时光未老爱意微凉
[shí guāng wèi lăo ài yì wēi liáng]
'时光未老' refers to the passage of time which has not yet aged things excessively. '爱意微凉' describes affection that has become somewhat faint and cool; the entire expression can be interpreted as a kind of romantic lamentation that even as memories fade and ardor subsides over years gone by, they haven't completely vanished and carry their own mellow beauty.
