Lang Yaohong is a kind of precious colored glazed porcelain created by Lang Tingji, governor of Jiangxi during the reign of Kangxi in the Qing Dynasty, after he became a pottery official in Jingdezhen and imitated Xuande's "sacrifice to red" in the Ming Dynasty. It is one of the brightest colors in China's precious copper red glaze, which is characterized by gorgeous colors, bright red, and a strong glass luster. Because the glaze juice is thick, it flows at high temperature, so the finished product Lang Hong often reveals the white fetus on the edge of the mouth, showing a spiral white line. "
