感动是毒深爱是罪
[găn dòng shì dú shēn ài shì zuì]
'Gandonshidu Shen'ai shizi' meaning 'being moved by love is poisonous; deep affection is a sin' conveys an idea that feeling strongly affected emotionally can be as harmful as poison and falling deeply in love might bring pain like committing sins, signifying intense, almost bittersweet romantic sentiments.
