Historical origin:

There is a proverb in China called "Dew first turns white and then cold", which means that after the dew festival, the dew turns from a little coolness in early autumn to a little coolness in late autumn. There is also a proverb about cold dew: "Cold dew spans three dynasties, and you need to find a bridge after crossing the water", which means that the weather is already chilly and you can't wade across the river or go to the fields barefoot as before.

During the cold dew, people can obviously feel the change of temperature difference. From white and crystal dew to freezing cold, it vividly reflects the continuous decline of temperature. As the cold intensifies, everything becomes dim. Cold dew is the end of the full moon in the dry calendar and the beginning of the full moon. At night, looking up at the starry sky, you will find that the "Big Mars" (Antares) representing midsummer has sunk into the west.

After the cold dew, the height of the sun continued to decrease and the temperature gradually decreased. Cold dew is called "cold dew" because the temperature is much lower than that of Bailu solar terms, and cold produces dew condensation. "Twenty-four solar terms" said: "In September, the dew is cold and will condense." At this time, the temperature is lower than when it is "white dew", with more dew and chill day and night.

Meteorological changes:

Wu Cheng, a scholar in Yuan Dynasty, compiled Twenty-four Solar Terms, which divided the cold dew into three stages: first, waiting for Hongyan visitors; Second, the sparrow enters the water and becomes a clam; Three chrysanthemums have yellow flowers.

It means that in this solar term, geese move south in a line or herringbone queue; In the cold late autumn, all the birds disappeared. The ancients saw a large number of clams suddenly appearing on the seashore. The stripes and colors of shells were very similar to those of birds, and they thought they were birds. Chrysanthemum blooms in yellow, indicating that chrysanthemum is already in full bloom at this time.

In the dew season, dew increases and the temperature decreases. At this time, the temperature in most parts of South China continued to drop. The average daily temperature in South China is less than 20℃. Even in the areas along the Yangtze River, it is difficult for the temperature to rise above 30℃, while the minimum temperature can drop below 10℃. Except for a few valley lowlands, the northwest plateau.
