Pragmatic identity is chosen and constructed by the speaker on a specific occasion to achieve his owncommunicative purpose. Pragmatic identity is integrated in various fields, but there is little connection withsociology. Language landscape is an important branch of sociolinguistic research. Based on pragmatic identitytheory, this paper intends to explore the characteristics and functions of language landscape, and investigate theconflict between pragmatic identities. The study shows that the slogans of political demonstration have thefollowing four characteristics: powerfulness, conciseness, vividness, and passion. Its function is consistent with thepurpose of the demonstration. The subjects of the study dynamically chose new pragmatic identities in thedemonstration, which conflicted with their previous pragmatic identities.
