First of all, from the historical origin, China's ancient fables can be traced back to the Spring and Autumn Period and the Warring States Period, while Aesop's fables originated from the traditional culture of ancient Greece. Secondly, on the theme, China's ancient fables mainly involve the relationship between man and nature, man and man, and man and society, which reflects the concern of China traditional culture for morality, ethics and law. Aesop's Fables pays more attention to the reflection on human nature, and probes into the weaknesses and mutual rights and interests of human nature. In addition, in the form of language, China's ancient fables often take the form of poetry or prose, which is more beautiful and euphemistic; Aesop's fable is a form of fable (other words), which is concise and clear. Finally, in the way of expressing morality, China's ancient fables often express morality through metaphor or symbol, which reflects the implication of China's ancient culture. Aesop's fables, on the other hand, express their concern and criticism of human nature by satirizing and mocking stories and characters.
To sum up, there are obvious differences between China's ancient fables and Aesop's fables in historical origin, theme, language form and moral expression. But both of them convey the wisdom and enlightenment of morality, ethics and culture through fables.
