笨蛋你哭我心痛傻瓜你笑我快乐
[bèn dàn nĭ kū wŏ xīn tòng shă guā nĭ xiào wŏ kuài lè]
Translated as 'When you cry, foolish one, it pains my heart; when you laugh, silly one, I am happy.' This conveys the emotional connection between the speaker and the addressed person, with a touch of endearment through terms like 'foolish' or 'silly'.
