Is it white dew fever in the twenty-four solar terms?

Millennium doesn't mean that the weather will get hot. Millennium is the dew on the grass in the morning, but it is actually a symbol of cold weather.

The white dew is the fifteenth solar term in the twenty-four solar terms of the lunar calendar, and it is the white dew when the sun reaches 165 degrees. This solar term marks the end of the Qiu Meng season and the beginning of the Mid-Autumn Festival, which is an important festival reflecting the temperature changes in nature.

At this time, the weather is getting colder, the sky is high and the clouds are light, the air is cool, and the temperature difference between morning and evening is large. In the early morning of this period, there will be a lot of dew on the ground and leaves, so the ancients used the five elements and four seasons, autumn belongs to gold, metal white and white to describe autumn dew, so this festival was named Bailu.

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. Yang Qi reached its peak in the summer solstice, and Yin Qi also rose at this time.
