In this paper, we studied on the history and structure of Chinese myths centering around Pan-gu myth. The existence of creation myth has become a big issue in Chinese mythology. Pan-gu myth is very important in relation with this issue. the results of this study is as follows. First, we came to know that Pan-gu myth was appropriated by Daoism later age when we analyzed historical texts about Pan-gu myth. It means Pan-gu myth has an original position on Chinese ancient culture. And we abstracted 4 mythemes―chaos, the birth of Pan-gu, the beginning of world, the change of Pan-gu corpse―from the historical texts. Secondly, we ascertained that 4 mythemes of Pan-gu myth have a general meaning of creation myth. But we can not exclude the possibility that the meaning of natural death was controlled by the humanistic viewpoint later age. And we can read the structure of Pan-gu myth as the relation of creation / destruction, nature / human, unconsciousness / consciousness, other / subject. Lastly, we hope that we will enlarge the textual extent to the oral texts of ethnic groups in China afterwards.
