单纯的孩纸你们伤不起
[dān chún de hái zhĭ nĭ men shāng bù qĭ]
'单纯的孩纸你们伤不起' (chún dān de hái zhi nǐ men shāng bù qǐ) can be translated to 'innocent kids, you cannot afford the hurt'. It reflects that children with simple minds cannot bear some emotional wounds. Also, '孩纸' is a cute way of writing '孩子' (child).
