How big is the kang hole on the pot table?

Generally, 0.6 meters is a good measure, ranging from 0.6 to 0.8 meters.

After cooking, using the waste heat, fireworks pass through the heating hole under the kang, and then exhaust the outdoor atmosphere from the chimney.

Guanzhong people call the base kang a pan kang, which is usually carried out in spring and summer during the slack season. Pot kang can be made of brick, specially burned with coal, and there is also a fire kang closely connected with the cooker. Many times, it is a heatable adobe sleeping platform. Before paving the kang, the kang blank should be paved, and the soil and removed wheat seeds should be added with water to synthesize wheat straw mud, which should be beaten into adobe with a square of two feet on the ground and dried to form the kang blank.
