万箭穿心够不够五马分尸都不够
[wàn jiàn chuān xīn gòu bù gòu wŭ mă fēn shī dōu bù gòu]
Even pierced by ten thousand arrows and being torn apart is not enough (meaning this is an exaggeration used to show great pain or regret). It indicates extreme emotional turmoil and deep sorrow over someone or something lost or failed.
