Hit Rate was initially exhibited at “Contemporary Art Exhibition in Songjiang: Bourgeoisified Proletariat” at Shanghai Songjiang Creative Studio in 2009. About thirty hundred of pingpong balls, with over two hundred kinds of fatal illness printed on them, were installed in the glass-roof over the stairs in the exhibition room, connected to a transmitter through a few of transparent plastic pipes. The pingpong balls were ejected out of the pipes every 3 to 5 seconds, and dropped around the show room. Visitors might be “lucky” enough to be hit by certain disease or just walk through them. Here in this special version of much reduced dimension, on the other hand, all the "illness" is kept in a space paved with mirrors that reflect each other. Appearing to recede into multiplied eternity, the balls unfold a list of all possible risks, either physical or psychological, that we may be about to confront. Akin to "I Will Die" which bespeaks YANG Zhenzhong's concern with the issue of death, Hit Rate also stands as an interpretation of facts that we feel extremely reluctant to be faced with. Whatever our wishes, we are already involuntarily parts of inescapable circle. Don't be frustrated, however. It is simply another melodramatic and game-like hint dropped by the artist: perhaps all of these is merely a game made of numerous pingpong balls.
