The paper box is a three-dimensional shape, which is composed of a polyhedron formed by moving, stacking, folding, and surrounding several surfaces. The faces in the three-dimensional composition play the role of dividing the space in the space. If the faces in different parts are cut, rotated, and folded, the obtained faces have different emotional expressions.
