I believe everyone is familiar with the Frost Descent solar term. So, let’s take a look at what the “descent” in Frost Descent means. How is Frost Descent calculated? Introduction to Frost’s Descent dietary taboos. The ninth month of the lunar calendar brings you not only the fragrance of golden osmanthus, but also a pleasant short holiday. In the ninth month of the lunar calendar in 2020, learn about the beauty of late autumn with Shuimoxiansheng.com.What does the word "jiang" in "shuangjiang" mean?Jiang means falling. There is dew in the morning and evening starting from the White Dew solar term. The dew is cold during the Cold Dew solar term. The temperature drops during the Frost Descent solar term. The water vapor in the air condenses into hexagonal frost flowers when it is close to the ground. The frost flowers stick to plants or the ground when they are close to them, making them look like they are wrapped in icicles.Frost means the weather is getting colder and the dew condenses into frost. The ancient book “Explanation of the Twenty-Four Solar Terms” says: “When the weather becomes cold, frost falls, and the yin begins to condense.” It can be seen that “frost falls” means that the weather is gradually getting colder and frost begins to fall. In meteorology, the first frost in autumn is generally called "early frost" or "first frost", while the last frost in spring is called "late frost" or "final frost". The period from the last frost to the first frost is the frost-free period. Some people also call the early frost "chrysanthemum frost", because chrysanthemums are in full bloom at this time. Su Shi, a great writer in the Northern Song Dynasty, wrote a poem: "Thousands of trees are swept into yellow, only the lotus is fragrant alone." How is Frost Descent calculated?"Yi Zhou Shu·Zhou Yue" reads: "The middle solar terms of the three months of autumn are: End of Heat, Autumnal Equinox, and Frost Descent.""Guoyu·Zhouyuzhong" says: "Fire appears and cool wind comes first, so people should be prepared for the cold." Wei Zhao of the Wu Dynasty in the Three Kingdoms period commented: "It means that after the frost falls, the cool wind comes first, so people should be prepared for the cold." Chapter 15 of the first volume of Wei Wei's "Eastern" reads: "In terms of solar terms, it is not even the Frost Descent yet, but there have already been several frosts here." What is Frost Descent?Frost Descent is the eighteenth solar term of the twenty-four solar terms. The Dipper points to Xu; the sun's ecliptic longitude is 210°; the solar term falls on October 23-24 of the Gregorian calendar every year. Frost Descent is the last solar term in autumn and marks the transition from autumn to winter. The characteristics of the Frost Descent solar term are that the weather is colder in the morning and evening and hotter at noon, with a large temperature difference between day and night and obvious autumn dryness. Since "frost" is a manifestation of cold weather and large temperature differences between day and night, the season is named "Shuangjiang" which means "sudden drop in temperature and large temperature difference between day and night". During the Frost Descent season, all things are complete and enter the Xu period. The yang energy goes down into the earth and the yin energy begins to condense. As the saying goes, "Frost kills all the grass." After Frost, plants gradually lose their vitality and the earth becomes bleak. Frost Descent does not mean "frost falling", but rather means a sudden drop in temperature and a large temperature difference between day and night. After the Frost Descent solar term, late autumn becomes evident and cold air moves southward more frequently.Want to know your destiny?
