人亡心未亡人凉心未凉
[rén wáng xīn wèi wáng rén liáng xīn wèi liáng]
It translates to 'though a person is dead, his heart is still alive; though one's life gets cold, their heart does not.' It expresses that even if someone passed away or fell from power, they remain unforgettable or deeply cared for in others' hearts.
