What does the winter solstice solar term mean?

The winter solstice solar term means the arrival of cold winter.

The winter solstice is the 22nd solar term among the traditional 24 solar terms in China, and it is also the third solar term in winter.

The word winter solstice means winter solstice, which means that winter has reached the extreme, that is, the cold weather has reached the coldest moment.

However, from another perspective, the solstice of winter also means the coming of spring, because from this day on, the sunshine time increases day by day and the temperature rises gradually. The origin of solar terms in solstice winter can be traced back to ancient farming civilization.

By observing the climate change and phenology in nature, the ancients found that the winter solstice is the moment when the direct point of the sun reaches the tropic of Capricorn, and it is also the shortest day and the longest night in the northern hemisphere. Therefore, the winter solstice has become an important reference for agricultural production and is of great significance for arranging agricultural activities.

Characteristics of solar terms in winter on solstice:

1, the shortest sunshine time: from winter to the sun, the sun shines directly on the tropic of Capricorn, and the sunshine time in the northern hemisphere reaches the shortest day of the year. This means that from this day on, the days will be longer and the nights will be shorter.

Minimum temperature: winter solstice is the beginning of winter, and the temperature will drop sharply, reaching the lowest point of the year. This is because although the direct point of the sun begins to move northward, the solar radiation absorbed by the ground is still less than the heat lost, so the gas temperature will continue to drop in the short term.

3. The birth of Yang: The solstice in winter is an important node in the transformation of Yin and Yang. The ancients believed that being born in the sun from the solstice of winter meant that the yang began to grow, and the days would gradually become longer, injecting vitality into the growth and hope of the new year.

4. Rich culture and customs: The winter solstice is not only the node of climate change, but also an important part of China traditional culture. On this day, people will have customs and habits such as offering sacrifices to ancestors, family reunion and eating special food to express their respect for life and expectations for the future.
