The design of the Puzzle series is inspired by children's puzzle toys and the dovetail joint in Sun Mao (meaning mortise and tenon structures in Chinese).

The overlapping mud blocks deliberately highlight and enlarge the shape that represents the image of a dovetail, forming a geometric arrangement that appears mischievous and playful yet full of childlike interest. Multiple Puzzles can be arranged and combined to form different geometric styles, allowing users to create their own three-dimensional puzzles in space.
