is the coldest day: not during the winter solstice, the earth is the perihelion, which is the farthest point where the sun moves south. On the winter solstice, the northern hemisphere has the lowest solar height and the shortest day, but the winter solstice is not the coldest day. Because when the direct point of the sun moves to the southern hemisphere, the temperature in the northern hemisphere begins to decrease a little, the heat dissipation continues almost unchanged, and the weather will become colder and colder. Therefore, although the winter solstice is the time when the solar radiation energy is the lowest, the ground, especially the water body, can store huge energy as a buffer medium, so the temperature change needs an accumulation process. The cooling in the northern hemisphere is a continuous and slow process. On the winter solstice, when the sun shines directly on the Tropic of cancer, the earth's temperature is still decreasing with that downward trend. The coldest solar terms in a year are before and after the minor cold solar terms and severe cold solar terms half a month later.

what is the earliest origin of the ancient traditional festival of the Chinese nation? Whether it is a big festival or a small festival, its origin is either from the astronomical phenology, or from the ancestors choosing an auspicious day to sacrifice the gods and ancestors of heaven and earth to thank the gods and ancestors for their kindness. Most traditional festivals are regarded as the "origin" by a legend of a figure on the attached meeting, but the actual investigation shows that these statements are far later than the birth of the festival and are constructed by future generations. In ancient times, there was a saying that "one Yang at the winter solstice", that is, from the day of the winter solstice, Yang began to rise slowly. As modern poetry says: when winter comes, can spring be far behind? In ancient times, people who drifted in other places had to go home for the winter festival at this time, which is called "end of year destination". The book of the later Han Dynasty records that "before and after the winter solstice, a gentleman settled down and became calm, all officials did nothing, did not listen to politics, and chose an auspicious hour to save trouble." in the folk, people visited relatives and friends and presented them with delicious food.

winter solstice is also a traditional sacrificial day. It is said that after the Song Dynasty, the winter solstice gradually became a festival to sacrifice ancestors and gods. During the Tang and Song Dynasties, the winter solstice was the day to worship heaven and ancestors. The emperor wanted to hold a great ceremony to worship heaven in the suburbs, and the people wanted to worship their parents and elders. On the winter solstice of the Ming and Qing Dynasties, the emperor held a grand ceremony to worship the sky, which is called "the suburban sky of the winter solstice". During this period, people also have ancestor worship, family dinner and other customs. Therefore, the winter solstice is called "Xiaonian". The winter solstice as a festival originated in the Han Dynasty and flourished in the Tang and Song dynasties. The first month of the Zhou calendar is November of the summer calendar. Therefore, the first month of the Zhou Dynasty is equal to November of the Gregorian calendar, so there is no difference between new year worship and winter celebration. It was not until Emperor Wu of the Han Dynasty adopted the summer calendar that he separated the first month from the winter solstice. It can also be said that the simple "Winter Solstice Festival" has existed since the Han Dynasty and flourished in the Tang and Song dynasties.
