一抹残阳卸了谁的红装
[yī mŏ cán yáng xiè le shéi de hóng zhuāng]
Literally means 'a streak of setting sun takes off someone’s red dress'. In metaphor, it could be describing a fleeting moment of beauty caught at sunset or evoke the sense of time passage marking changes in personal life circumstances such as growing up or losing something valuable.
