What is the meaning of the Millennium in the 24 solar terms? Brief introduction of Millennium.

1. The ancients used four seasons to match the five elements. Autumn belongs to gold, it is golden and white. Therefore, white is used to describe autumn dew, hence the name "White Dew".

2. The Millennium is the fifteenth solar term among the twenty-four solar terms, and autumn is the third solar term, indicating the end of the Qiu Meng season and the beginning of the Mid-Autumn Festival, which is an important festival reflecting the temperature changes in nature. The Millennium is the end of the application of the lunar calendar in the lunar calendar and the beginning of January. The time point is September 7th to 9th every year in Gregorian calendar, and the sun reaches longitude 165 degrees.

3. The White Dew is the solar term with the biggest temperature difference between day and night. Around a thousand years ago, the summer heat gradually disappeared, the heavens and the earth rose and spread, the weather gradually turned cold, the morning dew became thicker and thicker, and it condensed into a layer of white water droplets on the surface of grass leaves.

4. According to the observation of nature, the ancients in China divided the Millennium into three stages: "When the geese come, the mysterious birds return, and the birds are ashamed." This means that in this solar term, migratory birds such as Hongyan and Swallow fly south to avoid the cold, and hundreds of birds begin to store dried fruit food for the winter. At present, farmers are also busy harvesting crops. As the saying goes, "If you grab autumn, you will lose it." During the Bailuyuan period, local folk customs mainly included offering sacrifices to Dayu, brewing grain wine and drinking Bailuyuan tea.
