心若丢失人亦忘
[xīn ruò diū shī rén yì wàng]
It literally translates as 'if heart lost, then the person forgotten too', suggesting a strong connection between losing emotion or feeling for someone (the heart), which leads to forgetting that individual (possibly moving on or distancing oneself after experiencing heartbreak). It conveys a sense of resignation after a loss in love, or letting go.
