What does the peacock fir in the poem "Little Fairy Tale" mean?

Leaves. Peacock has clothes like a tree with leaves, so it is called peacock fir. "Peacocks that want to grow like trees have become peacock fir." This sentence means that peacocks envy trees with leaves and want to own peacock fir, which means that everyone envies others, but everything else envies themselves. In fact, it tells us that everyone has his own bright spot. To see your own shining point, you don't have to envy the beauty of others, but let your own shining point shine.
