To find long-lost innocence, we hold hands in a circle to swing free in a world of fantasy. Inward swinging represents everyone sticking together, and outward swinging stands for exploring the outside world. The installation site was the location of Feng-Yuan shrine during the Japanese occupation. Therefore, we arranged the materials symmetrically within the block. Another set of objects is placed in the center to achieve concentricity and to preserve the ritualistic atmosphere of the shrine. We were inspired by the elements of a swing set as a presentation topic, using the interaction between one person and a crowd as a connection to arrange the pieces according to yin and yang, male and female, and moving or still to present the overall atmosphere.
