吹不散眉弯抚不平眉头
[chuī bù sàn méi wān fŭ bù píng méi tóu]
Meaning ‘Worries that no wind can disperse, furrows in the brows that cannot be smoothed away,’ this poetic expression signifies persistent anxieties or deep-set concerns which are metaphorically illustrated through unsmoothing frown lines on the face.
