Introduction to Dark Fragrance Floating: In the Song Dynasty, the increase in population, the prevalence of tea-drinking customs, and the large demand from overseas markets further promoted the development of Guangxi's porcelain industry. The products of Guangxi's Song Dynasty porcelain kilns pursued the style of famous kilns from other places and at the same time were innovative, showing strong local color. The porcelain kilns along the Luoqing River in northern Guangxi mostly imitate the northern kiln mouths and belong to the Yaozhou kiln celadon series; the porcelain kilns along the Beiliu River in eastern Guangxi mostly imitate the southern kiln mouths and belong to the Jingdezhen blue and white porcelain series.
