Abstract：On the basis of documents, this paper analyzes the influence of Buddism prevalence on Buddism recordation in the official history of Han, Wei, Jin Dynasties. During the Eastern Han Dynasty, Buddhism was ignored in Dong Guang Han Ji because of its minute influence and attachment to the traditional immortal fairy arts at the beginning of its transmission. In Three Kingdoms Period, The History of Later Han by Xie Cheng and Brief History of Wei by Yu Huan made some introductions of Buddism to help people, rulers in particular, to understand Buddism. Because Buddhism was only regarded as one of the fasting and ritual activities at that time, the introductions of Buddhism in the above two books are mainly about the Buddha. Furthermore, the conflicts between Buddhism and Taoism at that period, which were triggered by Buddhism's attempting to get rid of its attachment to Taoism, were also reflected in the two books. In the Jin Dynasty, due to its rapid development, Epoch of Eastern Han by Yuan Hong introduced Buddism with a favor of metaphysics, which is the real reflection of metaphysicization of Buddism and celebrities' understanding of Buddism during the Eastern and Western Jin Dynasties.
