What does it mean that the frost tree has broken its branches and broken its cloves?

"Frost trees are empty, and cloves are broken" means: "When autumn comes, the trees are covered with clear frost and all the flowers are gone, leaving only empty branches, and my heart is full of sorrow, just like the buds of lilacs". From Feng Yansi's Drunken Flowers, Stars and Moon Before Independence.

The poem "Frost trees are all empty, and cloves are broken" comes from the ancient poem "Drunken Flowers, Stars and the Moon Before Independence", written by the ancient poet Feng Yansi, which means: "When autumn comes, the trees are covered with frost, and all the flowers are gone, leaving only empty branches, and my heart is full of sorrow, like the buds of lilacs."

Its contents are as follows:

Before the independent stage, the star is full of moon, and

The curtain is bright.

the frost tree is empty, and

It's cold in the middle of the night,

If you hate it, you'll never rest,

If you want to break down.

Two jade chopsticks are hung by the monarch.
