待我长发及腰你已另寻新欢
[dài wŏ zhăng fā jí yāo nĭ yĭ lìng xún xīn huān]
'When I wait until my hair reaches my waist (indicating time passes), you have already found someone new.' This phrase conveys deep disappointment and unfulfilled love, implying that the one waiting for love never got it and was forsaken.
