What is it behind the closed window and what can be seen from it? Photographer Kuo Ying-sheng transcends time and space and opens another window onto Haian Road with the photograph of the window on the red wall at Confucius Temple in Tainan. The still and quiet window view matches the image of Tainan, the ancient capital city, the inner serene while presenting the freedom of infinite extension. At the bottom of the window, there is a small potted plant cultivated at the initial stage of the establishment of the Art Museum on Haian Street and adjacent to the potted plant, a mottled wall shows the long years of wear. Cared for voluntarily by shop owners nearby, the potted plant is still healthy and growing and enables an interactive change between the scene and the artwork.
