The historical prototype is the witch of the northern minorities in China.

Legend has it that the weasel becomes the face of a human weasel, facing the masked body as if to attach itself to it.

This copper box should belong to daxian in mask.

What's in the copper box should be particularly important to the witch, otherwise she won't be buried with her. (Later discovered by archaeology)

When it comes to witchcraft, things always change.

It's hard to explain, just like a weasel can become a man when it's refined. In some areas where people believe in Wong Tai Sin, Wong Tai Sin is often regarded as a deity, and has the ability to protect family peace, marriage and fertility.

In some ancient tombs in Xianbei, there are murals of fairy tales of weasels.
