Scholars have limited knowledge storage and abilities, which results in insufficient depth and breadth of research. Moreover, the overall framework of the article appears relatively immature, and there are many materials of public service advertisements collected. However, the classification of speech act of public service announcement in this paper is not perfect, and there are many deficiencies and areas that need improvement. Firstly, although this paper attempts to collect as much information as possible about public service announcement language, due to the large number of works and the rapid updating speed of public service announcement language, it is unable to provide a detailed explanation exhaustively.

Finally, the author hopes to contribute to the influence of public service announcement language creation through this article, provide enlightenment to public service announcement language creation in the linguistic aspect, and draw scholars' attention to the future development trend of public service announcement language
