1. ** Observe the packaging * *. Real cigarettes are beautifully packaged, look new and have bright luster. Fake cigarettes, on the other hand, look old, like they have been placed for a long time, or the cigarette case looks dim.
2. ** Check the trademark * *. Unpack the cigarette case and study the trademark of the cigarette carefully. The trademark handwriting of real cigarettes is clearly printed, and the signs of strips and packets are exactly the same. The trademark printing of fake cigarettes is rough, and the font is small or vague.
3. ** Smell the cigarette * *. Real cigarettes are slightly tobacco-flavored, and other flavors should not be. However, the fake cigarette essence has a strong taste or no taste at all.
4. ** Observe the packing direction of cigarettes * *. Real cigarettes are packed ten to the left and ten to the right. And fake cigarettes are twenty cigarettes, all of which are packed left or right.
