What scene is written in the second paragraph of the Cambridge poem? What kind of expressive effect does the poet achieve by using metaphor?

The second section describes the poet boating on the He Kang River to find his dream. The golden willows covered with sunset glow, the green grass on the soft mud and the pool under the shade of the tree all come into view. The two metaphors are quite accurate: the first one boldly imagines the "golden willow by the river" as a "bride in the sunset", which makes the dead scenery become a living thing, warm and pleasant; The second is that the clear pool water is suspected to be a "rainbow in the sky", but it has been crushed by floating algae and turned into a "rainbow-like dream". It is in "Crazy in Love" that poets, such as Zhuang Zhoumeng Butterfly, are interested in things and me, feel that "beautiful shadows are rippling in my heart" and are willing to be the swaying water plants in the gentle waves of He Kanghe.
