"Sky", a lamp-box installation is his first installation piece. In 1998, he captured the sky over some major cities in Europe. Back in Shanghai, the artist also captured the sky over Shanghai and formed all these skies in a huge lamp-box installation. Except the shooting date, the viewers could hardly tell the difference among the skies over different cities. There is a common saying among old Chinese people "We live under the same sky and on the same earth, why you are incapable of doing something while the other are?" Does Shen describe it or visually question it? Anyway, starting from the skies over different cities, his abstract thought is connected with the urban modern aura.
