待你长发及腰我娶你可好待我长发及腰我立减能行
[dài nĭ zhăng fā jí yāo wŏ qŭ nĭ kĕ hăo dài wŏ zhăng fā jí yāo wŏ lì jiăn néng xíng]
When your hair reaches your waist, would you like me to marry you? If my hair reaches my waist, I could just do it immediately. The latter part adds humor by implying that growing long hair expedites the commitment to marriage, while the former conveys a sweet proposal tied to personal milestones.
