我看不見影子盤旋你的笑臉銷聲匿迹
[wŏ kàn bù jiàn yĭng zi pán xuán nĭ de xiào liăn xiāo shēng nì jī]
Translating loosely to 'I cannot see the shadow circling your smiling face which vanished without a trace,' it implies deep longing for someone whose presence is no longer felt, emphasizing feelings of loneliness and helplessness.
