The winter solstice is commonly known as "Winter Festival", "Dragon Solstice Festival" and "Asian New Year Festival". As early as 2500 years ago, during the Spring and Autumn Period, China observed the sun with soil gauge and determined the winter solstice. This is the earliest of the 24 solar systems. The time is between June 65438+February 2 1 and 23rd every year. This is the shortest day and the longest night in the northern hemisphere all year round.
From the climate point of view, during the winter solstice, the average temperature in the northwest plateau is generally below 0℃, while the average temperature in the southern region is only 6 ~ 8℃.

The origin of the festival:
The phrase "the solstice in winter is as big as a year" is widely circulated among the people. Also known as "off-year". First of all, it shows that the year is coming, and the New Year is in the winter solstice. Therefore, the ancients believed that the winter solstice was as important as the New Year. Secondly, it means the importance of the winter solstice. The solstice in winter has two meanings: nature and humanity. It is not only a natural sunspot, but also a traditional festival of ancestors.
During the winter solstice, due to the solar term "the sun shines on the winter solstice and the sun shines on the heavens and the earth", the ancients thought that from the winter solstice, the sun shines on the heavens and the earth, so the ancients thought that the winter solstice was an auspicious day, and the gods and ancestors were sacrificed in the winter solstice, forming a festival custom.
