Historical origin:

In Chinese folk, there is a proverb that "the dew is white first and then cold", which means that after the white dew solar term, the dew changes from a cool feeling in early autumn to There is a bit of coldness in late autumn, "white dew like frost". There is also a proverb about cold dew: "After three dynasties of cold dew, you have to look for a bridge to cross the water." This means that the weather has become cold and you can't cross the river or go to the fields barefoot like before.

During the cold dew period, people can clearly feel the temperature difference. The change from pure white dew to cold and condensing water vividly reflects the continuous drop in temperature. As the cold air grows, everything becomes increasingly desolate. Cold dew is the end of the You month and the beginning of the Xu month in the Ganzhi calendar. At night, if you look up at the stars, you will find that the "big Mars" (Antarse), which represents midsummer, has set in the west.

After the cold dew, the height of the sun continues to decrease and the temperature gradually drops. The temperature during Cold Dew and White Dew solar terms has dropped a lot, and the cold dew condenses, so it is called "Cold Dew". "Collection of the Seventy-Two Hours of the Moon Order" says: "On the Ninth Festival, the dew is cold and will condense." At this time, the temperature is lower than during the "White Dew" period, there is more dew, and it is chilly day and night.

Weather changes:

Wu Cheng, a scholar in the Yuan Dynasty, compiled the "Collection of the Seventy-Two Hours of the Moon Order", which divided the cold dew into three periods: the first period is the arrival of swan geese; the second period is the arrival of birds. The big water is a clam; the chrysanthemum in the three seasons has yellow flowers.

It means that during this solar term, swan geese form a line or a herringbone formation and migrate south in large numbers; in late autumn, when it is cold and the birds disappear, the ancients saw many clams and shells suddenly appearing on the beach. The stripes and colors are very similar to those of birds, so it is believed that they were transformed by birds; the fact that the chrysanthemums have yellow flowers means that chrysanthemums were generally in bloom at this time.

In dew season, there is more dew and the temperature is lower. At this time, temperatures continue to drop in most parts of southern China. The average daily temperature in South China is less than 20°C. Even in areas along the Yangtze River, the temperature is difficult to rise above 30°C, while the lowest temperature can drop below 10°C. Except for a few river valleys and lowlands, the northwest plateau.
