As our imagination encourages us to believe, “cloud” is the symbol of fantasy, poetic and romantic. While we look at a floating cloud, we almost believe that no mundane thing can confine us. Freeing ourselves from the disturbance of the reality, we are indulged in the dream woven by ourselves. In the work “The City in the Sky,” exhibited at National Taiwan Museum of Fine Arts in Taichung until July 8, 2012 (http://www.ntmofa.gov.tw/english/showinfomation1_1.aspx?SN=3528), Artist Wang invites viewers into a world of cloud through their perceptual experience. The white cloud is beautiful and poetic, as how we imagine it, through which we dream the most beautiful dream. After waking up from the dream, we still need to return to the reality.
