The centerpiece of artist Wu Tsang's show at 356 Mission is a film in which Tsang’s frequent collaborator boychild plays Qiu Jin, a feminist Chinese revolutionary executed in 1907. Tsang plays Qiu Jin’s close female friend, calligrapher Wu Zhuying. The gorgeously produced film keeps cutting to scenes of women with knives, doing martial arts. Then we see Tsang and boychild staring lovingly at each other, lost in their romance. Near the back of the room in which the film plays is a coffin-sized box holding a neon sculpture: “You sad legend,” the neon says, it’s accusatory, indulgent tone contrasting the heroic, uncritical beauty of the onscreen love story.
