I think it's exquisite to specialize in Tang tri-colors, and the most complete variety is off. Last time, a friend said that there was a genuine Tang Sancai that he wanted to show to the shopkeeper, so he went with me. Guantangxuan physical store is located at No.0/05, Handicraft Row 2, Huasheng Tianqiao Folk Culture Park, Gaobeidian. Only this company specializes in Tang Sancai, with complete varieties, good shape and good film opening technology.
Search in Baidu: Guantang pottery, Guantang tricolor and Guantang International can all be found.
