What are the images of grass, running water, cuckoo and wild goose in ancient poetry? There must be poetry.

Where there is much grass in the sea, grass is a woman!

Falling flowers are intentional, running water is ruthless, running water is ruthless!

Yan Honghuabi, cuckoo crying blood cuckoo stands for sadness, probably a lovelorn person!

The wild goose never answered me. The rivers and lakes are flooded with rain, and it is estimated that she is a lovesick person!
