Interpretation of Nine of the Twenty-four Solar Terms

Jiujiu, also called Jiujiu in winter, is a folk method to calculate the date of warm flowers in spring and cold days in China. The number nine is counted from the date of the "winter solstice" of the twenty-four solar terms, and every nine days is counted as a "nine", and so on. Generally, March 9 is the coldest, which is the coldest time of the year. When you count to nine "nine days" (998 1 day), spring will be deep and warm, and everything will be full of vitality. It's time for spring ploughing. The number nine method is passed down from mouth to mouth among the people in our country, which has a history and lacks records. As for when it originated, there is no exact information. However, it was popular at least in the Northern and Southern Dynasties. In the Chronicle of Jingchu, Zong Yi of Liang Chao wrote: "The winter solstice is 998 1 day, which is the end of cold."

? As the saying goes, "Summer solstice is three years old, and winter solstice is nine years old." Why count "nine"? Why not count two, three, four, five, six, seven and eight? This is different from the ups and downs of Yin and Yang in China's traditional philosophy, that is, warm coming and cold going. In traditional culture, nine is the limit number, which is the largest, most and longest concept. Nine nines is eighty-one, which is the "maximum" number. Nine is the number of "Zhiyang", also called Lao Yang, and nine is the largest number. The accumulation of "Zhiyang" means that Yin Qi is decreasing day by day, and it is tired to the end for nine times, which means that the cold is getting warmer and "the spring is already deep".

The winter solstice this year is on February 22, 65438. According to the date of the winter solstice, it can be inferred that 8 1 day of the Ninth Five-Year Plan, that is, the end of March in the solar calendar (around the vernal equinox), will be the day when "peach blossoms bloom" and "spring warms bloom". Due to the vast territory of China, the climate varies greatly from place to place, not all over the country. Only parts of southern China correspond to the winter solstice "9981, Nine Peach Blossoms, Deep Spring Warm Day".

The coldest period in winter usually occurs after the winter solstice. After beginning of winter, it means that it has entered winter, but it doesn't mean that it has started to be cold. So the heat stored on the surface in the second half of the year still has some energy, so it is not very cold. There is a folk saying that it is "a spring in October". "Xiaoyangchun in October" refers to the sunny, warm and comfortable "Xiaoyangchun" weather during the winter. So early winter (Meng Dong) is generally not very cold, but with the passage of time, cold air frequently goes south and the temperature gradually drops. In winter, the so-called "March 9" and "March 9" are usually not very cold. The real cold is after the winter solstice. 65438+February 3 1 This year is about to enter the 29th, and a cold wave strikes.
