狐狸未成精貌似太年轻吖
[hú lí wèi chéng jīng mào sì tài nián qīng ā]
Loosely translates to 'You’re a fox that hasn’t fully matured; maybe you're just too young.' Drawing on Chinese mythology where fox spirits (kitsunes) grow wiser as they age, it suggests immaturity or naivety attributed to youthful appearance.
