“Do they have has sex?” is a series of black and white snap shots. And the shooting process resembles a street performance. He asked an assistant to hold a panel with the abovementioned sentence in front of arbitrarily chosen couples on the street and took photos. Then, they appear to be a kind of evidence of crime investigation. He uses the powerful function of photography as a way to impose “truth” on casually grasped fragments of reality to tackle a highly sensitive issue of sexuality in a society without much space for individual freedom and intimacy. In this context, the sentence attached to their images seems to be a kind of affirmation, or even accusation, rather than a question in spite of the question mark at the end. However, the connections between the people arbitrarily related together as couples are so uncertain and unreliable that they become quasi comic. However, this is a purported imitation of the methods frequently resorted to by the authority to impose its version of reality, or the official truth, in both everyday life and political and cultural discourses. This is a kind of prejudging affirmation or accusation that one has hardly the right to argue against. By appropriating this strategy, Zhu Jia once again puts scepticism of the imposed truth at the very centre of the pubic gaze.
