For the most authentic Qinghai Huzhu Barley Wine Co., Ltd., you must look for the factory address: No. 6 West Street, Weiyuan Town, Huzhu County, Qinghai Province. Don't think of No. 8 South Street as a mess. Other brands of wine are not very good. Its Tianyoude and Bada Workshop are more famous! Zhenzong Liquor can be authenticated by sending text messages. I hope it can help you
