The winter solstice is also a sign of the coldest period in winter, which is what people often say. There has always been a saying in China that it is "cold in March, hot in dog days". On the winter solstice, the sun shines on the tropic of Capricorn, and the northern hemisphere has the shortest day and the longest night, so the winter solstice is also called the south solstice or "south solstice". Then gradually from the tropic of Capricorn to the north, the days in the northern hemisphere are getting longer day by day, and the southern hemisphere is just the opposite.
