The basic prototype of this series of paper art "porcelain" creations is the ceramics of the Echulian people. The material used is naturally paper, but the type of paper is a bit special, and the main color is black. The wallpaper is then processed by hand. The main purpose of choosing wallpaper of this tone is to highlight the hardness of the "porcelain" itself and some changes in light through changes in color. All the works in this series include a series of related "utensils", such as coffee bottles, goblets and ordinary glasses. The author of this set of works is siba sahabi.
