This poem was composed during Shen Quanqi's period of exile to Huánzhou (in present-day northern Vietnam) after being implicated in the Zhang Yizhi affair. Removed from court and stripped of influence, the poet used the metaphor of an "ancient mirror" to express his feelings of being buried in obscurity yet maintaining his moral integrity and unwavering loyalty to the state. In classical tradition, the mirror symbolized self-reflection and clarity; here, Shen Quanqi merges the mirror's "brightness" with his own "aspiration," revealing a spirit that holds fast to ideals and remains true to its purpose even in adversity.
