Working simultaneously on the same sheet of xuan paper, the two artists unfold a prolonged visual dialog. Using a ruler, Hung traces parallel lines that stutter in dots; Wai draws fluent, freehand curves that coalesce into billowing waves. These two kinds of lines stage innumerable fleeting dramas of attraction and repulsion, alliance and antagonism. By turns they define and transgress territories, deface each other and interweave into new structures, creating a dense record of otherwise inarticulate nuances of human relationships.
