淡比青春凉薄年华
[dàn bĭ qīng chūn liáng bó nián huá]
'Faded than Youthful Cool Times'. This idiom represents a reflection of maturity and growing older, implying times can be more serene yet distant than those passionate and tumultuous adolescent days. One uses it usually to express a mix of nostalgia about the past and peace with current circumstances.
