别为他哭他不在乎
[bié wéi tā kū tā bù zài hū]
'Don't Cry for Him; He Doesn't Care': A clear stance of advising people not to dwell in unreciprocated love. In other words, there’s no point in continuing grief over someone who doesn’t value you because the tears shed won’t change anything. It expresses both a reminder and comfort - letting go and moving forward is the wisest decision in face of nonchalance.
