待我长发及腰时娶我可好待你长发及腰时嫁我可好
[dài wŏ zhăng fā jí yāo shí qŭ wŏ kĕ hăo dài nĭ zhăng fā jí yāo shí jià wŏ kĕ hăo]
The phrase is romantic, implying a promise or plea to be married when the user’s lover’s hair grows long enough to reach the waist; this reflects an old Chinese tradition associated with readiness for marriage as women used to keep longer hair.
