Form One: Rare Beast
Tian Gou was first referred to in the "Classics of Mountains and Seas" first. Below is a snippet from the original text where Tian Gou is mentioned, followed by a rough translation:
“Another 300 leagues to the west lies Yin Mountain. The source of the River Zhuo Yu is located here and flows south into the Fan Marshlands. The River Zhuo Yu is full of marine life with patterned shells. On this mountain there lives a beast which looks like a fox* with a white head. It is called Tian Gou. The sound it makes is similar to “liu liu.” It can be used to ward off evil."
*The character "狸" to describe the shape of Tian Gou has been interpreted in different ways. Some translate it to "racoon dog", some "fox," and others to "wild cat." I personally do not understand where "wild cat" came from, but the other two are both valid interpretations in my view.
