During Cold Dew, the dewdrops become colder and may even freeze, indicating the arrival of chilly mornings and evenings. This period is characterized by a noticeable drop in temperature and the beginning of frost in some regions.

In Chinese culture, Cold Dew is a time to appreciate the beauty of nature as the leaves change color, creating a vibrant tapestry of reds, oranges, and yellows. It's also a season for harvesting crops and preparing for the winter months ahead.
