Relief works are that each sculptor uses oily soil to roughly shape and carve, then turns and presses into gypsum board, and then carves details on the gypsum board; its entire production process and technique are similar to ordinary sculpture production. Hand-shaped relief is also an important factor in the quality of product technology. The fineness of relief is completely directly reflected in the final product. This requires that every relief work can perfectly present every detail and be carefully carved everywhere. In addition to its own value, the relief works have achieved rich artistic value.
