The winter solstice is the year with the shortest day and the longest night in the northern hemisphere. After the solstice in winter, the days will get longer day by day. The ancients said this about the winter solstice: As soon as the cathode arrived, the yang began to grow, the sun went south, the day was short and the shadow was long, so it was called "the winter solstice". After the winter solstice, the climate everywhere has entered the coldest stage, which is what people often say. There is a folk saying in China that "it's cold in March and hot in dog days".
