Sprinkle water on the ground to adjust the indoor temperature. In winter, the climate tends to be dry, and some fresh water is often poured into the room, which can not only maintain a certain air temperature, but also increase the indoor temperature by 1 to 2 degrees.
The temperature at the top of the room is much higher than that of the floor. Sprinkling some fresh water can make the hot air at the top of the room flow to the ground, so the indoor temperature rises slightly and the indoor air is warm and fresh.
