Introduction to the origin of the Millennium

1, Bailu is one of the twenty-four solar terms of the lunar calendar, and it is the Bailu solar term when the sun reaches 165 degrees. Millennium is the third solar term in autumn, marking the end of Qiu Meng and the beginning of Mid-Autumn Festival. Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop.

So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees.

3. Yang Qi reached its peak in the summer solstice, and the two extremes met, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew.
