Fox: The name of the animal. Fox and raccoon are two kinds of animals. The back joint refers to the fox. Often referred to as a treacherous and cunning bad guy.
"Dongguan Hanji Biography of Zhang Gang": "Zhang Gang, the imperial censor, buried his wheel alone in the Duting Pavilion in Luoyang, saying: 'The jackal is in the way, so ask the fox!'" The poem "Jiu Ke" by Du Fu of the Tang Dynasty: " There is no way for foxes, but jackals and tigers are running rampant." Chapter 13 of "Shuo Yue Quan Zhuan": "A proud fox is as strong as a tiger, but a defeated parrot is not as good as a chicken." Chapter 2 of Yuan Jing's "Red Traffic Line": "Xu Yaoming is really like that." "Old fox."
In fact, I also saw in the explanation of the word raccoon: raccoon means "raccoon dog". One day is like a raccoon dog, and the other is a fox, which is called Gongziqiu.
——"Poem·Binfeng·July"
This is probably the earliest occurrence of the word fox, which comes from the Book of Songs
