心软嫑命

It's a combination that means something along the lines of ‘too soft-hearted is not long for this world’. While 'heart too weak' ('心软') refers to a kind and tender nature prone to sympathy, the internet slang term ‘嫑’ (meaning 'don’t') followed by ‘命’ represents a casual statement on survival or living, suggesting this overly compassionate attitude may somehow lead one into danger or unfavorable situations due to its naivety. However, it's important to note that this phrasing includes modern internet jargon which makes it less formal than traditional Chinese expressions.
