Cultural custom of solar terms in autumnal equinox

The cultural customs of the autumnal equinox and solar terms include sending autumn cows and laying eggs.

1, send autumn cattle

When the autumnal equinox solar term comes, people send pictures of autumn cows door to door. In fact, sending autumn cattle is to print the annual lunar solar terms on red paper or yellow paper, and also print the farmer's farming pattern, which is called "Autumn Cattle Map". The people who send pictures are folk singers, who mainly say that autumn ploughing is auspicious and not against the farming season. Every time they go to a house, they improvise what 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, vertical eggs

Every autumn equinox, tens of millions of people all over the world are doing "vertical egg" experiments. How this toy, called "China Custom", became a "world game" is still difficult to verify. However, the game is simple and interesting: choose a smooth and symmetrical fresh egg that has just been born for four or five days, gently stand it up and put it on the table. Although there are many losers, there are also many winners.

Climatic characteristics of autumnal equinox

1. In autumn, the cold air in the north is constantly invading, but the power is not very strong. Autumn weather often forms in northern China, and continuous autumn rain often appears in West China. The temperature will gradually drop in autumn, but it is generally slower than in winter. Due to the difference of dry and wet conditions, there will be cold and rainy weather conditions or dry and cool weather conditions in different regions.

2. In the cold late autumn, due to the large temperature difference between day and night, the water vapor transpiration during the day will condense at night, either dew or frost. In autumn, the direct point of the sun gradually moves south from the northern hemisphere, passes through the equator after the autumnal equinox, and the sun directly shines in the southern hemisphere. Seen from the northern hemisphere, the angle of the sun gradually becomes lower, and the gap between day and night becomes smaller. At the autumnal equinox, the length of day and night is equal.
