The difference between cultural posters and public welfare posters and commercial posters is that they are rooted in reality and convey specific information about specific time and space, which is different from the social responsibility of public welfare posters and the commercial purpose and utility of commercial posters. Cultural posters often use relaxed and pleasant graphics to stop people rushing by in the street. Designers of cultural posters often spend a lot of time and energy to create mobile phone posters for visual communication with people. In this regard, cultural posters have become posters that some of the most talented designers are willing to design.
