Today we will again be deeply impressed by the memories and imaginations about Chinese culture in the novel The Ancestor Game of Alex Miller for which he has won several awards. All are so vividly described and expressed by an Australian writer who has never been living so long in China. We cannot help asking what is the significance of the memories and imaginations in the text concerning Chinese culture. The author will try to decode the prize-winning novel from the perspective of cultural memory and imagination based on the German scholar Jan Assmann's cultural memory theory so as to find out the profound connotation embedded in it and the role played by it in the restructuring of Australian culture.
