Drawing lessons from the production process of cloisonne in Ming Dynasty, during the Kangxi period of Qing Dynasty, craftsmen painted and decorated the tires of copper, glass, utensils and porcelain with imported enamel color materials, and created a variety of enamel vessels, among which the painted enamel vessels of porcelain tires were enamel colored porcelain, commonly known as "Guyuexuan" porcelain. It is specially designed for the concubines in the palace to enjoy and use in religious and sacrificial occasions. It is a very precious palace with little output and few handed down products, and has always been regarded as a rare treasure.
