The Sky Fox (Chinese: 天狐; pinyin: tiān hú), or Celestial Fox is a type of divine beast in East Asian mythology. After reaching 1,000 years of age and gaining its ninth tail, a fox spirit turns a golden color, becoming a sky fox, the most powerful form of the fox spirit, and then ascends to the heavens. With its new celestial form, it is able to see a thousand li ahead (c. 3927 km or 2440 miles).
