The mountains and rivers in my eyes are not as good as yours, and the vast stars and rivers are all turned into dust. It means: My stars are bright, the night wind is falling, and the stars and rivers in the sky are not as good as your smile. In my eyes, you are special and more beautiful than this sky full of stars.
This is a love saying adapted by modern people based on poetry. The original sentence is: The mountains and rivers in my eyes are far away in the sky, and the falling flowers and wind and rain hurt the spring even more. It is better to take pity on the person in front of you.
