洋葱没有心却能让人流泪
[yáng cōng méi yŏu xīn què néng ràng rén liú lèi]
Translates into 'Onions do not have hearts but make us cry.' A poetic analogy reflecting how superficially emotionless things or actions might cause real emotional distress, showing that sometimes even impersonal or unintentional actions can result in profound human sentiment.
