待我长发及腰少年娶我好么
[dài wŏ zhăng fā jí yāo shăo nián qŭ wŏ hăo me]
Literally means 'when my hair grows to my waist, will you marry me?' It's a romantic expression that combines traditional notions of waiting and maturation with hope and expectation from someone's lover. It’s a poetic appeal expressing wishful thinking about love.
