We are a group of young Chinese writers and researchers who are interested in participative art and social movement. Two of us are going to give a lecture on "art scene investigation" concerning art ,politics and social environment in the Ullens centre of 798 art district in Beijing. Inside-out project will be a crucial topic of our lecture. That's why we want to show some image of it at the scene of our meeting. We want to show the Chinese people the very spirit of "art in the street, art of the people".
