there are two kinds of packaging in Yuxi, 22 yuan because the packaging versions are different. There are two versions of the package of Yuxi cigarettes, namely, hard box Yuxi cigarettes and soft box Yuxi cigarettes. Early cigarettes were all packed in soft boxes. In the 197s, Shanghai Cigarette Factory introduced hard box packaging machines before hard box cigarettes came into being. Compared with the soft box, the advantage of hard box Yuxi cigarettes is that they are placed in the pocket. Because of the protection of the cigarette case, the cigarettes inside are not easy to be squeezed and broken.
