Yang Zhenzhong adopts the public transportation facility which possesses the warning significance, traffic lights, more precisely, the dynamic pedestrian signal lights as his exclusive artistic presentation. Multiple pairs of lights are lined up in a space, numerous red/green icons are constantly overlapped with each other, like a group of people walking from nowhere but commanding by “quick step” and “halt”, therefore, leads to an unknown destination. The strangeness has been generated when the common outdoor signals have been shifted into indoor, thus, the entire piece of work has transformed into a carnival like absurd line-up.
