The fire kang is used in this place, and Yang Qiao has no way to do it.

Yes, before, the large class in the school, what small class, or middle class, all used stoves, but the stoves in small classes and middle classes were watched by special teachers, and in large classes, the students were responsible for themselves, and even, the children in the large class could go to the mountains to fight the pine tower by themselves.

However, this time, Yang Qiao has magnified this age, that is, it has been changed to elementary school to have this kind of thing, and the primary school is a stove, although it also uses a fire kang, and there is even a fire wall, and even, there is a fire wall similar to a fireplace, but the doors and windows are not so sealed, in order to prevent any poisoning.

And only this enlightenment class, this heating is more troublesome, the stove of this kang is placed underground, oh, just a basement, there is a huge space in it to put firewood, grass and coal, the podium above, that is, the heat dissipation source of the kang, and the flue, but Yang Qiao and the chatter have gone through strict calculations, and after the virtual chatterbox, many improvements have been made, and the drawings are officially released, well, because this drawing is through the help of the chatterbox, so, this drawing, is strictly confidential, will not be passed on, and the workers, how much can they learn, It doesn't matter how much it is passed on, besides, this kind of usage is really not very much, so the chatter will help.

What, an earthen kang, will be so strict?

Oh, it depends on who you want to target, a group of children, especially, for many years to come, there will be Yang Qiao's children to go to school here, if you look further back, if you look at it from afar, then there are Yang Qiao's grandchildren, that is, that sentence, children and grandchildren, endless.

Therefore, for the sake of one's own family, no matter how good it is, it is not too much, so others will be stained naked.

And the heat dissipation method of this earthen kang is a little troublesome, and it can only be dissipated around the podium, which is too hot, and the baby will be scalded when it comes over, and if it is too cold, the temperature in the room will be too low, so it must be strictly calculated.

"What, I calculate, not to mention the standard of a spaceship, but also to meet the standard of a space shuttle, what, it's too exaggerated, what technology, there is a minimum and a highest, isn't it? I've designed it to the highest standards, who bites me! ”

What, hot in summer?

Such an insulated room, moreover, Yang Qiao's plan around is to focus on turf, that is, the hard playground, which has to be away from the classroom for a certain distance, and will not let the heat of the hard playground radiate to the classroom, so, at most, in the hottest weather, put a few buckets of ice cubes in the classroom.

What, where did the ice come from in summer, not to mention this traverser's summer ice-making weapon, Yang Qiao can not know, especially this saltpeter, he still uses a lot, and even, this saltpeter, he uses it in soil and fertilizer.

"So, brother, is this chimney smoking?"

"Well, now they're trying the effect, you don't feel it, the test is the best this summer, and it can also heat the inside of the room, so that the moisture inside can be dispersed as soon as possible."

"The effect of the summer test?"

"If you think about the stove we use, is it a little hot, and this stove is not easy to burn, not counting such a thing as a reverse wind."

"Oh, that's really it, oh, brother, I also understand, why do you have to let the babies learn some common sense things, just so that they can recognize these things, um!"

Xiaomei couldn't say what Yang Qiao meant.

"Well, just don't let them be deceived, yes, it's deceived, this, ask your second sister-in-law to know, for example, the palace buying, go outside, go to buy vegetables for ten yuan, but come back and quote that this is bought for ten strings of money."

"Ah, what would it look like?"

The little sister was stunned, this, in the Yang family, there is really no such deception, but at this time, the Yang family in Chang'an City does not know what to do.

I don't know, I know, at least the old lady knows.

"Deceived, butler, do you think I should tell the baby?"

"So, old lady, what do you mean?"

The housekeeper was a little puzzled!

"I mean, don't debunk it, remember it first, when the big baby can find out by himself, and then say, or, you can tell the big baby by knocking on the side, but you can't tell him directly."

"Well, okay, the old lady's idea is right, my Yang family still lost this money, and even, this family, even if there is no penny, there is still Lang Jun here!"

"Well, that's what you said to me, but in the future, I don't want to hear it get out."

"Okay, old lady, the old slave understands, the old slave understands, then, the old slave has retired."

"Go, don't be an old slave, let people think that the old body is not as good as Da Lang!"

"This is deception, family, but, brother?"

Xiaomei was puzzled.

"Are you questioning how I know, or are you asking my mother's plan, I'll first say how I know, do you really think, at home, I don't care, this is just a strategy, okay, you know it's done, in fact, in some families, and even in the noble family, there is always this, that way to avoid disasters, otherwise, a family, how can it be passed on for a long time, and we are now from nothing, to have, so, we need to be more ruthless, and, what do you think my mother is doing, she is cultivating a big baby, understand."

"Oh, oh!"

Xiaomei was a little stunned, this, can you still operate like this.

"Okay, little sister, don't pay attention to your brother, he may be exaggerating, but this kind of thing really exists, even in our manor, there are such and such false reports for that purchase, this is still a subordinate who signed a slave contract, but even if we know that as long as the scope of this false report is not very large, we can only turn a blind eye, this, when you become the head of the house, you will know."

"The head of the house?"

Xiaomei thought about it, but no, that stinky boy is the boss, isn't he the heir to the head of the family, and herself, that is naturally the head of the house, if not, the brother must be unwilling, that is, the stinky boy is not the head of the house, he is not the head of the house, this, is within Yang Qiao's control, I didn't expect my brother to do so much for himself.

Ah, by the way, there is also the eldest sister, although the relationship between the eldest sister and her brother does not seem to be so good, but the eldest sister seems to have benefited more.

The little sister thought thoughtfully, thinking.

"Understood?"

Li Lian looked at her little sister with some amusement.

That, that is, only Li Lian can explain these problems, and the other six people, that is, daughters-in-law, do not have this vision, or this experience.

In other words, why Li Er was so resolute in sending Li Lian over so quietly, and he didn't have any intention of helping Yang George's family, but he didn't expect that Yang Qiao had more than he thought, and Li Lian, indeed, also played a great role.

In short, who can say clearly about the things in this world, how it should be, and living comfortably is the best.

"Let's go, I'll take you to the basement."

That's a lot of talking.

"Daddy, it's hot, don't hold it."

"If you don't hold it, we'll meet, let's take a look and leave."

"Lang Jun?"

A worker with a gray face saw Yang Qiao come in and quickly came over to greet him.

"Well, how's that?"

Actually, this, you don't need to ask, you know what's going on, there's a bit of smoke in it, which is normal and not smoke from pouring smoke.

"Lang Jun, very good, the design of this flue is quite reasonable, I have never seen such a good fire kang!"

This craftsman is very excited, you know, he is a craftsman who has learned to build a fire kang, and even a craftsman with the title of engineer, but the current situation makes him feel very excited.

"Well, the drawings are going to be read."

However, it's just not optimistic, and others can't copy it, right?

"Okay, Lang Jun, this drawing is firmly in my mind, and without Lang Jun's arrangement, I will never make such a kang for people."

In fact, he still didn't understand the meaning of this fire kang, you know, at the beginning, Yang Qiao personally commanded, although he only moved a few bricks, but he didn't understand the importance of those bricks.
