陪你生老病死如何伴我携手白头可好
[péi nĭ shēng lăo bìng sĭ rú hé bàn wŏ xié shŏu bái tóu kĕ hăo]
Loosely translated, it asks 'Would you accompany me through the trials of birth, illness, aging, and eventually death? Could you take my hand and live till our hair turns white together?'; essentially it questions whether another would stand by their side throughout the entirety of one's lifespan - a proposal or hope for long-lasting companionship.
