待你君临天下我已成沙
[dài nĭ jūn lín tiān xià wŏ yĭ chéng shā]
' Dai ni jun lin tianxia wo yicheng sha ' translates to 'When you reign over the world, I will have turned to dust.' It suggests feelings of longing and inevitability. The user feels like an insignificant entity that has lost or given up on someone, while acknowledging the other person's potential success and power.
