Nop Chenyuelong Piano Sheet Verified -

Another angle: "Nop" might be part of the piece's title. Sometimes, sheet music titles include words like "No." (abbreviation for "Number") which could be miswritten as "Nop". So maybe "Nop Chenyuelong" is "No. Chenyuelong"? Or perhaps it's a misheard "Op." which stands for "Opus" in music, indicating the work's number in a composer's catalog. So "Op. Chenyuelong" could mean Opus number for a piece by Chenyuelong. That would make sense if the user is looking for the official opus number sheet music.
