Li Shimin's will: Li Zhi, the throne belongs to your brother

One is that the mountains are high and the emperor is far away, and it is difficult to manage all by writing letters; the other is that all kinds of trivial matters have to be taken care of.

How can this be solved?

Li Tai thought for a long time, then suddenly remembered something, turned to Li Shimin and said, "I think there is a scientific way to solve these two matters."

"Oh? A scientific method, tell me quickly." Li Shimin's eyes lit up, and he couldn't stand the nonsense for a long time.

Li Tai thought for a while and suggested: "I think that some trivial matters, such as stealing chickens and dogs, and courtiers fighting each other, can be made into a book.

Chapter 117

Tang law, people's livelihood and other solutions can be demonstrated, and then handed over to local officials, as long as they are not too stupid to follow the above, it will make one party stable. "

It is now called a reference example, such as the famous outlaw Zhang San.

For example, Tang laws and political affairs can be handled with reference to this example.

This will not only improve efficiency, but also improve the standards of local officials in handling political affairs.

Li Shimin thought about it after listening, and there are advantages and disadvantages to this.

"It's a good idea, but it's easy to deceive the upper and lower in that place, and their strength is easier to grow, so what should we do at that time?"

The method of handling political affairs is made into a reference book and distributed to local governments, which means proper decentralization.

Appropriate decentralization, coupled with too far away, will cause many problems such as breeding corruption, deceiving superiors and inferiors, and running rampant in the countryside.

Monitoring, monitoring, and processing methods are subject to change.

Thinking of this, Li Tai said slowly: "In mathematics, there is a subject called statistics."

"Mathematics? Statistics?" Li Shimin felt confused: "I seem to have seen... what kind of knowledge is this?"

You, Li Er, must have seen such an awkward explanation, and you definitely chose to pass it by.

However, this thing can be explained very vividly.

"Come here, bring a go." Li Tai said to the door.

Soon, the eunuch brought over the Go board and two boxes of chess pieces.

"Father, please take a look. My son uses Go to explain statistics in simple terms."

Li Tai wrote on the scale of the chessboard with a brush and explained again and again.

"There are many graphs in statistics, and what Erchen is going to use now is a line graph, which can be demonstrated with a chessboard.

Please look, father, the chessboard is divided into horizontal and vertical, interlaced to form squares of the same size.

Write the year on the horizontal box of the minister, which is the year of Wude and the second year of Zhenguan...

And write the population in the vertical direction, this represents 300 million households, this is 350 million households..."

After marking, Li Tai picked up the chess pieces and said to Li Shimin: "There were more than 200 million households in the Wude period, and the chess pieces should be placed in this square... In the early years of Zhenguan, there were 300 million households..."

Li Tai placed the chess pieces on the grid while chanting.

As more chess pieces are placed, a curve composed of chess pieces appears on the board.

Li Shimin's frowning brows relaxed, and his eyes gradually lit up: "This is really interesting."

Finally, in the 14th year of Zhenguan, Li Tai put down his chess pieces, because the population of this year has not been counted yet.

"Father thinks, according to the trend of Zhenguan in 14, what is the approximate population?" Li Tai asked holding a chess piece.

"This..." Hearing Li Tai's question, Li Shimin's expression gradually became astonished, and the hand stroking his beard gradually stopped.

Li Shimin didn't speak between Li Tai and Li Shimin, so he explained patiently.

"According to these trends, this year is not a year of major disasters, and there will not be too many wars. This year's population should be 460 million households."

After speaking, Li Tai put a white chess piece in the landing point.

"Could this be predicting the future!?" Li Shimin took a sharp breath when he saw Li Tai's fall, and couldn't add any more shock.

Li Tai was very speechless: "Statistics is a comprehensive science that infers the nature of the measured object and even predicts the future of the object through means of searching, sorting, analyzing, and describing data.

However, that doesn't mean it's necessarily true. "

As he spoke, he pointed his finger at the early years of Zhenguan and said, "Father, please see that in the early years of Zhenguan, there were three years of severe drought, famine, and plague... the population declined rapidly.

This line chart can only predict, but it may not become a reality, but it can refer to many things. "

"Just being able to predict is already very remarkable, so can statistics be used to count the fate of the country?" Li Shimin asked eagerly.

"Of course, the so-called national fortune can be roughly divided into the number of people, the number of fertile land, the number of soldiers and horses, the amount of money in the treasury, the number of bandits, and the number of refugees...

If you draw all these writings, you can clearly see the rise and fall of the country's operation."

Li Shimin's eyes widened when he heard this, and his beard stroking hand shook suddenly, pulling off a few beards.

Whether the national destiny is prosperous or the national destiny is declining, the national destiny has always been a very illusory thing.

But today, it was actually drawn with mathematics, and it can also infer the direction of the country's destiny... This simply overturned his imagination.

Li Shimin, who had pulled off his beard, grinned his teeth in pain, but fixed his eyes firmly and said: "Statistics...statistics, it really counts the national fortune."

"That's right, statistics count the fortune of the country and illuminate the future of the country." Li Tai nodded and said.

"Good! One that illuminates the future of the country, can show the rise and fall of the country's destiny, can know the pros and cons of national policies, and can know the capabilities of officials... This is really... Really."

Li Shimin was so excited that he didn't know what words to use to praise statistics. This thing is really good.

Before there was no statistics, the fate of the country was very illusory and empty. If you want to know the rise and fall, you need to rely on the advice of the officials, go out to the palace for investigation and private visits, and other methods.

In the local area, there are also methods such as evaluating officials on inspections to judge an official's performance.

Even the pros and cons of national policies are reported by people.

This is easily affected by the emperor's personal emotions, such as someone slandering, someone deliberately arranging....

In this way, the prosperity of the country and the quality of officials are all very false.

But with statistics it is different.

The ups and downs of local population, fertile land, taxation and other data all show the ability and performance of local officials.

And the summary of the population, fertile land taxation and other data of all places, shows the national fortune of the entire Tang Dynasty.

Although the data is also falsified, it is easier to find out that the data is falsified, such as whether the amount of autumn tax is correct or not, and the proportion allocated to each household.

As for the national policy, you only need to look at the population tax and other data to compare before and after to know the pros and cons.

In feudal dynasties, governing the country was like driving a chariot through a fog.

It is difficult to tell whether the front of the carriage is a steep cliff or a broad avenue.

And statistics is like a lantern, although it cannot 100% predict and decide the way ahead.

But it can illuminate the cliff ahead and the few open roads ahead.

It is true that it has illuminated the future of the country!

"It's really the eternal lamp of the country." Li Shimin said excitedly, and ran outside.

"The emperor is waiting, I'm going to call for someone now. I want all the important officials to experience the profound knowledge of statistics."

"Father, wait a minute. Father is only a superficial knowledge. What's more, is father really going to hand over statistics to important ministers?"

Li Tai frowned, why did he think about dressing up before he learned it?

"Shallow?" Li Shimin stopped in response, raised his eyebrows and turned his head and said, "I think I already know it."

Li Tai was speechless, now there are line charts, bar charts, pie charts... a lot of things, how could he explain clearly in a few words.

"As for handing it over to the important minister, I think it is necessary for me."

"Why?" Li Tai asked a little puzzled.

Chapter 118 Teaching Statistics

Li Shimin replied with a smile in his eyes.

"There are dozens of roads in the Tang Dynasty and hundreds of counties and counties. If you want to know the talents of each official, you need a lot of people to collect data."

Li Tai nodded after listening.

To apply this statistics, the first step is to collect data. Without data, nothing can go on, so this requires a lot of manpower and officials.

For now, teaching statistics is of no harm to Datang.

"Secondly, I want this world to return to my heart!"

"The world returns to its heart?" Li Tai frowned very puzzled, looking at Li Shimin's half-smile eyes, his eyes widened, could it be that...

Seeing Li Tai's shocked eyes, Li Shimin turned his head and ordered to the eunuch outside the door: "Propagate my will, summon important ministers, and discuss important matters!"

"Yes." The eunuch hurriedly left.

Li Shimin turned his head to Li Tai and said solemnly: "The emperor also made some preparations, and he will not go back to the East Palace in the next few days, and first teach statistics to me and the ministers."

"Yes!" Li Tai's face twitched a little, and he just didn't have to go back to church for a few days... until church.

"Go to the side hall, and take this "Mathematics" as long as you teach statistics." Li Shimin found the "Mathematics" book that Li Tai handed over from the imperial study.

"Yes." Li Tai took it speechlessly, and followed behind Li Shimin.

The two came to the spacious side hall.

They used to teach pinyin dictionaries here, but now many eunuchs are placing chessboards, chess pieces, pens, inks, papers and inkstones on tables and chairs.

In the end, I found a large chessboard from nowhere and hung it on the wall. The chess pieces are made of magnets, which can be attracted to the chessboard.

Seeing this, Li Shimin nodded with satisfaction and said.

"Today is not the day of the court meeting, and it is not convenient to place tables and chairs in the hall. Now we can only let the important ministers learn it temporarily, and then the important ministers will discuss how to implement it. All officials should learn."

"As it should be."

······

As time passed, more and more important ministers hurried over.

They thought something serious had happened, but when they saw Li Shimin's face became even more nervous, they hurriedly saluted.

"I pay my respects to Your Majesty and the Crown Prince."

"No courtesy, take your seat." Li Shimin raised his head and gestured.

But when they finished saluting and turned around to find their own seats, they looked confused.

"Put this on the chessboard, is it calling me to wait for a game?"

"If you are playing chess, can you still use pen and ink?"

"Could it be that you want me to write the chess record??"

Just when everyone looked at each other and made random guesses.

I don't know how long it took, but everyone finally arrived.

Li Shimin looked around, got up with a serious face, and all the officials stood up in unison, staring at Li Shimin, knowing in their hearts that the topic was about to begin.

Under the gaze of all the ministers, Li Shimin spoke cautiously.

"Oh, today I saw a subject in mathematics called statistics. I didn't see its meaning at first glance, but I couldn't extricate myself when I looked at it again."

After hearing this, some of the ministers frowned, some were suspicious, and some even had doubts, and kept slandering in their hearts.

Have new knowledge?

What knowledge can make you unable to extricate yourself?

Is this the same as a pinyin dictionary?

The ministers exchanged glances, with a trace of expectation on their faces.

"This time, the purpose of convening all the lovers is to do this, I hope the lovers will listen carefully and think carefully.

This knowledge can map the fate of the country, illuminate the future of the country, map the development of the region, and distinguish the talents of hundreds of officials. "

All the ministers heard three big greetings slowly appearing in their heads, with confusion in their eyes.
