嘴角撕扯着仅存的苍笑
[zuĭ jiăo sī chĕ zhe jĭn cún de cāng xiào]
'Mouth Twisting Into a Faint Smile.' This describes a bitter, forced smile—a kind of facial expression that signifies inner sorrow, helplessness, and emotional complexity beneath a seemingly serene surface, which may appeal especially during difficult times.
