Chapter 82 Wujin County

Zhu Jianjun smiled and said: "The six arts of the gentleman, Lone still has some research. ”

Nonsense, how Zhu Qizhen didn't know the importance of mathematics.

Therefore, Zhu Jianjun's mathematics was taught by the people of Qin Tianjian, and even Zhu Qizhen would teach him personally sometimes.

There is not much of a high level, but there is still a level in middle and high school.

Of course, Zhu Qizhen himself is not a good teacher, and after so many years, he has long returned the books he read when he was a teenager to the teacher.

The things he handed over to Zhu Jianjun were all basic and simple.

Zhu Qizhen doesn't care that Zhu Jianjun becomes a mathematician, but he hopes that Zhu Jianjun has the most basic mathematical thinking, such as some data reported below, and he can analyze it.

You can't be at a loss and you can't see anything.

But even so, Zhu Jianjun's mathematical ability is not very good in this era, and the real mathematicians have all been brought to Qin Tianjian by Zhu Qizhen, and are calculating the orbits of the sun and the moon, and some people have even gone to various places to measure the four seas.

It's just that compared to the major events being implemented by the imperial court, this matter of measuring the four seas cannot be said to have been fought, and the cost is not much, and it is impossible for people who are not specialized to notice it.

In addition to these math and astronomy bosses, Zhu Jianjun's mathematical ability is not first-class among the Ming officials, but it is enough.

Kou Shen said: "In that case. His Royal Highness is also very familiar with these processes now, and the minister is bold, how about asking His Highness to lead a team to Qingzhang Land in Wujin County? ”

Zhu Jianjun said: "I have been looking forward to it for a long time. ”

Kou Shen had already sorted out the situation in Wujin County, and he also knew that there were no major problems in Wujin County.

First of all, there is no big clan in Wujin County, although some families have a large population, but there are no high-ranking officials and dignitaries, and they can't be called big clans. The only one who has some climate, but also a more honest one.

It won't make things difficult for the prince.

As for the Wujin County Commander, he is a good man.

It is one of the counties in the south of the Yangtze River with relatively little resistance.

After Kou Shen arranged Zhu Jianjun, he specially told Jinyi Wei to protect the prince's safety, and the prince did not go down by himself, but with his entourage, and more than 100 people pretended to be officials.

These guards of the Qianqing Palace can't talk about both civil and military affairs, but they are temporarily recruited and transferred to write and calculate, but there is no problem at all. After all, all of them were born in martial arts.

In addition, Cao Nai specially transferred an army from Nanjing nearby.

Even if something happens, he will come to Zhu Jianjun's side within an hour or two. Even Kou Shen also spread rumors that the crown prince was the grandson of a certain bigwig in the court.

It was also to cover up the prince's anomaly.

After all, the situation between the prince and his surroundings can be seen by anyone with a discerning eye.

This is also a true and false plan. After all this was arranged, Kou Shen focused on the accounts in his hands. This marked place name is the problem of Jiangnan measurement.

If Kou Shen wants to fool the past, he is just raising his hand. It's just that he doesn't want to.

After all, he didn't want his lifelong reputation to go down the drain, and he didn't want to live up to the emperor's expectations.

After all, why did the emperor turn out this old minister who had already been Zhishi, Kou Shen also understood.

If you offend these people in Jiangnan, you will suffer greatly, but if you disappoint the emperor, this will be a big trouble.

"Let's go." Kou Shen secretly said in his heart: "Do the last thing for Your Majesty." ”

Kou Shen and some people in Jiangnan secretly can't see the fight, and the prince is not too clear.

First, Kou Shen hid from the prince, he didn't want to make things bigger, and the same was true for the Jiangnan side.

They just wanted Kou Shen to slow down, and they didn't want to do anything else, so naturally they wished that the prince didn't know anything.

This kind of undercurrent, as long as they erupt, outsiders will understand.

But the prince took his own guard, abandoned his horse and took a boat, and went to Wujin County, Changzhou.

Wujin County is Changzhou Attached Guo County.

After arriving in Changzhou, the governor of Changzhou did not receive them, but directly asked the county order to receive them.

As mentioned before, the county magistrate is a good old man. After the prince arrived at the county office, he exchanged a few words of greeting, and asked people to take out the yellow book of the dynasty. The prince began to work.

First of all, starting from the fish scale atlas, the land of Wujin County was divided into pieces respectively, and they began to be cleared, and compared with each other in the yellow book. Once the land has been determined, the locals will be gathered to identify the owners of the land and mark them on the scale atlas.

It's easy to say, but it's very cumbersome.

After the beginning, the prince understood why Kou Shen said that he was good at mathematics.

Because measuring land is essentially a mathematical problem.

Nowadays, the commonly used method is the opening method.

Of course, this method is not to open the square, but to convert the irregular land into a standard square by various means to calculate the land area.

This is actually a junior high school math problem.

It's not too difficult to say, but it's very tedious.

After all, mathematics in reality will not give you a whole number, you must know that many places in the Ming Dynasty have seven or eight decimal places after the decimal point, which shows the complexity of these specific accounts.

Zhu Jianjun was calculating with his guards, and these guards couldn't help at this point? After all, mathematics in martial arts does not teach geometry problems at all. While muttering in his heart: "After I go back, I must suggest that my father round everything except two decimal places." ”

But he muttered in his heart, but there was nothing he could do, at least now he could only do it in this way.

In fact, although these tasks are tedious, Zhu Jianjun is competent.

And Zhu Jianjun understands very well that his father sent him over, not to let him do these things, but to let him pay attention to the people's livelihood.

So when things are on the right track, Zhang Mao and others can replace him, or after Zhu Jianjun's freshness, they will pay attention to the local people.

First of all, the local people are afraid of officials.

Although Zhu Jianjun came out as an official, in order to make it convenient for Zhu Jianjun to do things, Kou Shen gave him a seven-grade official position.

This seven-grade official position, in Zhu Jianjun's eyes, is just a small official like a sesame mung bean, but for the local people, it is a very big official position.

It's as big as the county magistrate.

Enough to make them tremble.

Zhu Jianjun also got acquainted with them for a few days.

Only then did I understand what the situation on the ground was like.

First of all, most villages are actually composed of small families, that is, parents, sons, daughters-in-law, and a child.

Therefore, many people see the door of the mansion on TV, and the situation of how many people live in a family, but it is not common, and the life of most people is actually similar to the family structure of later generations.

If there are many people in the family, the older generation will take the initiative to divide the family.

In many cases, it is impossible to raise.

Because in the village, the means of production are fixed, and the output is also fixed, and in the years when the world has just been peaceful, there is still enough wasteland to be cultivated.

But time has passed, and there is no wasteland for a long time.

Therefore, there are many people in the village who have left their hometowns to beg for a living outside, to be tenants, to be merchants, to work hard in the city, in various ways.

Ordinary people are incapable of bringing people from their families together.

Separation became inevitable.

The high infant mortality rate also makes it difficult for ordinary people to have multiple children, and most of them are just raising one or two sons.

There is even a tradition of drowning female babies in order to raise a son.

It can only be a tragedy.

The male ploughing and female weaving is an accurate description of the production of this era, especially this area is close to Taihu Lake, which is a traditional silk production area, and silkworm raising is a craft handed down by ancestors for hundreds of years.

Therefore, every year the grain is harvested, and raising silkworms and selling cocoons is the harvest. Together, these two harvests are still tight for the people, but they have exceeded most areas of the Ming Dynasty.

The silkworm cocoons and silk produced by these countryside continue to flow into Suzhou, supporting tens of thousands of looms in Suzhou, and also supporting Suzhou, a big city with more than two capitals in the Ming Dynasty.

Jiangnan handicraft industry is not only silk weaving, there are many things, Jiangnan wealth is the world, although there is a fertile land in Jiangnan, but more is the support of these handicrafts.
