狐狸不是精只是未成行
[hú lí bù shì jīng zhĭ shì wèi chéng xíng]
Direct translation would say, 'The fox is not spirit-like but has yet to transform'. In East Asian culture, foxes can symbolize tricksters or mystical beings. By saying the fox isn't fully a spirit ('精') just yet, the nickname may imply someone still finding their true self or magical potential, growing into what they are destined to become.
