狐狸未成精纯属骚的轻狐狸已成精纯属狐狸精
[hú lí wèi chéng jīng chún shŭ sāo de qīng hú lí yĭ chéng jīng chún shŭ hú lí jīng]
A playful saying: if the fox hasn't fully transformed into an evil spirit (essence), it may just mischievously cause disturbances. Otherwise, a fully developed fox would become a genuine demon or enchantress. It alludes to varying degrees of charm or danger within oneself or another.
