The beautiful woman accompanies the solitary lamp means that the beautiful woman accompanies the solitary lamp.
The idiom "A beautiful woman is accompanied by a solitary lamp" comes from a poem by Du Fu, a poet of the Tang Dynasty, "A beautiful woman rolls up a bead curtain and sits deeply with her eyebrows furrowed, but when she sees wet tears, she doesn't know who she hates." The "beautiful woman" in the idiom refers to a beautiful woman, while the "solitary lamp" refers to the light that lights up when you are alone. The entire idiom uses the word "companion" to vividly describe the scene of a beautiful woman alone at night with only a solitary lamp for company. This idiom is often used to describe a lonely and desolate atmosphere, or to express someone's inner isolation and loneliness. It is not only a description of the actual scene, but also contains the poet's emotion about the life situation and the regret that beautiful things cannot be cherished and cared for as they should be. In literary works, "beautiful lady accompanied by a solitary lamp" is often used to exaggerate the atmosphere and increase the emotional depth of the story, allowing readers to empathize with the inner world of the characters.
