I opened a tavern in Datang/Datang: My peerless talent was exposed

Chapter 63 The Magic of Mathematics

Although Zhang Nuo has never been an official and has no deep understanding of mathematics, the Internet information and programs of later generations are so developed.

As long as you want to know, there is nothing you don't know, and all the great gods are talking to each other on the Internet.

If there is a news hotspot, the media, experts, and commentators flock to it, analyzing, decomposing, forecasting, assuming, and focusing on it... Anyway, how do you appear to be professional.

Although it is all for grabbing hot spots, it has to be said that this has instilled a lot of strange knowledge in people.

Therefore, this is the reason why Zhang Nuo can tell so many things to people even though all the cheats have not been credited to the account.

After all, in future generations, as long as you like to surf the Internet, you can always share some knowledge that has nothing to do with your work and life.

No matter how old Li is, Zhang Nuo was just talking about hi today. He started talking because he wanted to do business in teaching supplementary materials, but he couldn't bear to talk after chatting.

"Old Li, you have to know that although mathematics is not as gorgeous and beautiful as poetry, it is a subject that can truly reflect the essence of things."

"Such as the two of us, don't we have to keep accounts, and we have to check the money through the accounts every month, every quarter and at the end of the year?"

"A good businessman can see the problems of his own business at a glance from the ledger, and a good official should see the local problems at a glance from the figures."

Li Shimin stared blankly at the eloquent young man in front of him, wondering if he had gone to the wrong place, the place he came to was not a restaurant for drinking and eating, but a lecture on Confucianism in a certain Imperial College?

This is not the first time he has been shocked by shopkeeper Xiao Zhang. From the poems, he can see the other party's literary talents, and from talking about the past and the present, he can see the other party's understanding of national affairs, but now the other party has no clue about how to manage the place. There is a corresponding way.

It scares him a little bit!

This is no longer an ordinary pillar of talent, this is the foundation of the country, the ability of the prime minister just now possessed!

The so-called "know the whole leopard at a glance" means that through the figures and descriptions on the report, one can know the specific local problems and propose solutions without leaving home.

Aren't these jobs the prime minister's job?

Moreover, he is not just an ordinary prime minister, he has to be a heavy prime minister who can leave his name in history!

Li Shimin felt extremely happy at this time, this is God's favor for him, allowing him to meet shopkeeper Xiao Zhang in the market, and let him discover the magic of shopkeeper Xiao Zhang.

Shopkeeper Xiao Zhang can still work for 50 years now, which can completely accompany him to travel across the world and Kyushu.

He is simply the best Wang Zuozhi!

Moreover, this is still the result of the short time of contact, and the two sides just chatted!

Li Shimin couldn't imagine how amazing it would be if shopkeeper Xiao Zhang was really allowed to enter the court?

However, seeing the other party's appearance in green cloth and sackcloth, he was a little hesitant. Such a commoner acquaintance, now that he has become the emperor, is really rare.

Therefore, we still have to wait until Shopkeeper Zhang makes a few more contributions, and think of a way to get Shopkeeper Zhang to the court. The scene where the monarch and his ministers meet must be very interesting.

Seeing that Lao Li started to lose his mind while listening to it, Zhang Nuo was a little unhappy. Why, my brother is talking about university questions. Later generations finally read some columns. I really can't remember it.

You, a businessman, are not willing to listen to such a great knowledge?

I'm still not willing to talk about it, young master!

The baby is angry and not happy!

Li Shimin pondered there for a long time, suddenly felt that there was no sound on the other side, and looked up, dumbfounded.

Shopkeeper Xiao Zhang is squatting on a chair at the moment, propping his head in one hand and holding chopsticks in the other, throwing some food into his mouth from time to time.

This is a typical shape of a street rogue!

But Li Shimin had not dealt with Xiao Zhang's shopkeeper for a day or two, and he knew his temper somewhat, which was typically because he was distracted just now and got angry.

Li Shimin didn't mean to be angry at all, but he felt close.

This is why he was so reckless when he was treated as a friend. Back then, when he was not the emperor, or even the king of Qin, he was laughing, cursing, and fighting with many friends like this.

Therefore, Li Shimin flattered Zhang Nuo incessantly. He used the skill of the servant who flattered him back then, and made a toast for half a pot of wine, and finally made Zhang Nuo happy.

If there were any other courtiers in the court today, I am afraid that the eyeballs would drop off the ground. His Majesty, who is usually majestic and solemn, actually bowed his head and bowed in front of a young man today, bowing his hands and saluting to make people happy?

This is probably an anecdote in the world!

Zhang Nuo didn't think he was so awesome, he really regarded Lao Li as a friend, not to mention the conversation, and now he is doing business together.

Especially after the partnership, only a head of security was sent over to look over the accounts, and deal with the troubles by the way, leaving the rest alone.

This is simply the most trustful expression between partners, isn't that enough brothers?

So in front of Lao Li, Zhang Nuo really didn't hide anything, he laughed when he was happy, and scolded when he was unhappy, living a very real life.

After playing and laughing, Zhang Nuo finally sat down and continued his narration.

"Lao Li, since you are still interested, let's continue talking!"

"I'm talking about counting. The reason why it is important is because as long as the accuracy of the numbers can be guaranteed, many problems can be found from the numbers alone."

"Let me give you an example. In the third year of Wude in a certain county, there were [-] households with a population of more than [-]. In the ninth year of Wude, there were still almost [-] households with a population of less than [-]. What does this figure represent?"

Hearing the question from shopkeeper Xiao Zhang, Li Shimin became very serious. He didn't think it was just a small talk in the market, but it was obviously a scene where the emperor and ministers of the Liangyi Palace played against each other and discussed state affairs.

Because there are actually a lot of such examples in the data of the Ministry of Household Affairs, all of which have not grown in population for several years.

The population at this time represented tax revenue, combat power and even national power, so he couldn't help but relax a bit. As the supreme being in the world, how could he play games?

So Li Shimin straightened up his waist for a rare moment, began to think with a serious face, and unconsciously began tapping his knuckles on the table slowly and rhythmically.

He can't ask this question indiscriminately, he has to think about his own answer, and he also hopes to listen to shopkeeper Xiao Zhang's high-level discussion today.

Chapter 64 Li Shimin's Education

Li Shimin pondered for half a cup of tea before seriously speaking,

"Brother, we can't talk nonsense about the court, I'm just talking about my guess."

Li Shimin became serious, his words were watertight, and he made his attitude clear first, he was just guessing, so he couldn't be sure.

This is his habit, when he can't make a decision when he is right, he doesn't say anything to death.

"In six years, the population of a county has only increased by 1000. First check whether the local area suffers from drought and famine caused by floods, and then check whether there are excessive and miscellaneous taxes in the local area."

Zhang Nuo nodded noncommittally, then said slowly,

"Old Li, thanks to the fact that you are not an emperor, nor an important minister in the court, otherwise, my Tang Dynasty would have been ruined by you!"

Li Shimin immediately became unhappy, what's wrong?

Why can't I, Li Shimin, be the emperor? It has been less than half a year since I ascended the throne. Not to mention anything else, there are Turkic riots outside, and old ministers inside are not peaceful. If it weren't for his majesty Li Shimin, Emperor Li Shimin, he is so wise and mighty. What a mess.

But Zhang Nuo didn't give him a chance to refute at all, and raised his hand to stop him from speaking.

"Old Li, don't be convinced. You are a typical businessman, and you are still different from a well-educated person like me. You only saw that the population increased by less than 1000 in six years, but you didn't notice the land of a county. There has been no increase in the account for six years."

"Businessmen, they always pay the most attention to these numbers that increase and decrease, but ignore the most important things inside!"

"Old Li, you have to know that my court pays taxes based on households, and not adding households means that tax revenue will not increase. Therefore, if the court officials and His Majesty see this number, they must pay attention to the number of households immediately. rather than population."

"That's what I said, you can only be a businessman and not an official!"

Li Shimin patted his forehead annoyed, really, he didn't notice another important number in it, the number of households didn't increase, it was really inappropriate.

Zhang Nuo didn't care about Lao Li's remorse, and continued with a smile,

"The number of households has not increased in six years, so there is only one problem, that is, there are too few strong men! Without strong men, it is impossible to start a family and start a business, and naturally it is impossible to divide the family, so the number of households cannot be increased."

"Then is there banditry in the local area? Is it because the imperial court has recruited too many government soldiers in the local area, and they have been stationed and fought in other places for a long time and have not yet returned home?"

Li Shimin suddenly realized, yes, there is indeed such a possibility, now the left and right military guards have to practice, and before that there were constant conquests, some veterans did not go home for several years.

But this conversation made Li Shimin even more interested. He read the memorial before, and [-]% of the [-]% were words.

According to the different writing styles of the courtiers, some of them are extravagantly written, some are written concisely, but very few of them use numbers to directly explain the problem.

Now that the shopkeeper Xiao Zhang said this, he discovered that it turns out that using numbers to explain the problem is the most intuitive existence.

Zhang Nuo didn't know that he was simply bragging, which made the current emperor want to change the whole official atmosphere. If he knew, he would be very happy.

Why, because what is good at the top is effective at the bottom, as long as the emperor likes it, then the important ministers must also like it, and then it is suppressed level by level, and you have to like it if you don’t like it.

So so many people have to study mathematics hard, so can I sell basic reference books on mathematics, and then earn money and get soft?

Li Shimin was really interested in this right now, so he hurriedly approached Zhang Nuo with a shy face and said,

"Brother, come and continue to talk to my brother, what is the use of this calculation in the court?"

"Brother is a businessman. I can't be an official in this life. I can only listen to what you have to say. You can't hide anything from my brother!"

Li Shimin was also a little embarrassed by his words in his heart. This was to dig out some good things from the shopkeeper Xiao Zhang, and he was completely shameless.

But he was right, he was the emperor, and he would never be an official in his life.

Zhang Nuo doesn't care, it's just chatting anyway,

"Old Li, you really have to listen to me. The business journey is the most important thing for calculation. Although the court is important, it is [-] miles away from us!"

"But if you want to hear it, I will continue to tell you!"

Zhang Nuo poured himself another glass of wine with a smile, and then took two mouthfuls of food slowly before continuing with Lao Li's eager expression.

"What the county magistrate needs to learn is statistics, how to fully mobilize manpower, and report the situation under his own rule!"

"What court officials need to learn is statistical analysis. They have to analyze the real situation in the local area from the data submitted by each county, and then summarize it into a report and submit it to His Majesty's desk."

"In the end, His Majesty will be able to hold the report in one hand and the data in the other, and refer to each other!"

"Let me give you another example. For example, how many newborns are born in the local area every year, and what percentage of the total population is there? What is the premature death rate of newborns?"

"These two figures, one can reflect whether the local area is rich, after all, if the family has no food, they dare not have children, and the other can indicate whether the local area is short of medical care or medicine."

"So, adding this to my previous example, even if it's just two simple things, can we see a lot of things?"

"This is what I said. The reason why the imperial examination must include arithmetic! Only when you know arithmetic can you make reasonable statistics and report data, and only if you know arithmetic can you analyze and summarize data reasonably."

"You can't just submit an article full of colorful flowers all year round. It seems to say a lot, boasting that you will never close your house at night or pick up lost things."

"But in fact, numbers are the most real. As long as the authenticity of numbers is guaranteed, any problem can be reflected!"

Li Shimin was delighted to hear that, that's right, that's it, the report you handed in at the end of the year said it was like a flower, but if the tax revenue is not good and the population does not increase, then there is definitely a problem.

He has already made up his mind, and he will start to arrange this matter slowly when he turns around.

Talking up to this point, in fact, we have talked enough for today. He came here at noon, and the sky is getting dark now. It seems that it is almost dusk.

Then he has to go too, there are other things to do when he returns to the palace.

However, seeing Zhang Nuo's sluggish look, Li Shimin turned his head and thought, this can't work, every time I went through this over and over again, I was educated by Xiao Zhang's shopkeeper, so I have to find a way to teach it back.

This little shopkeeper seems to be unable to teach knowledge, and it is difficult to imitate him, but is he also excellent in other aspects?

Chapter 65 Give You a Bodyguard

After thinking about it for a while, Li Shimin slowed down his pace of leaving immediately.

He got up and went to shopkeeper Xiao Zhang, hooked his shoulder and said,

"Brother, I see that your body is quite strong, have you ever thought about practicing martial arts?"

When Zhang Nuo heard Lao Li say this, his eyes lit up immediately, and he said loudly,

"I want to, of course I want to, but I can't find a good teacher. Do you have such a talent, Lao Li? I'll pay for one! If it's someone who is really capable and willing to teach me seriously!"

Li Shimin smiled like an old fox who stole a chicken, and said thieves,

"Brother, I have prepared it for you a long time ago. My coachman Xingben was originally a good player in the Jianghu.

"However, my brother is getting old, so general martial arts are naturally okay, but it's not enough to learn advanced martial arts. After all, you're old, but you can do it!"

"Now that you are not as young as the weak crown, it is time for your body to be strong. With Xingben's teachings, maybe someday you will become a titan who can defeat ten thousand with one enemy?"

"Then brother, you are a unparalleled figure with both civil and military skills!"

"How about it, do you want Xingben to be the head of the nursing home for you for a year or so? With Xingben in the future, you will save yourself all the troubles in Chang'an City."

"Xingben knows too many people. He knows all the people my brother knows in the officialdom. You don't need to ask for small troubles, he will solve them for you. It's absolutely easy to use!"

Zhang Nuo looked at Lao Li's proud face, as if he was selling some peerless secret treasure, and he couldn't believe it.

He's just a coachman, even if he's the head of the guard, he's at most a captain of the bodyguard, and he has friendship with people in the officialdom?

The key is that Lao Li is still a big talker, what do you mean you don't need to speak up by yourself, if you don't solve it by then, won't you be responsible for it yourself?

Li Shimin saw Xiao Zhang's disbelieving expression on his face, and immediately became unhappy.
