你若是天空我便插翅难逃你若是深海我便削足为鱼
[nĭ ruò shì tiān kōng wŏ biàn chā chì nán táo nĭ ruò shì shēn hăi wŏ biàn xuē zú wéi yú]
Translating to 'If you were the sky, I could not fly away; if you were the deep sea, I would cut my feet to be a fish.' This expresses a deep sense of commitment, indicating that no matter where the other person is, the user will adjust to be with them.
