What rhetorical devices did Du Mu use to describe the scenery of Jinguyuan Garden?

This is a poem by Du Mu, which uses the scenery to express emotion and the ancient to satirize the present. The original text is: Jinguyuan's prosperity is scattered, and the water is ruthless. The birds groaned, and night came with the sound of the east wind; Falling flowers are as beautiful as green beads falling from upstairs. 2. Poetry translation: The prosperous past has vanished like incense dust; The running water is ruthless, and the weeds greet the spring with green every year. The bird cried sadly, and in the evening, it came with the sound of the east wind; There are many fallen flowers, just like the green pearl beauty who fell from the building in Shi Chong. 3. Answer the question: This is an impromptu poem. The poet passed by the ruins of Jinguyuan, a rich man in the Western Jin Dynasty, hanging his ancient feelings. The previous sentence says that the prosperity of Jinguyuan in the past is gone forever; The second sentence says that although the personnel are absent, the scenery is different; Three or four sentences are emotional, and listening to birds sounds like sadness; Seeing the falling flowers on the ground, I thought of Shi Chong's concubine, Lvzhu, who committed suicide by jumping off a building. Every sentence is about scenery, and every level must be in-depth. There are people in the scene and there are feelings in the scene. Writing about scenery is meaningful, lyrical and sad.
