Folklore

Today at lunch, two girls were having a little argument about who was "the nine-tailed fox." I tried to help them resolve this conflict, but it was hard to understand them as their ability to use English words was limited by their escalated emotions. I ended up saying, "You can both be the nine-tailed fox." Thinking it was a game they wanted to play at recess.

Later, I found out the meaning of the nine-tailed fox:

Korean version

In Korean culture the nine-tailed fox (or the kumiho) is a predominantly malevolent being. A fox that lives for one thousand years can become a kumiho, and it often takes the form of a beautiful young woman to seduce men in order to eat their flesh: usually the liver, although the heart is also a target at times. Some tales say that under certain circumstances a kumiho can become human, and the circumstances can vary from eating 1000 men's livers to refraining from killing and eating humans for 1000 days (depending on the tale). The kumiho originates from the ancient Chinese myths and therefore shares many similarities to the Chinese huli jing and the Japanese kitsune. However, the tales of the malicious, flesh-eating foxes are more common for the Korean counterpart, although there are a few tales telling of kindly kumiho.
