Scholars usually focus on discussions of Shui-hu Hou-chuan into serious comments, from politic designation to historical background. In the introduction of Shui-hu Hou-chuan, however, Lu Xun evaluated this book as "Although it is a fiction Playing with Meanings, it still to come at the ideas of withdrawing from Jing dynasty". It's wondering that is Shui-hu Hou-chuan a playing works or not? Based on "parody" and "nostalgia", this paper want to reexamines the designation of Shui-hu Hou-chuan. Starting from the parody of previous fictions in Shui-hu Hou-chuan, I indicate that "entertaining" and "serious" elements both exist in this book. This sequel of Water Margin should contain the playing with meaning; meanwhile, The characters’ nostalgia in this sequel not only bring about sigh with regret in the present world, but the ideas of withdrawing from Jing dynasty to oversea. Moreover, the fragments of object lead reader to recall the familiar scenes in Water Margin. By tracing the fragments of object, which are also the narrative codes in this sequel, I outline a trajectory of the correlation between Water Margin and Shui-hu Hou-chuan.
