In the Gregorian calendar, the Cold Dew usually falls around October 8, and more often refers in particular to the day when the sun is exactly at the celestial longitude of 195°. In ancient times, dewing meant that the weather became cold enough to reach the dew point, but not cold enough to reach the frost point.
Chrysanthemums are blooming everywhere around the Cold Dew. In some parts of China, people usually drink chrysanthemum wine, climb high mountains, and appreciate chrysanthemums to celebrate the Cold Dew and the Double Ninth Festival. Moreover, in ancient times people used well water to brew medicinal wine.
In northern China, the Cold Dew stands for the coming of late autumn, a time when the leaves turn red. At this time, people from Beijing enjoy going to Jingshan Park, Badachu, and Xiangshan to climb mountains and appreciate the red leaves.
