What are the implications and traditions of cold dew solar terms and traditional cold dew solar terms?

1, cold dew is the seventeenth solar term in the twenty-four solar terms of the lunar calendar, belonging to the fifth solar term in autumn, indicating the official start of the autumn season; The time is 10 when the sun reaches 195 on the 8th or 9th of the Gregorian calendar every year. "Twenty-four solar terms" said: "In September, the dew is cold and will condense." Cold dew means that the temperature is lower than that of the white dew, and the dew on the ground is colder and will soon condense into frost. In the cold dew season, Nanling and the vast area to the north have entered autumn, the northeast has entered late autumn, and the northwest has entered winter or is about to enter winter.

2. China divided the cold dew into three stages: "Waiting for the geese; Second, the sparrow enters the water and becomes a clam; Three chrysanthemums have yellow flowers. " In this solar term, geese move south in a line or herringbone queue; In the cold late autumn, all the birds disappeared. The ancients saw a large number of clams suddenly appearing on the seashore. The stripes and colors of shells were very similar to those of birds, and they thought they were birds. The third stage of "Chrysanthemum begins to blossom" means that the chrysanthemum has opened in a large area at this time.
