The brewing techniques of Maotai liquor and Zheng Xiong Maotai-flavor liquor are related to the Gelao nationality. What's the difference?

Gelao people have a long history of wine-making skills, which is an intangible cultural heritage of Guizhou. Among them, Maotai followed the brewing technology of the Gelao nationality and revised it, while Zheng Xiong insisted on the traditional brewing technology of the Gelao nationality, and its founder, Mr. Zhang Zaibin, was the non-genetic inheritor of the brewing technology of the Gelao nationality, so Zheng Xiong Maotai-flavor wine was the original flavor of the Maotai-flavor wine.
