What does the girl's fortune-telling mean in Peony in Autumn Garden?

The ancient book says, "There are stars in the sky and stars in the sea. Although peony in autumn garden is talented, it is out of date."

Peony, with its elegant and magnificent flowers, is known as "the beauty of the country" and "the king of flowers", and the reputation of "the flower of peony is the best in the world" is also spread all over the world. So it is used to describe people's talents.

Peony is in full bloom in spring, but it can't show its beauty in autumn. Therefore, Peony in Autumn Garden describes a person who is untimely and talented.
