On February 5, 1989, at the opening of the China Avant-Garde Exhibition at the National Art Museum of China in Beijing, a young performance artist by the name of Xiao Lu fired two gunshots at her work, two telephone booths with figures engaged in conversation inside. Her act -- part of the performance piece titled "Dialogue" -- became synonymous with the exhibition, caused the entire show to be temporarily shut down, and contributed to her and her boyfriend's arrest.
