The winter solstice is the shortest day of the year in all parts of the Northern Hemisphere. After the winter solstice, the direct sun's point gradually moves northward, the northern hemisphere begins to gradually lengthen during the day, and the noonday sun altitude gradually increases. Therefore, as the saying goes, "Eat winter solstice noodles, a long line a day." ”
From a climatic point of view, during the winter solstice, the average temperature of the northwest plateau is generally below 0 °C, and the southern region is only about 6 °C to 8 °C. In addition, the winter solstice begins to "count nine", and the winter solstice day becomes the first day of "counting nine". After the winter solstice, although the days are getting longer and the nights are getting shorter, in the short term, the days are still short and the nights are long, and the heat absorbed by the ground every day is still less than the heat lost, so the temperature does not immediately rise. Before and after the "Three-Nine", the ground has the least amount of accumulated heat, and the weather is the coldest, so it is said that "cold is in the Three-Nine".
Regarding "counting nine", the folk song goes like this, "One nine and twenty nine do not shoot, three nine, four nine walk on the ice, five nine, six nine along the river to see the willow, seven nine river open, eight nine swallows come, nine nine plus one nine plough cattle everywhere." ”
All parts of our country attach great importance to the winter solstice, and whenever the winter solstice day comes, there will be corresponding celebration activities to prepare for the next days. In the north, there are dumplings and wontons; In the south, there is a custom of eating red bean rice and eating dog meat. There is a proverb that "on the first day of October, the winter solstice arrives, and every household eats dumplings." "It is enough to prove that our country attaches great importance to the winter solstice."
