the concept of taking stamps in packaging design. The "stamp" on the cigarette pack is novel and unique in design, with great collection value, which brings you an unprecedented new feeling. On the front of the package is a red "stamp" with the LOGO of Double Happiness, the trademark of "Double Happiness Cigarette" and the words "Post Happiness". The homonym of this postal greeting is Youxi, and the back of the package is still a stamp with the former site of Nanyang Brothers Tobacco Company in Hongkou District, Shanghai. It looks very grand and full of history.
