What does the solstice mean in winter?

The winter solstice has the following meanings:

The solstice of winter means that the cold winter is coming. In winter solstice, the longitude of the sun is 270 degrees. On the solstice of winter, the sun shines almost directly on the tropic of Capricorn. Our northern hemisphere has the shortest day and the longest night, and it has begun to enter several cold days. Astronomy stipulates that this day is the beginning of winter in the northern hemisphere. After the winter solstice, the direct sunlight gradually moved northward, and the days in the northern hemisphere gradually became longer. As the proverb goes, eating noodles on the solstice in winter will make the day longer.

The winter solstice is a very important solar term, and it is also a traditional festival in China's lunar calendar. Up to now, there are still many places where the winter solstice festival is held. The winter solstice is usually called the winter festival, the long solstice festival and the sub-year festival. As early as 2500 years ago, during the Spring and Autumn Period, China had determined the winter solstice by observing the sun through the soil return, which was the earliest of the 24 solar terms. The time is between February 22nd and 23rd of Gregorian calendar 12.

After the winter solstice, the climate in all parts of China will enter the coldest stage, which is often said to be cold in September and September. The so-called nine refers to nine days as a unit from the winter solstice, which is the so-called nine. After nine nines, it is exactly 8 1 day, which means nine or nine. Count from nine to nine, and the cold winter will turn into warm spring. The ancients believed that the winter solstice was the key solar term for the transformation of yin and yang.

Nine is the largest positive number in numbers. Keep counting 19, 29 and so on. It means that the yin in winter gradually decreases, and the yang gradually picks up until nine tired. From the meteorological point of view, there will be a cold wave every nine days, and it often happens in the last day or two of the first nine; Psychologically speaking, nine is homophonic with long, which means that winter is long, and I hope spring will come early.
