The Millennium solar terms represent this meaning.

The moral of the Millennium solar terms is that the sultry summer is basically over and the weather is getting colder and colder.

Millennium is an important festival reflecting the temperature changes in nature, basically ending the sultry summer, and it is a turning point from sultry to cool in autumn. The ancients used four seasons with five elements, and autumn was golden and golden white, so white was used to describe autumn dew. After entering the Millennium solar terms, the summer monsoon is gradually replaced by the winter monsoon, and the cold air goes south in batches, which often brings a certain range of cooling.

After a thousand years, the sky is high and the clouds are light, the wind is crisp and the temperature difference between day and night is large. At night, you will feel a little cold, and obviously feel the arrival of cool autumn. "White dew" represents the end of the summer heat. Everything grows with the cold and gradually withers and matures. In the process of changing seasons, the harvested autumn brings people health-related food and folk customs.

Influence of Millennium solar terms on crops

The meaning of the Millennium solar term is that the temperature drops and the weather begins to turn cold. The Millennium is the fifteenth of the twenty-four solar terms, and autumn is the third. When the sun revolves around the longitude 165, it means that it has entered the Millennium solar term, and it also indicates that crops are about to mature.

The Millennium solar term is coming, and you can see the dense dew on the ground and leaves in the morning. The formation of this dewdrop is mainly because the evaporated water vapor meets cold air at night. These dewdrops will look very white and crystal clear after being irradiated by the sun, so the ancients named this day Bailu.

The arrival of the Millennium solar terms represents the relief of the summer heat and the official arrival of autumn. With the increase of cold, everything began to fall slowly and mature. With the change of seasons, the harvest season brings people health-related food and folk customs.
