月亮凉人不凉心太阳暖人不暖心
[yuè liàng liáng rén bù liáng xīn tài yáng nuăn rén bù nuăn xīn]
'Moon Cooling People Physically But Not Spiritually, Sun Warming People Physically But Not Deeply Inside' compares natural phenomenon to complex human feelings—it suggests that although the physical warmth or chill from moon and sun may not touch the deeper layer emotions, they are metaphors for different moods and influences upon people.
