1, sculpture techniques are different: circular sculpture, also known as three-dimensional sculpture, is a technique in which art creates directly in three-dimensional space. The audience can appreciate the work from any angle, and the work has a complete three-dimensional space, and objects can be displayed from multiple directions and angles. Relief is a technique to create a three-dimensional image on a two-dimensional plane. Artists create three-dimensional works by shaping concave and convex shapes on the plane, and through carving is a kind between round carving and relief.

2. Printmaking is an art subject. In this discipline, artists use different technologies to print, draw images on a rigid surface (called a matrix), leave traces after leaving ink, and transfer it to another surface (such as paper or fabric) through pressure, so that multiple copies of printed matter can be obtained. Carving is the practice of cutting out patterns by cutting grooves on a hard and flat surface with a scarifier.
