Millennium is 15 of the 24 solar terms, and the third solar term in autumn is the end of the lunar application and the beginning of the unitary month in the dry calendar. Fighting fingers; The sun reaches longitude 165 degrees; Gregorian calendar September 7-9. "White dew" is an important solar term reflecting the growth of cold in nature. As the weather turns cold, it is sunny and hot during the day, but the temperature drops quickly after evening, and the temperature difference between day and night is large.

During the white dew, the summer monsoon is gradually replaced by the winter monsoon, and the cold air changes from defense to attack. In addition, when the direct point of the sun moves south, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation dissipates heat quickly, so the cooling speed gradually accelerates. The Millennium basically ended the sultry summer, and the weather gradually turned cold, and the cold gave birth to dew condensation.

The ancients used four seasons to match five elements. Autumn belongs to gold, gold and white alternate with each other, and autumn dew is described in white, hence the name "White Dew". According to the standard of "average climate temperature" put forward by modern scholar Zhang Baokun, the average climate temperature is 10-22℃ in spring or autumn. According to this standard, from the beginning of the Millennium solar term, all localities began to enter autumn one after another.

As the saying goes,' the Millennium reveals itself'. It is said that the weather is bad enough to give clothes and ears. "It is intended to remind people that it is still hot during the day, but it is already cold in the morning and evening, and it is easy to catch cold when going shirtless. In addition, we should prevent autumn dryness at this time. According to the observation of nature, the ancients in China divided the Millennium into three stages: "When the geese came, the mysterious birds returned, and the birds raised their shame. "

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. In the early autumn of the Millennium season, crops gradually mature and enter the stage of timely harvesting, drying and warehousing; There is an old saying that "crops are generally harvested in early autumn, and cutting, transporting and rolling should not be slack", otherwise there is a risk of "grabbing autumn and grabbing autumn, or losing money if you don't grab it";

Therefore, in the Millennium, while managing autumn vegetables, we should also pay attention to the maturity of early autumn crops in time, and harvest mature crops to dry at home and return to the warehouse in time. During the Bailuyuan period, local folk customs mainly included offering sacrifices to Dayu, brewing grain wine and drinking Bailuyuan tea.
