If it is the most authoritative place, you can go to the local industrial and commercial bureau, and there should be someone who is responsible for identifying the authenticity.

In addition, you can also find a Maotai store, or similar places, with strong identification ability. Guiyang should be an important distribution center of Moutai (because Maotai Town is in Guizhou), so there are many places to identify Maotai.

In addition, some wine collection websites can also find some knowledgeable collectors or dealers, and can send pictures for them to identify.
