Artworks of eggshell carvings and decorating are on display at the first Changzhi Agricultural Cooperation and Development Expo Week in Changzhi city, Shanxi province, Sept 23. There are two types of eggshell decorating. One involves carving figures and scenery patterns on dark eggshells with carving knives, where the effect of patterns is similar to the sketch or outline once finished. The other is to carve on thick shells of eggs like ostrich eggs in bas-relief or hollow-out manner. [Photo/news.cn]
