pen, and square root table from one to one hundred.

"Remember the area formula of a circle and the three oblique square method. Don't use the area of ​​a sphere with a diameter times a sphere. Didn't our Zu Chongzhi give 3.1415926? Calculate according to 3.14."

Li Yi continued to say that the current formula for calculating the area of ​​a circle is the square of the diameter multiplied by three, and then divided by four.

If the diameter is eight, the square is sixty-four, multiplied by three to get 192, and divided by four to get 48.

According to the formula for calculating the area of ​​a circle, the radius is four, the square is sixteen, multiplied by pi 3.14, and the number obtained is fifty point two four...

When we get to the land, we encounter a triangular land that is not regular. We first measure the large piece that can be measured with steps, and estimate the remaining part.

Li Yi gave the method of three oblique squares. Knowing the three sides of a triangle, you can calculate the area of ​​a triangle.

When measuring, do not use steps, but use a tape measure. Agree on how many feet one step equals, and both sides convert.

Two hundred and twenty officials have work to do. Twenty are responsible for the land around Chang'an City, and the rest are ten people in each county.

They are responsible for teaching and statistics, and supervision by the way. There are a lot of tape measures, pulled by a cart.

They are serious officials. If anyone dares to cheat, they can be impeached by recording it in a small notebook.

The officials set out, shouldering the heavy responsibility of measuring the land.

Jingzhao Prefecture was in chaos, and the court ordered to re-measure the land. There was news that the rent would be calculated according to mu in the future.

Those who annexed land through various means were dumbfounded. How could it be possible? It can't be possible!

If the rent is calculated according to mu, their family will have to pay a lot more rent every year.

The people who were actually granted less land and the people who sold the permanent land were happy. If they recalculated, they could pay less rent.

The taxes and taxes were also cancelled, and the family could finally live a better life.

The officials of the big families in the court wrote back to tell their families about the situation in Jingzhao Prefecture, and they would definitely adopt the same method in the whole Tang Dynasty in the future.

If you don't want to pay more rent every year, think of a solution quickly.

The court was surprisingly calm, no one impeached, and the Imperial Censor and a Deputy Imperial Censor were still in prison.

Your Majesty wants to implement a new policy in Jingzhao Prefecture. Opposition is useless and will implicate yourself.

Many rich families cried loudly, feeling that the trial method was cutting their flesh.

"In this way, there will be no worries about land annexation. People who have no land will not pay any taxes and taxes, and they can just find a job to make money."

At noon in Tianshang Renjian, Yao Chong and others had dinner again, and Lu Huaishen had a smile on his face.

Zhang said he was using a pen and a ruler to calculate: "The hypotenuse is three, the leg is four, and the chord is five. Two right triangles together make a rectangle.

One side is three, one side is four, and the area is twelve. Divide it into two triangles, one is six.

Then calculate according to the formula.

The perimeter is three plus four plus five, twelve, divided by two, six, six minus three, multiplied by six minus five, multiplied by six minus four, six, then multiplied by that six, thirty-six.

The square root of thirty-six, six times six times thirty-six, equals six, that's right."

He chose the stupid method to verify the correctness of the formula and found that the data was correct.

"In this way, it will be convenient to calculate the area of ​​a triangular land in the future. The area of ​​a circle, Zu Chongzhi, three and three point one four, there is a big difference."

Wei Zhigu was looking at the formula for the area of ​​a circle, which was different from the method of diameter one perimeter three that has been used now, and it was more accurate.

Bi Gou was worried: "I am worried that if the local government knows that Jingzhao Prefecture has a land rent distribution system, there will be chaos, and the big families may start a rebellion."

"Rebellion? What rebellion? Rumors? Are they getting the news faster than the imperial court sending fast horses to various prefectures?"

Song Jing is not afraid, the imperial court has soldiers, and the imperial court's documents are spread through the post station.

Tell the local government offices to post the Jingzhao Prefecture's land survey and collect rent according to the number of acres.

The people without land will hope that the court will quickly implement the decree in the local area.

No matter how powerful the local forces are, they cannot incite the people. With their own limited manpower, the imperial court's soldiers are just decorations.

When he thought of the current surrounding situation, he shook his head: "Did Li Yi take advantage of the Turkic civil strife, the difficulty of Khitan to rely on, and the defeat of Tubo to come up with this method?"

He suspected that it was too coincidental, why didn't he mention it earlier?

"Next year, my Ministry of Revenue will collect more rent from Jingzhao Prefecture alone. There will be less money for transfer, but more money for merchants."

Bi Gou returned to his happy look, and he hoped that the Tang Dynasty would start as soon as possible.

This year in Jingzhao Prefecture, next year, the land can be surveyed in most places in the Tang Dynasty, and the tax collection work can be promoted by the way.

Yao Chong looked at the people walking in the sun outside the window, wiping sweat: "One tax, one rent per mu, all target rich households and wealthy merchants."

"The dictionary will be published next month, and the newspaper staff will be trained before the end of the year, targeting other families."

Zhang said that he looked at Lu Huaishen, who was from a big family.

Lu Huaishen looked out the window together: "What kind of family is mine? It's just a side branch."

"If everything is promoted well, the prosperity of the Tang Dynasty will really come. In the past two years, Chang'an has changed too much."

Yao Chong, who was still looking at the people below, showed expectations in his eyes.

He looked for a long time, but didn't see a pedestrian wearing tattered clothes.

It means that everyone has money, at least money to buy clothes.

If you can buy clothes, of course there will be no problem with eating.

"Song De." Lu Huaishen saw an acquaintance.

Song De drove a cart with many watermelons on it, and walked over under the protection of a group of Yulin flying cavalry.

"He went to the East and West Markets to sell watermelons?" Bi Gou leaned down.

"The watermelons in Lijiazhuang are not enough for their own consumption, so why would they sell them? He sent them to Beitianfang.

Lijiazhuang sent things to Beitianfang every day, usually leftovers from Zhangjia Village.

It's been hot recently, and it doesn't rain. I sweat when I sit. Let's eat."

Zhang Shuo followed and looked at it, and ignored it.

Before they finished eating, Song De appeared again, and the watermelons on the cart disappeared, replaced by a mess of things.

"He loaded his cart with old clothes? And leather clothes, where did he get them from? To exchange them with watermelons?" Lu Huaishen was puzzled again.

"He went to the pawnshop, and the clothes were dead and not redeemed. Why did Li Yi want old clothes?" Yao Chong raised his eyebrows.

He would not pay much attention to others going to the pawnshop to buy things.

Li Yi bought several cars at once, how could he not think about it.

"I'll go to Li's manor to have a look in the evening. UU Reading www.uuｋanshu.net" Bi Gou looked at Yao Chong proudly, Yao Chong couldn't go now.

"I'll go too." Song Jing decided to go with Bi Gou.

"By the way, ask him if there are any big moves. Don't throw them out all of a sudden. I don't know who the prime minister is."

Zhang Shuo, who also couldn't go to Li's manor, made a request.

Everyone nodded, yes, ask, Li Yi has been honest for a while, he won't be crazy now.

After dinner, everyone went out, there was no coolness in Tianshang Renjian, the heat wave hit us.

"The merchants who stocked ice last year have made a lot of money this year. Is there any good way to cool down? Go to Li's manor to ask in the evening."

Bi Gou is old and can't stand this kind of weather.
