Using a fox as an avatar has a far-reaching impact. On the one hand, it is to care for small animals and call for the care of wild animals. On the other hand, it also means that you want to be smarter and bring wisdom to yourself.
Third, foxes have a natural feminine personality, and their heads are often suggested as charming.
There is also a saying in modern society that "everything has its vanquisher", which means beware of "mistress".
