What are the characteristics and customs of the Millennium solar terms?

1, Millennium solar terms features: crisp autumn, large temperature difference between day and night throughout the year.

2. China ancient books record: "On August Festival, the yin is getting heavier and the dew is white." According to the climate law, the cool autumn wind blows all over Huaibei from north to south in the white dew season.

3. As the saying goes, "Autumn night is a thousand years, and it is cold all night." At this time, the summer monsoon is gradually replaced by the winter monsoon, with more northerly winds and cold air gradually moving south frequently. In addition, the position where the sun directly touches the ground moves south, so the sunshine time in the northern hemisphere becomes shorter and the sunshine intensity weakens. At night, it is often partly cloudy and sunny, and the ground radiation dissipates quickly, so the temperature gradually drops and the weather becomes colder and colder.

4. Millennium solar festival custom: there is a custom of "picking clear dew". In Li Shizhen's Compendium of Materia Medica in the Ming Dynasty, it was recorded: "When the autumn dew is numerous, it is gathered in one plate and fried like a pancake, which makes people not hungry." Thus, dew-clearing has become the most special "ceremony" in the Millennium. There are also folk customs such as offering sacrifices to Yu Wang, eating longan, drinking Bailu tea, and drinking Bailu rice wine. In some areas, clean food such as lotus seeds and lilies will be eaten before and after Bailu.
