杀了你我百毒不侵杀了我你刻骨铭心
[shā le nĭ wŏ băi dú bù qīn shā le wŏ nĭ kè gú míng xīn]
'Kill me and you are invulnerable. Kill you and my feelings will be indelible'. Expressing extremes and intensity of feelings towards someone, this phrase shows a very dramatic perspective on relationships and their effects on one's soul.
