There is only one family. Only Panzhou Qingming Shanghetu Wine Co., Ltd. in Guizhou Province produces Qingming Shanghetu wine. The company cooperated with Qingming Shanghetu Cultural Industry Company and obtained the authorization to produce Qingming Shanghetu wine. The wine produced by unauthorized enterprises can only use similar names and packaging, and the patterns on the Riverside Map at Qingming Festival cannot be used as trademarks. Guizhou Province is one of the main producing areas of high-grade liquor in China, with many brands such as China Moutai. The liquor industry in Guizhou Province has formed a relatively complete industrial chain, including sorghum planting, brewing and sales. In addition to Qingming Shanghetu liquor produced by Panzhou Qingming Shanghetu Liquor Co., Ltd., other high-end liquor brands in Guizhou Province are also highly sought after by consumers.
