我愿为你画地为牢我愿为你封心锁国
[wŏ yuàn wéi nĭ huà dì wéi láo wŏ yuàn wéi nĭ fēng xīn suŏ guó]
In translation, it means: 'I am willing to imprison myself for you; I am willing to shut my heart completely for you'. It suggests unconditional love to such an extent where the person would cut off all others and focus entirely on one individual, even sacrificing freedom and social engagement.
