What is the meaning of "beauty" in "looking at beauty and heaven" in "Red Cliff Fu"

Hello, landlord. My senior one student just learned Ode to the Red Wall. According to the teacher's explanation and reference books, there are many explanations for the beauty here: 1 refers to geisha, which literally means beauty. 2 refers to the author's life pursuit, ideal ambition, etc. 3 stands for king. The specific explanation is also said upstairs. I hope you can adopt it.
