"porcelain produced in the Wanli Dynasty of the Ming Dynasty (1573mur1620). During the Wanli period, with the further requirements of the court and the upper class of society for fine porcelain, and due to the stimulation of foreign trade, the porcelain industry in Jingdezhen became more prosperous. Before the 35th year of Wanli (1607), the production of official kiln porcelain was very large, and after that, the production of official kilns in the Ming Dynasty tended to decline. The blue and white, color glaze and colored porcelain of Wanli official kiln have all made great achievements, among which the blue and white colors are the most prominent. Some craftsmen in the folk kilns in the Wanli period achieved great success in imitating ancient famous kilns and porcelain in the Ming Dynasty. "
