For example, retail stores often use window advertisements, catalogues, brochures, desktop printing advertisements, etc. In addition, in poster advertisements, advertisements made by traditional methods such as New Year pictures, door-to-door pictures and spring cattle pictures are very popular in the vast rural areas, and there are also packaging boxes, packaging bags and imitation films (printed with product names, uses, store names and other contents on small pieces of paper and pasted on the items for sale).
