The art and technique of casting Han-period bronze mirrors reached a peak in the so-called TLV sishen mirrors. The decoration consists of two major components: ornament and inscription. Both components comply with certain rules while leaving some room for customization and free options. This program aims to deepen the understanding of these rules and freedoms. You are asked to design a mirror by filling into the blank zones certain decorative elements listed on the left panel. Identify which elements have rules and which do not and place the selected elements in proper ways.
