A brief introduction to the origin of eating jiaozi in winter, 20 words

Jiaozi, formerly known as Joule, was first invented by Zhang Zhongjing, a doctor in China.

Zhang Zhongjing is from Gedong, Nanyang. In the Eastern Han Dynasty, he served as a magistrate in Changsha, visiting doctors and practicing medicine in the lobby. Later, he resolutely resigned and went back to his hometown to treat his neighbors. When he got home, it was already winter. He saw that the villagers on both sides of the Baihe River were sallow and emaciated, hungry and cold, and many people's ears were frozen.

He asked his disciples to build a medical shed and a cauldron in Dongguan, Nanyang, and to give up "Quhan Joule Decoction" to treat chilblain on the day of winter solstice. He boiled mutton, pepper and some herbs for dispelling cold in a pot, then took out mutton and medicine and chopped them up, making ear-shaped dumplings with bread. After cooking, he distributed two horns and a big bowl of broth to everyone who came to ask for medicine.

People ate "Joule" and drank "Quhan Decoction", and they were all hot, their ears were hot, and their frostbitten ears were cured. Later generations learned the appearance of Joule and packaged it into food, also called "jiaozi" or "flat food". When you eat jiaozi on the solstice in winter, you will never forget the kindness of Zhang Zhongjing, a "medical sage", in "Quhan Joule Decoction".

Climatic characteristics of solar terms in winter solstice

Astronomy regards the winter solstice as the beginning of winter, which is obviously late for most parts of China. There is a cloud in the poem: "The northwest wind hits a hundred herbs and declines, and the cold rises several times a day. The daytime is the shortest, but I see Jin Mei blooming. " (Heshui Zuo) In all parts of the northern hemisphere, the winter solstice is the shortest day in a year.

After the winter solstice, the direct point of the sun gradually moved northward, the days in the northern hemisphere began to get longer and the height of the sun gradually increased at noon. Therefore, there is a saying, "Eating noodles on the solstice in winter will make the day longer."

Climatically, during the winter solstice, the average temperature in the northwest plateau is generally below 0℃, and the southern region is only about 6℃ to 8℃. In addition, the winter solstice begins to count to nine, and the winter solstice becomes the first day to count to nine.

As for "Counting Nine", a folk song goes like this: "Don't do it in September, walk on the ice in March and April, see willows along the river in May and June, open the river in July and September, eight or nine swallows come, and ninety-nine cows walk everywhere." However, in the southwest low-altitude valley area, even in the coldest local165438+ in early October, the average temperature is still above 10℃. It can be said that autumn goes and spring comes, and there is no winter all year round.
