What does this short poem mean?

The poet wrote the pride of Bai Lianhua through the feelings of sunflower. Sunflowers have different feelings before and after the lotus leaves the water. Especially after writing that the white lotus came out of the water, sunflower felt ashamed and was impressed by the pride of the white lotus. This anthropomorphic description distinguishes two different personalities, from which we can see the poet's value orientation.

Flowers are real in essence, but the poet expresses the philosophy in the rational world through the conceptualization of flowers, which makes flowers have a rational color.
