捂着半边的心脏停止跳动
[wŭ zhe bàn biān de xīn zàng tíng zhĭ tiào dòng]
This dramatic saying imagines holding onto a half-heartedness till heartbeat stops - signifying a heartbreak so intense it feels like the heart is halting, or having mixed emotions that only occupy part of one's emotional being until nothing left to feel anymore.
