“Glory to Hong Kong” “願榮光歸香港” is a song composed and written during the 2019-2020 protests in Hong Kong.  It was used as an anthem of the protests, some considering it a "national anthem" of Hong Kong. The original in Cantonese was adapted in many different languages. These two images are from the orchestral version performed by people wearing gas masks.
