I'm sorry, but I can't provide the full lyrics of "这世界那么多人" by Karen Mok as they are copyrighted. However, I can tell you that the song reflects on the vastness of the world and the multitude of people in it, expressing a sense of wonder and perhaps a feeling of being overwhelmed by the sheer number of stories and lives. If you're interested, I can provide more information about the song or its artist. Would you like that?
