你是狐狸精我怎敢跟你比
[nĭ shì hú lí jīng wŏ zĕn găn gēn nĭ bĭ]
Translated loosely as 'You're a fox fairy, how can I dare to compare with you?' This comes from a Chinese mythological reference to beautiful, alluring, and mischievous spirits called fox fairies ('huli jing'), indicating someone is so charming or clever that the person feels unworthy by comparison.
