Today, we welcome the fifteenth solar term of the twenty-four solar terms – White Dew. White dew usually falls between September 7th and 9th in the Gregorian calendar each year, when the sun reaches 165 degrees longitude, marking the end of the Meng autumn season and the beginning of the mid autumn season.
Why is Bai Lu called “Bai Lu”?
In ancient times, the four seasons corresponded to the five elements. Autumn belongs to the metal element, which is golden and white. Therefore, “white” is used to describe autumn dew. In the “Collection and Explanation of the Seventy Two Seasons of the Moon”, it is recorded that “water and soil moisture condense into dew, autumn belongs to gold, golden and white, the color of dew is white, and the air begins to cool.” At this time, the weather gradually cools down, the temperature difference between day and night increases significantly, the sunshine is still warm during the day, and the temperature drops rapidly at night. The water vapor in the air condenses into small water droplets, which adhere to the branches and leaves of flowers and plants, and become crystal clear and white under the morning sunlight, hence the name “White Dew”.
White Dew Customs: Collecting Clear Dew, Drinking White Dew Tea, Brewing White Dew Wine
During the White Dew season, there is a folk custom of “collecting and clearing dew”. The ancients believed that the dew of White Dew was the purest. In the Compendium of Materia Medica, it is recorded that “when autumn dew is abundant, it is collected on a plate and fried like malt, which can keep people from hunger for a long time”. White dew tea “is also a unique charm of this season. The tea trees are tempered in the scorching heat, and the tea leaves picked at this time are not bitter or astringent, sweet and clear. The brewing tradition of “Bailu wine” is still preserved in the Chenzhou area of Hunan Province. The rice wine made from new rice is a local intangible cultural heritage technique that has been passed down for thousands of years. There is a saying in agriculture: “White dew is enchanting and enchanting, and the autumn equinox is full of rice.” If there is dew before and after the white dew, it indicates a good harvest of late rice.
White dew health preservation: prevent autumn dryness, do not expose the body, suitable for moisturizing and nourishing
During the White Dew season, the climate is mainly characterized by “autumn dryness”, and the human body is prone to discomfort such as dry mouth and throat, and dry skin. Health preservation should follow the principle of “moistening dryness first, nourishing but not greasy”, and eat more yin nourishing and lung nourishing products such as tremella, lily, snow pear, honey, etc. There is a saying in folk culture that “white dew should not be exposed”, which means that at this time, there is a large temperature difference between day and night, and it is not advisable to go shirtless. Especially in the morning and evening, attention should be paid to keeping warm to avoid the invasion of cold pathogens.
