What month is the lukewarm season?

The tepid solar term should be the "autumn equinox". During the "autumnal equinox" season, the temperature will drop significantly and the precipitation will decrease.

The autumnal equinox is a very important solar term among the 24 solar terms. On this day, the sun shines directly on the equator, and the word "vernal equinox" has two meanings: one is just in the middle between beginning of autumn and the first frost, and it is equally divided; The second is that it only divides the 24 hours of a day into equal lengths, and there is no extreme phenomenon of day and night in the world. After the "autumnal equinox", the position of direct sunlight will gradually move southward, and the days in the northern hemisphere will become shorter and the nights will become longer.

In fact, there are two periods in a year, May and September. These two months are neither cold nor hot, neither wet nor dry, the air is transparent, there is little rain and fog, and the human body feels very comfortable.
