How to make a kang bed?

The general practice of kang bed: first build a few small walls and eight rows of bricks on the ground. Only a few pillars with red brick bases are supported and covered with several large cement slabs. Then divide the space into several tunnels, leaving blank at both ends to connect the tunnels. The surface is covered with adobe, slate or red brick. Finally, cover it with reused sand mud or white ash and smooth it. If the surface is uneven or uneven, it is normal, because there is extra air entering, so there is no need to pay special attention.

The structure of northeast kang is far more complicated than that of bed, and the construction methods are different, including hole kang, flower kang and hollow kang.

Kang bed is actually not a bed. From the traditional function and style, it is a combination of wooden chairs for receiving guests, with one long and one short in the middle and one chair at each end. In the form of a kang, there is a wooden bed board on it that can be opened. You can put the pulverized coal in and cover it with ash. You can keep the temperature for a few days, and then continue to spread the pulverized coal after the pulverized coal is burned.

Extended data:

Kang bed refers to a sleeping platform made of bricks in the north. There is a hole below, which is connected with the chimney and can be heated by fire. Although most buildings in northern cities have no kang but beds, kang appeared much earlier than beds. Zhang Guoqing made a textual research in the article The Origin of the Northern People's Custom of worshipping Kang, and the biography of New Tang Dynasty in North Korea stated: "(That person) always works as a kang in winter, and burns a warm fire under it".
