What is the solar term for the year of Asia?

Subage refers to the winter solstice. Winter solstice is an important solar term among the 24 solar terms, and it is also one of the eight seasons. The solstice in winter also marks the rebirth of the sun and the round-trip movement of the sun into a new cycle. In ancient times, there was a saying that the winter solstice was as big as a year. The solstice in winter, also known as "southern solstice, winter festival and sub-year-old", has both natural and humanistic connotations. On the winter solstice, the sun goes south to the extreme, and the sun shines directly on the tropic of Capricorn. Since the winter solstice, the direct point of the sun has returned to the north. The solstice in winter is the turning point of "going south to north". Since then, the height of the sun has risen and the days have increased day by day.

In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice.

Because of the huge climate difference in China, this climatic winter is obviously late for most parts of China. The winter solstice marks the beginning of the cold season.

"Han Shu" said: "The sun shines on the winter solstice, and you are long, so congratulations." After the winter solstice, the days get longer and the sun rises, which is the beginning of a round-trip cycle at the direct point of the sun. This is an auspicious day and should be celebrated.
