Does the solar term of heavy snow start with short days and long nights?

The solar term of heavy snow does not start from short days and long nights, but from short days and long nights in summer and long days and short nights in winter, which is the winter solstice. The winter solstice is the shortest day and the longest night in a year. After the solstice in winter, the days are long and the nights are short.

On the day of winter solstice, the sun moves to 270 degrees of the yellow meridian (winter solstice), and the position of the sun directly on the ground reaches the southernmost point of the year. The sun is almost direct to the Tropic of Capricorn (also known as the winter solstice daily line), and the sun is most biased towards the northern hemisphere. Therefore, the winter solstice is the shortest day and the longest night in the northern hemisphere. The shorter the day, the longer the night.

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 solstice in winter, the days will get longer and the nights will get shorter. The solstice in winter is a sunny day, and the days have become longer and longer since then.
