Liu Chunbing’s “Ambiguity” (paintings) describes various acts which happened in night bar, particularly a variety of men and women of desire, and all kinds of intimacy and even indulgence between male and female. In the aspect of artistic expression about feeling, sex and their relationship, there are many ambiguities which are difficult to distinguish obviously. And feeling often becomes a beautiful piece of fig leaf for rampant sex. But as a possible salvation, many arts point to and deeply critisize the emptiness and boredom of people’s life. In fact, Liu Chunbing’s artworks did not give up the position of criticism.
