Yu Aijun’s works emphasize on the physical instead of knowledge or intelligence. He believes that all visual artists, especially painters, are very concerned about the choice of image. Although it is also very critical in his creation, his creation tends to be variable, even stressing on “variability”. In his eyes, image is a primer. It is only responsible for prompting the problem. Although the choice of image sometimes depends on practicality and even emotional attribution, eventually it falls onto the way and angle they are used, the interference of the image, and individuality. The works Yu Aijun created here are painted on blueprint paper with mixed media. The misleading information on the blueprint paper will cause image ambiguity and time texture. Yu Aijun considers his works are something between sketches, oil paintings, poems and installation.
