In the Sui and Tang dynasties, there were already official officials who drew maps, and Fang Lang of the Ministry of War.

This is a professional official who belongs to the government, and it has been passed down from generation to generation, and it also attaches great importance to maps.

However, they drew a map on a small scale.

That is, a map, which often represents a vast territory.

Maps were a specialized and noble job in feudal times, and required secrecy.

Large-scale maps are not absent, but most of them are archived in local government offices. It is estimated that when the magistrate first took office, he would look through it to understand the general situation of the jurisdiction.

In addition, it is to lead the troops to fight, for the need, the map to probe the map.

Of course, these large-scale maps will not be circulated, they are formed by the continuous collection of information by the generals who fought in various places, and since it is impossible for the general to go to the scene to guide, these maps have all kinds of tricks, just by the concepts in the minds of these generals or by the people who draw maps at will under his subordinates.

It can be said that one person has a set of methods.

At this time, fighting a war is not the job of an expert.

Of course, if you can survive the battlefield, you will gain some experience and can be considered half an expert.

Basically, the drawing of maps is officially owned, and ordinary people rarely touch this kind of thing.

Even businesses will collect geographic information and draw it into a map, but their set may be something that others can't understand.

A hundred businesses, a hundred sets of map methods, maybe only the appearance of a river, everyone will be interested in the same ink line as a representative.

At this time, it is still difficult to control the thickness of the lines and use the thickness of the lines to represent different existences.

However, the location of the war is often important at a certain moment, and the map drawn by the transit because of the war is no longer important, and will eventually become a stored manuscript, and no one will redraw the information, which is equivalent to being in vain.

Fan Jingjing really wanted to take the careful girl out this time, but she knew that not only did she have to deal with a lot of fierce beasts in the wild, but more importantly, these mapping jobs sometimes had to climb up and down and bask in all kinds of sun.

Not some. People who have been trained will feel very hard about this kind of work.

Fan Jingjing still habitually thinks that women are delicate, and women who forget about the Tang Dynasty are actually no different from an ordinary man most of the time. The responsibilities on their shoulders are even heavier than those of men.

Men go to the battlefield, and life off the battlefield must be picked up by women.

Fan Jingjing doesn't really have any idea of drawing a map, but he knows what an ideal map looks like in the end.

Fan Jingjing didn't do anything special, she just found an area within the current range of the Fan family manor and drew a map of a small area, and did a test on the people in the Fan family manor.

The results of the test were far from satisfactory.

In Fan Jingjing's view, there is no reason why everyone can't learn such a specific thing.

But there are some people, and the sense of space is not good.

In this day and age, it seems to be especially serious.

But Fan Jingjing found that Liang Shu, who is particularly good at hunting, seems to have a good sense of space.

It's a pity that they joined late, and they haven't learned trigonometry yet.

At present, there is no one who has learned trigonometric functions. Even Li Liqian, who is the best in mathematics, has only learned fractions.

Fan Jingjing knew that this time to receive the territory given by the emperor, it was not necessary to draw too detailed a map, as long as the general range was drawn.

And in this block, she must find a way to leave a mark on the official, otherwise it will be reclaimed by others, which is unreasonable.

During this time, the people of Fan's Manor estimated that they had to do a lot of communication with people nearby.

If the communication work is not done well, it may cause resentment in the hearts of these people and leave future troubles.

So it's important to have a clear map and clear indicators at the borders.

Fan Jingjing is ready to bring out a field of surveyors who can draw maps.

She had to hand over some principles of cartography to these people, even if Fan Jingjing was not very familiar with the principles, it might be a major knowledge for this era.

What's more, the staff who drew the map is considered to be the manpower of the military department, and the map can be regarded as a national defense secret.

However, drawing your own territory should not affect Datang's safety.

If you want to teach them how to draw a map, you must go deep into it to investigate the situation before you can teach them by hand, and as for how to improve the map in the end, it is their job, Fan Jingjing can only pick a small area and use it as a teaching field.

These people have to leave agriculture full-time to do the job.

And you have to be very smart and be able to live in the mountains, so you think about it. The Fan family manor seems to lack such talents.

The people of the Fan family manor are now raising themselves too well with various benefits.

So Fan Jingjing looked at Liang Shu and asked:

"When you come to the Fan Family Manor, you are also familiar with the people in the vicinity, do you know who is more hard-working and more able to crawl in the mountains, we can welcome them to join the Fan Family Manor, and do not accept other assessments, but we must make sure that he is loyal to the Fan Family Manor.

Otherwise I teach them the art of drawing maps, and if it spreads, I may be slaughtered by the emperor, and drawing maps, which in this era is a national defense secret. What's more, I can teach how to draw maps, and I guess I am more clever than Gong Fanglang. ”

"The land that the eldest lady has been allotted, there should be a lot of wild people in the mountain, and these wild people in the mountain may not have any contact with the outside at all, so they don't know that the outside is too peaceful, so they don't come out of the mountain.

Maybe we can find some people from this, and even some people when they fled to the mountains to live, they brought a lot of belongings, and they can be regarded as scholarly heirlooms.

If we spread the news of the arrival of Taiping and co-opt the people who belong to our district, we may be able to get talents in this area, and even let them continue to stay in the mountains, but some of them may have to report to the county government to do population registration.

After all, the emperor wouldn't believe that the eldest lady couldn't even find a single person after accepting this mountain. ”

Liang Shu has also been reading and reading recently, and has learned a lot of things, he is already smart, and his brain is very flexible, so he also has some guesses about the emperor's thoughts, of course, these speculations are the thoughts of ordinary people, in fact, Li Shimin's thoughts may be more than they turned.

Fan Jingjing was also able to guess a little, because the emperor seemed to think that Fan Jingjing had unique abilities, so he wanted to help Fan Jingjing help find more taxpayers to come out.

In fact, Fan Jingjing is now in the manor, and many of them are original savages, and using these people to win over the people in the mountains should have a better chance of getting help from these people.

What kind of life they live in the Fan family manor, I don't believe that the people in the mountains will be moved when they hear it.

What's more, this place already belongs to Fan Jingjing, if they continue to live in the mountains, it is tantamount to taking Fan Jingjing's interests, and they must be told clearly, how they should live in the future, and make arrangements to make them live better than before, then no matter how they lived in the past, they will naturally integrate into the Fan family manor.

Or become a person in Fanjia Town, next to Fan's manor, for whom paying taxes is an important issue, but if they have a greater ability to earn, they will no longer pay attention to these taxes.

You need to pay 10 yuan in tax, but you can get 1,000 yuan in income, which is very different from the previous 10 yuan tax you had to pay in tax, but you only have 20 yuan in income.

What's more, now you may be able to get twenty dollars on your income, unlike the one that you could only get ten dollars before, but when you come out, you can get a thousand dollars.

To choose to come out or not to come out?

I believe that most people are wise.

And under the protection of the Fan family manor, that is, when they join a large group, they can know that they are not as vulnerable to bullying by local officials or local bosses as before.

The situation of the Fan family's manor, the savages who joined in the early stage are very clear, if there is any dispute, there is a so-called manor court to be responsible for the referee, and it is really not even a matter to send it to the county yamen.

They were more in agreement with the manor court's ruling than with the county magistrate's crackling and spanking ruling.

Although Fan Jingjing was in a hurry, she still knew that it was very important to choose people.

The newcomers are not necessarily unfaithful to the Fan family manor, and now there are no suitable people in the Fan family manor, even if some suitable people are women, if these people sit down to do things, it is okay, but if they want to go to the barren mountains to explore, it is impossible to do it according to their previous living habits.

Maybe it's because Liang Shu's interpersonal relationship is infinitely expanding, although it's not as good as Sun Erlang's interpersonal relationship, but the interpersonal relationship is also good.

And he not only knows the people of the Fan Family Manor, in fact, if there is anything outside that he wants to bring to the Fan Family Manor, he will often look for Liang Shu.

It is also because there are a lot of old ladies in it, there are many people who want to get married outside, seeing so many ladies inside, and they also have a relatively good income, they all want to propose to the ladies in the manor, but the ladies in the manor don't want to marry at all, but they want some men, so some people outside have a relationship and have children.

Liang Shu is also a source of trouble, because he knows that the women inside are too strong, and it is really not easy for the men outside to deal with the women in the Fan family's manor.

And many of the women in the Fan family's manor are already relatively old, and there is no way to be submissive like a little lady.

Most of them have a big temper and have their own opinions, and after studying, they feel that they are very different from before, and most of the people outside the Fan family manor have no opportunity to get an education.

It is inevitable that people will compare with each other, when a person has knowledge, he will have more room for growth, and you don't know people, although there is also room for growth, but the space for growth will be relatively limited, depending on whether your interaction with people has no way to pull you, or it has something to do with opportunities.

Liang Shu brought a dozen people, most of them from his old village, and some of them were nearby hunters.

These people lived fairly well in the original village, and they didn't flee to this place.

This time, Liang Shu recruited these people in the past.

He thinks these Orions are good people.

In fact, although the Fan family manor has only been established for a few months, its reputation is getting bigger and bigger, and the most famous is that the harvest of working in the Fan family manor has been spread, and many people want to go to the Fan family manor to study, and then go home to farm, even if there is no way to grow such a high-yield grain, but only half, it is enough for them to become a person who can be fed, clothed, and warm, and have a surplus.

Before leaving, Fan Jingjing had a lot of preparations.

At the beginning, these people had to be trained, if it weren't for the emperor to send someone to urge the survey of the boundary, Fan Jingjing would have wanted to set off later.

Of course, before setting off, Fan Jingjing. also asked people to prepare a compass, the compass is an ancient Chinese invention, not too difficult to find, in fact, for Fan Jingjing, as long as there is a magnet, it can make a compass.

It is much easier to draw a map with directions, not to mention that Fan Jingjing does not plan to draw longitude and latitude lines according to the principle of the earth's rotation, but just wants to draw a map of her land.

The distance is not large, and the error is negligible.

The preliminary purpose is to draw the scope of Fan Jingjing's land first, and in order to be clear at a glance, the boundary must be made along the road, for Fan Jingjing, the way she demarcated the boundary was just to tie a straw rope at first, and then sprinkle a bunch of flower seeds, and then let the land moisten a little, and then let the seeds grow.

These seeds are the seeds of flowers and plants.

Fan Jingjing originally wanted to talk about the seeds of these flowers and plants, but he could only give up, after all, there were so many fields for her, and now she was short of food, so she mostly planted something that could be eaten or what she wanted to eat.

There were many bags of seeds for her flowers and plants, and Fan Jingjing mixed them into the mud and sand and sprinkled them on the ground along the way.

They are not only responsible for sowing seeds, but also for drawing maps.

In the way of drawing the map, Fan Jingjing used a lot of triangulation methods.

It turned out to be too slow, because each calculation of the bearing had to go through a lot of calculations, and there was no basemap.

The yellow-colored paper in the hands of the officials sent by the yamen couldn't be read at all.

Compared with the mapping methods of this era, it really takes more time, and these people have no mathematics education, although Fan Jingjing's absorption ability to teach them while walking is still relatively weak, but they seem to have a great enthusiasm for learning new knowledge, so when Fan Jingjing is teaching, they are very serious.

Speaking of geodesy, Fan Jingjing is not very familiar with it, she just uses the concept she can remember, find a way to figure out her bearing, and calculate the distance, record a few special points, and calculate her bearing through the angle and height difference with this special point.
