What does ckk at the bottom of Maotai bottle mean?

It is the code of the factory that produces wine bottles.

The symbols MB, HB, CKK and mouth at the bottom of the bottle are actually the codes of major Maotai bottle manufacturers, and there is no special anti-counterfeiting function.

The font of genuine Maotai is full, three-dimensional and clear, and there is generally no problem. However, the identification of Maotai can't completely look at the bottom of the bottle, because it doesn't rule out the existence of individual defective products in some assembly lines, or it may be that some unscrupulous vendors are not easy to see because of their high counterfeiting technology. Therefore, the identification of Maotai should be viewed comprehensively, such as bottle mouth code, Fei Biao, bottle bottom and so on.
