As the saying goes, "there is a light snow all over the sky, and there will be a bumper year in the coming year." This is what the old people in the village often say every time it snows. Corresponding to what people often say: snow is auspicious and harvest is good; Wheat covered with three quilts means sleeping with steamed bread in the coming year, which means that there is snowfall in the light snow festival, which is conducive to the agricultural harvest in the coming year.

Wheat covers three quilts in winter, and sleeping with steamed bread next year is a metaphor and description. It means that the thicker the snow is in winter, just like covering wheat with three quilts, wheat will spend the winter warm and safe in the snow. This quilt can not only prevent the heat in the soil from spreading outward, but also prevent the cold air from freezing the wheat.
