Why do some of the new Anhui cigarettes have different slogans?

It may be that the warning language has been changed. Manufacturers sometimes change parts of the product from time to time. This is normal.

As long as the cigarettes have no other connotations, feel free to use them. I have collected many old cigarette boxes. It is normal for the same brand to have changes in different years. It is caused by the manufacturer redesigning and printing in order to better manage this brand.
