任谁给的温暖都高不过体温
[rèn shéi jĭ de wēn nuăn dōu gāo bù guò tĭ wēn]
The warmth offered by anyone cannot be higher than one's body temperature. It implies a sense of disappointment and indifference, meaning no matter how caring others might be, it will never match genuine human connection or warmth that comes naturally.
