太阳暖人不暖心月亮凉心不凉人
[tài yáng nuăn rén bù nuăn xīn yuè liàng liáng xīn bù liáng rén]
'The sun warms the body but not the heart; the moon cools the heart but does not chill the person'. This is an artistic way of expressing contrasted emotions and physical warmth - how sunshine brings bodily warmth but can feel emotionally distant, while the cool moonlight soothes the mind yet physically one stays unchanged.
