Cao Shu's works pay close attention to the intrinsic root of the artistic language and strive to find the most primitive origins. In recent years, his animation and video installation works have developed new directions, particularly in the understanding of new medium and technology. Although Cai's use of the medium is diverse, the focus has been primarily on the relationship between the public space and the individuals, such as symbols and individuals, Internet and individuals, the collective history and individuals, etc.
