It won't be too dirty. My hometown is in the northeast rural area, and I have a deep understanding of this.
kang, also known as fire kang, is a common internal structure of houses in rural areas of northeast China, and has the same function as a bed when sleeping. The kang in the northeast is usually heated by fire through the kitchen pit. The temperature of firewood burning under the kang warms the kang, and the kang provides heat for the whole house again. Some people think that burning firewood on kang will get dirty and affect sleep, but it is not. The surface of the kang is made of concrete and steel bars, which is sealed and can completely avoid the dust brought by firewood. At the same time, the soot produced by firewood combustion will also be discharged from the chimney with the designed air duct.
at the same time, the kang in the northeast will be covered with a layer? Kang mat? The kang mat is made of soft plastic material, and its appearance is very smooth. Even if it is contaminated with dust, it can be easily wiped off. In fact, it eliminates the step of cleaning sheets in the south, but it will still be clean and tidy. The heated kang in Northeast China is very hard, so sleeping directly on it is easy to cause some problems of cervical vertebrae and waist. Therefore, people in Northeast China will put an extra layer of bedding on it before going to bed, sleep on it, and then completely fold it up during the day and put it in the cabinet. To sum up, it is actually very neat and clean for the northeast people to sleep on the kang.
Next, let's talk about the northeast people eating on the kang. Northeasters eat in two ways, one is to set a table under the kang, which is similar to that in the south, so I won't go into details. The other is to eat on the kang, and the old northeast families usually use something suitable for their own size? Kang table? Come to eat, put the dishes and rice on the kang table, and the family can start eating around the table on the kang. In fact, this situation is not much different from eating on the ground. Both adults and children will eat carefully and will not let the food spill on the kang. Even if it is accidentally spilled, it can be easily wiped off with a towel, thanks to the artifact of the northeast fire kang. The kang mat is not only dirt-proof, but also generally waterproof, so whether you eat or sleep, the fire kang in the northeast is clean.
