你若是狗尽管把我看低
[nĭ ruò shì gŏu jĭn guăn bă wŏ kàn dī]
This means 'If you are a dog, then underestimate me all you want,' expressing defiant humor. The person adopts a challenging stance toward someone who perceives them negatively, telling them that even if viewed lowly it won't affect their dignity or worthiness.
