Shuttling through the image slices of the past and present with characteristics of the times and special environments, the form of "old and new" contrast allows the senses to transition from one state to another, creating a feeling of "enlightenment" for the viewer. Through the process of comparing with the viewer's own experience, a "gradual enlightenment" effect is produced. Leaving the development process of things between time points and the unknown information of the development direction of things after time points to the viewer's imagination, the juxtaposed images are given a narrative quality. Through this continuous reflection and experiential recognition, the connotation that the images want to express is savored and deeply understood.
