Chinese mosaic art has a long history and unique style. In the Shang Dynasty, decorative patterns of inlaid gold and jade appeared in bronze casting. With the continuous improvement of craftsmanship, natural colored stones, pebbles, shells, mother-of-pearl, gems, jade and artificial glassware, ceramics, wood, etc. have become raw materials for mosaic. In the long-term development process, mosaic art has accumulated many important technical means, mainly including direct mosaic method, prefabrication method, reverse paste and reverse method, positive paste and positive method, etc. In addition to plane mosaic, it can also be inlaid on relief, which can further enhance the three-dimensional sense of the inlaid object. After the Ming and Qing Dynasties, the relief inlay method was widely used in the decoration of various handicrafts. In the middle and late Qing Dynasty, there was also a relief inlay method of inlaying opera characters and stories on different "grounds", such as porcelain inlay and bone wood inlay. Inlaid handicrafts have the advantages of being strong, sun-resistant, moisture-resistant and not easy to change color. The texture of the material and the resulting shape, color and light effects add artistic charm to the inlaid handicrafts, showing the rough, thick, luxurious and gorgeous beauty. Inlaid porcelain, also known as "Ju Rao", "Nian Rao" and "Ku Rao", is a kind of folk architectural decoration art popular in the Chaoshan area of Guangdong Province. It is based on painting and sculpture, and uses specially fired colored glaze porcelain pieces to stick and inlay artistic shapes such as figures, flowers, birds and animals to decorate the roofs, walls and other parts of temples and buildings. The craftsmanship of Chaoshan inlaid porcelain is unique, mostly using semi-relief or round sculpture styles, with vivid images, colorful colors, solid and stable texture, and can withstand the sun and rain without fading. In the Chaoshan area, porcelain workshops often work closely with inlaid porcelain craftsmen to fire low-temperature porcelain of various colors. These porcelains are carefully cut by craftsmen to form the porcelain pieces required for inlay, and then the porcelain pieces are assembled into partial components with adhesives. Finally, the components are combined into various patterns or statues that express folk customs, folk stories or auspicious and festive themes. Daliao inlaid porcelain and Puning inlaid porcelain are prominent representatives of Chaoshan inlaid porcelain. Daliao inlaid porcelain has a history of more than 100 years. It is mainly in Chaoshan style, with characteristics of southern Fujian. The history of Puning inlaid porcelain is even longer, dating back to the Wanli period of the Ming Dynasty.
