衬何心安人不如故
[chèn hé xīn ān rén bù rú gù]
'Heart Ease is hard for the one who isn't as good as before'. This conveys that sometimes, no matter how things change and whoever is around us, none can compare with what we had. A hint of yearning or melancholy might be felt in such a nickname, showing the user's tendency toward memories and old relationships.
