深入人心你害人不浅
[shēn rù rén xīn nĭ hài rén bù qiăn]
The phrase 'Deeply Affected, You Have Harmed Not Shallowly' suggests someone left a deep impression due to causing emotional damage. It conveys the message of significant impact caused in one’s life, often negative, but impactful enough to remember for a long time.
