Is flying not suitable for us? Albeit we are suitable for swimming, for surfing, for mountaineering, and even for landing on the moon! Isn't it true that flying is not for us because we are afraid of falling down? Or, do we finally admit that we can't fly? Flying is for other kind, but not our kind. Besides flying, what other activities are not for us? By narrating a story, Ying-shu Cheng explores the raison d'être and the jokes and doubts about sex, gender, desire, and identification in her Flying Is for Us. In an attempt to uncover the incompatibility between desire and social relations through analysis and discourse, in this work, Cheng focuses on the following five aspects: "the discourse between text and sub-text," "the construction, deconstruction, and reconstruction of gender," "the dissociation and filling of family value," "image shaping and kitsch strategy," and "the stagnancy and collapse of the reason of existence." Human life is repetition. Besides getting away from physiological and gender constraints, we can reverse them through cultural and gender identification. It is an opportunity to reshape oneself and to repair the concept of social value.
