The custom of solar terms in autumn equinox

The main features are as follows: the position of direct sunlight continues to move from the equator to the southern hemisphere, and the phenomenon that the days are shorter and the nights are longer in the northern hemisphere will become more and more obvious, and the days will gradually become shorter and the nights will gradually become longer (until the nights are longer and shorter in winter solstice); The temperature difference between day and night will gradually increase, and the amplitude will be higher than 10℃. The temperature drops day by day, getting colder every day, and gradually entering the late autumn season. The situation in the southern hemisphere is just the opposite.

The average daily temperature in autumn is below 22℃. At the autumnal equinox, the Yangtze River basin and its vast northern area have entered autumn, and the daily average temperature has dropped below 22℃. The cold air mass in the north began to have some influence. In most areas, the rainy season has just ended, with a cool breeze blowing gently, the sky is high and the clouds are light in Wan Liqing, the air is crisp in autumn, the sweet-scented osmanthus is fragrant, the crab is fat and the chrysanthemum is yellow, and the autumn equinox is a beautiful and pleasant season.

There is a lot of geothermal loss and the temperature drops rapidly. After the autumnal equinox, the direct sunlight moved to the southern hemisphere, and the northern hemisphere got less and less solar radiation, but the ground lost more heat and the temperature dropped significantly. Agricultural proverbs say: "An autumn rain is a cold", "The white dew is divided into autumn nights, and one night is cold". "In August, the wild goose gate opens, and the foot of the wild goose is frosty." It is not surprising that the temperature in Northeast China drops early and frost appears at the autumnal equinox.

Customs:

1. Send the autumn cattle, the autumn equinox is coming. There will be autumn cows coming to your door. The picture is printed with red paper or yellow paper on the lunar solar terms all the year round, and also printed with farmers' ploughing patterns, which is called "Autumn Cattle Map". The pictures are all folk singers, mainly talking about good luck in autumn ploughing that does not violate the farming season. Every time they go to a house, they say whatever they see until the owner is happy to give money. Although the words spoken are casual, every sentence rhymes beautifully. Commonly known as "Autumn", Qiu Ren is called "Qiu Guan".

2. Stick the sparrow's mouth. On the autumnal equinox, farmers have a holiday according to the custom. Every family should eat glutinous rice balls, and a dozen or twenty or thirty glutinous rice balls that don't need wrapping should be cooked, and placed on the edge of the outdoor field with a thin bamboo fork, which is called sticking the bird's mouth to avoid being harmed by birds. Of course, it is only the farmers' beautiful imagination and desire to stick dumplings on sparrows' mouths, but it also illustrates the truth that dumplings are sticky, difficult to digest and should not be eaten more.

3, flying kites, the autumnal equinox is still a good time for children to fly kites. Especially at the autumnal equinox. Even adults are involved. Kites are divided into Wang Zi Kite, Silver Carp Kite, Myxomoth Kite, Leigong Kite and Moon Light Kite. The biggest kite is two meters high, and the smallest one is two or three feet. There are kites on the market, many of which are smaller than others' and suitable for children to play with, but most of them are posted by themselves, and the bigger ones have to compete with each other to see which one flies high.
