Is there a custom of eating jiaozi in the north on the solstice of winter?

Most northerners eat jiaozi on the solstice in winter, and some people also eat mutton and dog meat. It is said that jiaozi originated from the ancient "Jiaozi" and was invented by Zhang Zhongjing, a medical sage. After more than a thousand years of development, it has gradually become a special food that northerners often eat. The common jiaozi is salty, and the main fillings are pork, mushrooms, three delicacies, leeks and pork.

Jiaozi can be steamed or boiled. We call steamed dumplings "steamed dumplings" and boiled jiaozi "jiaozi". There is a proverb in the north called "jiaozi in winter and noodles in summer", which shows their enthusiasm for eating jiaozi in winter.

Extended data:

Time of solar term from winter to solar term.

Pointing to the bucket, the longitude of the sun is 270, which is the solstice in winter. The first month is the first month, November is the second month, and the winter solstice is the 22nd of the 24 solar terms. The winter solstice usually falls on 65438+February 2 1 or 65438+February 22 in the Gregorian calendar. For example, the specific time of winter solstice in 2020: 65438+February 2 1, 18: 02.

Note: The average time method (used before 1645) does not consider the uneven speed of the sun moving on the ecliptic, which is different from the constant gas method (used since 1645), and the specific intersection time of each solar term is also different.

Astronomically, the "winter solstice" is the turning point of the sun's southward movement. From winter to around, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time of direct sunlight in the southern hemisphere is about 8 days shorter than that in the northern hemisphere in a year, so the winter in the northern hemisphere is slightly shorter than that in summer.
