Unpretentious introduction: During the Wei, Jin, Southern and Northern Dynasties, Guangxi was relatively stable and peaceful, and the porcelain manufacturing industry continued to develop. During this period, the porcelain produced in Guangxi was mainly celadon, which belonged to the southern celadon system. During the Sui and Tang Dynasties, Guangxi's porcelain production developed rapidly. Porcelain is mainly celadon, and its shapes and glaze colors are richer than before. Glazing less than the bottom (commonly known as "half-glazed") is a typical feature of the utensils of this period. Generally, the upper half of the utensils are glazed, and the lower half exposes the gray-white fetal bones. The glaze often shows fine cracks.
