The slogan is to express a meaning in concise language in order to achieve a certain propaganda purpose. The role of slogans is to "create momentum" and form an atmosphere, and it is also easy to play the role of "safety notice". In 1930s, the Red Army wrote a large number of propaganda slogans on the walls of houses in various base areas, many of which still exist today and become red cultural relics. Slogans reached their climax during the Cultural Revolution. Slogans have obvious characteristics of the times and industries, such as "family planning" slogan and "forest fire prevention" slogan. The purpose is very clear, either to publicize a certain policy or to advocate a certain idea, such as "whoever burns mountains will go to jail" and "to get rich, have fewer children and plant more trees". Slogans are generally catchy and rhythmic.
