What does Du Fu mean by "looking for flowers by the river alone"?

Walking alone by the river looking for flowers (looking for flowers is to enjoy flowers)

The meaning of the whole poem is: the flowers in Huang Si's family are very lush, and the flowers and leaves cover the path; Numerous blooming flowers bent the branches. Butterflies are flying around among the flowers, as if reluctant to part. Just then, the oriole also made a beautiful cry. What a free bird.

This poem expresses the poet's love for a peaceful and quiet life and the joy of living in peace after chaos.
