披: "Pí xīng dài yuè" (to toil day and night) embodies the spirit of diligence and perseverance, often used to describe someone working tirelessly, as if carrying the stars on their shoulders and wearing the moon as a crown. "Pī kāi, liè kāi" (to split, to crack) conveys the act of dividing or breaking apart, a phrase that carries a sense of force and transformation, yet its use should be approached with caution, as it implies a significant and often irreversible change.

室: Classroom, chamber.
