不是所有的狗我都送她骨头
[bù shì suŏ yŏu de gŏu wŏ dōu sòng tā gú tóu]
A metaphorical statement which roughly translates into 'Not all the dogs get bones from me.' Here ‘dog’ can be considered as a figure of speech implying not everyone will receive favors from this person; there are selective boundaries set on generosity or intimacy.
