What does autumn frost mean in autumn?

Autumn dew and autumn frost are followed by winter snow, which is a little cold.

The dew in autumn and the frost in autumn come from the twenty-four solar terms in Song Dynasty. The early autumn refers to beginning of autumn, the place refers to summer, and the dew refers to the Millennium.

The second "autumn" refers to the autumnal equinox, "cold" refers to cold dew, and "first frost" is the solar term of the first frost. This proverb is the whole process of the lunar autumn. Because beginning of autumn is the beginning of autumn, the first frost is the last solar term in autumn, representing the end of autumn.
