Kang pot, like kang and pot table, can cook with fire. Let's start with science popularization: "Lian Guo Kang", also known as "Zao Lian Kang" and "Lian Guo Kang", is an indoor building facility integrating cooking and heating, which is common in northern Shaanxi, western Inner Mongolia, northwestern Shanxi, Ningxia, Hebei and some rural areas in Northeast China. This is a portrayal of people's life when they went to the cave in the depths of the mountains in the past: on one side of the hole is a kang, and behind it is a pot table. When cooking in a pot, the heat energy of the fire in the pot is transferred to the kang, which makes the kang heat up at the same time. This is a win-win situation. When the rice is cooked and the pit is hot, it will not be cold.
