Custom diet of autumn equinox solar terms

The customs and diets of the solar terms in the autumn equinox are: eating autumn vegetables in the autumn equinox, sticking birds' mouths and sending autumn cows.

1. Eat autumn vegetables at the autumnal equinox: In Lingnan area, Hakkas have the custom of eating autumn vegetables. Autumn vegetable is a kind of wild amaranth, which villagers call autumn Artemisia. On the autumnal equinox, the whole village went to pick autumn vegetables. The preparation method is the same as that of spring soup, and the autumn soup is made of fish fillets. The jingle of the autumnal equinox becomes "autumn soup is dirty, the liver and intestines are washed, and the whole family is safe and healthy".

2. Sticking the bird's mouth: On the autumn equinox, Hakka farmers have a holiday according to the custom. Every family should eat dumplings. Every day, they should cook a dozen or twenty or thirty dumplings without wrapping them, and put them on the edge of the field with thin bamboo forks to stick the birds' mouths, so as not to damage crops.

3. Send autumn cows: During the autumn equinox, people send 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.
