There are foxes in Qingqiu, and there are many jade in the yang and green eagles in the yin.
There is a beast, its shape is like a fox with nine tails, its voice is like a baby, it can eat people, and those who eat it are not poisonous. There is a bird, its shape is like a dove, its sound is like a ho, its name is Guan Guan, if you wear it, you will not be confused. The Yingshui comes out, and the South China Sea pours into the Jiyi River. There are many red ducks among them, their shape is like a fish with a human face, their sound is like a duck, and they will not cause scabies when eaten.
