What does the winter solstice handwritten newspaper write?

On the day of winter solstice, the sun moves to 270 degrees of the yellow meridian (winter solstice), and the position of the sun directly on the ground reaches the southernmost point of the year. The sun is almost direct to the Tropic of Capricorn (also known as the winter solstice daily line), and the sun is most biased towards the northern hemisphere. Therefore, in all parts of the northern hemisphere, the winter solstice is the shortest day in a year, and the farther north, the shorter the day.

North of the Arctic Circle, the sun is below the horizon all day, which is the widest day of the year in the northern hemisphere. For all parts of the northern hemisphere, the winter solstice is also the day with the lowest sun height at noon all year round. As far as Beijing is concerned, the daytime from winter to sunrise is only 9 hours and 20 minutes, and the height of the sun at noon is only 26 42'.

During the winter solstice, the northern hemisphere gets the least solar radiation, about 50% less than the southern hemisphere. The winter solstice is a sunny day, and the new year begins. "Collection of Classics" states that "summer is the end of the autumnal equinox, spring is the winter solstice", and the winter solstice festival is the first sound of spring. After the winter solstice, the stars in the night sky are completely replaced by the stars in winter. From today, they will enter the ninth. At this time, the southern hemisphere is in a hot summer.

The traditional diet from solstice to winter?

In the north of China, people eat jiaozi every year from the winter solstice of the lunar calendar, and jiaozi is an indispensable holiday feast for the rich and the poor. As the saying goes: "On October 1st, when the solstice of winter comes, every family eats jiaozi." This custom was left in memory of Zhang Zhongjing, a "medical sage", who gave up medicine from the winter solstice.

The coldest day of the year

Copying nine days from winter solstice is a method for ancient people to calculate solar terms. From the solstice of winter every year, take this day as one, start counting nine, the ninth day is nineteen, the next nine days are twenty-nine, and so on, until the end of ninety-nine days, spring will come.

The number nine from winter to the sun is also called "Winter 99", which is often said to be cold. The folk number nine song "1929" intervenes in your arms; 3949, frozen pigs and frozen dogs; 5969, look at the willows by the river; 79 ducks and 89 geese; 7963, pedestrian clothes list; In 998 1 year, the elderly cultivated land in Tian Zhongli.
