Origin of Cold Dew Solar Term

On October 8 or 9 every year, when the sun reaches 195 degrees yellow longitude, it is cold dew. The word "cold" first appeared in the 24 solar terms. At this time, the wild geese flew south, and the chrysanthemums became yellow. Compared with the "white dew" solar term, the temperature was lower, the dew was more, and it was cold. As for the origin of the name of Han Lu, it is recorded in the history books that: "The Dou refers to Han Jia as Han Lu, which is cold and cold at that time, and will be coagulated, so it is called Han Lu."

What are the three phenology of the cold dew solar term

The cold dew includes three phenology: "waiting for the guests of the wild geese". The wild geese in the sky move southward in groups, sometimes in a straight line, sometimes in a straight line, becoming a beautiful touch of fine brushwork in the sky; "The second class bird enters the flood and becomes a clam". In late autumn, the cold air is very strong, and birds are hiding. There are many clams on the seashore. The stripes and colors of the shells are similar to those of birds, so the ancients thought that clams were formed by birds; "Three chrysanthemums have yellow flowers". The cold dew is about to end. The chrysanthemums all over the mountains are in full bloom overnight.

What are the folk customs of the Cold Dew Solar Term

In the cold dew season, the northern part of China has presented a late autumn scene, and the southern part is also getting more and more autumn. This solar term often meets the traditional Chinese festival, the Double Ninth Festival. Since ancient times, there has been an important custom of the Double Ninth Festival - inviting relatives and friends and looking up from afar. White dew, autumnal equinox and cold dew are the climax of the old Beijing people fighting crickets. Generally, hearing crickets means it's autumn. The weather is getting cooler, reminding people to prepare thick clothes. In the south, this is a sunny season, a good time to travel. You can enjoy flowers, eat crabs and fish. In the cold dew season, the temperature drops rapidly, and the sun can't penetrate the deep water. The fish swim to the shallow water area with higher water temperature, so there is a saying of "fishing in autumn".
