It is not a simple matter to improve the water conservancy construction in a place or a house.

What Qian Rujun asked the students to do in various places was not to bring water into their homes, but to bring water into the fields with the help of waterwheels.

If they want water, they have to dig their own roads to their homes.

Or when the water tank passes through its own village, find a way to dig the water in the village and bring in the water.

After a continuous diversion of water, it is necessary to ensure that there is water available from beginning to end in the area where the water passes through.

Therefore, at the end of the reservoir, there is often a river, which can drain the excess water without causing a disaster.

In some places, excess water is turned into lakes.

But there are still risks because the lake has no way to communicate with the outside world, and it will form stagnant water and accumulate all kinds of things.

In the end, what they accumulate will only become a breeding ground for bacteria.

Such lakes look beautiful, but they often cause harm to the people who live around them.

Therefore, although it was able to be collected into a beautiful lake, Qian Rujun built a water reservoir this time, but did not cherish the water resources, but discharged the water into the river.

Qian Rujun knew that the river water discharged was still clean, and when it came to the next place, it could still provide the downstream river for use.

It's just that the change of the seasons throughout the year will make some times, the water flowing into it is not so popular.

If it's water that's in the river, people don't have anything to say, but if it's water you drain in, people find a reason to stop your actions or cause a discord in a place.

Basically, at this time, the countryside could build houses next to the fields, and the law could not control so many things.

But the biggest problem is that the law and order in this era is not good.

When the law and order is not good, even if you are working in the fields, you must always be on guard, and often several farmers will take care of each other.

The village will also pay more attention to interpersonal relationships, and if you are hated by the people in the village, it will be difficult to survive in the village.

At this time, you may be somewhere, inexplicably dead.

Not only farming, but also people in the village when they had to rest at night.

One person can't do everything, and the power is too small, so at this time, people will choose to live together, try to increase their power, and if all their clan power is not strong enough, they will also absorb trustworthy outsiders.

At night, the men had to continue working, everyone had to take turns to keep them safe, and the strongest people in the village had to have shifts.

In Dahan, the night is definitely not peaceful, and some bandits will come to your village during the day.

And then, when you sleep the deepest, lift up the torch and come to you for trouble.

In Dahan, there are already many people who are in a 24-hour working state.

Most people's lives only have a memory of labor.

Many people have to work more than eight hours.

The farmers are quite relaxed, and their working conditions are related to the weather.

Farmer's savings are also experienced in every aspect.

Some of them, in order to save water and time for washing clothes and reduce damage to clothes, even some farmers will find a group of people to go down to the fields in the middle of the night to plow.

Because in the summer, if they work during the day, they will sweat a lot, and the physical loss will be very fast, that is, they will need to replenish a lot of food.

So they simply slept in the house during the day, and took advantage of the night when the sun was weaker to come out and work hard.

Moreover, there is no need to put clothes on your body when you go to bed at night, because in the dark night, no one can see them, and the clothes will be less dirty.

This is the wisdom of civilians.

Civilians imitate most of the things that happen around them, as long as they see the people around them, have new inventions, or new experiences, they will try to imitate.

Those who are imitated will not cherish themselves, and they are happy to confess their skills.

But imitation also has limitations, if imitation requires some money, the initiator needs to imitate the materials, need to buy from other places, then you must think about whether you are suitable for imitation, how much it costs, and how much they can get from it.

If these supplies have to be found in the field, then in this era of inaccessibility, all the materials obtained from the field are expensive.

Unless you have something that the other person needs and can exchange it with the other person, otherwise, you don't have the conditions to imitate.

At this time, the gap between the rich and the poor can easily distance people.

People who want to imitate, even if they want to imitate, there is nothing they can do.

If this imitation does not cost anything, as long as their own labor force, or comprehension ability, absolutely do not need to hesitate, they think that the comprehension ability is not enough, they can make up for it with diligence.

And most things in the world can almost be done diligently to make up for the shortcomings.

There are some skills, so you can do it with your hands, especially the things of skills, if you don't have the psychological preparation of hard work, it is not easy to improve.

But you have to work hard, not just if you want to, some skills need to be repeated constantly.

If an ordinary farmer can't use them at home, how can he work hard to exercise his ability?

They can only do it, and they can use it for themselves. Unless, his skills are welcomed by the whole village, and he must work constantly.

But in the countryside, you have to work and have to come and go, and if there is no way to give you something in return, you may not be able to do it all the time.

The most important thing is that you should also take care of your own field, if you are not a landlord, basically there is no opportunity to exercise diligently.

The reason why they don't imitate is not that they don't want to imitate, but that they need to spend more time to imitate, so this imitation will have a delay.

Or just be able to use it. As for refinement, in the case of ordinary farmers, it is probably not too demanding, unless the individual has this talent.

As a traverser who has taken so many benefits, Qian Rujun has realized that she must pay more for this society.

to be able to repay the benefits she has gotten.

The benefit, as long as there is between giving and giving back, it can have a surplus, and in Qian Rujun's account book, it is earned.

Qian Rujun found that when he wanted to give, Qian Rujun had to do what he hated the most before, that is, to contact others.

Because even if you want to do things for everyone.

But in the world, there is no pure benefit, some people get good, some people get bad.

Even if you want to do things for others.

You also have to consult the audience so that he can know how he feels, and at the same time he is damaged, he can also know that in the future he can get more benefits from what you do than he loses.

That is, to know whether it is a good or bad thing for you to do this.

At the end of the Manchu Dynasty, there was a desire to improve transportation, so the construction of railways began.

But the people who were expropriated were dissatisfied.

They felt that building the railway would destroy their dragon veins.

So the railroad was laid during the day, and at night someone came to dismantle the railway.

As a result, these materials were brought to Chicken Leg Island and played a great role.

Although some things seem bad when they are done, they can prove to be good in hindsight.

It means that you have a vision.

But sometimes the vision has to be understood.

If there is no way to get understanding, it will add a lot of difficulties.

At such a time, you have to constantly brainwash the other person and tell him what kind of benefits will come in the future, so that he can give up the disadvantages that he sees in front of him.

Otherwise, there is no way to feel at ease when building. It tends to make people do inexplicable things, or even destroy this good thing.

However, the worst thing is that people who generally do this kind of long-term good thing do not seem to have a very good understanding of the things in front of them, and often ignore the reaction of the people.

So things didn't work out.

Before things work out, people will go to all sorts of negative situations together. The initiator, seeing the good, and even the people seeing more of the disadvantage he brings.

The bad always comes before the good.

The benefits may not necessarily be there, but the disadvantages are real, and these disadvantages may disappear in the eyes of the long-term visionary at some point. Or maybe he thinks it's an inevitable sacrifice, so. It doesn't matter if it's important, it's more important to trade it for greater benefits, but people don't think so.

Many people only look at the front of them, and even some people only look at the benefits and dangers in the distance in order to walk steadily, and the benefits and dangers in the distance will make him inadvertently miss it.

Qian Rujun's vision is very far away now, and he can see the secrets hidden after 2,000 years.

But a little earlier, she knew about some big events, and a little later, she didn't even know what was happening in the time.

That is, she has no vision, as I said earlier, she only sees an acre and a third of land under her feet.

But now she is in Dahan, and in Dahan, it is very enough to see the 21st century.

Basically, the common people of the twenty-first century have been very happy.

Even blissful to the point of being a little shameful.

Things don't taste good, and they'd rather throw them away.

The food they throw away feeds even more people.

But even if his eyes can see what will happen in the middle period of time after two thousand years, or even in the era of Emperor Liu Heng.

The hidden thoughts in people's hearts, but Qian Rujun doesn't know.

She only knew that in this era, there were still very many people who were interested in rebellion.

A piece of history in the middle, in front of Qian Rujun's eyes, seems to have been repeated, except for the useless Four Books and Five Classics, Lunyu Mencius, there are not many useful things left behind.

For Qian Rujun, this period of time is very dark.

Even if she knows history, she doesn't know if it's true or not.

Because after she came to Dahan, she found that there were many people in Dahan who were not people she could understand.

Almost everyone, in history, has a different face.

Perhaps, this is because the person who writes the history book, he is looking at things, or doing things, but from one side.

It seems difficult to understand a person in all aspects.

And Qian Rujun's angle of entering the historical stage is originally different from that of orthodox historians.

Even more cowardly than most people. Therefore, it is normal for Qian Rujun to have a different view from ordinary people.

Although Qian Rujun also has some interest in the history of later dynasties, Qian Rujun's contact with history is because history is originally the life of many people, so there are many stories later.

Most of the books she reads record some stories.

Even if the story is too boring, Qian Rujun is not interested in reading it.

It has nothing to do with the story, so she understands some of the key points of the history exam.

These key points, in fact, are not very real.

Because, the exam can't have too many controversial points.

But does it really take 2,000 years to change a person's perception?

Qian Rujun thinks it is not.

In Qian Rujun's view, human life is only a hundred years, and if the transformation of all concepts takes a hundred years to achieve, it will be too long.

If it takes more than 30 years for the concept to change, the human species would have been buried in the dust of history long ago, and the life that the earth is responsible for controlling will not be humans.

The history recorded in later generations proves that some wild islands are still in the primitive era, but if they do not resist the changes brought by the West, they will be able to quickly enter the 21st century, and even if there are capable people in the territory, they can lead the people to develop an industry in a certain industry and get rich quickly.

If you want to get rich, you must have someone in the territory who can lead you.

And the leader must know some words, as well as the classics that record scientific words.

The reason why they can't keep up with others is that they have to spend a while training their people in advanced directions, and advanced countries have the opportunity to prevent them from developing their own things.

With intellectual property rights in the world, as long as you invent something, even others can make it without asking you, but others will have to pay you.

Even if you're a farmer, you can't plant as much seed as he does, but you need to pay them if you prove that the seeds you use are unique to their company. And the seeds are what you painstakingly collect. As long as the other party has intellectual property rights, you have to pay them.

In this way, Monsanto applied for intellectual property rights for many native species in the world.

Their company has also formed an inseparable bond with the court.

No one is more ignorant than a farmer and more likely to step on this mine.

Embracing new ideas is the way to make a quick difference in their daily lives.

Qian Rujun knew more or less about the advantages or disadvantages from some hindsight in later generations, which may have been brought about by the changes she made.

Qian Rujun knows that everything has multiple aspects, but she has to do basic construction, which is the beginning of future development.

For better or worse, transportation needs to be improved and people need freedom so that people's happiness will increase.

It is Qian Rujun's wish for people to achieve greater happiness.

Although the opinion of the Han people was not sought. But Qian Rujun stubbornly wanted to achieve the common desire to be fed and clothed.

In fact, there are a few people who don't want to be fed and clothed, but they, a small number, don't have to worry about their existence.

Because they can choose for themselves, don't be fed and clothed.
