Inside the kang is a kang hole, where people smoke, like a hole in a hole. Ordinary fire kang generally has four or five holes, while wrist kang generally has only one hole. When cooking on the stove, firewood burns in the hearth and smoke flows in the kang cave. When smoke floats from the chimney into the sky, the kang will gradually heat up. The kang is closest to the stove, so the hottest kang is a little closer to the chimney, so it is the coolest.

If it is winter or spring and autumn, the northeast people worry that the kang is not hot enough, so they use fire after cooking. The smoke board will be inserted in time. This is the valve of the chimney. After plugging in, a small amount of smoke in the kang hole will not send the chimney out. The hot air in the kang cave will not run out with the smoke, nor will it slip out by itself, because the valve is closed.

Kang is not unique to northeast China. In rural areas of northern China, kang is a very common thing. At the end of one hundred days, Jia Xuan smelled of medicine all over, and Hu lifted the taboo in his heart and pulled off his belt. They were as enthusiastic and greedy as they were, and they didn't feel satisfied or sleepy until they collapsed the adobe on the two-page kang surface. They moved to a nest with a smile.

In the former rural areas of northeast China, kang can be divided into south kang and north kang, that is, one room is paved with two kang, one in the south and the other in the north, which are used to live people. In addition, the wrist kang is not necessarily used to put cabinets, but it is also possible to live in people. Because of the large population in rural areas in the past, kangs could not be divided into upper and lower bunks like beds, so they could only be divided into north and south.
