What does the Millennium solar term mean?

1, Millennium meaning: the weather is getting colder.

2. Millennium is the fifteenth solar term in the "twenty-four solar terms", which is the end of the application of the month in the dry calendar and the beginning of the unitary month. When the sun reaches 165 degrees, it will cross the Gregorian calendar on September 7-9. 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.
