多少红颜为狗比多少狗比不珍惜
[duō shăo hóng yán wéi gŏu bĭ duō shăo gŏu bĭ bù zhēn xī]
A very colloquial statement criticizing how many beautiful women are treated badly and how little some people appreciate them. It's an expression of anger towards social issues, with somewhat harsh wording to make the point strong.
