Chóu róng literally combines 愁 (chóu), meaning 'worry' or 'anxiety', and 容 (róng), meaning 'appearance' or 'countenance'. Together, they form a noun describing the visible facial expression that reflects inner worry—such as furrowed brows, a downturned mouth, or tired eyes. It is not just any sad look, but specifically one rooted in concern, uncertainty, or distress about a situation.

This word is commonly used in descriptive writing, literature, and spoken Chinese when observing or commenting on someone’s emotional state. It often appears after verbs like 露出 (lùchū, 'to show'), 带着 (dàizhe, 'to carry/with'), or 凝固在 (nínggù zài, 'frozen on') to emphasize how worry manifests physically. While formal enough for essays, it’s also natural in everyday speech when expressing empathy or concern for others’ well-being.
