The lyrics of a song are "Some people say that he signed in Shanghai". What song is it? It seems to belong to Lan Yu.

Song: Love Cocoon Singer: Lan Yu Album: The Last Tender Lyrics: Silly Wind Lan Yu-Love Cocoon My tears turned into threads, my broken heart turned into cocoons, and everything was sealed, waiting for one day. I broke the cocoon into a disc, and the brand you wanted was engraved with an ancient oath. Some people say that this is a signal that indicates a better tomorrow. After all these years, has the oath become a joke? The love you gave gradually became scarce, my heart began to spread, and I couldn't fall in love. Goodbye is doomed to never meet each other, and promises are doomed to never be fulfilled. My tears turned into snow, my broken feelings turned into cocoons, all my thoughts froze, and I began to hibernate on the day I broke up.
