似水流年空荡
[sì shuĭ liú nián kōng dàng]
Translates as 'The fleeting years pass by leaving emptiness', which poetically signifies the passage of time in a somewhat desolate manner. Years go by with nothing much left behind, suggesting either wistfulness for the passing time without tangible outcomes or contentment with leading a tranquil life that doesn’t strive for achievement necessarily.
