Is the wolf coming a folk story or a fable?

According to Baidu Encyclopedia, Wolf is a children's fable, which comes from Aesop's Fables.

Aesop's Fables is said to be a collection of fables written by Aesop, an ancient Greek slave who was released in the 6th century BC. There are 357 stories about India, Arabia and Christianity. Aesop's Fables had a great influence on the creation of later European fables. It is not only a model of western fable literature, but also one of the most widely circulated classic works in the world.

Aesop's Fables contains more than 300 fables, most of which are related to animals. The stories told in the book are short and pithy, and the images portrayed are vivid and vivid. Every story contains philosophy, or exposes and criticizes social contradictions, or expresses understanding of life, or summarizes daily life experience. This collection of fables shows the social relations at that time by describing the relations between animals, mainly the unequal relations between the oppressor and the oppressed. Fable writers condemned the oppression of people by society at that time and called on the bullied people to unite to fight against the wicked.
