What are the heatable adobe sleeping platform in Shanxi cave and its surroundings?

There are many heatable adobe sleeping platforms and heatable adobe sleeping platforms in caves in Shanxi. The heatable adobe sleeping platform is a place to rest and sleep, and also a heating device. It is against the wall on three sides, and the interior of the kang is made of adobe or bricks into vertical and horizontal passages, one end of which passes through the passage in the wall to the roof, which is the smoke outlet, and the stove fire with one end connected to the kang is the heat source.

The hostess stuffed firewood into the stove mouth to cook, and the hot air passed through the passage to make the whole kang heat up. The whole family sat cross-legged on the kang and ate around the kang table, or the whole family sat on the kang and chatted. The guests came and asked to take off their shoes and smoke and drink tea around the kang table. In some places, the economy is rich, so it is more convenient to warm through the fire tunnel through the firewall.

Connected to the kang is the wall opposite to the three walls of the kang, about 1 m away from the kang surface, which is decorated with various patterns and images. This is "Kangwai" and the picture is called "Kangwai Painting".

"Painting around Kang" reflects the spiritual life of farmers, including historical stories and legends, such as the golden toad of Liu Hai, the three tricks of Meng Mu, the pear release in Kong Rong, the twenty-four filial piety pictures, feather flowers, landscape figures and so on, which contain people's expectations for future life.
