1. Heilanzhou, with two lines on the back, is a new cigarette produced in recent years. Most cigarette packs produced after 20 15 to 20 16 are printed in two lines.
2. Heilanzhou with three lines on the back is the batch with earlier production time, so it is necessary to pay attention to the possible moisture problem.
In short, whether it is the second or third line of Heilanzhou, we can't judge its authenticity by this, only that its production batch is before and after.
