The Chinese term **"號愬"** can be translated to English as **"to cry out in distress"** or **"to wail in anguish."**

- **號 (háo)** means "to howl" or "to cry loudly."
- **愬 (sù)** conveys "to complain" or "to express grievance."

Thus, the combined phrase suggests **a loud, sorrowful outcry**, often due to suffering or injustice. Depending on context, it could also be rendered as:
- **"to lament bitterly"**
- **"to wail in protest"**
