亥刂乀骨铭心
[hài dāo fú gú míng xīn]
Due to some non-recognizable Chinese characters ('刂' and '乀'), it's partly misinterpreted. It should correctly express '刻骨铭心', meaning to leave a mark in the bones and engraved in the mind or indelibly impressed, symbolizing an unforgettable impact from something or someone.
