Chang Po naturally doesn't pour tea himself, nor does he pour tea for Mo Yu, basically he still needs someone to serve him.

However, Chang Po was sweating profusely at this time, and on a cold day, he was sweating profusely, which shows that Chang Po still used a lot of strength.

The first thing I did after I came up was to take a towel and wipe it casually, and then let someone make tea on the water and tidy up themselves.

Bai Yun was also out of breath as soon as he sat on the table, he didn't quite admit it just now, but now he has obviously admitted it, although he doesn't admit it verbally, but it is indeed a difficult thing for him to have happened in physiological reactions.

Soon someone brought towels and clean water, of course, this clean water is actually from the lake, and there is no big problem when you use it to wash your hands and face.

But if you soak it for a long time, as mentioned earlier, there will definitely be big problems, such as some skin diseases, such as rotten sores.

There is no big problem with washing it once in a while, and there are people who drink this lake water is this lake water.

To eat the water of this lake means to use it for cooking, such as rice, for example, for stir-frying.

In fact, there is no big problem with this, but I am afraid that soaking in water for a long time, even if it is clean water, it is not a good thing to soak in water for a long time.

Naturally, the water for tea is that they bring some clean fresh water from the outside, such as well water.

Generally speaking, well water is the most commonly used water, in fact, it is the water in some relatively clean rivers, and the least is actually spring water.

Whether it is recorded in literature or in real life, it seems that people are full of praise for the spring water, but there are not many people who can actually eat and drink with the spring water.

There is no doubt that the spring water is indeed very good, one is relatively clean, and the other is that it is more delicious and drinkable.

But it takes a good condition to form this, and it still depends on the climate, and it is different when it is dry and when it is rainy when it is dehydrated.

In addition, there are some topographical elements, so there are not many people who can actually eat the spring water, and the well water is still the main one.

Of course, the deeper the well water, the better.

But even in such a powerful country, building a well is not an easy task.

Especially for some deep wells, such things even require life, because sometimes it will cause the well to collapse, so there is no need to say more, basically it cannot be saved.

No matter how hard you try, no matter how much you try to save this person, this is basically the case when you are buried inside.

The larger the well water, the better, and the area in contact with the water is relatively large, and the amount of water that can seep out is also relatively large.

That would be able to feed more people, and generally a village should have a well, and even better if there was a river.

But the state usually arranges for people to build this well.

In order not to lose human life, other methods are generally used.

As I said earlier, the fertility rate in this era is not particularly high, so human beings are still relatively precious, and it is indeed not a cost-effective thing for me to lose my life in order to see a well.

So in the later stage, reduce this effort as much as possible.

Even if you pay a little more money, you don't feel like it matters, so when you dig a well, you will change to another method.

Try to dig this hole a little wider.

It's like a funnel, dig a little bigger on it, and when you get water, dig a little deeper.

Then we started building with stones, which were used to filter the water and make it a little cleaner.

But such a method is really very labor-intensive, and a well dug by an ordinary method is even several times more expensive.

Therefore, the financial resources spent are several times greater, but because it is supported by the state, it will become slightly better.

The general method is to dig the well and pave the stone at the same time, so that the collapse can be prevented, but it is not completely prevented.

So there is also a certain risk.

There is almost no risk to this method, at most it will cost a little more manpower and financial resources, water is the source of all things, so it is necessary to make a rural village have water.

It is also the best way to maintain the stability and well-being of the grassroots people.

Everything else is basically the same, such as the wooden reels used to draw water, such as the location of the site.

Mo Yu had read such books before, although he had never actually operated them.

But when you know that when choosing a site, you need to look at the location of some plants, and generally there are such plants, which means that the groundwater may not be so high.

However, there are also places where you live in relatively high places, so the pits dug are also relatively large.

You need to dig a very large pit, try how big the pit needs to be dug through specific calculations, and then proceed down in a staircase shape.

It's very easy to get up and down.

From this description, you can also see how much effort it takes.

Generally speaking, a stone is placed around a circle, in fact, it doesn't matter whether the circle is a square or a rectangle, but generally speaking, it is a circle.

Putting some very long pieces of wood on the outside can also play a role in fixing and filtering.

The next step is to install the rope and the wooden grunt.

In some places, a turtle will be placed, which is of course a more traditional activity.

The main reason is prayer, and there is also a part of the literature that believes that the test for the presence of toxic gases or the presence of the water is poisonous.

Generally speaking, the well water that has just been drilled is not drinkable, on the one hand, there is sediment, and on the other hand, the quality of the water is not particularly good, so some organisms will be used to test it.

This can be regarded as a manifestation of cherishing human life.

Therefore, it is also a most basic but very common phenomenon, although it often exists in people's lives, but in fact, most people can't imagine it, but if you lose this award, how much turmoil will happen.

The people near the lake also dig wells, but the way they dig wells is actually relatively simple, the main reason is that the groundwater is relatively shallow, and if they do dig wells, they will rely on a relatively long distance.

First of all, let the underground soil filter some water, plus some stones, although it is not as good as the water from some inland wells, but it is relatively clean.

Before the steps were finished, the stones were laid on the ground one by one, and some ladders were used to build a very high one, and some of the wood on the outside was directly dismantled, and some were directly used to fix the stones.

The next project is to bury this thing, generally speaking, you need to get used to the water quality to see if you can drink it, and if you can drink it, it is basically to bury this thing.

Then let the animals pull the rolling logs or rocks back and forth, which can make the well tighter, and the well will be changed dramatically because of some ordinary change, such as an earthquake.

In this case, a well is basically completed, although it seems that the step is very simple.

But the first step is the most difficult, the first step needs to dig up the map is simply beyond imagination, you need to gather a very, very large number of people, you need to find a very large open space to put this soil.

But one thing that has to be said is that this method of construction will hardly kill people, of course, there must be fatalities, but it is definitely not caused by landslides.

If you follow the original construction method, you can actually build it with about three people, but this time is a little longer.

But this danger will actually increase dramatically, and most people will not be able to make an effective view of something underground.

I don't know what kind of terrain is underneath and what kind of soil is underneath, so I dig down rashly.

In fact, there is another situation, which will not only produce human lives, but also cause many people to have some phenomena of losing their previous efforts.

That's quicksand, quicksand doesn't just appear in the desert, it can easily appear underground.

If you dig up quicksand, it doesn't really matter, at most there is no water, and you need to find a new place to dig it.

But if there is quicksand on the top of the digging, the original time is to hold on, this is the original time when the surrounding terrain held on a little, but when you dig underneath there is some vibration.

There is no way to control the quicksand in this terrain, and when the quicksand is buried from above, no one can react at all, and it is buried directly underneath.

You can't dig it out, because if you dig it, there will continue to be quicksand.

This situation is also prone to occur, and the former means that there is nothing in the quicksand below.

But the latter's words are a real human life phenomenon, so this situation is still not good.

But if it's really like the method used in most places in the Polar Country, there shouldn't be much of a problem, because even if there is quicksand above, you can just run up from other places.

Anyway, it's all staircase-like, and it shouldn't be difficult to go up through the stairs.

It's just that this pit may be abandoned, of course, some quicksand actually has a relatively small time to work, that is, as long as this sand can be dug out, there should be no big problem.

After digging a well and filling it with sand, you basically have to plant trees on it, and the trees should not be too big, because if they are too big, the roots will absorb the water from the groundwater.

In this case, the well water may dry up during the dry season, and the trees planted in the first class are shrub trees, which are not particularly large, but can play a stabilizing role.

Some artificial grasses will also be planted.

Therefore, this well water can last for a long time, and some well water is very sweet.

Geology is a natural filter, and some may be stained with some delicious substances.

It's a bit much.

The boatmen on Changpo's boat quickly brought clean water, towels, and some tea.

A few people washed a little, and then watched the boatmen release the ospreys in the boats.

They are really powerful, and they don't feel the slightest fatigue after long-term high-speed rowing, and they can let these ospreys move around a wide area.

Once it is able to move in a large area, it is also able to conduct a large-scale reconnaissance, which means that some fish hiding at the bottom of the lake can be seen.

As a result, one after another big fish were caught, but Mo Yu could also feel the horror of this way far away.

Bai Yunyi asked a question that Mo Yu actually felt could answer, but it was Chang Po who asked, so Mo Yu didn't say much.

"Didn't you say it's just spring and winter? Why not fish in the summer? ”

Mo Yu still remembered the question he had said, and it seemed that Bai Yunyi also turned his face and forgot about it.

Chang Po smiled and said, "That's because the fish swim too fast in the summer, so there is generally no way to catch a good fish." ”

Bai Yunyi said another question: "Then how do these wild voices live in the wild summer?" ”

In fact, Mo Yu especially wanted to laugh, but he didn't laugh out for the sake of face, Mo Yu felt that this question was actually very, very easy to answer, it was simply too simple.

What do fishermen raise these ospreys for?

It must be to catch some relatively large fish, catch some relatively large fish to sell a lot of money, if you use the same strength to catch some smaller fish, then it may not be worth the loss.

Because ospreys seem to consume a lot of energy when catching fish when swimming, that is to say, the difference between catching a small fish and catching a big fish at the same time will not be particularly large.

Since it won't be particularly big, there is no need to catch it at all, so it's better to let them feed a little fish at home every day, which is almost enough for a day's energy consumption.

But not in the wild, where no one feeds them fish, so they have to catch their own fish.

But for them, the big rain and the small fish are all the same, they are all able to replenish energy, but for humans, this time it is very unacceptable.

Because the big fish and the small fish are very, very large, although for them, if these things reach a certain amount, the energy content is about the same.

But if a person lives in society, he needs money, and a big fish needs to spend more money per catty, so it can bring more income.

Therefore, fishermen will choose to keep those ospreys at home as much as possible in the summer, and just feed a few small fish to eat, regardless of the species.

There is no need to think about eating fish like humans, eating more spines and less meat and less meat, they are basically swallowed whole.

Therefore, in the fish market, it is enough to buy which one is cheaper, as long as it can be eaten by them, maybe two or three small fish a day is enough.

At home, he didn't move, he just stood there.

In the spring and winter or autumn, release them and let them catch fish, some of the larger ones.

And then buy some smaller fish for them to eat, it's basically one such step, basically one such process.

Therefore, this explanation should be something that Mo Yu thinks can be explained, Mo Yu also had such a question at the beginning, but after reading the introduction of some books, he also understood what kind of thing this thing was.

This time, Bai Yunyi asked again, and Mo Yu wanted to answer, but Mo Yu didn't answer.

Chang Po said: "Their survival in the wild is to catch some small fish and shrimp, and they can basically survive, but if they are artificially raised, it is not worth catching some small fish and shrimp." ”

Although the language is concise and some things are not described, such a description is already very good.

Basically, I told the story as it was.

Bai Yun nodded: "It turns out to be like this, I said why I can't see a fishing boat catching fish like this when I come out in the summer." ”

In fact, the theory is theoretical, and if you really want to talk about this matter, there will still be people who release ospreys in the summer.

However, one of the biggest reasons to release ospreys at this time is to feed themselves, and only for those who have nothing extra to earn a living.

In other words, if there are people who have extra income, they will not waste this time, they will not save a little money, because even the amount of money these ospreys spend every day is a decimal.

It is not particularly high for the overall amount of money earned, and saving this little money means that there is no other livelihood, and those things can be released to feed themselves.

It would be better if you could happen to catch a big fish again, but the probability of such a situation is very small.

So this kind of thing is basically like this in general, and it's normal for Bai Yunyi not to see it when he goes out to play.

Because the number is very small, the various livelihood systems implemented by the extreme country at the grassroots level are still relatively good, and the most important thing is because of commerce.

The prosperity of commerce makes this system a little better, and the advantage of this is that the ability to resist risks is relatively strong, whether it is the ability of the country to resist risks or the ability of the grassroots to resist risks.

It is not because of some natural and man-made disasters that some families have no way out, and the money spent is not very much.

At the beginning, I felt that a lot of money was spent on this matter for the state, but in the later stage, some tax revenues and some relief funds that were not paid due to natural and man-made disasters have basically returned.

So this kind of thing is a relatively good thing for the whole country.

Therefore, there are not many people who make a living just by releasing ospreys.

Chang Po naturally doesn't pour tea himself, nor does he pour tea for Mo Yu, basically he still needs someone to serve him.

However, Chang Po was sweating profusely at this time, and on a cold day, he was sweating profusely, which shows that Chang Po still used a lot of strength.
