Is the Gelao nationality's wine-making technology very good? I heard that Maotai brewing technology originated from the Gelao people?

In BC 135, the Gelao people brewed the first jar of maotai-flavor liquor. In AD 1953, Maotai revised the brewing technology of the Gelao people, and Shine on You was born. As the earliest nation to make wine, the technology of making wine can be seen. Maotai is not the only wine brand that still insists on using Gelao brewing technology. Zhang Zaibin, the founder of Zheng Xiong Maotai-flavor liquor, as the non-genetic inheritor of the brewing technology of Gelao nationality, has always insisted on using the original brewing technology of Gelao nationality. If you want to taste the original flavor of Maotai-flavor wine, you can try Zheng Xiong Maotai-flavor wine.
