In the video installation Tremble, Jiang projected the life-size images of seven naked men and women onto seven individual screens. Each person displays a different facial expression and body position such as reading a book, arms open for a hug, holding a knife, raising a fist to take an oath. Each gesture reflects some essential social aspect of everyday life: hugging is about caring, taking oath has to do with politics, reading relates to acquiring knowledge, and raising a knife indicates violence.
