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 season of the starry sky changes, and the "Big Mars" (Scorpio Antares), which represents the midsummer, has set in the west. As soon as the cold dew passed, the height of the sun continued to decrease and the temperature gradually decreased.

Compared with the solar term of Bailu, the temperature of cold dew has dropped a lot, and the dew on the ground is colder, which is likely to become frozen dew, so it is called cold dew. "Twenty-four solar terms" said: "In September, the dew is cold and will condense." At this time, the temperature is lower than the "white dew", with more dew and freezing cold, hence the name "cold dew".
