On October 23, we ushered in the eighteenth solar term in the twenty-four solar terms – frost.
Frostfall is traditionally the start of the frosty season of the year and the transition from autumn to winter. In meteorology, if there is strong cold air moving southward during the frost season, the surface temperature drops to 0°C or below, and the water vapor in the air near the ground reaches saturation, which will directly decompose on the ground or near-ground objects to form fine ice crystals.

Frostbite is a colorful solar term. After the baptism of autumn frost, although the greenery in the northern region is gradually disappearing, there are many dazzling warm colors in the palette of nature in the fertile fields. The maple leaves turn red and the ginkgoes turn yellow. Under the sunlight, the layers of forests are dyed like rosy clouds. Although crops and grasses began to fall, the autumn chrysanthemums were in full bloom at this time. Since ancient times, there has been a saying that “the frost hits the chrysanthemum”. Therefore, the chrysanthemum was regarded as the “grass of the time” by the ancients and became a symbol of vitality.
