The "Lines of the Mountain" series of works projects the thought processes of the artist onto the canvases, organizing complex emotional states into the structuralism of their compositions which allow viewers to engage in calm and simple contemplation of the works and immerse themselves in their atmosphere. Perhaps most interesting and most central to Wu's art is that, while employing the western oil medium and its techniques, along with a highly simplified and structuralist style, Wu nevertheless communicates and the sensibilities and humanist concerns of the East.
