To enable young people to receive messages about environmental protection, advertisements must be made in the language of young people. Therefore, strong colors and fonts are used in the poster to make the poster more eye-catching in the canteen. Secondly, I also used some trendy language and produced a series of posters in a self-questioning and self-answering model. Finally, to strengthen college students’ memory of Friday, we will first publicly announce the posters, and then display the entire series of posters on Friday.
