当我心跳停止我才放弃你
[dāng wŏ xīn tiào tíng zhĭ wŏ cái fàng qì nĭ]
Expressed dramatically in terms of love, it states that 'only will I abandon you when my heart stops beating', implying an unrelenting level of loyalty or undying affection where death (heart stopping) is seen as the only point where devotion could end.
