一抹尘埃一季繁华落尽
[yī mŏ chén āi yī jì fán huá luò jĭn]
The fleeting nature of glory and material prosperity is symbolized here. 'Like Dust in the Air, all splendor fades with the season,' it reflects on the idea of transient beauty and grandeur eventually becoming obsolete and forgotten like dust, a sign of the passage of time.
