不知我心怎知我人
[bù zhī wŏ xīn zĕn zhī wŏ rén]
Translates as 'how do you know me if you don't know my heart'. This phrase conveys the notion that one must truly understand someone’s inner thoughts and feelings before claiming to truly understand them. It suggests authenticity and depth within the self that cannot be seen easily from outside appearance or actions.
