From Pushing Hands (1991) to Lust, Caution (2007), there are very multiplicate modes in Ang Lee's films that they have displayed the ”cross-border” characteristics of movies. It is the multiplicity to exhibit the interpretation of cultural identity that Taiwan has been interlaced with globalization and postmodernization. In this article, I argue that the ”cross-border” characteristics of Ang Lee's films represents a mixture of cross-culture and esthetic reflection of humanity in contemporary ”aesthetics-political” situation. In other words, the directorial philosophy of Ang Lee is connected with oriental ideas and western culture and aimed at describing the common feeling and understanding for human nature by his movies. The thick humanism of Ang Lee's thought has gone beyond the border of nation-state in artistic meaning. In his ten movies, they both represented developing roles of film industry under globalization and created postmodern multiculturalism space of cross-border integration.
