"However, in the past, rich people used blue bricks for jointing, and even brick carvings."

"However, most ordinary houses are usually built of that kind of adobe, with a layer of mud or white lime on the back, but the structure inside the kang is more complicated, and the pot stove-flue-chimney must be formed to preserve An effective thermal circulation system that can reach the heat of every part of the heated kang and discharge it smoothly without leaking the smoke."

"As I said before, building a kang is a very complicated thing, not only in its principle, but also in its production."

"The kang should be raised on the ground to half the height of the kang with soil and sand, and then an S-shaped flue is built with adobe after compaction. However, it is also possible to build the flue first, and then fill it with an appropriate amount of soil and sand. "

"The earthen kang made in this way is stronger, and the surface of the kang is not easy to sink. And in the flue, there are actually a few pits called ash chambers for storing soot."

"After the flue is built, it is the Ankang noodles."

"This kang board is actually a bit particular. After ordering the size of the kang, four wooden strips must be used to form a rectangular frame in advance. The size inside the wooden strips is the size of the kang board."

"In the earliest days, this kang board was made of mud."

"Add some dead grass to the mixed mud to increase the stickiness of the kang board, and then put a few wooden sticks to fill it with mud. The wooden sticks here are used as keel."

"After it's done, let it dry and remove the frame, so that the kang board is ready. The kang used to be not very big, basically about two feet long, one foot wide, and three inches thick is enough."

"Furthermore, after such a kang slab is finished, mud should be used to fill the gap between the kang slab and the wall, so as to prevent the smoke in the stove pit from escaping from the gap."

"However... Even so, in fact, there will still be a lot of smoke when cooking."

Studio.

"Yes, yes, every time the fire is lit, the room is filled with white smoke!"

"No, when I was young, I couldn't do my homework every time I cooked, because it was too choking!"

"That's right, every time I cook, I have to go outside to let the air out in advance, and I can't even watch the TV that attracts me the most..."

"Yeah, it's okay in summer, but in winter, it's just full of snot and tears!"

"Still smoking?"

"Then there is no solution?"

"real or fake?"

"Is there no way to solve this?"

"Yeah, we have to find a way to avoid it?"

Li Yuan: "Of course there is a method, and it can be seen from the changes in the Northeast Kang."

"This kind of smoking kang was usually first made of mud, and the kang made of this material is easy to dry out, so it was simply replaced later."

"As far as I know now, the Northeast Kang is generally made of cement boards, with steel keels inside. Such a Kang hole is not prone to the previous collapse problem, and it is not easy to crack."

"And the position of the gap will also be directly covered with cement slurry, so that the wall and the cement board are perfectly combined."

"And the current kang, in addition to the cement board, will also spread a layer of fine sand or straw on it, and then spread a kang mat on it."

Studio.

"Why spread sand and straw?"

"Didn't the anchor say that the kang would be ignited before? But isn't it easier to ignite when laying straw?"

"I don't understand either, why do you want to spread these things?"

"It's not difficult. In fact, these things are laid to prevent the kang from being too hard!"

"So, the purpose of laying these things is to make the kang softer?"

Li Yuan nodded.

"Well, this friend has experience at first sight."

"That's right, because the cement board is very hard, even harder than stone, so if you spread a layer of fine sand on it, you can greatly reduce the pain."

"There are also straws, which are also used to make sleeping more comfortable."

Studio.

"But...you've already put so many things on it, why do you still feel panicky every time you sleep?"

"I think so."

"Haha, let alone you, I, a native of the Northeast, feel that the bed is too hard after sleeping in college for several years!"

"I won't argue with you about this. The kang in the northeast is really hard, haha!"

"It's good to be harder, it's good for the cervical spine!"

"Good for blood circulation too!"

"real or fake?"

"Of course it's true!"

"It's true. Because the Northeast Kang is relatively hard, sleeping more can improve those with cervical spine problems! This is the same as sleeping on a hard bed!"

Li Yuan: "I can't guarantee anything else, but sleeping on the heated kang is indeed very beneficial for dispelling dampness and treating rheumatism."

"Because the heat of the kang is very evenly heated, and enters the body from the skin contact. Unlike the air conditioners in the south, the hot air is passed out through a vent through the blowing method."

"Although this will blow the hot air to every corner, it will also make some patients with rheumatic bone disease suffer."

"And this kind of heated kang can play a very good role in combing. Although it won't remove all the cold air in the body, it does have a very good therapeutic effect."

"And the principle of the heated kang is that the hot air generated by burning fuel such as straw and branches passes through the flue of the heated kang to dissipate heat to the adobe, and the adobe is a poor conductor of heat, so the temperature of the adobe will last for a long time after being heated. Even in the coldest winter, when the kang is fired at six o'clock in the evening, the kang is still warm when we wake up the next morning."

Studio.

"It's been so long?!"

"I'll go, isn't it already twelve hours? It's still hot?"

"Yeah, isn't that too exaggerated?"

"It can last for a time synchronization? I don't believe it..."

"It's really hot for that long!"

"What's the matter, the kangs in the northeast can basically maintain such a temperature."

"God, I'm too envious!"

Li Yuan said with a smile: "The kang is indeed a very good invention, let alone you southerners, even I, a northerner, love it so much."

"Especially in winter, sleeping on the kang is an extremely enjoyable thing."

"And in winter, there is no need to spread too thick on the kang mat. A thin layer will better allow the temperature of the kang to be transmitted to the bed."

"In winter, after cooking and cooking, the kang is left to air for two or three hours to let the heat warm the house. Then spread the quilts on the kang."

"It takes less than 10 minutes to get into the bed, that's a warm one! People who are afraid of heat may not be able to fall asleep at all!"

"And it is precisely because of this that our quilts in the northeast are not too thick. After all... too thick quilts are impenetrable to the wind, but the body will definitely sweat when surrounded by such warmth."
