你貌美如花她貌美如狗
[nĭ mào mĕi rú huā tā mào mĕi rú gŏu]
You're Beautiful Like a Flower, She's Beautiful Like a Dog: This is obviously a sarcastic way of contrasting beauty levels between two people. In one's eyes, someone (likely the addressee) is compared favorably as beautiful, while another is mocked unfavorably.
