Starting from May 1997, Zheng Guogu found this person who is mad and has no education, in his photo piece ?Me and my teacher?. He has followed the madman in Yangjiang and took pictures of his actions at all times and places for half year. Zheng Guogu was inspired by the madman who lives on the street. For Zheng Guogu, the madman is like a living sculpture which made him realize first time that mental-disease people in everyday life should be regarded as extraordinary creatures.
These materials later became the major part of exists on the person who does the actions inadvertently, like the madman, whom Zheng Guogu calls ?my teacher?. His everyday life is included in the so-called category of art, but in fact we are not aware of the boundaries. As much as he can, in his work Zheng Guogu grasps the essence of everyday life. This is a healthy, dynamic condition, and, in certain level, a basic character of a good artist today. These artists believe in nothing but everyday life.
