A logistics unit is like the wheel of time, always in motion, and in this work the fastening buckle between the unit's 12-teeth wheels is ingeniously arranged. The addition of "wind" as an element and the way in which the golden wheels pass along the arched surface of the air current speaks to the constand activity of the ROC military, with the two main colors of black and white representing day and night. The message is that logistics units work all day, every day, and as such the piece serves as a spiritual focus in the camp, infusing the lives who live there with a taste of art.
