巴黎的雨湿了我的心伦敦的雾迷了我的眼
[bā lí de yŭ shī le wŏ de xīn lún dūn de wù mí le wŏ de yăn]
Translation: 'Rain in Paris has soaked my heart, and the fog in London has clouded my eyes.' It depicts feeling overwhelmed by sadness or confusion in foreign cities, metaphorically comparing these feelings to weather conditions.
