This old saying means that the astringency of persimmons will fade after the first frost, and the taste will be sweeter, especially the persimmons that naturally get rid of astringency on trees.

Persimmons after the first frost are not only astringent, but also sweeter than honey. That's why the first frost picked persimmons. Soft dates will not mature enough to be picked before the arrival of the beginning of winter solar term.

In fact, both kinds of fruits have excellent patience. Even if it snows, you can still see them in the country. Against the background of snow, they are no longer astringent and more delicious.
