Cold dew coincides with chrysanthemum in full bloom, which is different from most flowers in spring and summer. The heavier the frost and dew, the more gorgeous the chrysanthemums are. In order to get rid of autumn dryness, people have the custom of drinking "chrysanthemum wine". Chrysanthemum wine is made from chrysanthemum, glutinous rice and distiller's yeast. It tastes cool and sweet, and has the effects of nourishing liver, improving eyesight, strengthening brain and delaying aging.
