思念太长爱你太短
[sī niàn tài zhăng ài nĭ tài duăn]
In English it means 'thinking of you lasts so long but loving you seems such a fleeting moment', indicating a feeling where someone misses or thinks about another too much while also believing the time for love passes very quickly - this can imply either regret or a sense of cherishing each brief moment together with loved ones
