待你青丝馆正待我长发及腰
[dài nĭ qīng sī guăn zhèng dài wŏ zhăng fā jí yāo]
Waiting until 'you grow your black hair (which stands for youth or readiness for love)' parallels the phrase 'my long hair will reach waistlength', representing two people waiting until both feel ready to engage seriously in matters like courtship or relationship. Both look forward eagerly but patience for ideal moments.
