旧梦滥人心旧人不覆彻
[jiù mèng làn rén xīn jiù rén bù fù chè]
'旧梦滥人心旧人不覆彻' means roughly that 'Old dreams play tricks on people’s hearts; past love cannot be relived thoroughly'. Through this poetic handle, the user seems to express remorse over nostalgia playing on his/her emotion. The sentiment evoked is bittersweet – cherishing past affection while realizing it can't return entirely as it once was, thus conveying a profound nostalgia with a touch of resignation about lost relationships and youthful fantasies.
