What is the smallest day of the year in China?

The solstice in winter is the limit of the sun's southward travel. On this day, the height of the sun in the northern hemisphere is the smallest. On the solstice of winter, the sun shines directly on the tropic of Capricorn, and the sun is most biased towards the northern hemisphere. The solstice in winter is the turning point of the sun's southward travel. After this day, it will go back, the direct point of the sun will move northward from the tropic of Capricorn, and the days in the northern hemisphere (China is located in the northern hemisphere) will increase day by day.

In all parts of the northern hemisphere, the winter solstice has the shortest day and the longest night. The farther north, the shorter the day. Although the days from winter solstice are short, the temperature from winter solstice is not the lowest; It won't be very cold before the winter solstice, because there is still "accumulated heat" on the surface, and the real cold winter is after the winter solstice.

Extended data:

After the solar term of winter solstice, the coldest season in China will come, that is, from the winter solstice, "count nine" will begin. As the saying goes, "but the winter solstice is not cold", which means that the climate is still warm before the winter solstice, and after the winter solstice, the cold will come. Some of these proverbs and proverbs are only aimed at certain areas, or they may be based on the common climate phenomenon of that year.

In some years and regions of our country, the winter solstice is already very cold, especially in high latitudes, where the climate is even colder during the winter solstice. Therefore, we should pay attention to keep warm in winter.
