年轻时用心去爱着年迈时用心去回忆
[nián qīng shí yòng xīn qù ài zhe nián mài shí yòng xīn qù huí yì]
Translated as 'In youth we fall in love wholeheartedly, in old age we reminisce wholeheartedly.' This expresses two key phases of a life: passionate love and deep, meaningful recollection. Suggests a cycle wherein heartfelt experiences in both eras add profound value and meaning to life.
