What does the Millennium in the 24 solar terms mean?

Millennium is one of the 24 solar terms, and it is also the end of the calendar application month and the beginning of January. 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.

Millennium is actually a sign that the weather is getting colder. At night, the water vapor in the air will condense into tiny water droplets, which are very densely attached to the green stems, leaves or petals of flowers and trees, showing white color. Especially after the morning sunshine, it looks more crystal clear and flawless, which is really pleasing, thus gaining the reputation of "Millennium".

"White dew" is at the turn of summer and autumn, and the temperature changes greatly from day to day. "White dew does not show", so the old, weak, sick and disabled should pay more attention to changing clothes in time to prevent catching cold.
