不刻骨怎能铭心
[bù kè gú zĕn néng míng xīn]
'Bù kè gǔ zěn néng míng xīn' translates to something like: 'If not deeply imprinted (engraved), how can it remain at heart (be memorably)?' The saying stresses the idea that meaningful experiences must make a profound impact if they are to be truly remembered or treasured within one’s heart.
