若你是海我愿削足为鱼
[ruò nĭ shì hăi wŏ yuàn xuē zú wéi yú]
Translates as 'If you are the sea, I'm willing to become a fish that cuts off its own legs to fit in'. It poetically implies that for love (metaphorically speaking), the person would go to any length to transform themselves just to be together with another, suggesting a strong devotion and adaptability even if painful.
