This study analyzed popular music from Hong Kong that emerged after the 2019 Anti-Extradition Bill Movement, investigating how social scars are represented in song lyrics despite government restrictions on free speech. This study focused on three narrative strategies from Chinese Scar Literature—silence, lyricism, and coded writing—in its an analytical framework. The study investigated how these strategies have contributed to the creation of a unique coded system within the constraints imposed by the government. The findings reveal similarities between the narrative features and coded systems of postsocial movement Cantopop and Scar Literature. However, the coded system in popular music from Hong Kong is more concealed and requires a higher threshold of background knowledge for interpretation compared with Scar Literature. This study considered postsocial movement Cantopop to be a form of Scar Literature, which enabled interpretation of such popular music in the aftermath of social movements from a novel perspective.
