What did a girl mean when she said to a boy that there were beads of tears in the ocean and moon?

This sentence came from the Tang Dynasty poet Li Bai's "Silent Night Thoughts." "Vast Ocean Bright Moon" referred to the bright moon in the sky, while "Tears Have Beads" referred to a bead hanging on the bright moon. The whole sentence meant that the bright moon in the sky was like a teardrop hanging in the sea, very beautiful. This sentence could be used in novels as a romantic, aesthetic expression or a description of beautiful things.
