Historical origin of cold dew

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), which represents midsummer, has set in the west. After the cold dew, the height of the sun continued to decrease and the temperature gradually decreased. Compared with the solar terms of the Millennium, cold dew is condensed, so it is called "cold dew". Twenty-four solar terms say: at this time, the temperature is lower than that of "white dew", with more dew and cold day and night.

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 dew: "Three dynasties are cold and dew, 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 period, people can obviously feel the temperature difference change, from white, crystal clear dew to freezing cold, which vividly reflects the continuous decline of temperature. With the increase of cold, everything is gradually dim.
