The winter solstice, as an important node of China's twenty-four solar terms, is the day with the shortest day and the longest night in the area north of the earth's equator. The winter solstice is the extreme south of the sun. On this day, the height of the sun is the smallest in the northern hemisphere. On the winter solstice day, the sun shines directly on the Tropic of Capricorn, and the sun is most oblique to the northern hemisphere. The winter solstice is the turning point of the sun's southward journey. After this day, it will go "turning back". The direct sun will begin to move northward from the Tropic of Capricorn (23°26′S), and the northern hemisphere (our country is located in the northern hemisphere) will increase day by day.

         Since the earth is located near the perihelion around the winter solstice, it moves slightly faster, which causes the sun to shoot directly in the southern hemisphere for about 8 days in a year, so the winter in the northern hemisphere is slightly shorter than the summer.
