Kang has a stove mouth and a smoke mouth, and the stove mouth is used for burning wood. When the smoke and hot air generated by wood burning pass through the partition wall of the kang, the slate on it is heated to generate heat, which makes the kang generate heat. Finally, the smoke is discharged from the smoke outlet of the refractory material through the chimney. In the north of China, the stove mouth of ordinary kang is connected with the stove, so that the kang can be heated by cooking with firewood without burning it separately.
The position of the kang near the stove mouth is called "kang head"; The position near the cigarette holder is called "Shao Kang". Generally, the "kang head" is reserved for the highest-ranking master or guest in the family, and men or young people sleep on the "kang head".
Extended data:
Due to the long cold winters in northern China and Mongolia, the popular beds in the south can't resist the cold winters, so the people in the northeast invented the kang as a heating facility.
"Southerners learn to sleep in bed, while northerners prefer kang" and "fire kang" are heating and sleeping facilities invented by northern residents to adapt to the cold climate. In northern China, especially in Jiaodong, Shandong, the winter is long and the climate is cold. Farmers here are used to heating with kang in winter.
The main rooms of rural houses in Jiaodong usually sit in a row with three or four rooms facing south, and two of them have kang. There is a stove about three or four feet square in the outer door near the two doors. Between the stove and the south wall behind the door, bellows are usually placed.
There is a six-to eight-printed iron pot on the stove, and the flue connected with the stove chamber under the iron pot passes through the wall from the kang of two rooms to the chimney on the outer wall. The richer people have a utility room in the east or west of the East Room.
