Substance is the sole master of the universe, that is, the only entity that exists. In the view of time and space of substance, substance itself is a formal form of space, and beyond substance itself, it is relative space or other. Space exists relative to the existence of substance, and its essence is emptiness.Time exists through the existence of substance, and the measurement of substance existence is called time. The time in relativity is nothing more than clock time, which is artificially used to measure the specific form of substance existence, and therefore has characteristics of variation in different substance environments. Artist uses the accumulated form of substance movement to record the existence of events and their relationships with each other. For each of us, time records every event and their interrelationships. The sculpture series "Communicating" (2021) depict the interconnectedness of personal stories, blending cognitive, emotional, and attitudinal experiences.
