White dew and rain.

Old people say that the once-in-a-thousand-year rain means that the weather is good this year, which is a summary of nature for many years.

As the saying goes, "Rain in the Millennium is autumn harvest", which means it rains in the Millennium. This year is a good year, and the grain will be bumper. The Millennium is the season of grain harvest. At this time, sorghum, soybeans, corn, peanuts and other food crops have matured and entered the harvest period.

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".

The historical origin of the Millennium:

Twenty-four solar terms are special festivals in the calendar to express natural rhythm changes and establish "December construction". Four years old, three months in spring, summer, autumn and winter, two solar terms each month, each solar term has its own unique meaning. The Millennium is the fifteenth of the twenty-four solar terms, which marks the end of the Qiu Meng season and the beginning of the Mid-Autumn Festival, and is an important festival reflecting the temperature changes in nature.

The almanac says that "the bucket refers to the dew, the yin is getting heavier, and the mausoleum is the dew, hence the name". Entering the Millennium, the most obvious feeling is that the temperature difference between day and night is widening, and you will feel a little cold at night. Although the summer heat may not leave at once, the sultry feeling will gradually fade away, adding a coolness of autumn in the morning and evening. As the weather turns cold, the sun is still hot during the day, and the sun returns to the mountains, and the temperature drops rapidly.
