The whole poem is as follows:
Wisteria hangs clouds, and flowers are suitable for spring.
The secret-leaved songbird is a kind of fragrant and romantic beauty.
Moral: wisteria is hanging on a big tree, and the vines in spring are so beautiful. Birds are singing in the dense leaves, and beauty misses its fragrance.

The poet vividly depicts wisteria, flowers, dense leaves, fragrant wind and beautiful scenery, which shows the poet's high generalization and artistic expression.
