别以为揭了我伤疤我就疼
[bié yĭ wéi jiē le wŏ shāng bā wŏ jiù téng]
Literally translates to 'Don't think that by lifting my scar, I would be in pain', it means don't try and upset me because even if you bring up past hurts or unpleasant memories, I'm unaffected. It suggests a state of emotional invulnerability.
