This work, I would like to present the feeling of searching for the trace by sounds. Covered by white color, the surface of painting becomes indistinct. In the maze picture, the neighboring areas beside the paths are disconnected. It is certainly the same area when entering the enclosed paths. Then I use this advantage to make the audience search for way out by sounds emitted from touching, that is to say, only the paths which can emit sounds are way out. The meaning is that, in order to seek the chances of moving forward or exiting, one must needs some methods or clues when surrounded by concealment.
