The problem of man and nature collision endangers the living world existence. In order to save nature and protect the environment, it is very important to rethink about the relationship between them. The realization of such a goal depends on the ecological literature, which helps mankind gradually realize that, this relationship is a harmonious and partnership, rather than a hostile relationship. After studying and thinking about this issue, I came to the conclusion that "The Big Fish", a very short story by contemporary Chinese authoress An Shi Liu, is a clear example of this. This work enhances people's ecological awareness and makes readers understand the two attitudes of this symbiosis (harmonious, Inharmonious).
