“龍眉”在英文中沒有直接對應的固定譯法，但可以根據具體含義靈活翻譯。以下是幾種常見處理方式：

1. **直譯 + 解釋**（適用于描述外貌特征）：
- **"Dragon eyebrows"**
*示例：He had thick, arched eyebrows known as "dragon eyebrows" in Chinese culture, symbolizing authority and power.*

2. **意譯**（若指英武的眉型）：
- **"Heroic eyebrows"** 或 **"Imperial eyebrows"**
*示例：In traditional Chinese面相, dragon eyebrows refer to thick, straight eyebrows that signify leadership.*

3. **文化意象轉換**（若強調威嚴）：
- **"Majestic eyebrows"** 或 **"Commanding eyebrows"**
*示例：The character was depicted with dragon eyebrows, adding to his majestic appearance.*

具體選擇需根據上下文。若指文學或面相學概念，建議保留拼音 **Longmei** 并加注釋，以保留文化特色。需要進一步優化可以隨時告訴我。
