待我长成长发你可愿娶我
[dài wŏ zhăng chéng zhăng fā nĭ kĕ yuàn qŭ wŏ]
Literal translation: 'When I grow long hair, will you marry me?' In traditional Chinese culture, a girl cutting or growing out her hair can sometimes indicate different stages or promises in romantic relationships; this could be about making a serious commitment when one comes of age.
