冬天能冰封住心夏天却能融化命
[dōng tiān néng bīng fēng zhù xīn xià tiān què néng róng huà mìng]
Metaphorically, winter can freeze the heart, making it cold and unresponsive, while summer has the power to melt everything including life itself. It contrasts emotional coldness with the passionate and life-affirming qualities associated with warmth.
