On the first working day after returning from the National Day holiday (October 8), we ushered in the earliest "cold" solar term among the 24 solar terms - "cold dew". With the arrival of the Cold Dew solar term, the atmosphere of late autumn in Beijing is getting stronger and stronger. Today, let's talk about the phenological phenomenon, customs and health tips of the Cold Dew solar term.

Cold dew is the 17th solar term of the 24 solar terms and the fifth solar term of autumn. It is celebrated on October 7-9 in the Gregorian calendar. The temperature of this period is lower than that of "white Dew", and the day is cold, so the name "cold Dew". As the saying goes, "cold dew, cold dew everywhere."

"The seventy-second Hou of the moon" said: "September festival, dew cold, will condense also." Cold dew is the transition from cool to cold climate, we can faintly hear the footsteps of winter. After the cold dew, autumn in the south is getting stronger, and winter is coming to the north, the rainy season is over, and the white frost is beginning to appear.

The ancients divided the cold dew into three seasons: "The first season of Hongyan guests; Two birds into the big water clam; The three chrysanthemums have yellow flowers."

Guest, guest also. He who comes first is Lord, and he who comes last is guest. Late geese, lined up in a single word or herringbone formation, continue to migrate south, looking for a place to winter.

Birds, feel the sun and out; Clam, into the water is Yin. The cold dew day is cold, the yellow sparrow has no shelter from the cold, and the clams in the sea have suddenly increased. The color pattern of the shell is similar to that of the bird, so the ancients believed that the bird turned into a clam.

The custom of climbing heights on the Double Ninth Festival has a long history. Since the Double Ninth Festival is around the Cold Dew solar term, the pleasant climate of the Cold Dew solar term is very suitable for mountaineering, and the custom of climbing the Double Ninth Festival has gradually become the custom of the Cold Dew solar term. Climbing means "higher and higher" and "longevity".

To enjoy the red leaves in Fragrant Hills during the cold dew season has long become the traditional habit of Beijing citizens and the highlight of autumn travel. The continuous cooling after the cold dew makes the maple leaves red. Autumn Manshan red leaves such as rosy brocade, picturesque.

In the south of China, the cold Dew solar term, the heat has retreated, the sun is warm, it is a good time to travel, people have to go out to enjoy flowers, eat crabs or fishing. Because of the cold dew season, the temperature drops rapidly, the sun has not been exposed to the deep water, the fish swim to the shallow water with higher water temperature, so there is a "autumn fishing edge".

Because the weather is getting cold, trees and flowers wither soon, so people call this "Ci Qing". Ninety-nine ascent, but also eat flower cake, because "high" and "cake" homophonic, so the festival pastry called "Double ninth flower cake", meaning "higher and higher".

The custom of "eating black sesame" during cold dew has a long history. As early as ancient times, there was a custom of "eating sesame with cold dew" among the people. As the saying goes: "When the golden autumn, when the dry gas", this time the dry evil gas is easy to invade the human body, if the improper care, the human body will appear a series of autumn dry symptoms. As the old saying goes, "autumn dryness, it is appropriate to eat hemp to moisten dryness", sesame has the function of moistening intestinal dryness and detoxification.

The cold dew is close to the Double Ninth Festival, when the chrysanthemum is in full bloom, in order to remove the autumn dryness, there is a custom of drinking "chrysanthemum wine" in some areas, which, together with climbing, gradually moved to the Double Ninth Festival.

Chrysanthemum wine is made from chrysanthemum, glutinous rice and wine qu. It is called "longevity wine" in ancient times. It tastes cool and sweet, and has the effects of nourishing the liver, brightening the eyes, strengthening the brain and delaying aging.

As the saying goes: "cold dew hair feet, frost catch, west wind ring, crab feet itch." At this time, the female crabs are full of eggs and yellow paste, and it is the best season to eat female crabs.

During the cold dew season, the temperature decreases and the climate is dry, and many people will have "cold dryness" symptoms such as fear of cold, dry skin, dry mouth and nose. So how can you prevent it? What is the secret of cold dew health? Let's understand!
