小心眼的男人最可恶城府深的女人更可怕
[xiăo xīn yăn de nán rén zuì kĕ è chéng fŭ shēn de nǚ rén gèng kĕ pà]
This translates as 'Narrow-minded men are the worst, women with a deep design (calculating) are more terrible'. It expresses disgust towards those considered negative personality traits: pettiness and scheming behavior in interpersonal relationships.
