Astronomically, the solstice in winter is the turning point of the sun's southward travel. Because the earth is located near the perihelion around the winter solstice, the running speed is slightly faster, which leads to the time when the sun shines directly into the southern hemisphere is about 8 days shorter than that in the northern hemisphere in a year, so the winter in the northern hemisphere is slightly shorter than that in summer.
