The outer layer of fortitude of the work covers the inner eternity, and the central style is presented as a cyclic image, which shows the inner core theme and is like an endless extension of a dream. Meanwhile, protected by outer shell, it is firm and beautiful. The exterior of the work is made of polished stainless-steel as media material, which not only reflects the insides' persistence, and the audience's figure is also reflected on the work, making them interactive and be a part of the work.
