Zhuanggu Liquor is a traditional famous liquor of China, Hunan and Chenzhou Southern Pharmaceutical Factory. You see the production date 1999-2003, the manufacturer, agent and trademark are all right, so it should be true. Some are produced by 1998.

Zhuanggu wine produced after 2003 is still true, and there is nothing wrong with the winery and the wine, but you can't tell the authenticity by the above items.
