In the early days, foreign tobacco companies in China focused on decoration and cigarette label design when producing cigarette trademarks. They often used oil painting techniques, and a few used gouache paintings and woodcuts. They were characterized by fine workmanship and good effects. The cigarette powder belongs to the 3401 group of the 34th category of the trademark classification, and the sub-item number is: C340002. According to statistics from Lubiao.com, there are 3,764 registered trademarks for cigarette powder. Trademark is a specialized legal term. After a brand or part of a brand is registered by the relevant government departments in accordance with the law, it is called a trademark.
