繁华一世你许我一世凄凉
[fán huá yī shì nĭ xŭ wŏ yī shì qī liáng]
'One life in prosperity, one lifetime's bleak promise granted by you'. The term conveys a bittersweet contrast where despite all outer wealth or glory ('prosperity') during one's lifetime there persists a melancholy sentiment as if a promise once made turned out to bring more sadness than joy over time.
