你若是深海我原削足为鱼
[nĭ ruò shì shēn hăi wŏ yuán xuē zú wéi yú]
It is inspired by an ancient story where love surpasses all barriers. It means 'If you were the deep sea, I would rather become a fish just to be with you'. It shows dedication and the willingness to go to extremes to achieve unity or connection with another.
