Introduction to Mingguan: The Ming Dynasty was an important period in the history of winemaking in my country. The improvement of distillation technology and the promotion of comprehensive utilization technology in brewing have promoted the development of employment across the country. Whether in the court or among the people, drinking was very popular, and a large number of market towns and country hotels sprung up. During the Yongle period of the Ming Dynasty, the Chief Secretary of Guizhou was established and Guizhou was established as a province. Since then, Guiyang, Zunyi and other places have become emerging commercial centers with wine shops everywhere. The sand recovery process of Moutai was the first to be formed, and the distillation technology was improved day by day, laying a solid foundation for the further improvement of Moutai brewing technology.
