Winter solstice

The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the elevation angle of the sun is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest. The solstice in winter is also a turning point for the sun to return directly to the north. After this day, it will make a "turn back", and the direct point of the sun will begin to move northward from the Tropic of Capricorn (23 26).

The days in the northern hemisphere will get longer every day. The winter solstice marks the beginning of the cold season, so people begin to count nine to calculate the cold weather (folk proverb: "The summer solstice is three Geng, and the winter solstice is nine for everyone). There is a folk proverb that "the solstice in winter is as big as a year", but during the solstice in winter, different places have different customs. Most northerners have the custom of eating jiaozi, while most southerners have the custom of eating sweets.

China's astrological culture has a long history and is profound. The twenty-four solar terms were originally formulated on the basis of changing stars. In different seasons and at different times, the Big Dipper will point in different directions, that is, "bucket handle points to the East, and the world is spring; Guide to barrel handle, it's summer in the world; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world.
