The autumnal equinox is here, and the days and nights are long, with cinnamon fragrance.

The autumnal equinox is a "just right" solar term.

"The Story of the Spring and Autumn Period" wrote, "The autumn equinox is half cloudy and half sunny, so it is hot and cold day and night."

At this time, the time of day and night is equal, the temperature is the most pleasant, and autumn is just right. At this point, it has been fully extended. Nature has given us the premise of happiness.
