十年后你说让我穿上白婚纱十年后我说让你穿上黑礼服
[shí nián hòu nĭ shuō ràng wŏ chuān shàng bái hūn shā shí nián hòu wŏ shuō ràng nĭ chuān shàng hēi lĭ fú]
Translates to: 'ten years later, you say to let me wear a white wedding dress; ten years later, I say to let you wear a black tuxedo'. It refers to a romantic promise exchanged between couples, planning their weddings over a decade after knowing each other - showing steadfast commitment and patience in long-term relationships.
