Eat jiaozi or jiaozi on the winter solstice?
Most northerners will eat jiaozi, mutton or dog meat on the winter solstice to celebrate the arrival of the winter solstice. In Jiangnan, it is a traditional custom to eat jiaozi on the solstice in winter. Eating jiaozi on the solstice in winter is also called jiaozi, which means round.
Most Cantonese people will "add dishes" on the solstice in winter, and barbecue has become an indispensable traditional food on the table. Up to now, China Taiwan Province Province still has the tradition of worshipping ancestors with nine-layer cakes on the solstice in winter. Animals such as chickens and ducks are made of glutinous rice flour and steamed to worship their ancestors to show that they don't forget their ancestors.
In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice. Because of the great difference in climate in different parts of China, this winter climate is obviously late for most parts of China. The winter solstice marks the beginning of the cold season.
Solstice winter astronomical calendar:
As an important node of the 24 solar terms in China, the winter solstice has the shortest day and the longest night in the north of the equator. The winter solstice is the limit of the sun's southward travel, and the height of the sun in the northern hemisphere is the smallest on this day. On the solstice of winter, the sun shines directly on the tropic of Capricorn, and the sun is most inclined to the northern hemisphere.
The solstice in winter is the turning point of the sun's southward movement. After this day, I went back, and the direct point of the sun began to move northward from the Tropic of Capricorn (23 26' s), and the daytime in the northern hemisphere (China is located in the northern hemisphere) increased day by day.
From winter to around, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time for the sun to shine directly into the southern hemisphere is about 8 days shorter than that in the northern hemisphere, so the winter in the northern hemisphere is slightly shorter than that in summer.
