During Spring and Autumn Period, even though the religion still received the respect, the social rationality had a very big development. As the representative of social value, the official historian must simultaneously undertake the religious tradition and the realistic rational spirit. "Annals of Zuo" has two different narrative methods: The symbolism narrative and the rationale narrative. The symbolism narrative and the rationale narrative. The symbolism narrative mainly includes the mutation event and the divinity behavior. The mutation event and the divinity behavior may be regarded as a kind of representationof the gods will, thus hide the fortune and misfortune of the world. Therefore such narrative methods also prove the existence of religion, and seek the basis for the moral rationality. On the other hand, the offical historian believed that, any event may be attributed to somebodys earlier motive or character reason, and these motives and characters should be responsible for the event. According to this logic, the future event or the life destiny also may be extrapolated from the small event. Therefore, "Annals of Zuo" has very many records of the prediction. Regardless of symbolism narrative or the rationale narrative, both of them are the methods of reality demonstration and the access to the voice authority by the official historian of Spring and Autumn Period.
